3: Identify and confirm the underlying cause(s) of the abnormal events and conditions.
4: Identify, evaluate, and select countermeasures to the causes that will eliminate them.
Problem-solving approaches is bit challenging, but there are not so many differences between these approaches, as one could expect.
All differences are depending only on the type of problem, which has to be solved.
PDCA: The PDCA-Cycle, also called the Deming-Cycle or Shewhart-Cycle, is the classic problem-solving approach in a LEAN environment.
PDCA is used for medium sized problems and the Act-phase implies that the PDCA-Cycle should start again in the sense of a continuous improvement process.The approach establishes a permanent corrective action based on statistical analysis of the problem and focuses on the origin of the problem by determining its root causes.Although it originally comprised eight stages, or disciplines, it was later augmented by an initial planning stage, so mathmatically there are 9D's.A3: The A3-Report, developed by Toyota, is an 8-step PDCA that should fit on an A3 sheet of paper.It is a collaborative and visual tool (graphs should be included). 8D/PSP, The 8D Problem Solving Process, or 8D-Report: It is an 8-step PDCA with the focus on fast reaction to customer complaints (e.g.The most successful lean/continuous improvement (CI) coordinators and leaders have more than just the questioning skills for developmental coaching.They also know how to assess the problem-solving abilities of their coachees.The critical importance of grasping the actual conditions of problem solving situations (firsthand whenever possible) will be stressed throughout the PDCA process.Workshop activities will include: 1: Descriptions of each step in the process along with its key points, purpose, and examples of its activities’ outcomes.This is to make the 8D/PSP idiot proof:-) and to avoid wasting time to come up with your own form/format.As the 8D/PSP (Eight Disciplines of Problem Solving Process), template/documentation is already established, just complete the 8D form step by step and complete all required actions.
