by Dwayne Phillips A good test provides information—no more and no less. Let’s take a step back to the fundamentals of engineering and building things. Part of building some thing is to perform some tests on the thing. Why perform a test? The oft-cited answer is, “to show that the thing works.” Deep sigh. We […]

Descriptions and Predictions
March 17th, 2014 · No Comments
by Dwayne Phillips A description portrays what is now; a prediction estimate what may come. Sometimes we confuse the two at our peril. Some words are predictions. We use to them to portray our estimate of the future. Few of us are satisfactory as predictors of the future even though most of us think we […]

Be the Best – A Misguided Goal
February 20th, 2014 · No Comments
by Dwayne Phillips “Be the Best” is a misguided goal because it is based on other people. A few years ago, I worked for a government agency who proclaimed loudly and often that it was the Best fill-in-the-blank agency in the Federal government. I tried in vain to convince people that was a misguided goal. […]

The Napkin (or Envelope)
February 17th, 2014 · No Comments
by Dwayne Phillips The napkin or envelope is still one of the best tools for the engineer or manager or fill-in-the-blank. I have a(n old-fashioned) laptop computer, a smartphone, and a tablet – and I still write notes on a napkin. Yes, I am old, that is part of the explanation. Yet, there is something […]

Why We Do It
February 13th, 2014 · No Comments
by Dwayne Phillips Why do we do that? I find two answers to that question. The world is not complicated – at least if viewed from certain perspectives. Why do we burn fossil fuels? Why do athletes use steroids? Simple answer: because they work. But we move on to observing people do things that don’t […]

An Urban Myth: The Man, the Dog, and the Red Button
January 13th, 2014 · No Comments
by Dwayne Phillips I write an oft-repeated tale of factory with two occupants and one control mechanism. There are these urban myths. People tell a story over and over. It sounds pretty good, plausible, it could happen. Then I hear someone else in a completely different time and place tell the same story about a […]

HealthCare.Gov – An Excellent and Terrible Teaching Example
November 14th, 2013 · No Comments
by Dwayne Phillips Take care when choosing an example for teaching. Often what seem to be great examples are terrible in that people concentrate on the unintended. I have taken a lot of courses related to project management. I have taught a few. I have read a lot of books on project management, and, as […]

Healing and Sick People
October 10th, 2013 · No Comments
by Dwayne Phillips Sick people are harder to heal than healthy people. That sure makes everything more difficult, but that seems to be reality. Have you ever noticed that sick people are harder to heal than people who are well? Sick people have many problems. Those problems interact with one another in complex and often […]

Less Programming, More Typing
September 9th, 2013 · No Comments
by Dwayne Phillips Sometimes the best thing to do is put your seat in a chair, your hands on the keyboard, and type in all the data manually instead of writing software to do it. I experienced it at least half-a-dozen times in my 28 years in government: We need to track our inventory. Due […]

Blaming and Placating
August 8th, 2013 · No Comments
by Dwayne Phillips An incident in the cafeteria illustrates blaming and placating – incongruent stances created by a misconception of the self and the other. First, a story: A lady – a customer – is walking through the cafeteria at work. She falls to the floor. A second lady – the cafeteria manager – runs […]
