DFA tools essential to your product development strategy

by | Dec 25, 2019

The authors Jake Felser and Chris McCasin from Cooper Perkins give you few essential DFA tools in this article to help you get your DFA strategy right. The tools are briefly explained with examples. I highly recommend reading the full article if you are getting started with developing an IoT product which you want to be commercially viable.

The authors make a case for involving DFA in your product development journey from start to finish. The tools explained in the article will prevent a lot of rework, and hence cost escalations at later stages. One of the interesting insights is that these tools can also help you shortlist a contract manufacturer (CM) early on as the capabilities needed will come out with the exercise you do with these tools, and inputs of CM through your design process also helps in the long run. The authors say that even if you want to build domestically in low volume and then move to Asia for larger volume production, you must still plan for DFA from the beginning to avoid major reworks.

I think the tools - Production Flow (PFlow) and Failure Mode Effect Analysis (aFMEA) are quite handy and easy to use for planning an effective DFA strategy. PFlow tool helps you map the entire assembly process; where the parts come from and where do they go after every stage of assembly which unravels inefficiencies. aFMEA on the other hand helps reveal where things could go wrong in the entire process, what could be the repercussions on such failures so that you can put in place all the preventive measures.
