Manufacturing Balancing Act: Pull Versus ERP
By: Chet Marchwinski | September 23, 2016
In this follow-up story to our case study about Phase 2 Medical Manufacturing, Inc.  , the company faces an enviable dilemma: because the lean transformation has spurred strong sales growth, Phase 2 needs a new or expanded parts warehouse. Instead, it expands the pull system by connecting the plan-for-every-part database that underpins one-piece flow production with the enterprise resource planning system, typically associated with big batch production.

Lean + Circular Principals = a New True North for Manufacturer
By: Doug Bartholomew | June 15, 2016
SunPower's lean journey resembled most others until it defined a new mission, a new True North. The mission statement changed from the business-like “install 10 gigawatts of solar panels by 2016" to the inspirational “change the way our world is powered.  " To achieve it, SunPower melded lean principals with those of the “circular economy” to launch what it called a CLean Transformation. Instead of following the traditional linear economic model of take, make, dispose, it follows a circular model of reuse, remanufacture, and recycle. Learn the business and environmental payoffs of linking lean and clean. More »

A gap can exist between current performance and an established standard or a new standard that you are attempting to achieve. A problem also can be unwanted variation in performance even when average performance appears acceptable. When even a single out-of-specification event is a More »

When trying to solve a problem, you want to identify underlying causes, which will help you to prevent fires rather than just extinguish them. By identifying the underlying causes down to the root causes, you can reduce the likelihood that a given problem will recur. The most common root-cause analysis technique in lean is the "Five Why's.  " This is practice of asking why repeatedly whenever a problem is encountered in order to get beyond the obvious symptoms to discover the root cause. For instance, Taiichi Ohno gives this example about a machine that stopped working (Ohno 1988, p. 17): Why More »
