SUPPLY CHAIN WEDNESDAY

________________________

By Jeremy Schaar

Six Sigma has been really amazing. It’s helped companies around the world improve their products and processes. How? It gives a company a system for finding and eliminating defects.

There’s lots of good vocabulary and ideas with Six Sigma, so I’ll spend the next few weeks talking about it. For today, you’ll learn about DMAIC. You’ll gain some great vocabulary and understand better how to improve products and processes at your job.

What’s DMAIC? It’s one of the most important ideas in supply chain management. And, actually, it can mean two things.

Dumb Managers Always Ignore Customers

OK. This isn’t the real meaning, but it’s an important joke. Customers should always be the most important part of any business. So only dumb (not smart) managers forget about customers.

Actually, DMAIC stands for:

Define Measure Analyze Improve Control

These are the things you should do in order to make products and processes better.

Define: I like to think of this step as getting organized. This can include many things. For example, you should choose a project and your goals, decide who will work on the project, and be very clear about what customers feel is most important. The things the customer feels are most important are called CTQs (critical-to-quality characteristics).

Measure: In this stage, you check how well you’re doing. This means learning what influences the CTQs and how to check them.

Analyze: Here, you look at the data from your measurements and figure out what’s causing defects. Another way to think of it is to learn what’s causing variation.

Improve: After analyzing, you should try and make things better. You need to remove the causes of the problems. You should also check how important different things are to the CTQs.

Control: Now that you’ve made things better, you should make sure they stay better.

That’s the basic process for Six Sigma. In the future, we’ll look at everything in much greater detail.
