Description¶

The 5-Phase UX Design Loop is "a practical, iterative process for reducing uncertainty, learning from users, and quickly making informed product decisions." It comprises five phases: (1) Get Aligned, defining the problem and key product decisions with the team; (2) Design the Concept, starting from users' "jobs to be done"; (3) Translate to Testable, using AI tools to build a functional, testable app; (4) Test with Real People, testing "just enough" to make product decisions; and (5) Synthesize and Decide, then returning to Step 1. Education R&D teams can adopt it to develop products grounded in user needs and evidence.

Design Implications¶

Context¶

Requirements¶

• Teams align first on the problem, the key product decisions, and what they need to learn before designing concepts
• Testing must build in enough interactivity that users can give meaningful feedback on a tangible prototype

Constraints¶

Target Learners¶

• education R&D teams developing learning products

Target Learning Objectives¶

• user-centered product development
• evidence-informed design decisions

Claims¶

• Five Screenshare Sessions Beat Large Survey [+W]
• Ai Compression Frees Human Led Alignment [+W]
• AI-supported prototyping combined with educator feedback loops accelerated development and surfaced usability issues early in one K-2 literacy tool project [+W]

Related Theories¶

Examples¶

• AI prototyping and research toolset: V0, Cursor, Mobbin, Figma, and Great Question
• Distinguish product users from purchasers and recruit representative users through school-like community settings
• Use small-scale learning metrics during iteration and reserve proof metrics for later stages
• Product Testing
• Use iterative design with short feedback loops and multiple user-feedback methods during product development
