The engineer becomes a dotor

Nice analogy, Dave. Looks like there are some essential steps in problem solving that can be applied widely.

The “pilot” article for Sherlock Ohms

Nice article, Dave.  It sums up very methodically, what engineering and evaluation is all about.  It almost could be the "pilot" article for Sherlock Ohms.  Maybe at least it could be re-printed as an introduction to engineering, perhaps on the inside cover of a curriculum syllabus. Sums it all up quite nicely.

I like the saying, "When you hear hoof beats, think horses, not zebras." It could apply to a lot of areas of life, not just engineering. But I think it's a great way of saying, "Consider the most obvious problems first." Nice article.

Good point, Chuck. I'm not familiar with the horses vs. zebras quote. Is that saying that it's more likely to be horses than zebras?

Talking about hoof beats. I was in southern New Mexico last week and someone was a few minutes late to a meeting because a heard of wild horses crossed the highway and he had to wait for them to pass. It's still the wild west out here.

Jim,

I agree. The methods described in this article is exactly the steps I used when doing a Root Cause Analysis on Electrical-Electronics Systems. A key item to  this method is documentation. Without documentation, the analysis activity becomes quite difficult to initiate because of the lack of information to investigate/research. The more information gather, less chance of going down a rathole trying to resolve the problem. Very nice article indeed.

When I first read the title I though this couldn't be possible. Turns out I was right, as I can conclude the same after reading the piece. However, even though the title is not right, the content is spot on. As engineers, we love to dig into the tests directly and none or very little consideration is ever given to the 'medical history' of the part we are diagnosing.

Thanks Dave for such an informative post , i totally agree with the analysis method that you have mentioned i also used to follow almost the same method of technical analysis when was working inthe engineering department .First of all we used to consider the issue that customer facing , then we try to dig out the reasons for the issues and comparing how exactly the device should work if it was working properly then testing all the possible reasons by trial and error method .Hence almost in all technical departments the same method of analysis is being followed .

 Hooves and Zebras - Thats Occams' Razor (look it up). It says, the simplest explanation is nearly always the correct one. Try telling that to the conspiracy theorist camp.

Nice article, thanks.  I thought this sort of problem-solving approach was second nature to engineers, but maybe I am mistaken.  I was raised by a medical professional, so maybe the DDx rubbed off on me when I was a child.

What happens when the patient gets better before the doctor finishes the diagnosis?  Then the doctor gets paid, anyway.  In engineering, we call this an intermittent problem, which can be much more difficult to diagnose.  How about writing an article about this sort of diagnosis?  Customers and Management don't think highly of the engineer when the problem comes and goes.

Differential analysis is used in management and accounting as well, sometimes to find errors.

Wild horses are a real nuisance in some areas, like Mesa Verde National Park, for example:

Iterative design — the cycle of prototyping, testing, analyzing, and refining a product — existed long before additive manufacturing, but it has never been as efficient and approachable as it is today with 3D printing.
People usually think of a time constant as the time it takes a first order system to change 63% of the way to the steady state value in response to a step change in the input -- it’s basically a measure of the responsiveness of the system. This is true, but in reality, time constants are often not constant. They can change just like system gains change as the environment or the geometry of the system changes.
At its core, sound is a relatively simple natural phenomenon caused by pressure pulsations or vibrations propagating through various mediums in the world around us. Studies have shown that the complete absence of sound can drive a person insane, causing them to experience hallucinations. Likewise, loud and overwhelming sound can have the same effect. This especially holds true in manufacturing and plant environments where loud noises are the norm.
The tech industry is no stranger to crowdsourcing funding for new projects, and the team at element14 are no strangers to crowdsourcing ideas for new projects through its design competitions. But what about crowdsourcing new components?
It has been common wisdom of late that anything you needed to manufacture could be made more cost-effectively on foreign shores. Following World War II, the label “Made in Japan” was as ubiquitous as is the “Made in China” version today and often had very similar -- not always positive -- connotations. Along the way, Korea, Indonesia, Malaysia, and other Pacific-rim nations have each had their turn at being the preferred low-cost alternative to manufacturing here in the US.
