Developing 2nd Why Requirements for Effective Problem Solving

Learn to identify and investigate root causes effectively with the 2nd Why method, using examples and logical approaches. Explore various sequence options like valve manufacturing or process flow like cooking to refine requirements for better outcomes. Use FMEA and Cause & Effect analysis for comprehensive problem-solving.

  1. The2nd Why can be formed once the Team has Completed the 1st Why 2nd Why / Requirements Development 2nd Why / Requirements Cause & Effect (Fishbone) 2nd Why / Requirements FMEA 2nd Why / Requirements Examples

  2. 2nd Why / Requirements Development D4 - Developing the 2nd Why / Requirements …Options The2nd Why defines the Requirements of the 1stWhy/ Functions Option 1:Use the Process Sequence Example ‘VALVE MANUFACTURING’ Option 2: Use the Product (Assembly) Components, Example ‘VALVE LEAKS’ TEST/ ASSEMBLY WASHER VALVE BODY ADAPTOR FLUID & FITMENT Option 3: Use a Circumstantial approach, Example ‘TEAM DISAGREEMENT’ NERVES ASSOCIATED ORGANS POSTURE SPINAL COLUMN MUSCLES DESIGN/ APPLICATION ASSEMBLY/ TEST RAW MATERIAL MACHINING TAPPING Option 4: Use a Process Orientated (Process Flow ) approach, Example ‘COOKING’ INCONSIDERATION SERVE FOOD COMMUNICATION BUY INGREDIENTS PREPARE INGREDIENTS DEADLINES COOK/BAKE FOOD FRUSTRATION PERSONALITY EAT FOOD Option 5: Use any other logical method or sequence, Example ‘BACK ACHES’

  3. 2nd Why / Requirements Examples D4 - Developing the 2nd Why / Requirements …Options The2nd Why defines the Requirements of the 1stWhy / Functions Option 1:Use the Process Sequence Example ‘VALVE MANUFACTURING’ With additional pop-up aid RAW MATERIAL DESIGN/ APPLICATION MACHINING TAPPING ASSEMBLY/ TEST

  4. 2nd Why / Requirements FMEA D4 – 2nd Why = the Requirements Will automaticallybe updated 2nd Why / Requirements • Select which Requirement you would like toFurther Investigate RAW MATERIAL MACHINING TAPPING ASSEMBLY/ TEST DESIGN/ APPLICATION VALVE BODY ADAPTOR CUTTING FLUID SETTINGS 3rd Why 3rd Why 3rd Why 4th Why 4th Why 5th Why

  5. 2nd Why / Requirements C&E (Fishbone) D4 - The 2nd Why will be forwarded to the 2nd Arm/s of the Cause & Effect Diagram RAW MATERIAL DESIGN/ APPLICATION MACHINING TAPPING ASSEMBLY/ TEST

  6. Now start the D4 3rd Why This completes the D4 2nd Why
