Reliability testing to determine what will fail or when the failures will occur can be expensive. Organizations invest in the development of a product and attempt through the design process to create a product that is reliable. The design process has many unknowns though. This includes uncertainties about materials, design margins, use environments, loads, and aging effects. Using the best practices of design for reliability will minimize this list of risks to product reliability, yet it will not resolve all the uncertainty. Continue reading →
