"A goal without a plan is just a wish."
The local transportation authority of a USA state capital wanted to provide a better service for their customers. To help commuters plan journeys and get realtime travel information, they developed a new website together with new Android and iOS apps. Then they received a letter from a lawyer.
Not everyone was happy with the upgrade: the new apps were lacking accessibility controls and were unusable for the visually impaired. It wasn't just a simple matter of adding voice controls either, the apps needed a complete overhaul. To avoid having to go to court, the company had less than 12 months to bring in a new team and roll out completely new apps. So they did. The works started in January.
The new team then left in September, just after 9 months in, and leaving a little more than 3 months to find a solution. The project was abandoned, and so close to the deadline, the only choice seemed to be to remove the transport apps from the app stores altogether. In the end of the day, if there's no app, there's no need for it to be accessible either.
We joined the team in October with the promise to roll out the app in the very end of December. We applied two massive changes to the project.
The changes above allowed us to move really fast, and provide our client with more than just weekly progress updates: they could test the actual app developed, and had a huge impact in changing it with their feedback for the better. The apps were both released on schedule and in budget, in the end of December.
