What are exercises —e.g. brainstorming, planning, etc— you've seen?

One of the most interesting learnings in working with individuals in different industries/professions, has always been the different techniques and exercises to facilitate successful sessions and processes for brainstorming, discovering, planning, designing, scoping, building, maintaining, etc.

That being said, I'd love to hear about your favorite (or recommendable) exercises.

Here are a few of mine:

Discovery:

- Design thinking for discovering solutions/products by first identifying pain points

- Event storming for discovering (software and business) domains, important groups of events, bottlenecks, and allocation of resources

Planning & Building:

- KANBAN and SCRUM used at appropriate times for effective planning and building

Scoping:

- Values, Principles, and Practices to guide prioritization and scoping discussions
