When a central question feels too large, the method breaks it into neighboring topic fields with their own depth of ideation. It holds structure and openness at the same time, so adjacent perspectives don't get lost. This grows an idea space out of a core problem.
Innovation Workshop method
Lotus Blossom
Expands a central challenge into eight themes and each theme into eight further ideas.
Lotus Blossom uses a 9×9 pattern: the challenge sits at the centre, eight themes surround it, and each becomes the centre of an outer 3×3 blossom with eight ideas. This yields up to 64 specific ideas.
Which 64 concrete ideas emerge when we fully expand eight main themes?

First step
Start with the core question: Which 64 concrete ideas emerge when we fully expand eight main themes?
Good to do first
Deep dive
Several thematic fields emerge from the core, each treated again as its own thinking surface. This nesting prevents ideation from circling on just one level and brings hidden neighboring problems to the surface. The result is especially valuable when a topic needs to be understood organizationally, technically, and from the user side at the same time.
Lotus Blossom works because it systematically expands a core problem into adjacent subspaces and idea fans derived from them. The benefit shows when the first level is set cleanly and the following fields produce genuine shifts in perspective rather than just filler material. This becomes reliable through thematic discipline, clear labeling, and later tracing back to the original problem, so breadth emerges without arbitrariness.
Put a question with genuine relevance in the center and make sure the first surrounding fields really represent different approaches. You should stay alert when side aspects start overshadowing the center; a brief return to the core question helps then. Close with a look at the most promising subspaces and derive a focused deep dive from them.
The method guide walks execution through 4 phases, timing, 4 pitfalls, and clear stop criteria.

Alternatives and neighbors
Fitting alternatives with decision guidance, followed by other related methods.

Instead of Lotus Blossom, when you need a calmer idea collection and don't want to fill a structured blossom with subtopics.

Varies a starting idea across seven targeted change questions and condenses approaches into a concept shortlist.

Opens the idea space, bundles contributions into theme clusters, and condenses them into a shortlist for the next step.

Combines dimensions and variants in a morphological box to find unusual solution combinations.

A strict timebox pushes quick idea volume first, then clusters and selects options after the burst is complete.

Deliberately flips the question toward the negative to expose risk themes and derive solid solution ideas from them.
