Too many wishes, one deadline
A school asks for a new attendance app. The wish list has 40 items. There is money for 15, and the term starts in six weeks.
The team cannot do everything. It must choose. Some ways of working are built for exactly this.

DSDM and MoSCoW
In DSDM, three things are fixed from the start: cost, quality and time. Only the scope (how much is built) can change.
So the team must choose what to build. DSDM uses MoSCoW. Must have: the system fails without it. Should have: important, but there is a way round. Could have: nice to have. Won't have this time: left for later.
Your turn: sort the wish list
