Design for Manufacturing & Assembly Best Practices

Defining the parameters of Design for Manufacturing and Assembly (DFMA)

Beginning with fundamental cost drivers and ending with checklists of cost and risk reduction recommendations, DFMA provides a practical toolset of approaches used in creating the most efficient/effective manufacturing and assembly processes.  Encompassed in this approach are considerations incorporated into the design and development activities associated with the product lifecycle, including reliability, testability, maintenance/service, ergonomics, safety and environment to name a few characteristics.  Generally, these parameters are all included in the design to look at the product from cradle to grave and ensures that all stakeholders in the product, from designer and factory workers to end users, will have their needs addressed.  When DFMA is implemented in a systematic manner there are benefits to speed to market with successful roll-out, lower production costs through increased automation as well as a reduction of design complexity.


Product and process must be co-developed to achieve high manufacturing yields with minimum rework or rejections.  Process capabilities must be matched to the product design tolerances in order to achieve:

  • Reduction in process related manufacturing defects
  • Improved long term product reliability
  • Virtual elimination of rework/repair
  • Reduction in Unit Production Cost
  • Enhanced effectiveness of Statistical Process Control
  • Increased focus on “sensitive” design elements
  • Decreased need for engineering/process changes


To achieve these conditions, concurrent engineering discipline…… download below

Supplier Quality

A Management Approach

Which of your suppliers are helping meet your quality and customer requirements and which are not?  Having tools in place to understand impacts, both positive and negative, from the supply base is critical to ensuring you meet your customer requirements. Translating key metrics that drive your business to the supply base and ensuring each of the suppliers is providing metrics and data to monitor their performance will enable a higher level of performance and be a guide to understand which suppliers are generating quality or other issues and need support.

Quality Metrics from all suppliers enable regular and timely management reviews to prevent supplier quality from impacting end product quality.

Supply Chain Challenge – Partner with Small Business Suppliers to Drive Quality, Cost, & Delivery

Driving Long Term Improvement through Supplier Partnering

The strength of the Supply Chain for every manufacturing business is critical to driving performance. Working with suppliers to drive improvement into their processes improving quality, cost, and on-time delivery will directly flow upward to the manufacturing and assembly businesses utilizing the improved supplier. The sometimes-hidden cost that erode earnings from poor performance of the supply chain can be turned into a positive if these suppliers develop strong systems and consistent performance.

Investments into critical suppliers will translate to direct improvement in quality, cost, & delivery – improving earnings
