The maker of sophisticated medical equipment had reached a "plateau" in its efforts to boost customer service and optimize costly inventory within its global operation. Then it found a way to climb higher.

A conversation with Gregory L. Schlegel, adjunct professor of supply-chain risk management at Lehigh University.

Each disruption in global supply chains seems to bring a new surprise. On March 31 of this year, it was an explosion and fire at a chemical plant in Marl, Germany. The incident at the factory of Evonik Industries resulted in the deaths of two workers and caused damage that will take all summer to repair.

Proforma IdeaPress has managed to remain competitive in the market for printed promotional items, even though its plants are in the U.S. and customer requirements can be extremely complex. Company co-owner Pratt Pande tells how it's done.

Once a new technology tool becomes embedded in the business world, one tends to forget the doubt and confusion that marked its debut. As anyone over the age of 30 will recall, companies once debated the value of having websites. Early users of the internet were actively hostile to the notion of a network that was created for the defense and academic communities being co-opted by the commercial sector. Now, of course, any business that isn't on the internet is either utterly clueless or not serious about being a success. Yet we seem to be having the same debate all over again, this time centering on the proper role of social media.

Supply-chain professionals have been sounding the warning bell about the coming talent shortfall for several years now. But who's listening? At a time when the economy at large is coping with high unemployment and sluggish job growth, the notion of a sector that can't attract enough qualified bodies is tough to grasp. Still, that's the reality in the supply-chain world today, and it's only going to get worse.

How we love our information systems, our management theories, our best-laid plans. And how often they fail us. It reminds me of what the playwright and novelist Samuel Beckett once said about his work. "Each time one thinks one starts fresh, new," he mused. "Yet each time one reaches the same impasse. There are many ways to begin, many roads to it, but always the same impasse at the end."
