Problem-solving is an important component of any business or organization. It entails identifying, analyzing, and resolving problems in order to improve processes, drive results, and foster a culture of continuous improvement. A3 Problem solving is one of the most effective problem-solving methodologies.
A3 Problem solving is a structured and systematic approach to problem-solving that originated with the lean manufacturing methodology. It visualizes the problem-solving process using a one-page document known as an A3 report. The A3 report provides an overview of the problem, data analysis, root causes, solutions, and results in a clear and concise manner.
A3 Problem Solving has numerous advantages, including improved communication, better decision-making, increased efficiency, and reduced waste. It is a powerful tool for businesses of all sizes and industries, and it is especially useful for solving complex and multi-faceted problems.
In this blog post, we will walk you through the A3 Problem Solving methodology step by step. Whether you are new to A3 Problem Solving or simply want to improve your skills, this guide will help you understand and apply the process in your workplace.
A3 Problem Solving is a structured and systematic approach to problem-solving that makes use of a one-page document called an A3 report to visually represent the process. The A3 report provides an overview of the problem, data analysis, root causes, solutions, and results in a clear and concise manner. The method was created within the framework of the Lean manufacturing methodology and is based on the principles of continuous improvement and visual management.

A3 Problem Solving was developed by Toyota Motor Corporation and was first used in the manufacture of automobiles. The term “A3” refers to the size of the paper used to create the report, which is an ISO standard known as “A3”. The goal of the A3 report is to provide a visual representation of the problem-solving process that all members of the organisation can easily understand and share. A3 Problem Solving has been adopted by organisations in a variety of industries over the years, and it has become a widely used and recognised method for problem-solving.
The following are the key principles of A3 Problem Solving:
These principles serve as the foundation of the A3 Problem Solving methodology and are intended to assist organisations in continuously improving and achieving their objectives. Organizations can effectively solve problems, identify areas for improvement, and drive results by adhering to these principles.
Importance of clearly defining the problem.
The first step in the A3 Problem Solving process is critical because it lays the groundwork for the remaining steps. To define the problem clearly and accurately, you must first understand the problem and identify the underlying root cause. This step is critical because if the problem is not correctly defined, the rest of the process will be based on incorrect information, and the solution developed may not address the issue effectively.
The significance of defining the problem clearly cannot be overstated. It aids in the collection and analysis of relevant data, which is critical for developing effective solutions. When the problem is clearly defined, the data gathered is more relevant and targeted, resulting in a more comprehensive understanding of the issue. This will enable the development of solutions that are more likely to be effective because they are founded on a thorough and accurate understanding of the problem.
However, if the problem is not clearly defined, the data gathered may be irrelevant or incorrect, resulting in incorrect conclusions and ineffective solutions. Furthermore, the process of collecting and analysing data can become time-consuming and inefficient, resulting in resource waste. Furthermore, if the problem is not accurately defined, the solutions developed may fail to address the root cause of the problem, resulting in ongoing issues and a lack of improvement.
The first step in the A3 Problem Solving process is to clearly and accurately define the problem. This is an important step because a clearly defined problem will help to ensure that the appropriate data is collected and solutions are developed. If the problem is not clearly defined, incorrect data may be collected, solutions that do not address the root cause of the problem, and time and resources may be wasted.
A problem can be defined using a variety of techniques, including brainstorming , root cause analysis , process mapping , and Ishikawa diagrams . Each of these techniques has its own advantages and disadvantages and can be used in a variety of situations depending on the nature of the problem.
In addition to brainstorming, root cause analysis, process mapping, and Ishikawa diagram s, best practices should be followed when defining a problem in A3 Problem Solving. Among these best practices are:
Organizations can ensure that their problem is defined in a way that allows for effective data collection, analysis, and solution development by following these best practices. This will aid in the development of appropriate solutions and the effective resolution of the problem, resulting in improvements in the organization’s processes and outcomes.
Gathering data in a3 problem solving.
Data collection is an important step in the A3 Problem Solving process because it allows organisations to gain a thorough understanding of the problem they are attempting to solve. This step entails gathering pertinent information about the problem, such as data on its origin, impact, and any related factors. This information is then used to help identify root causes and develop effective solutions.
One of the most important advantages of data collection in A3 Problem Solving is that it allows organisations to identify patterns and trends in data, which can be useful in determining the root cause of the problem. This information can then be used to create effective solutions that address the problem’s root cause rather than just its symptoms.
In A3 Problem Solving, data collection is a collaborative effort involving all stakeholders, including those directly impacted by the problem and those with relevant expertise or experience. Stakeholders can ensure that all relevant information is collected and that the data is accurate and complete by working together.
Overall, data collection is an important step in the A3 Problem Solving process because it serves as the foundation for effective problem-solving. Organizations can gain a deep understanding of the problem they are attempting to solve and develop effective solutions that address its root cause by collecting and analysing relevant data.
