Core concepts
- Discover: investigate affected people and problem situations
- Define: use research evidence to set the scope of the problem
- Develop and deliver: explore alternatives and refine them through testing
Application
Use it when requirements arrive as proposed solutions, to re-examine the underlying problem and compare alternatives.
Limitations and jurisdiction
It is not a timetable in which each stage is completed only once. New evidence may require revisiting the problem definition and alternatives.
Editorial perspectives
- Broaden exploration: investigate overlooked users and causes.
- Focus convergence: quickly test solutions to an established problem.
