Innovation Process model
Double Diamond structures innovation through divergent and convergent Discover, Define, Develop, and Deliver.
The four phases are not a linear gate process. Teams diverge and converge repeatedly, work people-centred, collaboratively and iteratively, and test the problem as well as solutions.
Which problem matters to whom, and which tested solution addresses it effectively?
Double Diamond uses two divergence-convergence cycles across problem and solution spaces. Assessments remain justified and context-bound.
Discover
Explore the problem space broadly with people, data, and context.
Define
Synthesize patterns and focus an evidenced challenge.
Develop
Generate, prototype, and compare several solution directions.
Deliver
Pilot, measure, adapt, and scale or stop the solution.
Update after new evidence or a material context change and retain the previous version.
For open problem spaces requiring research, synthesis, ideation, and testing.

The example demonstrates the domain logic of Double Diamond; worksheets remain blank.
Start with the core question: Which problem matters to whom, and which tested solution addresses it effectively?
For complex problems with a fuzzy situation, the method cleanly separates search space and decision. It first creates breadth in understanding and then focus in elaboration. This brings open questions, problem definition, and solution path into a traceable movement.
The double diamond structure allows first exploring the diversity of the problem space and then deliberately condensing the solution again. This makes divergence and convergence deliberately alternate instead of producing chaos and commitment at the same time. This makes the method especially useful when teams need to move between analysis, creativity, and implementation.
Double Diamond works because it deliberately separates exploration and condensation, bringing clarity to complex search movements. The format gains substance when both opening phases produce real material and both closing phases deliver a clear selection or problem definition. What is decisive are the transitions, the quality of the synthesis, and the connectability to implementation, so that the process does not remain stuck at a pretty model picture.
A project that contains both research and solution uncertainty is good for the kickoff, so that both diamonds show their effect. The transitions from broad to focused are formative; they need clear selection criteria and the courage to sharpen. Close with a visible problem statement, a solid solution path, and anchoring in the further delivery process.
The method guide walks execution through 4 phases, timing, 4 pitfalls, and clear stop criteria.

Fitting alternatives with decision guidance, followed by other related methods.
Instead of Double Diamond, choose Design Thinking when you want to combine problem understanding, ideation, and prototyping as an open process.
Forces eight sketches in a short time so direction options emerge and favorites become quickly comparable.
Parallel design teams turn a shared challenge into comparable concepts, open questions, and a consolidated direction.
Makes trade-off conflicts explicit, abstracts them into solution principles, and condenses testable concepts from them.
Combines dimensions and variants in a morphological box to find unusual solution combinations.
Opens the idea space, bundles contributions into theme clusters, and condenses them into a shortlist for the next step.