In A3 Problem Solving, several data collection methods are available, including:
The best data collection method will be determined by the problem being solved and the type of data required. To gain a complete understanding of the problem, it is critical to use multiple data collection methods.
Once the data has been collected, it must be analysed and visualised in order to gain insights into the problem. This process can be aided by the following tools:
These tools can assist in organising data and making it easier to understand. They can also be used to generate visual representations of data, such as graphs and charts, to communicate the findings to others.
Finally, the data collection and analysis step is an important part of the A3 Problem Solving process. Organizations can gain a better understanding of the problem and develop effective solutions by collecting and analysing relevant data.
Identifying the root causes of the problem is the third step in the A3 Problem Solving process. This step is critical because it assists organisations in understanding the root causes of a problem rather than just its symptoms. Once the underlying cause of the problem is identified, it can be addressed more effectively, leading to more long-term solutions.
The process of determining the underlying causes of a problem is known as root cause analysis. This process can assist organisations in determining why a problem is occurring and what can be done to prevent it from recurring in the future. The goal of root cause analysis is to identify the underlying cause of a problem rather than just its symptoms, allowing it to be addressed more effectively.
To understand Root cause analysis in more detail check out RCA in our Lean Six Sigma Yellow Belt Course Root Cause Analysis section
There are several techniques for determining the root causes of a problem, including:
These methods can be used to investigate the issue in-depth and identify potential root causes. Organizations can gain a deeper understanding of the problem and identify the underlying causes that must be addressed by using these techniques.
It is critical to follow these best practices when conducting root cause analysis in A3 Problem Solving:
Organizations can ensure that root cause analysis is carried out effectively and that the root cause of the problem is identified by adhering to these best practises. This will aid in the development of appropriate solutions and the effective resolution of the problem.
Developing solutions is the fourth step in the A3 Problem Solving process. This entails generating ideas and options for dealing with the problem, followed by selecting the best solution. The goal is to develop a solution that addresses the root cause of the problem and prevents it from recurring.
A3 solution development Problem solving is an iterative process in which options are generated and evaluated. The data gathered in the previous steps, as well as the insights and understanding gained from the root cause analysis, guide this process. The solution should be based on a thorough understanding of the problem and address the underlying cause.
There are several techniques that can be used to develop solutions in A3 Problem Solving, including:
These techniques can help to generate a range of options and to select the best solution.
It is critical to follow the following best practices when developing solutions in A3 Problem Solving:
Organizations can ensure that the solutions they develop are effective and sustainable by adhering to these best practises. This will help to ensure that the problem is addressed effectively and that it does not reoccur.
The final and most important step in the A3 Problem Solving methodology is solution implementation. This is the stage at which the identified and developed solutions are put into action to address the problem. This step’s goal is to ensure that the solutions are effective, efficient, and long-lasting.
The implementation process entails putting the solutions developed in the previous step into action. This could include changes to processes, procedures, and systems, as well as employee training and education. To ensure that the solutions are effective, the implementation process should be well-planned and meticulously executed.
A3 Problem Solving solutions can be implemented using a variety of techniques, including:
It is critical to follow these best practices when implementing solutions in A3 Problem Solving:
Make certain that all relevant stakeholders are involved and supportive of the solution. Have a clear implementation plan that outlines the steps, timeline, and resources required. Continuously monitor and evaluate the solution to determine its efficacy and make any necessary changes. Encourage all stakeholders to communicate and collaborate openly. Organizations can ensure that solutions are effectively implemented and problems are effectively addressed by adhering to these best practices. The ultimate goal is to find a long-term solution to the problem and improve the organization’s overall performance.
In conclusion, A3 Problem Solving is a comprehensive and structured methodology for problem-solving that can be applied in various industries and organisations. The A3 Problem Solving process’s five steps – Define the Problem, Gather Data, Identify Root Causes, Develop Solutions, and Implement Solutions – provide a road map for effectively addressing problems and making long-term improvements.
Organizations can improve their problem-solving skills and achieve better results by following the key principles, techniques, and best practices outlined in this guide. As a result, both the organisation and its stakeholders will benefit from increased efficiency, effectiveness, and satisfaction. So, whether you’re an experienced problem solver or just getting started, consider incorporating the A3 Problem Solving methodology into your work and start reaping the benefits right away.

You might associate problem-solving with the math exercises that a seven-year-old would do at school. But problem-solving isn’t just about math — it’s a crucial skill that helps everyone make better decisions in everyday life or work.
Problem-solving involves finding effective solutions to address complex challenges, in any context they may arise.
Unfortunately, structured and systematic problem-solving methods aren’t commonly taught. Instead, when solving a problem, PMs tend to rely heavily on intuition. While for simple issues this might work well, solving a complex problem with a straightforward solution is often ineffective and can even create more problems.
In this article, you’ll learn a framework for approaching problem-solving, alongside how you can improve your problem-solving skills.
