Paul Krugman has a piece of research advice, which is to “listen to the gentiles.” What he means is to pay attention to what smart practitioners say about their business in order to get economic ideas and insights. I recently had the chance to take a tour of large call center for a major global financial institution. It was interesting throughout and I thought I would share some of my notes.
Recruiting and Training
The company uses a tiered screening approach. They start with an online test. Some proceed to phone interviews and the finally round is in-person interviews. The HR director felt that the simulated work environment test was primary predictor of future job success—this matches up quite well with the industrial psychology literature on employer screening. He also felt that the best predictor of retention was how comfortable a worker seemed up front with the demands of shift-work.
The company made extensive use of their existing employees to recruit new ones. Referrals were highly valued because they were more likely to bring in candidates who understood the reality of shift-based call center work (and thus were less likely to turn over). It seemed to be less about bonding or reducing formal recruitment costs.
Long company-specific training period, but no general training (as Becker would have predicted). However, there are several other call centers in this region and the company does lose employees to them. The company-specific training period was surprisingly long (on the order of 3 months) and was conducted by more senior employees during low call volume periods.
Customers are segmented by value and routed accordingly. The company is multi-national and has call centers in several locations, including Europe, Southwest Asia and East Asia. The company’s clients are segmented based on value and routed to the call center that roughly corresponds to the skill level of the workers at the call center e.g., the best customers get the European call center and low-tier do not.
They are highly sophisticated at demand and supply management. Perhaps unsurprisingly, they are good at forecasting call volumes and staffing accordingly—with all of this done semi-automatically. They can adjust supply on the fly by calling off training, meetings etc. if demand spikes via building-wide announcements of status changes.
There was little evidence that much technologically-driven productivity improvement was on the horizon. Although the tasks are highly structured, there was no evidence that significant technology-driven productivity gains were on the horizon. All the big gains from automation already occurred many years ago (e.g., the ubiquitous “Press 1 for “Accounts”). There was no talk of Watson-like automation of responses to customer queries. The one technology they really wanted—and that would radically reduce their costs—was some easy way to verify customer identities over the phone. This alone would increase their productivity by about 20-30%.
There was little evidence that this would could be easily distributed. Most of the firm’s workplace policies seemed to be driven by concerns about regulatory compliance and fear of losing sensitive customer information and required a great deal of monitoring and control. It is difficult to imagine a substantial chunk of this work being done by a geographically distributed workforce.
