Prioritizing Prioritization for Product Designers

O-Object Guide. R-My Cat Saving Fire Department. C-OO User Stories. A-Details, details, details.
The 15-step ORCA Process consists of four iterative rounds of converting research into a clear, scoped, structure of your digital product. Those four rounds are Discovery, Requirements, Prioritization, and Representation. Each round hits on the four pillars: objects, relationships, calls-to-action, and attributes. Hence, ORCA.

ORCA — discovery, prioritization, requirements, sketching, prototyping, testing.
You might switch your Prioritization and Requirements Rounds. No harm, no foul.
