Corrective Action Problem Solving John DeGiovanni Quality Leadership Forum Johnson Space Center Sept 25, 2002 Quality Director Space Shuttle Main Engine Program Boeing Canoga Park
The Purpose of Corrective Action? ? • Improving Product • Decreasing Cost • Improving Delivery • Adding Value Learning to Treat Corrective Action as a Business Case
Weighing the Factors… Considerations • Timeliness • Depth • Generic Implications • Effectiveness • Interrelationship of Causes & Effects • Consistency • Problem Solving Tool Selection NASA Code Q Suggestion to Try New Problem Solving Tool
Every Toolbox has a First Tool The Problem Solving Tool • Checklist-oriented • Developed by Government and Industry • System / Process Structured 22 Categories Failure Codes Possibilities
The Problem Solving Tool Sample Page
Application & Evaluation Application • Problem Solving Tool Applied to Over 20 SSME Corrective Actions • Assessed for: • Usefulness • Accuracy • Timeliness • Integration Ability • Direction
Easy to Use Time Saving/Efficient Covers Wide Array of Process Failures & Causes “Human Performance Factors “Systemic” Contributors Structure Identifies Factors Not Previously Considered Easy to Categorize Factors Structured Approach Consistent Programmable/Accessible System Approach Adaptable as a Comprehensive Audit Tool Initial Selection of Categories Adaptive Reasoning Can Require Tailoring Checklist Culture Paper-based / Cumbersome Pro and Cons Pros Cons
Enhancing Implementation • Adopted Tool for Web Access • Accessibility • User Friendly, On-line • Edited Text • Added Document Reference • Ref. to NC, UCR, PR, etc • Trending Availability • Paperless
The Corrective Action Toolbox Status • Several Tools being Incorporated Into our CA Toolbox • Different Tools for Different Applications • Consortium Checklist • Cause Chains • Reason & Other Software Tools • Apollo Methodology • i.e., “One Tool Does Not Fit All” Developing Our Corrective Action Toolbox
Cause Chain Value Line “The Theory” Cause Chain Designed To: Value Form Team Facts Root Cause Value Immediate Cause Relationship Action Plan Tasks
Cause Chain 101 Analysis “Value Line Biorhythm” Trouble Signs: 3 cause chain meetings Protests on cause Refuse to attend Push to a CAB deadline Problem weeks old - no action Value “Value” Changes Over Time, Given Certain Events
Environment Hardware “Product” Software “Tools” Liveware “People” Corrective Action Factors • Outcomes depend on: • Mindsets • Priorities • Values • Knowledge • Issues Environment is Critical… Interrelationships Create the Corrective Action Results
What Is Necessary for Better CA? Excellent C&CA effort Existing undesirable effects requiring C&CA effort Team wants to do it Team understands what to do Team is capable of doing it Team knows how to do it No obstacles interfere • Priorities • Schedule • Budget • Mind sets Tools Environment C & CA Network Logic Diagram
How Should the Tool Help? • Criteria that Influences the Tool Selection • Ease of Use • Interactions Among Causes • Probability of First Time Through (F.T.T.) Success • Business Case for Intervention • Immediate Applicability • Accessibility • Software Compatibility • CA Effectiveness Measures • Supplier Usefulness
More Complex Cases Medium Complexity Cases Fairly Simple Cases Does One Size Fit All? Events Existing Tools • MORT • Human Factors MORT • S.O.U.R.C.E • Seeking Out the Underlying Root Causes • Fault Tree Analysis • Logic Tree Analysis • Apollo • Reason • IAT-M • Incident Analysis Tool - Modified • Cause Chain • 5 Why’s • Fishbone Diagram
Understanding and The Capability of People • What We Are Doing? • Studying the C&CA Network Logic • Reviewing Tools • Assessing Structure • Investigating Training Options • ENVIRONMENT Changes (From Apollo Root Cause Analysis) “ Only 2 or 3 out of 10 People Can Apply the Logic Effectively”
Group Interaction (Exercise) Possible Environment Modifying Actions Environment Challenges Real “People” Build Hardware (They Don’t Do C&CA) Fault-finding More Habitual Than Fact-finding C&CA Perceived As a “Nice-to-have” vs “Must Have”
Moving Out • How Are We Proceeding? • Mentoring/Facilitation Mode • Expanding our Tools • Raising Visibility of System Performance • Trends • Timeliness / Status • Accountability Shifting • CABs: Review Mode Action Mode • Investigating Restructuring of Relationships Developing a Plan to Address The Environment