When it comes to problem-solving there are seven key steps that you should follow: define the problem, disaggregate, prioritize problem branches, create an analysis plan, conduct analysis, synthesis, and communication.
Problem-solving begins with a clear understanding of the issue at hand. Without a well-defined problem statement, confusion and misunderstandings can hinder progress. It’s crucial to ensure that the problem statement is outcome-focused, specific, measurable whenever possible, and time-bound.
Additionally, aligning the problem definition with relevant stakeholders and decision-makers is essential to ensure efforts are directed towards addressing the actual problem rather than side issues.
Complex issues often require deeper analysis. Instead of tackling the entire problem at once, the next step is to break it down into smaller, more manageable components.
Various types of logic trees (also known as issue trees or decision trees) can be used to break down the problem. At each stage where new branches are created, it’s important for them to be “MECE” – mutually exclusive and collectively exhaustive. This process of breaking down continues until manageable components are identified, allowing for individual examination.
The decomposition of the problem demands looking at the problem from various perspectives. That is why collaboration within a team often yields more valuable results, as diverse viewpoints lead to a richer pool of ideas and solutions.
The next step involves prioritization. Not all branches of the problem tree have the same impact, so it’s important to understand the significance of each and focus attention on the most impactful areas. Prioritizing helps streamline efforts and minimize the time required to solve the problem.
For prioritized components, you may need to conduct in-depth analysis. Before proceeding, a work plan is created for data gathering and analysis. If work is conducted within a team, having a plan provides guidance on what needs to be achieved, who is responsible for which tasks, and the timelines involved.
Data gathering and analysis are central to the problem-solving process. It’s a good practice to set time limits for this phase to prevent excessive time spent on perfecting details. You can employ heuristics and rule-of-thumb reasoning to improve efficiency and direct efforts towards the most impactful work.
After each individual branch component has been researched, the problem isn’t solved yet. The next step is synthesizing the data logically to address the initial question. The synthesis process and the logical relationship between the individual branch results depend on the logic tree used.
The last step is communicating the story and the solution of the problem to the stakeholders and decision-makers. Clear effective communication is necessary to build trust in the solution and facilitates understanding among all parties involved. It ensures that stakeholders grasp the intricacies of the problem and the proposed solution, leading to informed decision-making.
While problem-solving has traditionally been associated with fields like engineering and science, today it has become a fundamental skill for individuals across all professions. In fact, problem-solving consistently ranks as one of the top skills required by employers.
Problem-solving techniques can be applied in diverse contexts:
Despite the variation in domains and contexts, the fundamental approach to solving these questions remains the same. It starts with gaining a clear understanding of the problem, followed by decomposition, conducting analysis of the decomposed branches, and synthesizing it into a result that answers the initial problem.
Let’s now explore some examples where we can apply the problem solving framework.
Problem: In the production of electronic devices, you observe an increasing number of defects. How can you reduce the error rate and improve the quality?
Before delving into analysis, you can deprioritize branches that you already have information for or ones you deem less important. For instance, while transportation delays may occur, the resulting material degradation is likely negligible. For other branches, additional research and data gathering may be necessary.
Once results are obtained, synthesis is crucial to address the core question: How can you decrease the defect rate?
While all factors listed may play a role, their significance varies. Your task is to prioritize effectively. Through data analysis, you may discover that altering the equipment would bring the most substantial positive outcome. However, executing a solution isn’t always straightforward. In prioritizing, you should consider both the potential impact and the level of effort needed for implementation.
By evaluating impact and effort, you can systematically prioritize areas for improvement, focusing on those with high impact and requiring minimal effort to address. This approach ensures efficient allocation of resources towards improvements that offer the greatest return on investment.
Problem : What should be my next job role?
When breaking down this problem, you need to consider various factors that are important for your future happiness in the role. This includes aspects like the company culture, our interest in the work itself, and the lifestyle that you can afford with the role.
However, not all factors carry the same weight for us. To make sense of the results, we can assign a weight factor to each branch. For instance, passion for the job role may have a weight factor of 1, while interest in the industry may have a weight factor of 0.5, because that is less important for you.
By applying these weights to a specific role and summing the values, you can have an estimate of how suitable that role is for you. Moreover, you can compare two roles and make an informed decision based on these weighted indicators.
This framework provides the foundation and guidance needed to effectively solve problems. However, successfully applying this framework requires the following:
Problem-solving requires practice and a certain mindset. The more you practice, the easier it becomes. Here are some strategies to enhance your skills:
Problem-solving extends far beyond mathematics or scientific fields; it’s a critical skill for making informed decisions in every area of life and work. The seven-step framework presented here provides a systematic approach to problem-solving, relevant across various domains.

The term model is used to mean a teaching episode done by an experienced teacher in which a highly focussed teaching behaviour is demonstrated, in it an individual demonstrating particular patterns which the trainee learns through imitation. It is a way to talk and think about instruction in which certain facts may be organized, classified and interpreted.
