When making an app it is important to test early on in the design process, as well as test often because early tweaking makes a huge difference. Making multiple testing prototypes, even minimal and cheap are important. The group that worked on designing an app for this blog, made multiple sketches, some on sticky notes. It is also important to be aware of the communication between the executive manager and other members in your design team when creating this app. Also make sure to get a lot of feedback about your app from multiple people, before releasing.
