What Are the Goals of Maintenance?

In my last post I looked at the history of maintenance. This post goes into more detail on the reasons why you should do maintenance. There are many more than merely to improve uptime. Let’s have a look at the different goals of maintenance. For illustration I will use the example of a car, since you are probably at least somewhat familiar with the maintenance of your car.

A Brief History of Maintenance

At the suggestion of multiple readers, I would like to take a deeper look into maintenance, especially total productive maintenance (TPM). Maintaining your machines and tools is important for your business. In many places, maintenance seems to be more reactive: if it breaks, fix it. Often, a better approach would be proactive maintenance: maintain it so it doesn’t break in the first place. In this first post in this series of articles on maintenance, I would like to look a bit into the history of maintenance. Subsequent posts will look deeper into why we need to maintain our stuff and how to do it. The overarching theme is guided by total productive maintenance, but I won’t hesitate to give my critical opinion where necessary.

Time to take a deeper look on how to set and use the minimum level in the supermarket. In this first post I will look at how to use a minimum level in a supermarket. The next post will look at how to determine a good minimum level.

Manufacturing Drives Prosperity

Manufacturing is one of the drivers of modern prosperity. Most manufactured goods become cheaper and cheaper over time, adjusted for inflation. Services, on the other hand, usually become more expensive over time. In this blog post I dive a bit deeper into these changes, using the USA consumer price index as an example.

Respect for People – Introduction

One important aspect in lean manufacturing is “Respect for People,” or more correctly, “Respect for Humanity.” But while it is mentioned frequently in presentations and books on lean manufacturing, what it actually means is often glossed over. And it is not an easy topic to write about. There is no “5 Steps to Respect for People.” Sorry. I have been thinking about writing a blog post on respect for quite some time, but it is difficult to write something substantial rather than just some anecdotes. It runs the risk of quickly drifting off into general management and leadership behavior. Nevertheless, I managed to write a series of three blog posts on it. Well, anyway, here we go…
