My Design Process

The Double Diamond Model

Phases of this process are either diverging or converging.
During a diverging phase, you try to open up as much as possible without limiting yourself, whereas a converging phase focuses on condensing and narrowing your findings or ideas.

How it works

1. Discover

The first quarter of the Double Diamond model covers the start of the project. Designers try to look at the world in a fresh way, notice new things and gather insights.

Learning about your users:
  • Generative Research
  • Evaluative Research
  • Usability Testing
  • User Interviews
  • Surveys
  • Affinity Mapping
  • Card Sorting
  • Mental Models
Learning about the market:
  • Market Research
  • Comparative Analysis
  • Competitive Analysis
  • Heuristic Analysis

2. Define

The second quarter represents the definition stage, in which designers try to make sense of all the possibilities identified in the Discover phase. The goal here is to develop a clear creative brief that frames the fundamental design challenge.

Modelling your users:
  • Personas
  • Empathy Mapping
Analysing users tasks:
  • Task Analysis
  • Customer Journey
Eliciting clear product requirements:
  • Feature Analysis & Prioritisation
  • Product Specification with Business, Market, User & Technical Requirements.

3. Develop

The third quarter marks a period of development where solutions or concepts are created, prototyped, tested and iterated. This process of trial and error helps designers to improve and refine their ideas.

Iterative process:
  • User Flows
  • Site Maps
  • Task Scenarios
  • Storyboarding
  • Participatory Design
  • Screen Flows
  • Lo-Hi Fidelity prototyping
  • Visual Design
  • Usability Testing

4. Deliver

The final quarter of the double diamond model is the delivery stage, where the resulting project is finalised, produced and launched.

Providing support:
  • Final Prototypes
  • Presentations
  • Design Specifications
  • Support Launch

Measuring Success

I love using the Google HEART Framework to measure the outcomes of the User Experience Design process.

The Google HEART framework helps you measure the quality of user experience and the progress towards key goals and product-related decisions. The matrix below gives us a high level view of how effectively we're addressing the user's needs through qualitative and quantitative data.
