In everyday language, “in control” and “under control” are synonymous with “in specification.” Requirements have been met. Things are OK. No trouble.

“Out of control,” on the other hand, is synonymous with “out of specification.” Requirements have not been met. Things are not OK. Trouble.

Using this language, an obvious axiom would be: Take action when the process is out of control.

The everyday use of in and out of control is, however, unfortunate for control charts, the major tool of statistical process control (SPC). Why? Because in SPC these terms speak of processes as being stable or unstable. To characterize a process as stable or unstable, process limits, from process data, are needed. Specification limits are not needed.

Given the easy-to-understand basis for the action of meeting or not meeting requirements, coupled with the risk of confusion over the terms in control and out of control, why use control charts? If you are curious to see some of the benefits in doing so, read on. Two case studies are used.

‘Why are our changeovers taking so long?”

If you’ve asked this question on the shop floor, more than likely you were met with blank stares by your employees. Open-ended questions like this are overwhelming, so employees try to find quick answers that don’t really address the problem. They don’t have a starting point to form an answer.

But what if you asked a question with a specific, achievable goal, such as:

“What steps can we take to reduce changeover time by 15 minutes?”

You’ve then provided your employees with a measurable goal in the form of a question. Your workers may feel empowered to answer with some hands-on suggestions for incremental changes, such as reducing setup steps or combining workstations. This in turn could not only reduce changeover time, but also significantly eliminate wait times and inventories.

CEOs are stepping forward to confront public policy issues that often extend beyond their core business, in part at the urging of their employees, write Caroline Kaeb and David Scheffer in this opinion piece. Kaeb is co-chair of the Business and Human Rights Pillar and a senior fellow of the Zicklin Center for Business Ethics Research at Wharton. David Scheffer is the Mayer Brown/Robert A.

It takes more than a flashy website and clever promotional emails to compete in the manufacturing marketing arena. Chances are, your larger competitors are pitching similar products and services to the same client base. Your company’s industrial solution may be to offer state-of-the-art features at a reasonable cost, but do these benefits really outshine your larger competitors? Why should a potential customer choose you from a sea of manufacturers? To stand out in the crowd, you must first define your company’s unique value proposition.

Taking the first step: How to define your unique value

A value proposition goes beyond delivering your promised products and services. Your unique value proposition should explain how you plan to solve your customers’ problems in a way your competitors can’t.

During the early 1980s, GM, Ford, and Chrysler established the Automotive Industry Action Group (AIAG), a not-for-profit organization with the mission “To improve its members’ competitiveness through a cooperative effort of North American vehicle manufacturers and their suppliers.” In the late 1980s, U.S. automotive suppliers, through the auspices of the American Society for Quality (ASQ), approached the VPs of purchasing for GM, Ford, and Chrysler and explained the burden of multiple standards that were being imposed on the supply base. Not only where there multiple OEM standards, there were hundreds of tier one standards as well.

How often do you check your phone at work? Maybe you’re reading this article on it right now (Don’t worry; we won’t tell.). Smartphones were a revolution for workplace distractions, but they can also be tools for productivity.

I recently attended the IBM Watson IoT Exchange event in Orlando, Florida, the AI giant’s annual conference for its Watson solutions. It brings together users and developers of multiple IBM IoT products, including Maximo enterprise asset management.

As I attended the keynotes and workshops of the Maximo stream, I noticed a trend: Several of the featured monitoring, analytics, and asset management solutions required or recommended the use of a consumer electronic device, such as a smartphone, consumer tablet, or augmented reality headset.

A frog the size of a fingernail. A poncho-clad farmer leading his mule. A tree, some intertwining leaves, a silhouetted figure holding a pot. Such logos are stamped on labels of coffee, cocoa, mangoes, jeans, and myriad other products, certifying that the object for sale is in some way “sustainable”—made, in other words, in a way that meets humanity’s needs without jeopardizing the ability of future generations to meet their own.

Ryan Tillman-French sat at his seventh-floor desk early on a Thursday morning, the skyscrapers of downtown Boston crowding the windows behind him.

On a laptop in the nearly empty office, he worked on code for a web page he was developing for his employer, the learning materials company Houghton Mifflin Harcourt. In half an hour, he needed to join a conference call about changes to the company’s website.

He had been at Houghton Mifflin Harcourt for four months. Coding he liked. Meetings, not so much.

“That’s one thing I wasn’t warned about when it comes to the corporate world,” he said. “So many meetings.”

One of my hobbies is building and flying radio-controlled model aircraft. Not the small foam ones from Kmart but larger 2-m wingspan craft. It is a lot of fun and usually very relaxing.

My birthday was a few months ago, and for the first time I was given a plane. Somehow my family read my mind, and I ended up with exactly what I wanted.

I have not spent a lot of time on this hobby during the last year or so. These days you can buy the aircraft in what they call ARF (almost ready to fly) format where the plane really just needs final assembling, fitting the control gear and motor, and it’s done. The process should take about 4 hours or so. This was the type of plane I was given, and I was really looking forward to spending the day assembling the kit and making it ready to fly the following weekend.

I wanted to fit an electric power setup and started to look through the plane to see if any modifications were required. There were a few mounting holes that had to be relocated; nothing major, I thought.
