Posts Tagged ‘Waiting Time’

When was the last time you called a business number, got put on hold and heard dead silence? In all likelihood it was some time ago. So why play music when customers are forced to wait? It’s not like anyone really enjoys hearing pabulum played at the highest fidelity permitted your phone’s speaker so there is a real question here for why firms should go through the effort. Slate has an article that tries to get at this question (Your Call Is Important to Us, Sep 8). If you prefer to listen instead of read, here is an NPR interview with the article’s author.

The first thing to recognize is that playing something for callers placed on hold aimed to solve a practical problem: If all you here is nothing, how do you know that the call is still connected?

But in the spring of 1962, an application appeared in the U.S. Patent Office, humbly titled “Telephone Hold Program System.” “In the course of receiving telephone calls,” it began, a bit grandly, before settling into the problem at hand: What to do about that dead silence the caller endured while calls were transferred, their respective parties chased down? Operators were supposed to check in again on callers who had been waiting; but what if they got busy? “In any event,” the application went on, “listening to a completely unresponsive instrument is tedious and calls often are abandoned altogether or remade which leads to annoyance and a waste of time and money.”

So the thought was that using music could improve customer service and operation efficiency. People would be more willing to hang on the line and thus would not need to call back later. Does that actually work? (more…)

Wal-Mart has had a tough go over the last few years. Sure, they are still a huge force in retailing but they have run into a variety of operational problems largely related to in-store execution. (See. for example, this post.) Now the Wall Street Journal reports that Wal-Mart is gearing up for the holidays by trying to address some customer service pain points (Returning to Wal-Mart: Human Cashiers, Aug 15).

In an attempt to lure more customers this holiday season, Wal-Mart Stores Inc. is promising to staff each of its cash register from the day after Thanksgiving through the days just before Christmas during peak shopping times.

The move, called the “checkout promise,” is aimed at addressing one of the retailer’s biggest customer complaints: long waits in checkout lines, which can cause even more frustration when positions aren’t fully staffed. The pledge will cover hours typically on weekend afternoons but which can vary by store.

“We feel good about price and having the top gifts of the season, so the next priority is about getting customers in and out of the stores quickly,” Duncan Mac Naughton, Wal-Mart’s chief merchandising officer, said in an interview. “Taking the possibility of waiting in long lines off the table will attract more people into stores.” …

On Thursday the retail giant said it allocated more hours to the front end of the store, to overnight stocking, and to deli and bakery to improve customer service during the most recent quarter.

Here are two questions that are worth thinking about. (more…)

Would you be more likely to go to fast food restaurant if it guaranteed how long you wait at the drive thru? Some McDonald’s in South Florida are doing just that (McDonald’s offers a 60-second lunch guarantee on weekdays, Aug 4).

McDonald’s guests at participating South Florida restaurants will receive timers when paying for their order in the drive-thru. The timers are then returned to the McDonald’s crew member when their food is presented. This guarantee promises that customers will receive their meal within 60 seconds of paying for it, or receive a complimentary lunch item on a future visit.

The guarantee doesn’t apply all day. Indeed, it is only in effect for an hour — but it is the hour that matters, noon to one.

Let me acknowledge upfront that this is clearly a gimmick. McDonald’s has been in a funk and their drive thru times have been climbing (along with the time of many in the industry). So this offers customers some assurance and maybe puts a little competitive pressure on some of the other players in the industry.

But as gimmicks go, I kind of like this one. (more…)

Why do you stand in line? In many Western countries, that is a silly question. You stand in line because that is what you do. Whether waiting to check out at the supermarket or get into a ballgame, standing in line is the norm. You stand in line because everyone else is standing in line. However, as a National Post article points out, standing in line is very much a cultural phenomenon and not just some inherent human trait (Everyone line up: Canada’s tradition of orderly queuing ‘foreign and strange’ to many newcomers, Jul 25).

