When we started out on our Fast Track Journey it was dedicated to mobile projects. We knew that traditional IT-project management completely ruined projects for smartphones. They drowned in project overhead and no one quite understood that they had just asked for a native app looking like a traditional website. Prototyping with real look & feel (as opposed to wireframes) was part of the answer. Because of the mobile project background, the organization got an idea the Fast Track Development was only meant for mobile projects. It took some time to prove them wrong. However actual results are hard to ignore.
