Execution Steps for Integrity Programs
Bailey, Watson & Associates
- Specify Requirements for Product Performance Within Environment Over Intended Operational LIfe
- Design & Verify (by Analysis & Test) Product Performance Within Specified Environment
- Verify That Product Quality & Producibility Standards Match Design Assumptions
- Validate Requirements for Product Performance In Operational Environment Over the Product Service Life
- Maintain Integrity by Life Management
Specify Product Performance Requirements For Environment Over Intended Operational Life
- System Level Requirements Reduced to Specified Usages and Environments Appropriate for Design Development
- Changes to System Level Requirements MUST Correspondingly Be Addressed by Changes to Specified Usages & Environments for Product Design
- Design Usage & Environments Relate to System Level Operational Parameters
- Relationship Supports Monitoring of Use & Environment During Fielded Operations of Equipment
Design & Verify by Analysis & Test (Product Performance within Specified Environment)
- Modeling, Analysis, Data Correlation to Verify Design with Margin
- Margin Associated with Anticipated Statistical Variability in Material, Use, Environment & Manufactured Quality
- Margin Must Be Sufficient to Address Tradeoffs in Production, Design Verification, Maintenance Costs, Availability & Safety Impacts
- Historical Data, Testing and Eventually Operational Experience Will Support Basis for Design Margin
Verify That Product Quality & Producibility Standards Match Design Assumptions
- Minimize Production Cost by Design for Producibility
- Producible Designs Offer Best Opportunity to Achieve Quality Objectives
- Identify Critical Design Features Requiring Statistical Process Controls and DOE Initiatives
- Controlled Features are Monitored During Operations
Validate Product Performance in Operational Environment Over the Product Service Life
- During Development: Integrated Suystems Level Testing Used to Substantiate Models & Simulations That Relate Component Usage & Environments to System Operation
- During Development: Statistical Basis Initially Identified for Measures of Failure Potential Due to Fatigue, Durability, Damage Tolerance, Corrosion and Operating Faults
- After Development: Integrity Validated Through Life Management
- After Development: Statistical Basis for Predicting Failures Updated Using Data From Operating Experience
Maintain Integrity Through Life Management
- Expect Actual Product Use & Performance To Deviate from Design Baseline Assumptions.
- Expected Fielded Envronment Will Not Be As Predicted
- Expect Production Quality Goals Will Not Be As Forecast
- Expect Unanticipated Failure & Fault Events. Anticipate Failures at Greater than Expected Frequency
- Life Management Addresses These Expectations and Furthers Design Validation by Monitoring Usage & Environments, Examining Probability for Maintenance Incidents and Determining Action to Redesign, Provide Maintenance, Control Usage or Improve Quality.

About Bailey, Watson & Associates: The founders of Bailey, Watson & Associates have been engaged with integrity programs since the mid 1980's. John Bailey & Paul Watson both recently retired from Lockheed Martin where they were engaged in implementing Integrity for multiple modern aircraft programs. Mr. J. Bailey was Senior Manager responsible for defining and implementing Integrity on a current fighter program. Mr. Watson was technical lead for Vehicle Systems Equipment Integrity and was responsible for a wide range of hydraulic, mechanical and electrical equipment in accordance with Mr. Bailey's program. Principals Bailey & Watson maintain close contact with other former Integrity counterparts. The combined experience of this team encompasses mechanical, electrical, optical and structural systems. They have wide ranging experience in environmental and usage definition, definition of Integrity Requirements, application to design, verification and field usage monitoring.