“Lining up is seen as a universal sort of truth,” said J.J. McCullough, the Vancouver-based author of J.J.’s Complete Guide to Canada, an online primer for newcomers. “And if someone doesn’t adhere to the protocol then it must be because they’re uncouth or uncivilized, rather that this is a sort of idiosyncratic tradition that we’ve internalized.” …

At the Canadian School of Protocol and Etiquette, located in London, Ont., lineup training comes on the same day students are taught about North American-style introductions. Students are taught where to line up, how to maintain one’s proper place in the lineup and — most importantly — how close to stand.

“In certain cultures, queue etiquette is just not on the radar,” said school director Wendy Mencel.

So where does this tradition come from?

Have you ever wished you could tell the TSA what to do with itself? Now, you have that opportunity — at least when it comes to how they organize and manage their queues. To make things even better, they might actually pay you! The Transportation Security Administration has posted a challenge asking for people to develop a simulation model to tackle the capacity management issues of getting people through airport security. If you are interested in the challenge, the official call is here. Here are some of the specific considerations that need to be tackled:

TSA is looking for the Next Generation Checkpoint Queue Design Model to apply a scientific and simulation modeling approach to meet the dynamic security screening environment. The new queue design should include, but not limited to the following queue lanes:

  • TSA Pre✓™
  • Standard
  • Premier Passengers (1st class, business class, frequent fliers, etc.)
  • Employee and Flight Crews
  • PWD (wheelchair access)

The Challenge is to provide a simulation modeling concept that can form the basis to plan, develop requirements, and design a queue appropriately. The concept will be used to develop a model to be applied in decision analysis and to take in considerations of site specific requirements, peak and non-peak hours, flight schedules and TSA staffing schedules. Solvers are expected to provide the concept and provide evidence that it works as described in the requirements.

According to Nextgov.com, there are specific performance targets for different classes of customers (Attention, Passengers: $15,000 Prize for Whoever Can Speed TSA Screening, Jul 18)

The line, in this scenario, extends from the point where a passenger joins the end of the queue to the metal detector or body scan machine.

The rules for the challenge state wait times cannot be more than 5 minutes for PreCheck and 10 minutes for standard lines.

Have you ever heard of VidCon? Turns out it is, in the words of Wikipedia, “a multi-genre online video convention, held annually in Southern California since 2010. Originally conceived by Hank and John Green of the “Vlogbrothers” YouTube channel, the convention is the largest of its kind in the world, gathering thousands of online video viewers, creators, and industry representatives worldwide.”

My wife and I had never heard of it either until our teenage daughter (who for the sake of this post we’ll call Magenta) put on the full-court press to attend. For better or worse, we caved and today Magenta is Anaheim for the start of the conference with her mom in tow. They have in hand tickets that were purchased months ago. However, they also need to get their IDs for the conference. That was the first order of business today and led to a text I received a little before 9:00AM central time (which, allow me to point out, is not quite 7:00AM in Anaheim):

Just what does the longest line that Magenta’s Mom has ever seen look like? Take a gander (and see if you can spot Magenta).

So why bring this up? Beyond being able to publicly thank Magenta’s Mom for falling on this particular parenting grenade, it serves as a nice lead in to a recent Business Insider article on “Why People Wait In Hours-Long Lines For Shake Shack, Cronuts, And iPhones” (Jun 25). (more…)

Systems with randomness are inherently subject to delay. But how does that delay vary over the day? That is, if we think of a service setting with “peak” hours that in some sense resets every day, when are delays worst? Note that this would be relevant for, say, a restaurant that closes every evening or for a hospital emergency room that doesn’t officially close but typically does see a dramatic drop in volume in the overnight hours. Intuitively, one would expect that delays build over the day. Now Nate Silver at FiveThirtyEight has provided a graphical illustration of how delay builds for a stochastic system — specifically for US domestic flights (Fly Early, Arrive On-Time, Apr 19).
