Why Are People Using Line and Bar Charts, not Control Charts?

If you look at improvement project posters at quality conferences around the country, you’ll find that almost everyone is using Excel line and bar charts. Even after decades of Six Sigma training and association membership. What’s the hold up? Here’s my take:

“Hi, I’m Jay Arthur, author of “Lean Six Sigma Demystified” and QI Macros [software].

“Every year I look at lots of improvement posters and I keep wondering, “Why isn’t anyone using the tools of Quality?” Control charts, Pareto charts, histograms… Most of them are just using plain old Excel line and bar charts. Now it might be because they don’t know about the power and beauty and how easy it can be now to do Control charts, Pareto charts and fishbones.

Work ON your business, not IN it.

COVID-19 has slowed business for much of the nation. Here’s how you can make use of the time:

“Hi, I’m Jay Arthur, author of “Lean Six Sigma Demystified” and the QI Macros [software].

“I don’t know about you, but with this COVID virus thing going around, business has slowed a little bit, but that’s great! That gives us an opportunity to start to focus and work ON our business, not IN our business. Now is the time to start to find ways to simplify, streamline, optimize everything that you do so that when things come back on you’ll be ready for it and you’ll be faster, better, cheaper than you ever were before.

Shift from Manufacturing to Supply Chain

The July-August, 2018 Inc. magazine has an article (pg. 22) about manufacturing vs supply chain service jobs. From 1999-2015:

  • Manufacturing jobs declined from 12.5 million to 8.2. Supply chain jobs increased from 13.4 million to 20.0.
  • Manufacturing salaries climbed only slightly from $54,800 to 59,800 while supply chain jobs rose from $72,600 to $85,200.

With increasing manufacturing automation, more jobs are being created around supporting production than actual production. Something to think about.

Lean Six Sigma for Manufacturing?

In Chris Anderson’s new book, FREE, he that almost 30 years ago (1981), the Fortune 100 companies all made something. Now, only 32 do. The other 68 traffic in ideas.

While Lean Six Sigma developed to help manufacturing, it has failed to keep up with the times. It’s still mired in the manufacturing model of reality. What are the new opportunities for Lean Six Sigma?

  • Back office operations like orders, invoicing, purchasing, and payments.
  • Sales and Marketing
  • Information Technologies

Anderson argues that much of the economy no longer produces atoms (i.e., products) but manages bits and bytes of information (e.g,

Lockheed F-22 Fighter Repair Problems

The Washington Post reported that mean time between critical failures in the F-22 is only 1.7 hours pushing it’s cost fly to $44,000 per hour. On average, the Post reports, only 55% of the fleet is available to fulfill missions.

In Six Sigma terms, that’s a 45% defect rate or less than two sigma.

The 4-50 Rule: The most common cause of maintenance problems: the radar-absorbing skin is vulnerable to rain and abrasion. Rain and abrasion seem like things that should have come out in a failure modes and effects analysis somewhere along the line.

What are the root causes of this problem?
