Powerful Test Planning and Management Tools
Growth Planning Folio
RGA's growth planning folio has been redesigned for improved usability and enhanced functionality.
You still have the ability to calculate any of the variables in the reliability growth management strategy (such as the MTBF goal that’s feasible for a given management strategy, or the initial MTBF that’s needed before you start the test program), and quickly generate a graphical plot that shows how the idealized growth curves are planned to improve over each test phase.
The new interface now supports up to 10 phases and makes it easier to adjust your inputs to find the most effective reliability growth testing plan. It also adds an integrated QCP for quick access to specific estimates based on the plan.
Multi-Phase Data Sheets
While the Crow Extended model facilitates reliability growth projections, planning and analysis for a single test phase, the Crow Extended – Continuous Evaluation model is designed for analyzing data across multiple test phases. Specially designed multi-phase data sheets allow you to enter the data from all test phases into the same data sheet and use event codes to specify the end time for each phase (PH). You can also use other event codes to specify:
- The exact time when a delayed fix was implemented (I).
- Failures due to performance (P) or quality (Q) issues, which can be excluded from the analysis, if desired.
- Specific analysis points (AP) at which to calculate the MTBF/failure intensity in order to show the progress in multi-phase plots.
- Any data point you wish to exclude from the analysis (X).
The multi-phase plot displays key analysis results from data analyzed with either of the Crow Extended models so you can see how the demonstrated, projected and growth potential MTBF changes across multiple analysis points and/or test phases.
If desired, you can also link the plot to a growth planning folio so you can see how the actual test results compare to the plan, and determine if it’s necessary to make adjustments in subsequent test phases in order to meet your reliability growth goals.
