Facilitating participation and responsibility across an entire organization, this one-of- a-kind workbook takes readers step-by-step through the disciplined development of an A3 report, a single-sided piece of paper used by Lean companies to promote efficiency. The A3 provides all employees at all levels with a method to quickly identify a problem, analyze its root cause, select appropriate countermeasures, and communicate necessary actions to decision makers. The workbook includes worksheet templates that can be reproduced and used in future problem solving efforts.