Bruce Joyce and Marsha Weil describe a Model of Teaching as a plan or pattern that can be used to shape curricula, to design instructional materials and to guide instruction in the classroom and other settings.
Thus teaching models are just instructional designs. They describe the process and producing particular environmental situations which cause the student to interact in such a way that specific change occurs in his behaviour.
.According to N.K.Jangira and Azit Singh (1983): “A model of teaching is a set of inter-related components arranged in a sequence which provides guidelines to realize specific goal. It helps in designing instructional activities and environmental facilities, carrying out of these activities and realization of the stipulated objectives.”
Models of Teaching are designed for specific purposes-the teaching of information concepts, ways of thinking, the study of social values and so on-by asking students to engage in particular cognitive and social tasks. Some models centre on delivery by the instructor while others develop as the learners respond to tasks and the student is regarded as a partner in the educational enterprise.
These are based on the following specifications:
a-Specification of Environment- It specifies in definite terms the environmental conditions under which a student’s response should be observed.
b- Specification of operation - It specifies the mechanism that provides for the reaction of students and interaction with the environment.
c- Specification of criterion of Performance -It specify the criterion of Performance which is accepted by the students The behavioural outcome which the learner would demonstrate after completing specific instructional sequences are delineated in the teaching models
d- Specification of learning outcome - It specifies what the student will perform after completing an instructional sequence.
Effects of teaching by modelling
Models of Teaching are really models of learning. As we helps students acquire information ideas skills, values, ways of thinking, and means of expressing themselves, we are also teaching them how to learn . ln fact the most important long term outcome of instruction may be the students ‘increased capabilities to learn more easily and effectively in the future ,both because of the knowledge and skills they have acquired and because they have mastered learning processes.
According to Joyce and Weil, Each model results in two types of effects Instructional and Nurturant.
A- Instructional effects are the direct effects of the model which result from
the content and skills on which the activities are based.
B- Nurturant effects are those which are implicit in the learning environment.
They are the indirect effects of the model.
Bandura and Walters have formulated three kind of effect in teaching by modelling:
1- Modelling effect- The learner acquires new kind of response pattern.
2- -Inhibitory and disinhibitory effect- The learner increases or decreases the frequent, latency or intensity or previously required responses.
3- Eliciting effect- The learner receives from a model merely a cue for realising a response.
Modelling effect can be seen when a teacher demonstrates to a student how to hold a pencil or write capital A and thus shows a new behaviour. Through modelling the teacher lets the student know that it is not permissible of obscene nature in art book. The eliciting effect takes place when through modelling; a teacher tries to teach students to get up when he enters the room. Thus it provide a cue eliciting a response neither new nor inhibited. Gagne feels that learning through imitation seems to be more appropriate for tasks which are a little cognitive in nature.
Utility of Teaching Models in Teaching
Characteristics of a Teaching model
1- Encourage Art of Teaching - Teaching is considered as an art.. Teaching models encourages this art by providing learning environment.
2- Development of Inherent Abilities -Teaching models bring about the qualitative development of personality as it helps in developing human abilities. It also increases the teacher’s social competency.
3- Based on Individual Differences - Teaching model uses the student’s interest, as it is constructed on the basis of individual differences.
4- Influenced by Philosophy- Every teaching model is influenced by the philosophy of education. Hence, teachers formulate different models of teaching under the influence of the philosophy they believe.
5- Answers Fundamental Questions - In every teaching model answers to all the fundamental questions pertaining to the behaviour of students and teachers are included.
6- Providing Appropriate Experiences - Teaching models provides proper experiences to both teacher and student. Selecting the content and presenting it for learning before the students is the main essentiality of teaching. This difficulty is solved when a teacher presents appropriate experience before the students.
7- Maxims of Teaching - The basis of teaching model is the maxims of teaching. They are the foundation of each teaching model.
8- Practice and Concentration - The development of a teaching model is based on regular and continuous practice and concentration. The proper development of a teaching model is only possible when the assumptions are made clear by related thinking.
Fundamental Elements of a Teaching Model:
Normally majority of teaching models are based on the following six elements:
Focus is the central aspects of a teaching model. Objectives of teaching and aspects of environment generally constitute the focus of the model. Every teaching model is based on one or the other objective as its focal point. Any teaching model is developed by keeping this focal point in mind. Every teaching model differs from another in terms of its objectives. It is the nucleus of a teaching model. Every model is developed by keeping in view its focal point or objective . Every model has various phases, some particular types of competencies are developed by it.
Syntax of the model describes the model in action. Syntax includes the sequences of steps involved in the organization of the complete programmed of teaching. It is the systematic sequence of the activities in the model. Each model has a distinct flow of phases. It means the detailed description of the model in action. In it, the teaching activities and interactions between a pupil and the teacher are determined .The syntax of any teaching model means those points which produce activities focused on educational objectives at various phases. Under syntax, the teaching tactics, teaching activities and interaction between a student and the teacher are determined in such a pattern of sequence that the teaching objectives are achieved conveniently by providing desirable environmental situations.
