Engineers often talk about the importance of design for reliability (DfR) and the impact it has on a product’s overall efficiencies and success. So, let’s take a look at DfR fundamentals and how companies employ it to their best advantage.
Essentially, DfR is a process that ensures a product, or system, performs a specified function within a given environment over the expected lifetime.
DfR often occurs at the design stage — before physical prototyping — and is often part of an overall design for excellence (DfX) strategy. But, as you’ll soon find out, the use of DfR can, and should, be expanded.
The complexities of today’s technologies make DfR more significant — and valuable — than ever before. Some of these reasons include:
Most companies apply DfR at the design and development stage of a given project development cycle. However, this common practice comes too late in the development process.
Successful DfR requires the integration of product design and process planning into a cohesive, interactive activity known as concurrent engineering. Keep in mind, it’s less expensive to design for reliability than to test for reliability. When you are implementing reliability considerations in the concept feasibility stage, you are making all your decisions down the line with reliability in mind. Therefore, DfR is most effective in the concept feasibility stage.
With the goal of simultaneous design optimization, the typical engineering silos are counterproductive. Instead, concurrent engineering hinges on contributions from all essential project team members. As a result, those that need to be included in DfR include:
The processes you need to complete to ensure a product or
system is reliable is long, but it’s worth it. You can better understand and
rely on your products.
Here are some DfR best practices that can apply to the development of nearly any project. These best practices also guide the process along.
