Frequently Asked Questions
How long does the full Double Diamond process take?+
For a medium-sized initiative (not a full product redesign, not a minor UI tweak), plan 5-8 weeks across all four phases. Compressed versions can run in 2 weeks (design sprint format). Large-scale redesigns may take 3-6 months.
Can I use just one diamond?+
Yes. Diamond 1 alone (Discover + Define) is a standalone discovery process useful for problem validation. Diamond 2 alone (Develop + Deliver) works when the problem is already well understood and you need a structured solution process.
How does this relate to Agile sprints?+
The Double Diamond is a macro-level process that sits above sprint-level execution. Diamond 1 typically happens before sprint planning. Diamond 2's Develop phase may span 1-2 sprints, and Deliver aligns with a build sprint. The key is that discovery happens before committing to sprint work.
Who should participate in each phase?+
Discover: PM + Designer + 1-2 engineers (for technical context). Define: PM + Designer + stakeholders. Develop: Full cross-functional team. Deliver: Design + Engineering + QA. ---
