SECTION ONE - INTRODUCTION
Assessment is a broad term that includes all techniques used to determine a product design status or operational capability. Assessment can include analysis, modeling, simulation, and testing. The most significant elements are analysis and modeling, as either can be accomplished early in the design process at a much lower cost than simulation or testing. Analysis is also an effective tool in evaluating design trade-offs that will result in a better product. An analysis can estimate the impact of more cooling, extra redundancy, better components, or extreme operating conditions. The purpose of this Blueprint, Assessing Reliability Progress, is to describe a number of tasks that should be considered if a producer wishes to assess the status of inherent product design reliability before manufacturing of the product begins. Each task is presented in sufficient detail to describe to the user how to do the assessment, how to interpret the results and when the task should be performed. Examples and references are included as guides for the analyst. The discussion of each assessment technique will consider:
- Purpose (what)
- Benefit (why)
- Timing (when)
- Application guidelines (how)
