DVP&R (Design Verification Plan and Report)
Product and process development activities like New Product Introduction, Advanced Product Quality Planning and Collaborative Product Process Delivery (CPPD) require some form of confirmation that the product or process being developed is moving in the correct direction. Product and process designs must be evaluated for their effectiveness at meeting customer expectations and specifications. This verification and validation process has historically been associated with testing. Design Verification Plan and Report (DVP&R) is a collection of tests and evaluation techniques to be followed that can provide confidence that the design is reliable.
DVP&R is not simply a list of tests that the engineering community or current written specifications dictate. Costs and timing for completing tests and budget constraints all drive the need for an efficient way to plan verification and validation and therefore additional consideration on how and how much testing is needed.
DVP&R Inputs:
DVP&R receives input from many sources. A few are listed below:
- Requirements and Specifications
- New Content and Quality Function Deployment (QFD)
- Design Failure Mode and Effects Analysis (DFMEA)
- Robustness Analysis
- Past History and Legacy data.
These inputs are crucial for proper planning of the test and evaluation techniques, sample sizes and timing for completion of tests.
DVP&R Planning
The proper way to look at testing and planning for verification of designs must include considerations for speed and effectiveness as well. This is a multiple step process considering many factors including:
- Past Product or Process DNA
- Leveraging of Supply Chain capability and experience
- Computer Aided Engineering (CAE) Finite Element Analysis etc...
- Component Testing or Bench Testing with Noise Factor Management
- Sub-Systems testing.
- Final product or process validation
- Legacy capture and feed-back
Each level listed above is executed in sequence which follows a low cost (fast verification) to high cost (slow verification). When coupled with statistical confidence and reliability targets, an intelligent testing plan can support good verification confidence with lower cost testing and evaluation options.
