IMPLEMENTING RELIABILITY PHYSICS INTO THE DESIGN PROCESS: WHAT EVERY MANAGER AND ENGINEER NEEDS TO KNOW
Most engineers and management will agree that critical decisions regarding design and reliability should be based on robust analyses and data. Despite this concurrence, product teams within the technology space continue to use outmoded approaches for reliability assurance and risk mitigation. This includes empirical handbook predictions, like MIL-HDBK-217 and equivalent, arbitrary derating rules, reliability by similarity, prior experience, or even no reliability assessment until physical test.
This inertia is partially due to the difficulty of inserting new practices into an ongoing product development process. And the risk is high, since key performance indicators (KPIs) for Directors and VP’s are based on hitting cost and schedule targets, not necessarily using better reliability practices.
In this presentation, DfR will review the most common design flows and the common insertion points for existing reliability practices. Design flows will include revolutionary (new design), evolutionary (minor changes, such as obsolescence or price reduction), and ODM. Within each design flow, DfR will provide detailed recommendations on where reliability physics will provide greatest value and the specific detail as to the activity, information needed, and purpose.
At the end of this presentation, engineers and managers will have the foundation knowledge to improve existing processes and educate peers and supervisors as to the value proposition while minimizing any potential disruption. The long-term goal will be to reduce the engineering resources and time to market necessary to release product to the field while still reaching or exceeding reliability goals.
