To meet the new requirements, the solution had to be rebuilt from the ground up. At the same time, it was important to minimize disruptions and to not create obstacles for the ticket inspectors. Accordingly, it was of outmost importance to build a solution that was intuitive and simple to use.
Another challenge was to find a better solution than ISS current plan to have two separate handheld devices, including one device for our ticketing solution and a second device for validating tickets in SL’s mobile app that had been developed by a third party. Tickets generated by the third party app had to be scanned with a separate device provided by that app developer.
In addition, we had to deliver the solution in a very short time period. The assignment was received in November with the expectation to deliver a solution by mid-December and with the rollout planned in the beginning of 2018.
