This document discusses the A3 problem solving approach and provides examples of different types of A3 reports. The A3 approach uses a logical, evidence-based process based on the PDCA cycle to drive continuous improvement. It emphasizes brevity, objectivity, and visualization. Different types of A3 reports are used for problem solving, proposals, and status updates. Problem solving reports focus on root cause analysis, proposals on planning, and status reports on results and follow up actions.
