This post looks at how to reduce fluctuations (mura) in manufacturing. It is a continuation of the previous post that looked at why fluctuations are so bad. Be warned, tackling fluctuations is often a tedious task that never ends, but it one of the important fundamentals for lean manufacturing. After all, the more stable a system runs, the more efficient it is. Leveling is one major method to reduce fluctuations that focuses on the production schedule. Line balancing is another one that focuses on the work content.
Fluctuations are bad for manufacturing. In lean, unevenness is one of the three evils, besides waste and overburden. In this post I will give you an introduction to fluctuations. One option to handle fluctuations is decoupling, but this addresses only the symptoms and not the cure. In my next post I will show you how to actually reduce fluctuations.
The goal of a lean transformation is to shift the culture of an organization toward lean. In my last post I discussed a lot of prerequisites. In this post I would like to discuss how to actually do it. Be warned, there is no magic bullet. There is no simple trick that just turns lean on. It is a lot of hard work.
In my last post, I showed you a good example of all the things you can do wrong during a lean transformation. Learning from these mistakes gives a list of points that are relevant for a lean transformation. Let me show you what is important for a successful lean transformation.
Becoming lean is an aspiring goal for many companies. In my first post I showed you how Toyota does it … and why this may not work for you. In this second post of this series I will show you how NOT to do a lean transformation, and try to highlight common mistakes. In a subsequent post I would finally like to show you possible options you have for your lean transformation. Read on!
Companies continuously need to improve to survive. Lean can help them with this continuous improvement, so many companies aspire to become lean. The question is, how do you do that? How do you do a lean transformation, or more generally a change management? In this post I would like to talk about what is needed for a company to start their journey to lean. Be warned, it is not easy, and it does require a lot of support from the very top.
Line balancing is one of the important methods for improving your production system. The idea is to give every process the same workload so all processes are busy all the time. However, there are cases where it may be better NOT to balance a line. This post will look into when and why you may choose not to balance your line.
Today, AllAboutLean.com turns seven years old. Hurray! Amazing how fast time flies. Time to look back again on what happened. This is my 370th post on this blog. For seven years I have published a blog post every week going into the details of lean manufacturing and related topics (and once per year a birthday celebration post).
