What is the right order in the UCD method?
-
Plan->Analyze->Design->Test
-
Analyze->Design->Test->Plan
-
Design->Analyze->Test->Plan
-
Design->Analyze->Plan->Test
The UCD method follows Plan (define scope and users), Analyze (research user needs and context), Design (create prototypes and solutions), Test (evaluate with users and iterate). You cannot design before understanding users (Analyze must precede Design), and testing happens after design, not before.
The User-Centered Design (UCD) process, as taught here, follows a sequential lifecycle: first Plan the project and understand goals, then Analyze user needs and requirements, then Design the interface/interaction based on that analysis, and finally Test the design with users to validate it. Doing these out of order (e.g. designing before analyzing needs) would mean building a solution before understanding the problem, which defeats the purpose of a user-centered process.
