A3 Problem Solving

What is the A3 problem-solving methodology?

The A3 is a structured problem solving and continuous improvement approach/methodology.

Used extensively by organisations implementing an Operational Excellence strategy within their business, It is based upon the principles of Deming’s PDCA cycle. (Plan-Do-Check-Act)

It can be used by large or small businesses alike and can be extremely useful for communicating business objectives or plans to all employees and stakeholders in the organisation, explaining their part in the strategy.

Who created the A3 approach? 

The A3 is a structured problem solving and continuous improvement approach which was originally developed by The Toyota Motor Co.

It is called an A3 due to the fact that this was the size of the paper originally used to draw up A3’s. It was the largest format of paper that could be communicated electronically at the time (by facsimile machine).

What’s involved?

A3 problem-solving consists of four sections or quadrants:-

  1. Business Case – provides the data and rationale for the project – Why it is being done and benefits to the organization.
  2. Current Condition – shows what the current situation looks like. Based upon facts and data, this quadrant uses various media to make the situation highly visible. These can include sketches, diagrams, data and charts.
  3. Target Condition – Shows what state we wish to reach once the project is implemented. It should communicate what tangible benefits shall be obtained upon completion of the project or eradication of the problem. Utilises sketches, diagrams, charts and data to show what the process will look like outlining projected results from the change.
  4. Plan – Shows the steps needed to reach the target condition and timescales involved – It should show due dates, timings of actions along with the names of the people who are responsible to carry such actions out. Utilizes Gantt Charts, Critical Paths, milestones etc. Records progress and outlines and align responsibilities for action.  Very often this section of the A3 is in GANNT chart format and should be dynamic. Actions should be signed off as they are completed.

In addition to the action plan, there should be a chart detailing the measures that shall be in place to determine that the target condition has been achieved and that the Action Plan can be closed.

After completion, the Project A3’s should be signed off as complete. It should be noted that an A3 may “spawn” several sub-A3’s during the life of a project or during the eradication of a problem.