Principles of Reaction
Principles of Reaction tell the teacher how to regard the learner and to respond to what the learner does. This element is concerned with the way a teacher should regard and aspects respond to the activities of the students. These responses should be appropriate and selective. They provide the teacher with rules of thumb by which to select model, appropriate responses to what the student does. This element is concerned with the teacher’s reaction to the students responses. In it,he comes to know that how he has to react to the responses of the students and has to see whether the learners have been actively involved in the process, or not.
The Social System
This element is concerned with the activities of pupil and the teacher and their mutualrelationships. Every teaching model has separate objectives and will have therefore separate social systems. It is related with the interactive roles and relationship between the teacher and the student, and the kinds of norms that are observed and student behaviour which is rewarded. The Social System describes the role of and relationships between the teacher and the pupils. In some models the teacher has a dominant role to play. In some the activity is centred around the pupils, and in some other models the activity is equally distributed. This element is based on the assumption that every class is a miniature society. In it also discussed the selection of motivating strategies and tectics for the students. Naturally social system occupies a central position in making the teaching impressive and successful in relation to the previously selected objectives. .
Support system
Support System describes the supporting conditions required to implement the model. ‘Support’ refers to additional requirements beyond the usual human skills, capacities and technical facilities. The support system relates to the additional requirements other than the usual human skills or capacities of the teacher and the facilities usually available in the ordinary classroom. Teacher requirements refer to special skills, special knowledge of the teacher and special audio-visual material like films, elf-instructional material, visit to special place etc.This includes books, films, laboratory kits, reference materials etc. It means the additional requirements beyond the usual human skill, capacities and technical facilities. In it, the evaluation is done by oral or written examination, whether the teaching objectives have been achieved or not. On the basis of this success or failure, clear idea is achieved regarding the effectiveness of strategies, tactics and techniques used during teaching.
Application
It is an important element of a teaching model. It means the utility or usage of the learnt material in other situations. Several types of teaching modes are available. Each model attempts to desirable the feasibility of its use in varying contexts related with goal achievements in terms of cognitive, and affective behaviour modification.
Types of Teaching Models:
Every teaching model has its specific objective. In order to achieve the objective of a teaching model, the teacher has to choose right type of model for achieving the particular objective. The teaching models have been classified into three main types:
1. Philosophical teaching models : Israel Saffer had mentioned such types of models. These include
A- The Insight model (Plato).- The insight model discard the assumption that the meaning of of a teaching model is merely deliver the knowledge or ideas through teaching to the mental domain of the students. According to this model the knowledge can not be provided merely through the expression of sence organs, but the knowlnd principles of language are most important.edge of the content is also a necessity. The knowledge can not be provided merely by speaking the words or listening them. Mental processes and language both work together.
B- The Impression model of teaching (John Locke).- It is based on a general assumption the the child’s brain is like a clean slate at the time of birth. Whatever experiences are provided through teaching, creates impression on child’s brain. These impressions are termed as learning. In the learning process the sense organs .
C- The Rule model ( Kant)- In this model much importance is given to the logic. Kant gives importance to logic, because in it following certain rules is essential. The objective of rule model is to devlop the logical reasoning capacities of the student. Some particular rules are followed. Planning, organisation and interaction of teaching is performed under specific rules.
2- Psychological model of teaching: John P. Dececco had mentioned such types of models. It includes
A- Basic Teaching model (Robert Glaser)- Robert Glaser (1962) has developed a stripped-down teaching model which, with modifications, is the basic teaching model. The basic teaching model divides the teaching process into four components or parts. It will be useful in several ways.. The four parts of the model represent the basic divisions. Instructional objectives, Entering behavior, instructional procedure, and finally performance assessment.
B- An Interaction model of teaching (N.A. Flander).- Flander considered teaching process as an interaction process. He divided class-room behaviour in ten categories known as Flander’s ten category system. In this model the behaviour of student and teacher is analysed. An interaction between a teacher and the student is more emphasised in this model.
C-Computer based teaching model ( Daniel Davis )- It is the most complicated model having , entering behaviour, determination of objectives and teaching aspect as fundamental elements. In this element computer teaching plan is selected according to the entering behaviour and instructional objectives. The performances of the student are evaluated. Accordingly alternative teaching plan is presented. In this model, the diagnosis and teaching go side by side. Remedial teaching is provided on the basis of diagnosis .Individual differences are also given importance.
3- Modern teaching models (Joyce and Weil)
Eggen, Kauchar and Harder (1979 ) have discussed six Information Processing Models –
Modern teaching models
The most comprehensive review of teaching models is that of Joyce and Weil (1980). Bruce R.Joyce has divided all the teaching models under the title “Modern teaching models”. They identified 23 models which are classified into four basic families based on the nature, distinctive characteristics and effects of the models. These four families are :
1. information Processing Models
2. Personal Models
3. Social Interaction Models and
4. Behaviour Modification Models.
Within the families, there are specific models which are designed to serve particular purposes.
