DFR has been a term in and out of fashion for some time. One the many DFX type programs. DFR, unlike some of the other design for X programs has to exist within the overall culture of the organization to be successful. The premise that design occurs at the point of decision implies that each design my have the appropriate information to properly consider the decision’s impact on reliability performance.
Also, keep in mind, that decisions outside the design and development team also impact reliability performance. Marketing, finance, and supply chain elements of your organization make decisions that, too, impact how a product is perceived, funded, or created.
DFR is a way to think, consider, and decide to create a product that meets both business and customer reliability expectations. It is not a set of tools or tests, it is a way of getting things done.
