Case Study

A problematic conversion to a new software system for managing staff and tracking flights grounded flight operations at Spirit Airlines Inc. to a halt, resulting in passengers stranded in cities such as New York, Detroit and Palm Beach, Florida. The system-wide problems forced the Fort Lauderdale, Florida - based discount airline to book all available hotel rooms in many markets and to institute a nationwide disaster response program.

Sprit airlines president and CEO Jacob Schorr said the crisis wasn´t touched off by the new system crashing or other technical problem. Instead, the problem were caused by a lack of familiarity with the software on the part of Sprit´s employees-situation that snowballed at the airline after winter storms affected air travel in the northeast.

While the new scheduling system had been run in parallel with the airline old one from September through the end of the last year, Schorr said users could not negotiate the software fast enough to keep pace after the storms began forcing flight cancellations. "The people who operated the software were not longer as fast with it, even though they were proficient and they were trained", Schorr said "It´s one of those situations where your fingers are not connected to your brain anymore, and we were not prepared for that". Flights were also booked to capacity because of the crush of holiday travelers, making it more difficult to accommodate stranded passengers after the problems emerged, he said.

Compounding the situation even further was the fact that Sprit´s CIO post is vacant, said Schorr, who held that position until he was promoted to CEO in mid-2000. The airline began interviewing potential CIO candidates last month but has yet to hire a replacement. A hands-on IT executive might have been able to foresee the impending crisis and steer Sprit´s crew staffing department away from doing the software conversion at such a busy travel time, Schorr said. "The only way we could have avoided this problem was to have called off the conversion", he said. "But we obviously didn´t see the problem coming".

Henry Harteveldt, an analyst at Forrester Research who follows the travel industry, faulted Sprit for its timing. "You never want to do a cutover to a new software system during a peak travel period", he said. Sprit´s staffing department wanted the conversion to occur January 1 because the airline needs to track pilot and crew flight hours on a calendar bases in order to ensure that workers don´t exceed flying limits set by the U.S. federal aviation Administration. Making the switch a week or two later would have required the initial records for this year to be moved from the old system to the new one.

"Up until now, it´s been our policy to let individual departments manage their own projects and not involve the IT department", Schorr said. "That´s going to change. We need to have our tech people more involved". Harteveldt said such a hang-off IT policy is receipt for danger. "You don´t mess around the technology", he said. "It is not kind to the people who don´t understand it".

Schorr said the airline will have to spend at least the rest of month trying to win back passengers who were inconvenienced by the problems. Sprit, the largest privately held airline in the U.S, carried more than 2,00,000 passengers last year.

The airline will also have to mend its relationship with the New York and the New Jersey Port authority, which is considering pulling Sprit´s landing permits at the LaGuardia and Newark airports in the back of the ordeal. Port authority spokesman Stewon Coleman said that at one point. New York police were called to La Guardia to claim an unruly crowd of disgruntled passengers. "There were some near fist fights between some of the passengers who´d just had enough", he said.

The crisis also will lead to organizational restructuring at Sprit. Coleman said, although he added that specific changes haven´t been decided on. A week ago, the airline announced that it had returned to "business-as-usual operation". Schorr said the new software remains in place. "It was a matter of knowing how to use it", he said.