Information Processing Models
The models of this type are concerned with the intellectual development of the individual and help to develop the method of processing information from the environment. These models focus on intellectual capacity. They are concerned with the ability of the learner to observe, organise data, understand information, form concepts, employ verbal and nonverbal symbols and solve problems. The primary purposes are :
1. The mastery of methods of inquiry
2. The mastery of academic concepts and facts
3 . The development of general intellectual skills such as the ability to reason and think more logically
The models which belong to this family are :
a. The Concept Attainment Model
b. Inquiry Training Model
c. The Advance Organiser Model
d. Cognitive Growth Development Model
e. Biological Science Inquiry Model

II. Personal Models
Personal development models assist the individual in the development of selfhood, they focus on the emotional life an individual,.
The emphasis of these models is on developing an individual into an integrated, confident and competent personality. They attempt to help students understand themselves and their goals, and to develop the means for educating themselves. Many of the personal models of teaching have been developed by counsellors, therapists and other persons interested in stimulating individual’s creativity and self expression.
The primary goals are :
a. Non-Directive Teaching Model,
b. Synectics Teaching Model,
c. Awareness Training Model,
d. Classroom Meeting Model.

A number of instructional strategies to realise different instructional goals have been developed recently by different researchers They have transformed existing knowledge in the learning and teaching processes into ‘Models of Teaching’ which can be used by teachers in the teaching, learning process for realising different instructional objectives. There is a need to incorporate a few ‘Models of Teaching’ in the curriculum of teacher education programme at the secondary as well as elementary level so that prospective teachers attain a higher degree of ‘ability to teach’.

Among the many brain events evoked by a visual stimulus, which ones are associated specifically with conscious perception, and which merely reflect nonconscious processing? Understanding the neuronal mechanisms of consciousness is a major challenge for cognitive neuroscience. Recently, progress has been achieved by contrasting behavior and brain activation in minimally different experimental conditions, one of which leads to conscious perception whereas the other does not. This chapter reviews briefly this line of research and speculates on its theoretical interpretation. I propose to draw links between evidence accumulation models, which are highly successful in capturing elementary psychophysical decisions, and the conscious/nonconscious dichotomy. In this framework, conscious access would correspond to the crossing of a threshold in evidence accumulation within a distributed global workspace, a set of recurrently connected neurons with long axons that is able to integrate and broadcast back evidence from multiple brain processors. During nonconscious processing, evidence would be accumulated locally within specialized subcircuits, but would fail to reach the threshold needed for global ignition and, therefore, conscious reportability.

Beggar’s Method
The principle of multiplication states that “If we can perform a particular operation in ‘n’ ways and the second operation in ‘m’ ways, the two operations can be performed in m x n ways in succession”. This is applicable to a finite number of operations. A factorial can be defined as a function that multiplies a single number with each and every number preceding it. For example, 5! = 5 * 4 * 3 * 2 * 1 = 120. The concept of permutations is the arrangement of objects in a particular order. The formula for permutation is given by:
n P r = n! / [n – r]! (without repetition)
Example: Find the number of ways in which 5 prizes can be distributed among 4 boys where every boy can take one or more prizes.
The 1 st prize can be distributed to any of the 4 boys, hence it is done in 4 ways. In the same way, the second, third, fourth and fifth prizes can be given in 4 ways. Total number of ways = 4 * 4 * 4 * 4 * 4 = 4 5 = 1024 ways.
Combination refers to the selection of objects without repetition where the order doesn’t matter. The formula for the combination of n things being chosen out of r is given by:
n C r = [n!] / [n – r]! r!
It is based on the distribution of like objects. It states that “The number of ways of distributing ‘n’ identical things among ‘p’ persons without any restriction (none, 1, 2 or all or any of the number of things can be given to one person)” = n+p-1 C p-1.
Number of Things That Can Be Given | Number of Things Actually Given | |
---|---|---|
P | 0, 1, 2, 3 ……. n | r |
P | 0, 1, 2, 3 ……. n | r |
P | 0, 1, 2, 3 ……. n | r |
r 1 + r 2 + …… + r p = n
The coefficient of x n in (1 + x + …… + x n ) p
= [(1 – x n+1 ) / (1 – x)] p
= (1 – x n+1 ) p (1 – x) p
The coefficient of x n in (1 – x) -p
= p+n-1 C n
= n+p-1 C p-1
Illustration 1: In how many ways can 3 rings be worn on 4 fingers if any number of rings can be worn on any finger?
(i) Rings are distinct
(ii) Rings are identical
Let R 1 , R 2 and R 3 be the rings.
