In my last post I talked about the different steps on how to do standard work. In this post I will go into more detail on how to write the actual work standard that is put up at the workplace. This will include quite a few examples in different styles, before I will go into a bit more detail for one example in my next post.
Standard work, or better called standardized work, is a popular method in lean manufacturing. It is closely related to standards and hence part of this longer series on standards, but with a focus on manufacturing or assembly. The actual creation of the work standard is only one of the last steps, and a lot of time is put into balancing the production and matching the customer takt. I have written a lot about some of these aspects before, but let me give you an overview.
This post of this series on standards looks at how to use the standard correctly, and how to improve a standard. Hint: It is all about the people actually using the standard. This series is again getting longer than I thought, as there is much detail to be discussed. The next post will finally look more at standardized work.
Standards are one of the cornerstones of modern manufacturing. However, they are not easy to write, and a bad standard can make things even worse than before. In my previous post I started to introduce how to write a standard. This post continues the topic of writing a standard with a few more tips.
Standards are the result of problem solving. In this article I will talk more about how to write a standard, but this is the outcome or the last steps of the problem-solving process. From this post onward I will look more at work standards, although the following is applicable to a lesser extent to part standards. Again, a standard is not something done on its own, but is part of a problem-solving process.
Standards are crucial to making your manufacturing system work smoothly. But where should you have standards? Sometimes you hear the answer, “Everywhere,” but this is not really helpful and I also think not really correct, either. Hence, let me talk a bit on why and where to have standards. This applies to all kinds of standards, not just the standardized work that is the most widely discussed one when talking about standards in lean.
Standards. You know they are important for manufacturing. You know Toyota and hence lean uses them extensively. But you may also know that they are not easy. I was thinking about writing a few blog posts on standards for a long time, but… it is a challenging topic. Let me give you my thoughts on standards and how to use them in lean manufacturing. But before going deeper into the use of standards over a few blog posts, I’ll provide a quick introduction on standards.
In my last post I looked at the behavior of the supermarket inventory for different kanban systems. In this post I will use this information to estimate how much the material availability of a system changes if you increase or decrease the inventory limit of your pull system (i.e., number of kanban).
Parts of this blog post are loosely based on chapter 13.2 of my new book All About Pull Production: Designing, Implementing, and Maintaining Kanban, CONWIP, and other Pull Systems in Lean Production.
