Preliminary design risk review PDRR

General: PDRRs are conducted for each item or component in the product configuration under development. For instance, a team member may have discovered a new resistor concept in the Wiki (Internet search for new concepts) process and incorporated the design into the product. But the new resistor turns out to be more expensive than the budgeted resistor for this product, and has not been tested under the appropriate user conditions of this product. PDRRs are normally conducted during the detailed design stage of product development, after a design approach has been formulated to uncover risks. More reviews may be scheduled to address follow-up and unanticipated test results.

Review Items: Here are some of the targets for review:

A. Schedule; is the project on schedule?

B. Design requirement synthesis

1. Interface requirements; are all component interfaces OK?

2. Performance requirements; does the product/component perform to requirements?

3. Applicable design standards; what are the design requirements?

4. Configuration and document numbering; are all components documented in the configuration management software and appropriately numbered?

5. Standardization; are there standardization opportunities?

6. Design trade studies; what will be the product cost and financial impacts?

7. Design to cost goals; is the product within design and production costs?

8. Design for growth capabilities; can the product be enhanced later?

9. Layout drawings and preliminary drawings; are all design documents in proper order?

C. Environmental requirements

1. Similarity assessment

2. Proposed verification plan; is there a plan to verify performance?

D. Producibility and manufacturing

1. Preliminary manufacturing process; can the product be manufactured?

2. Design concepts that require advancement of current capabilities; will current performance meet all concept requirements?

3. Identification of tooling requirements; will manufacturing tooling be impacted?

E. Testability requirements

1. Preliminary production test procedure; is the production test protocol prepared?

2. Specific subassembly requirements to support production test; are there test articles available?

F. Reliability/maintainability/availability (R/M/A) requirements

1. Reliability issues with similar designs; have there been reliability results that are relevant to this product?

2. Preliminary assessment of high-risk, long-lead items; what are the high-risk items, either from a technical or procurement standpoint?

G. Electromagnetic compatibility requirements

1. Electrical grounding scheme; if electrical systems are involved, is there adequate grounding?

2. Signal isolation scheme; are signals tested?

H. Technical risk

1. Project level cost/schedule implications; what are the high risks identified in the risk matrix?

2. Preliminary risk mitigation plan; are there contingencies for each risk— incorporated into the project schedule and resources planned?

After the Review: The review document is prepared and communicated to all project stakeholders in a company network system.
