DFT vs Lean
In-Depth Comparison Included
DFT Vs. Lean
One of the most common comparisons when considering manufacturing ideologies, is between Demand Flow Technology and Lean Philosophy.
Lean takes an activity by activity approach to achieve its goal. The output of each activity is a small incremental improvement achieved through the application of the tools within the Lean toolbox. Typically, after long term implementation you will have a Lean environment where you have achieved several small incremental improvements along the way.
In contrast, Demand Flow Technology is a complete business strategy that looks at the entire manufacturing environment. The technology uses mathematically based tools to redesign the process and achieve an Operational Cycle Time that is based on the Demand at Capacity. This is where the differences between DFT and Lean begin.
DFT drives companies to adjust their process volume and mix every day based on actual customer demand. The demand driven technology reduces inventory and working capital costs, therefore improving speed-to-market. Demand Flow also focuses on in-process quality, forcing quality checks throughout the process, rather than at the end.
It's all in Costanza's book, The Quantum Leap: In Speed-To-Market, which has sold more than 650K copies and has been translated in five languages.
