How Do the Five Phases Fit Together?

Each phase feeds into the next and iterations can occur between most phases:

1. Business objectives for UXE leads directly into user research.
2. User research may lead to a redefinition of business objectives if new opportunities arise, although this is unusual. User research leads into UX requirements.
3. UX requirement analysis work products are sometime verified with users recruited during the user research phase. UX requirement analysis leads into UX design.
4. UX design occurs in several iterations, with each iteration producing a model or prototype of increasing detail and granularity. UX design leads to UX evaluations.
5. UX evaluation iterates back to UX design until UX requirements are met.

Now that we have considered how UX is engineered, let's consider who uses these UX methods.
