Keeping Some Slack in the Operating Room

MARCH 28, 2014

hospitalOperating rooms at St. John’s Regional Health Center, an acute-care hospital in Missouri, had been running at 100% capacity. When emergency cases—which make up about 20% of the full load—arose, the hospital was forced to bump long-scheduled surgeries. As a result, doctors often waited several hours to perform 2-hour procedures and sometimes operated at 2 a.m. Staff members regularly worked unplanned overtime. The hospital was constantly behind, according to this interesting article in Strategy + Business(Spring, 2104).

The rather surprising solution: Leave one room unused. Crazy idea? The facility was already being squeezed, and now comes a recommendation to take away even more capacity?

On the surface, St. John’s lacked operating rooms. But what it actually lacked was the ability to accommodate emergencies. Because planned procedures were taking up all the rooms, unplanned surgeries required a continual rearranging of the schedule—which had serious repercussions for costs and even quality of care. The key to finding a solution was the fact that the term unplanned surgery is a bit misleading. The hospital can’t predict each individual procedure, but it knows that there will always be emergencies. Once a room was set aside specifically for unscheduled cases, all the other operating rooms could be packed well and proceed unencumbered by surprises. The empty room thus added much-needed slack to the system. Soon after implementing this plan, the hospital was able to accommodate 5.1% more surgical cases overall, the number of surgeries performed after 3 p.m. fell by 45%, and revenue increased. And in the two years that followed, the hospital experienced a 7 and 11% annual increase in surgical volume.

The Barcode’s Intelligent New Rival

MARCH 24, 2014

Thin film technology

In June 1974 history was made at a supermarket in Troy, Ohio, with a ten-pack of Wrigley’s Juicy Fruit chewing gum. It was the first time a commercial item bearing a Universal Product Code was scanned by a cashier at the checkout. Forty years on, the barcode has transformed the world of commerce by providing reliable product identification, tracking and pricing. Nearly everything now comes with a barcode.

As revolutionary as it was, the barcode has limited abilities, reports The Economist (March 8, 2014). It can impart only the information it was printed with and that can be read by an optical device. The next generation of labeling contains tiny printable electronics able to generate, store and share information. The technology behind “smart labels” is a flexible film of electronics that can be printed like a barcode. The memory circuits which can be used by smart labels to store information are printed as a film of ferroelectric polymer sandwiched between two electrodes. A tiny 20-bit memory label can store over 1 million combinations.

Yet another advancement is called Near Field Communication (NFC). This allows a user to tap an NFC tag with a portable device, like a smartphone, to send or receive data. NFC is a more sophisticated version of RFID and is already used by some contactless payment systems. By incorporating NFC, smart labels will be able to communicate wirelessly. Besides conveying product codes, applications include recording storage times and temperatures for perishable goods like food and pharmaceuticals. Smart labels might even be programmed to automatically discount their prices in response to marketing campaigns. To gain widespread use, smart labels will need to be cheap. Basic printed-memory labels can be produced for around 2 cents. Printed sensor-labels cost 50 cents, compared with $10 or more for a system using conventional microelectronics.

Outsourcing Auto Workers at Nissan

MARCH 23, 2014

Nissan's truck line in Tennessee

Nissan, the first of many foreign automakers to set up shop in Tennessee, is leading a trend, writesThe Washington Post (March 9, 2014).Companies from Amazon to Asurion to Dell have outsourced their warehouses and call centers to the hundreds of staffing agencies that have cropped up in the region. Tennessee went from having 51,867 temporary workers in 2009 to 80,990 in 2012, while median wages have stayed flat. Temps make up 3.1% of all jobs in the state.

Tennessee holds its low unemployment rate up as a shining example of success in the global economy — the return of American manufacturing after decades of decline, and the future of work for those left jobless by globalization and technological change. Nissan was Tennessee’s first major investment by a foreign automaker, and has since attracted a constellation of suppliers that support thousands more jobs. Since the plant opened in 1983, the town of Smyrna has grown from 8,000 to 41,000. In the plant’s first 2 decades, getting a Nissan job was like winning the lottery.

But Nissan’s brush with bankruptcy in 2001 and a turnaround plan that involved new models and much lower production costs led to using temps into front-office functions. In 2007-2008, Nissan reduced its permanent workforce by 1/3. As demand returned, it started to backfill production jobs with contractors, too — first on the “pick line,” where workers run parts up to assembly, and then throughout the plant. Now a majority of its 7,000-person workforce is supplied by staffing agencies.

Many work for Yates Services, an in-house contractor that’s hired thousands of people over the past few years to ramp up production. Yates is like a company within a company, with separate bulletin boards, rules and procedures. The bona fide Nissan employees are easily recognizable through their logoed shirts, which Yates workers don’t receive. Yates pays between $10 and $18 an hour, which is about half what Nissan employees make. The gap in benefits is equally wide.
