Quick Response Manufacturing or QRM is a modern response to the tough market conditions that many companies face. Why do we need this modern response? Well because “old methods” (that is what the author calls all that TOC, Kaizen, Lean, and Six Sigma kind of things) are insufficient.
Is that so? Is QRM the right methodology to obtain a competitive advantage in current market conditions? Well, market conditions were always tough, and companies always faced challenges to adapt on time. That is true and it’s not going to improve. So no matter what commercial name the author uses, as soon as it can help, we have to learn it.
There were really some good ideas in the book: QRM cells and extra capacity to add flexibility and reduce lead time, POLCA (Paired-cell Overlapping Loops of Cards with Authorization), and EOQ calculation… all that is value-added information. What does not add a lot of value is this new branding. Thus 25-year-old “modern approach” is still not widespread.
The book provides a great explanation of QRM, although lacks a kind of evidence base. Everything is explained on the level of logic, but without concept proof, it’s more like a pitch deck. Good one though.
There were also a couple of things left unclear for me. For example, the author discusses the ways to make a QRM cell really an independent part of the enterprise. Seems to me that a small group of people, that hold all the know-how and do all the work does not need an enterprise that only collects a tribute… This risk was not discussed in the book.
The other one is the capacity of QRM cell. The author describes different ways to improve it but avoids the question of the upper limit. What will happen if the QRM cell lacks some capacity? We may add some machines and people there and there. If the market and demands are still growing, we may add even more. Naturally, QRM cell will transform to conventional enterprise with all the inefficiencies. Just by growing. So where is the upper limit? When we should say “stop” and instead of growing, duplicate the QRM cell? How to manage the demand with 2 duplicated QRM cells? And who will do it? Another QRM cell? Shall we call it a planning cell then?
So, in general, it is a must-read book. But this is a book that requires separating the wheat from the chaff while reading.
