- Step 4: Develop a target state.
- Step 5: Create an implementation plan.
When should an A3 be used?
Using a simplified version of the problem solving A3 flow, such as “four-box” problem solving template on an A4 (letter) size paper, can be of benefit when: a problem is isolated to one working group (in in the direct control of one area) the root cause isn’t obvious (isn’t a “just do it”)