Number of ways = 4 3
Here, n = 3, p = 4
Using the formula from the Beggar’s method, n+p-1 C p-1 = 3+4-1 C 4-1
Illustration 2: Find the number of ways of distributing 10 apples, 5 mangoes, and 4 oranges among 4 persons if each can receive any number of fruits and the same type of fruits is identical.
Here, p = 4
Using the formula from the Beggar’s method, n+p-1 C p-1
= [ 10+4-1 C 4-1 ] (apples) [ 5+4-1 C 4-1 ] (mangoes) [ 4+4-1 C 4-1 ] (oranges)
= 13 C 3 8 C 3 7 C 3
Illustration 3: Find the number of ways in which 16 identical toys are distributed among 3 students such that each receives not less than 3 toys.
Let the students be S 1 , S 2 , and S 3 such that each receives not less than 3 toys.
S 1 + S 2 + S 3 = 16 —- (1)
Distribute 3 toys to each of the students in the beginning.
So, equation (1) now becomes S 1 ’ + S 2 ’ + S 3 ’ = 16 – 9 = 7
= 7+3-1 C 3-1
When do we use the beggar’s method.
The Beggar’s Method is used for the distribution of like objects.
The number of ways of distributing ‘n’ identical things among ‘p’ persons without any restriction = n+p-1 C p-1 .
Combination denotes the selection of objects without repetition where the order does not matter.
The combination formula is n C r = n!/r!(n-r)!.

Downloaded on: June 21, 2024
• April 30, 2024
Variability of demand, quality management, equipment maintenance, and integration of new technologies : problems are frequent and inevitable, and manufacturers face challenges very often. Acknowledging this reality enables teams to remain vigilant, quickly identify and resolve these difficulties, and constantly improve processes and products alike.
Why focus on problem-solving? In the Lean philosophy , a problem isn't just a problem; it's also, and above all, an opportunity to do better. Rather than hiding or ignoring what's not working, the idea is to face up to it, to find structured methods for optimizing efficiency and quality. For this, there are a number of possible solutions and tools available.
What are the different stages of problem-solving? Which methods and tools are most effective in production environments? And how do you use them?
This article provides all the answers and problem-solving tips.

To better understand each of these steps, let's take the example of a factory manufacturing automotive components, faced with a sudden rise in the number of defective parts.
The first step is to recognize that a problem exists. This involves observing the symptoms and identifying the gaps between the current state and the desired goal.
The QQOQCCP tool enables you to identify the problem by collecting factual information on incidents.
After identification, you need to precisely define the problem. This involves determining its scope (using the Four A’s method, for example), representing it clearly, and understanding its impact on operations.
This step aims to analyze the factors contributing to the problem in order to identify its root cause. This is a critical process requiring in-depth examination to avoid treating symptoms alone.
Once the root cause has been identified, it's time to focus on finding solutions. This phase encourages creative problem-solving and innovation from the whole team. They have to explore existing ideas and generate new ones.
Before implementing a solution on a large scale, it is essential to test it in a controlled environment. This enables you to assess its effectiveness in real-life situations and adjust the action plan.
Once you’ve found the best solution, it must be standardized and integrated into the organization's procedures. Documenting the process helps prevent the problem from recurring and facilitates employee training .
1. 8d (eight disciplines problem solving).
8D is a quality approach to solving complex problems requiring in-depth analysis and lasting corrective action.
The method comprises eight steps:
Use case in the manufacturing industry
Problem: Recurrent failure of a major piece of equipment, leading to costly production stoppages.
8D would enable a multi-disciplinary team to systematically identify, analyze, and eliminate the root cause of the failure while implementing sustainable corrective actions.
Also known as the Deming wheel, this systematic, iterative model comprises four stages or cycles: Plan, Do, Check, Act.
The PDCA method helps companies test changes under controlled conditions, evaluate the results, and then implement improvements progressively to optimize production and ensure consistent product quality.
Problem: Variation in the quality of the finished product, which does not always meet standards.
PDCA would address this problem by planning improvements, testing them, evaluating their effectiveness, and adjusting the production process to stabilize product quality.
This Six Sigma method is highly effective in optimizing production processes, reducing variation, and eliminating defects by focusing on data and statistical analysis.
It involves clearly defining the problem (Define), measuring (Measure), and analyzing process data to identify root causes (Analyze), then implementing improvements (Improve) and controlling processes to ensure sustainable quality gains (Control).
Problem: High scrap and rework rates on an assembly line.
DMAIC would be used to specify the problem, measure performance, analyze data to find the cause, implement improvements, and control the process to reduce defects.
This fast, effective method inspired by Lean Management, consists in identifying, analyzing and solving problems directly on the shop floor. It is particularly well suited to fast-paced production environments where immediate detection and resolution are necessary to maintain production continuity and efficiency.
Problem: Frequent safety incidents in the workplace.
QRQC would enable rapid reaction to identify and resolve the causes of such incidents immediately, thereby reducing their frequency and improving overall safety.
