Card-Based Control Systems for a Lean Work Design: The by Matthias Thurer

By Matthias Thurer

Many outlets have simplified their construction keep an eye on by utilizing card-based platforms comparable to kanban and incessant Work-in-Process (ConWIP). even supposing those structures supply an easy and powerful visible method for controlling production and repair operations, all too many outlets fight with failed implementations or in attaining effects that fall less than expectancies. those results should be attributed to a bad healthy among the particular regulate challenge and the answer applied.

This e-book takes a unique method of so much different books at the subject―as it starts off with an creation to the keep an eye on problem, rather than the keep watch over solution. Card-Based regulate platforms for a Lean paintings layout outlines how the issues encountered in commonplace production retailers and repair services will be characterised, which permits for enhanced challenge diagnosis.

The first 4 chapters of the publication lay the rules for challenge prognosis. the subsequent 3 chapters then speak about, in series, all the 3 "traditional" card-based keep an eye on structures: kanban, ConWIP, and Paired-cell Overlapping Loops of playing cards with Authorization (POLCA). The booklet explains how every one of those card-based regulate structures works and identifies the categorical kind of keep watch over challenge to which each and every process applies.

The subsequent chapters specialize in keep an eye on of stability through Card-Based Navigation (COBACABANA), a method built for high-variety retailers generating made-to-order, custom-made items. this is often the 1st publication to debate this novel technique, such as using playing cards to estimate due dates or supply time allowances.

The ebook closes with a framework that offers counsel on which process to use. This framework contrasts the keep watch over challenge with the keep an eye on resolution. the opportunity of combining card-based platforms is usually mentioned to create a nested solution.

One-piece flow vs. batching : a guide to understanding how continuous flow maximizes productivity and customer value

Even if batching usually appears to be like extra effective than one-piece move for person initiatives, the perform creates waste for different elements of the association that greater than offset its perceived merits. A silent productiveness killer, batching is a very tough approach to beat and, for that reason, a number of Lean tasks were destroyed through it.

Example text

In our definition of a stable shop floor, we see the shop floor as an aggregated transforming resource. e. the stable shop floor, there will be a stable level of work on the whole shop floor. In the second case, the work waiting in front of a station to be processed is stabilized. A stable shop floor does not necessarily imply stable stations; for example, a shop floor with two stations may always have a work-in-process of 10 orders (and thus be stable), but sometimes all 10 orders queue at the first station, and sometimes all 10 orders queue at the second station.

We will use a lot of “timeouts” to give you some breathing space, some time to conceptualize things and perhaps to relate them to your own shop. You may agree or disagree with our conceptual definitions. That is fine. There is no “true” conceptualization of a production/service system. But what is important is that you understand how we define and use the concepts in this book. Only this will make our suggestions on how to diagnose a control problem (and consequently use the most suitable control solution) clear.

E. the coordination of your business operations/processes—is the root cause of your problems. The objective of your company should be ongoing sustainable waste reduction. A card-based control system is only one (probably necessary) tool to achieve this. If your problem is quality or equipment availability, spending a lot of effort on implementing a card-based control system is, at the moment, probably not the right solution (although it may help to support other tools to address these problems).
