  • Also known as A3 Problem Solving.

    Variants include 8D and CAPA.

    A significant part of a leader’s role involves addressing problems as they arise. Various approaches and tools are available to facilitate problem-solvingwhich is the driving force behind continuous improvement. These methods range from the advanced and more complex methodologies like Six Sigma to the simpler and more straightforward A3 thinking approach.

    The power of the A3 approach lies in its systematic and structured approach to problem-solving. Although it appears to be a step-by-step process, A3 is built around the PDCA philosophy. It relies on the principle that it is much better to address the real root-cause rather than trying to find a solution. Hence, it’s important not to jump to the solution when solving a problem as it is likely to be less effective.

    A3 thinking provides an effective way to bring together many of the problem-solving tools into one place. For example, techniques such as the 5 Whys and fishbone analysis can be used during the ‘Analysis’ stage to help identifying the root causes. Additionally, visual aids and graphs are highly recommended in the A3 report, as they are more effective than text in communicating ideas and providing concise project updates.

    A3 thinking involves the practice of consolidating the problem, analysis, countermeasures, and action plan onto a single sheet of paper, commonly an A3-sized sheet. This brief document serves as a summary of the project at hand and is regarded as a valuable storytelling tool for project communication. Utilizing the A3 approach doesn’t require any specialized software or advanced computer skills. You may however use readily available A3 templates, or rely on basic tools such as paper, pencil and an eraser as you will need to erase and rewrite several times.

    One of the characteristics of the A3 approach is that it does not get into specific details. Detailed documents are usually attached to the A3 report to prevent overwhelming the reader with an excess of information.

    The A3 process is typically structured in multiple stages based on the PDCA model. The primary focus is on developing understanding of the current situation and defining the desired outcome before thinking about the solution. While the exact number of stages may vary depending on the preference of the company, what truly matters is adhering to a structured approach to problem-solving.

    A3 Seven Stages Model

    An A3 process is often managed by an individual who should own and maintain the A3 report. This individual takes the lead in steering the process, facilitating team involvement, and preparing the A3 report with team input. One of the most common models for A3 thinking is the seven stages model which is described in the following.

    1. Background – The first step is to identify the business reason for choosing this problem or opportunity. In this stage, you need to identify the gap in performance and the extent of the problem.

    2. Current situation – The purpose of this stage is to document the current state of the problem. You may need to refer to the process map or go to the Gemba to truly understand the current situation.

    3. Target – The purpose of this stage is to define the desired future state. Clearly identify the expected benefits from solving the problem, the scope, and the key metrics that will help measure the success of the project.

    4. Analysis – The objective of this stage is to conduct an in-depth analysis of the problem and understand why it’s happening. It might involve tools like the 5 Whys and cause-and-effect analysis, as well as advanced statistical methods.

    5. Countermeasures – Countermeasures are theactions to be taken to eliminate root causes or reduce their effects. The team should brainstorm and evaluate possible countermeasures based on the analysis conducted earlier.

    6. Implementation Plan – To achieve the target, develop a workable plan to implement the countermeasures. Gantt charts are great ways to manage implementation plans very simply and easily. Once the action plan is finalized, the team should begin working on the activities needed to implement the countermeasures.

    7. Follow-up – The final stage involves evaluating the implementation of the plan and the results achieved. Follow-up actions are important to ensure the benefits extend beyond the project’s completion.

    Wrapping Up

    A3 thinking represents a logical and structured approach for problem solving and continuous improvement. This approach can be used for most kinds of problems and in any part of the business. Originating from the Toyota Production System (TPS), it has been adopted by many Lean organizations around the world.

    A3 thinking not only provides a systematic approach for problem-solving. The development of a continuous improvement culture is at the core of A3 thinking. It has become one of the most popular Lean tools today where people and teams work together to solve problems, share results and learn from each other.
