Stages of application design
Design, build, evaluate, and refine your application in stages where possible. In each stage, maintain a primary focus.
•
Stage 1: Understand the product requirements and user goals
•
Stage 2: Develop the concepts and build the workflow
•
Stage 3: Organize the content on the screen
•
Stage 4: Incorporate the visual design
During each stage, design with your users in mind. Incorporate user research methods at each stage. User research helps
solve issues with the application throughout the design process and the results help to identify whether the application
meets user expectations.
