  2. Develop Complete List 1. Select Key Product Features: Screening Study Varying Machine / Material Is Feature Critical to Product Performance OR Responsive to Variation? No Omit From Key Feature Study Repeat for Each Feature Yes Designate as Key Feature To Feature Study AEP 10/21/98

  3. From Key Feature List From Process Variable Study 2.Study Key Features: Study Key Product Feature Baseline Current Operating Conditions Are Key Product Features Stable To Variable Study Repeat for Each Variable No Investigate Process Variables Yes Investigate Process Relationship To Process Relationship Study AEP 10/21/98

  4. From Unstable Feature Study 3.Select Key Process Variables: Develop Complete List Brainstorm & Fishbone Select Process Variables to Study Does Process Variable Affect Stability? No Omit From Variable Study Repeat for Each Variable Yes Designate as Key Variable Change Process Study Process Variables Are Process Variables Stable? No Define Source of Instability Yes Return to Key Feature Study AEP 10/21/98

  5. From Stable Key Features 4.Investigate Process Relationships: Conduct Designed Experiments Develop process / product “Process Window “ Key Feature Capability Study Find Centering Cause & Correct Are Key Features Capable Good Cp & Bad Cpk Yes No No Yes Can Spec. Change? Yes Change Spec. Draft Operators Guide No Establish SPC Charting Change Process Machine or Material AEP 10/21/98
