Product development processes - from deterministic to probabilistic: a Design for 6-Sigma approach to lean product validation: Part II

摘要

An important phase of any product development process is design validation. This phase ensures through a predetermined testing strategy that the product is capable of delivering its functional requirements robustly for a specified duration of time. This testing strategy should reflect the type of products designed and produced in a particular era. Nowadays, product requirements are changing and their designs are becoming even more complicated which represents a challenging opportunity to manage and perform associated required validation. This paper capitalises on proven concepts of Design for 6-Sigma (DFSS), axiomatic design, Failure Mode and Effect Analysis (FMEA), and robust design to present a lean approach to validating a product. The focus of this approach is to minimise redundancy and potential waste that can be observed in conducting hardware/CAE testing. An alternative to widely used ad hoc testing is a prescribed integration and sequence of testing that are performed to study specific families of failure modes in order to gain valuable information in reaching design validation.
