Templates  

This Template Provides the Following Worksheets:

1. 1

   Boundary Diagram: use to determine system scope.
2. 2

   System Analysis: perform system analysis. For robust design, focus on the “ideal function", i.e., add the most important functional requirements appearing on the p-diagram.
3. 3

   P-Diagram: parameter diagram of noise factors, signal factors, and control factors versus functional requirements (CTQs, “Ideal Function”).
4. 4

   Component Design Matrix: Cause-Effect Matrix of design and noise factors versus key CTQs (“Ideal Function”). Document knowledge on cause effect relations in this matrix and update whenever new information is received. Use this matrix for planning optimization activities such as design of experiments (DOE).
5. 5

   Robustness Checklist: matrix of noise factors versus design controls (design verification methods) from the design verification plan (DVP). Use to verify coverage of noise factors by DVP.

What to Add or Combine:

• Fault Tree Analysis: formal fault tree analysis with probabilities. Use to document fault networks and determine probabilities of events.
• Causal Loop Analysis: Add Causal Loop Analysis for detailed understanding of cause-effect relationships between system components.
