Prototype

Prototype is a simplified version of the software that demonstrates core functionality and design - used for early feedback

Types of prototypes

  • Low-fidelity: paper sketches or basic wireframes to test layout and flow
  • High-fidelity: interactive mockups that closely resemble the final product
  • Throwaway prototype: built to explore ideas, then discarded
  • Evolutionary prototype: incrementally refined into the final product

Purpose of prototyping

  • Gather early stakeholder feedback before full development
  • Identify usability issues and missing requirements early
  • Reduce risk by validating assumptions before committing to full build
  • Communicate design intent to developers and clients

User interface (UI) design

UI design focuses on how users interact with the software - layout, navigation, visual elements

UI design principles

  • Consistency: uniform layout, colour, and typography across all screens
  • Simplicity: avoid clutter - only show what the user needs
  • Feedback: system responds visibly to user actions (loading indicators, confirmations)
  • Accessibility: design for a range of users including those with disabilities (contrast, font size, keyboard navigation)

UI design tools

  • Wireframing tools: Figma, Balsamiq, draw.io
  • Storyboards: sequence of screens showing user journey
  • Style guides: document colour palettes, typography, and component standards
