Lean Math With Mark Hamel
The time observation form, also known as a process study form, is a basic and often-used tool for lean practitioners. Note that here we are talking about applying the continuous time-observation method and not the work-sampling method.
The form, in combination with a stopwatch, serves multiple…

Anew Critical Materials Hub led by Ames Laboratory, located in Ames, Iowa, is the latest of the U.S. Department of Energy’s five innovation hubs—which combine basic and applied research with engineering to accelerate scientific discovery in critical energy areas.
Many of the fastest growing clean…

NASA’s Voyager 1 spacecraft officially is the first human-made object to venture into interstellar space. The 36-year-old probe is about 12 billion miles (19 billion km) from our sun.
New and unexpected data indicate Voyager 1 has been traveling for about one year through plasma, or ionized gas,…

People are more likely to conserve energy if it’s easy to do. Knowing this, students working on Stanford’s entry in the Solar Decathlon green-building competition have redesigned household mainstays to make reducing energy and water consumption a cinch.
When Stanford students began designing…

Engineers speak a different language. My fellow engineers will label me a traitor for confessing this, but it’s true. Of course, engineers use the same regional language as everyone else, but the words themselves have meanings that are specific to engineers and that are different than everyone…

General Motors has joined the list of multinationals in the hot seat in India. In one of the largest vehicle recalls in the country, GM recalled more than 114,000 Tavera sports utility vehicles produced between 2005 and 2013 due to issues related to emission standards. But, as it turns out, there…

Failure. Just saying the word makes me cringe. And if you’re human, you’ve probably suffered through and overcome at least a couple failures. But when it comes to lean Six Sigma projects, there’s really nothing worse than having your entire project fail. Sometimes these projects…

Moore’s Law predicts that every two years the cost of computing will fall by half. That’s one reason why tomorrow’s gadgets may be better, and cheaper, too. But in American hospitals and doctors’ offices, a very different law seems to hold sway: Every 13 years, spending on U.S. healthcare doubles…

Chief financial officers (CFOs) throughout the United States are concerned by several risks on the horizon—including an overvalued stock market, interest rates that are expected to jump, and a shift toward temporary and part-time workers driven by the Affordable Care Act, and overall economic…

Hospitals are facing ever-increasing pressure to evaluate and cut costs. This isn’t surprising. Medical supplies represent as much as 30 percent of an average hospital’s total operating expenses. Regulatory and economic changes, and initiatives such as value-based purchasing, are also pushing…

The Service Employees International Union (SEIU) is supporting strikes by fast-food workers who want $15 an hour. According to Workers’ World, “Most earn the federal minimum hourly wage of $7.25 or close to it. They are demanding that McDonald’s, Burger King, Wendy’s, Yum Brand, and their other…

Measurement system analysis of uncertainty is one topic in lean Six Sigma training that is too often ignored or under-taught. I believe that it is under-taught because most instructors have never used or understood it. Therefore, this column will dive deep into what it is and why you should learn…

According to the U.S. Department of Agriculture’s Egg-Grading Manual, “Checks [aka “cracks’”] are an unavoidable problem in the marketing of eggs because eggs cannot be assembled, graded, packed, transported, and merchandized without some breakage.” Unavoidable. That’s the standard, I guess. The…

During the past two years, almost at regular intervals, we hear news about the failure of a Russian rocket launch. A few weeks ago, on July 2, 2013, a three-stage Proton-M took off from Baikonour Cosmodrome. The rocket started veering off course right after leaving the pad, deviating from the…

Conroe Machine is doing what most machine shops only dream of: hard-turning a family of parts around the clock in an unmanned cell that operates a “self-controlled” process. The company is proof that the dream is achievable for any shop ready to use the talents of today’s automation experts to…

Last month’s column, “Beware the Tukey Control Chart,” generated several questions of a fundamental nature that deserve expanded answers. These questions and their answers will be considered here.
Interquartile ranges
The Tukey control chart uses the interquartile range or IQR to characterize…

School bells have sounded the death knell of summer across the land. But as we’ve noted before, the U.S. Food and Drug Administration (FDA) didn’t take much time off to enjoy surf and sand. The agency capped a busy season last week by issuing a new guidance aimed at investigational review boards (…

I’m a fan of logistics, and as many kids do, I love water, too. I’m fascinated by how rivers move, how underwater streams move, how winds move. I’m fascinated by any kind of stream, even intangible, process-based ones.
I do understand the necessity of dams, of course, but I don’t agree that they…

It seems like every few years somebody, somewhere around the world asks, “What is quality?” or “What does quality mean?” I recently had the opportunity to make my own attempt at addressing this question when it was asked by the Deutsche Gesellschaft für Qualität (German Society for Quality).…

It’s wrong to intentionally make a promise you can’t keep. But it seems that too many companies are making this mistake, and it’s hurting their customer relationships. When Gallup surveyed more than four million customers, it found that one in five actively disengaged customers feel that the…

When coordinate measuring machines (CMMs) first came on the scene in the 1960s and 1970s, parts and work pieces were measured by well-trained inspectors in clean rooms and labs far from the shop-floor hubbub. In these controlled environments, cantilever-style (and eventually, bridge, gantry, and…

Played out on a computer over hundreds of generations, a survival-of-the-fittest programming method adapted by National Institute of Standards and Technology (NIST) researchers has spawned, of all things, the design for a more efficient rooftop air-conditioning system.
