The Brainstormed Data Base of Potential Causes can be sorted or re-arranged into Logical Independent Groups 1 st Why Concept Appropriate Names can be given to Groups of Potential Causes which naturally belong to each other. PSI 365 promotes the use of Sorting the Potential Causes into - Five - Groups. The Group Names can, as applicable to the nature of the Problem, be achieved in several ways. Names can be taken.. from the Process Flow, correlating to the FMEA. from the traditional 5M. if an Assembly . could be taken from the Assembly Components. or can be taken from any combination or derivative which effectively identifies . Groups of Potential Causes .. for further analysis. 1 st Why One 1 st Why Two 1 st Why Three 1 st Why Four 1 st Why Five

1st Why; FMEA & Cause & Effect Groups are automatically Correlated to the FMEA & The Cause & Effect Diagram RAW MATERIAL MACHINING TAPPING ASSEMBLY/TESTDESIGN/APPLICATION The 1 st Whys Groups relate to the Process Steps of the Process Flow Chart and the Functions of the FMEA. In some situations the Design of the Product may also have a specific influence over the Manufacturability The Skeleton of a Cause & Effect Diagram will now be available

Slide 6

The Affinity Diagram begins to be built with the Potential Causes determined during the Comparative (Is/Is Not) Analysis. Building the Affinity Diagram The Team may be of the opinion that a particular 1 st Why is likely to host the Root Cause. The Team may be correct, however looking at the Brainstormed Potential Causes may uncover other Potential Causes.

Continue to build the Groups by Copying the applicable Potential Causes from one group to another or by Typing directly into the Group. Logical Distribution of 5M Database
