Iterative Design Process Spiral Diagram - UX & Product Development Framework #1821660 (License: Personal Use)

This spiral diagram maps the iterative design lifecycle, beginning with an initial issue and progressing outward through Research (stakeholders, briefs), Planning (concepts), Development, Manufacturing, Testing (in context), and Evaluation (fitness for purpose). Each loop reinforces learning, allowing refinement before final design and specifications. The model emphasizes adaptability and continuous feedback across project stages.

Used in UX, product design, engineering, and academic settings to teach or document agile, user-centered design workflows; supports content explaining iterative methodologies like double diamond or spiral models.
