Project management - Process
Waterfall
A delivery approach that completes work through a sequence of planned phases
What's it for?
Organises work into large consecutive stages when requirements are stable enough to plan in advance.
For example…
A fixed regulatory change is fully specified before development begins
A waterfall project completes requirements first, signs off the design next, then builds and tests the whole solution in later phases
Think of it like…
Building a house floor by floor: you do not put the roof on before the walls, and redesigning the foundations mid-build hurts
