Specifying Reliability

Formulating a reliability requirement to place on a supplier is not a simple matter. Understanding and interpreting a potential supplier reliability specification can also be difficult. Reliability is usually important to a product, but it is very often badly specified in requirements. Equally it is often badly described by suppliers in data sheets or technical specifications.

This presentation is not highly technical and involves no mathematics. It aims to guide the practitioner through the process of writing and understanding well considered reliability specifications. It also points out some of the common mistakes that are made and how to avoid them. It shows the simple logical process that can be followed to define the requirement, how it is to be provided and how to verify that it has been met. Different methods of verification are considered but the presentation particularly discusses evidence-based techniques that do not require a supplier to carry out any extra work beyond their usual product programme.

Key Words: Reliability Definition, Reliability Specification, Reliability Verification