The Four A’s method is a structured approach that is designed to systematically address and solve problems within an organization.
It is used where problems need to be solved quickly and efficiently while ensuring that lessons learned are integrated into standard practices.
Problem: Missed delivery deadlines due to production bottlenecks.
The Four A’s method would help to quickly detect bottlenecks, analyze their causes, find and implement effective solutions, and then integrate these changes into regular operations to improve on-time delivery.
The choice of problem-solving method depends on several factors:
Now it's time for the problem-solving tools! These will help structure the process and keep it moving in the right direction.
This problem-solving technique, created by Toyota founder Sakichi Toyoda, involves repeatedly asking the question "Why?" until the root cause of a given problem is revealed. It's a simple but powerful tool for finding root causes.
A factory has a problem with late delivery of finished products:
Also known as the "fishbone diagram" or "5M", this tool developed by Kaoru Ishikawa helps to systematically visualize all the potential causes of a specific problem, as well as the contributing factors.
Causes are divided into 5 main categories.
A factory encounters a problem with a drop in product quality:
This evolution of the Ishikawa diagram focuses on not five, but seven major problem areas: Manpower, Method, Materials, Environment, Equipment, Management, Measurement.
A factory is experiencing machine failure problems:
The Pareto or 80/20 principle is very useful for focusing on the problems that will have the greatest impact once solved, and for making informed decisions.
In a factory producing electronic components, 80% of production defects stem from just 20% of the manufacturing processes.
By analyzing production data, the company could discover that the majority of defects are linked to errors in the soldering and PCB inspection stages. These two stages, although representing a small part of the total manufacturing process, are crucial and require special attention to reduce the overall number of defects.
This tool helps gather comprehensive information on a problem by answering these key questions: Who, What, Where, When, How, How much, Why. Thus, it provides an in-depth understanding of the situation.
There is a delay in production at a furniture manufacturing plant:
Other tools can also be useful for structuring problem-solving methods:
Integrate problem-solving into daily routines.
Instead of seeing problem-solving as a separate activity, integrate it into daily routines. For example, set up SIM meetings to discuss ongoing problems as a group and monitor progress on solutions.
Adopt a Daily Management System (DMS) like UTrakk to quickly identify problems, track corrective actions, facilitate collaboration between teams, and document solutions in a centralized repository.
Define Lean KPIs that measure the effectiveness of the problem-solving process (average time to solve the problem, problem recurrence rate, and impact of solutions on business performance).
To understand problems, you need to go where value is created. Encourage managers to go on the shop floor to directly observe processes, interact with operators, and identify possible improvements.
Form teams with members from different departments to tackle complex problem-solving. Integrating different angles, perspectives, and expertise broadens the point of view on the subject, enriches the analysis, and generates more creative ideas.
In addition to basic training, use mentoring and coaching to develop problem-solving skills . Experienced employees can guide less experienced ones, sharing their know-how.
When a problem is solved, conduct a post-mortem to discuss what went well, what didn't, and how processes can be improved.
Tracking and evaluating each solution implemented allows you to adjust strategies as needed, learn from past experiences, and foster continuous improvement .
Using organized methods and analytical tools to tackle challenges is essential for manufacturers seeking to improve operational efficiency and product quality. UTrakk DMS is the perfect solution for this structured approach to daily problem-solving. With its multiple functionalities – rituals, actions, dashboards, and more – this Daily Management System can adapt to any problem-solving method to optimize every step of the process. Once a solution is standardized, it can be documented in UTrakk’s Knowledge Center to ensure compliance and prevent recurrence.
Adopting these problem-solving techniques not only enables manufacturers to respond effectively to today's challenges, but it also lays the foundations for continuous improvement, ensuring their competitiveness in an ever-changing industrial environment .
What are the key problem-solving methods for manufacturers.
The key problem-solving methods for manufacturers include Lean manufacturing, Six Sigma, and the PDCA (Plan-Do-Check-Act) cycle. These methodologies focus on eliminating waste, optimizing processes, and implementing continuous improvement to enhance operational efficiency.
Manufacturers can effectively implement Lean principles by identifying and eliminating waste, optimizing workflows, and improving overall efficiency through techniques like Kanban and 5S. Training employees and involving them in the continuous improvement process are also critical steps.
Six Sigma is important in manufacturing because it provides a data-driven approach for reducing defects and variability in processes. This methodology helps in improving product quality and operational efficiency by following the DMAIC (Define-Measure-Analyze-Improve-Control) framework.
Technology plays a crucial role in enhancing problem-solving in manufacturing. Digital twins, augmented reality, and collaborative robotics are technologies that help improve precision, efficiency, and safety, facilitating better decision-making and process optimization.
Continuous improvement practices offer several benefits, including increased operational efficiency, reduced waste and costs, and improved employee engagement and customer satisfaction. These practices encourage a proactive approach to addressing inefficiencies and fostering innovation.
