Key Performance Indicator – or KPI – are measurements regarding different shop floor performances.

The Many Different Flavors of the OEE

If imitation is the sincerest form of flattery, the OEE (Overall Equipment Effectiveness or Efficiency) is indeed one of the most appreciated measures in lean. I counted at least eight different variants and adaptions of the basic OEE – although let me tell you that I am not impressed with all of them. Many of them seem to be theoretical academic constructs with little meaning for your shop floor. Also, identical acronyms and similar terms are often used in a completely different way, adding quite a bit to the confusion. On top of that, I think the OEE is used way too much in industry where it does not make sense, and many OEE numbers are heavily fudged. Anyway, let me show you the many different flavors of the OEE.

Good and Bad Ways to Calculate the OEE

There are different ways to calculate an OEE. I know of at least three different ways. However, some of them are easier and more practical than others.

Maybe you have seen a formula similar to OEE = A x P x Q. I see this formula often, but for me it is a very impractical way to calculate the OEE. Let me show you why by comparing the three different ways to calculate an OEE.  Continue reading Good and Bad Ways to Calculate the OEE

The A3 Report – Part 3: Limitations and Common Mistakes

In the last two posts I showed you the basics of the A3 report and the (possible) content of the A3 report. In this last post of this series, I would like to talk about common mistakes and the limitations of the A3 report. Overall, for me the A3 report is a minor tool to help organize the real work of problem solving, despite all the fuzz some make about the A3 report. Continue reading The A3 Report – Part 3: Limitations and Common Mistakes

The A3 Report – Part 2: Content

In my last post I wrote about four basic factors for an A3 report (one sheet / A3 size / with pencil / on the shop floor). This week I would like to show you what goes in an A3 report. The important framework here is PDCA (Plan, Do, Check, Act). However, in my view there is no single perfect A3 template that will fit all of your problems. Rather, an A3 is created on the go. Make the tool fit the problem, not the other way round! Continue reading The A3 Report – Part 2: Content

The A3 Report – Part 1: Basics

If you know your way around lean, you surely have hear about the A3 report, famously named after the DIN-A3 paper size. It is also known as the A3 problem-solving sheet. The goal is to get all the  necessary data on one sheet of A3 paper using pencil while you are on the shop floor. The A3 report is commonly used for problem solving, but also for project management or status reports. Continue reading The A3 Report – Part 1: Basics
