Besides performance (unavailability of application as cited by crew to the helpdesk), revenue pilferage was one of the biggest pain point for the airlines to seek APM initiative. The crew would often site the unresponsiveness of the application, resulting in missed sales / revenue inputs from crew members after the flight lands. Because of these missed entries, the revenue won’t get recognized and the supply chain forecast for the eatables and other items went for a toss. Majority of times the issues were not being reproduced in the test environment. Also, there was very little visibility into the system as well as the network available at the airport, since it was outside the airline’s network and hence very little troubleshooting could happen.
