Center for Reliability Growth
The Center for Reliability Growth (CRG) enables programs to field faster with less risk of program delays. The CRG offers a menu of options for programs:
- Lower-Level Testing - The CRG provides methodology and models to maximize the use of lower-level testing results to feed programmatic and design decisions.
- Modeling and Simulation - Modeling and Simulation (M&S) is one of the least expensive ways to accelerate fielding and reduce risks. Finite element modeling, Dynamics modeling, Thermal modeling, etc. provide a mature suite of capabilities that are often underutilized as part of government and contractor efforts.
- Scorecards and Engineering Reviews – The CRG has scorecards that can identify early opportunities for correcting the GOTCHAs that may be hidden è saving time and money.
- Leveraging All Data Sources – The CRG uses Bayesian-based and other approaches to maximize the information gained from shorter experimentation or testing durations, enabling program acceleration and increasing knowledge for decisions.
- Systems Theoretic Process Analysis (STPA) – Developed by the Massachusetts Institute of Technology, this approach is especially powerful for autonomous or complex software systems. Failures often occur not from broken parts, but from unexpected issues between parts, logic, or people and machines.
- Function-Based Reliability Assessment – This approach takes complex interactions and parameters and utilizes a framework tied to mission objectives. This approach is especially powerful for shaping and assessing requirements and for characterizing results for leadership.
The CRG maintains a collection of key reliability tools and models that are accessible at:
