Applied A3 Thinking Technique
The A3 thinking technique in lean manufacturing is a problem-solving method outlined in simply structured sections. It takes its name from its application on A3 paper of 420 x 297 mm. A general A3 report consists of the following model: 1) History, 2) Current Situation and Problem, 3) Purpose, 4) Root Cause Analysis, 5) Recommendations and Plan, 6) Control of Results and Follow-up 7) Next Problem. The report is used to standardize and simplify the solution found. The content follows the logic of the Plan-Apply-Check-Prevent (PUKO) cycle.
In our Plant Design and Planning course with Assist. Prof. Dr. Onur DOĞAN, we have actively developed solutions to the problems identified by our students using the A3 thinking technique in groups.
