To build it, we’re going to use an Agile methodology, where we work in two-week “sprints.” In each sprint, we’ll have a list of “user stories” representing the work we’re doing. To officially complete a user story, we’ll need to demonstrate that story functioning properly in a shared development environment.

To be able to demonstrate working features, we’ll have a set of databases with specially chosen data that can simulate all of our edge cases and user flows. Setting up this data is time-consuming because our app is complex, ...
