Every design decision can make the user experience better or worse. Successful inclusive design requires informed decision-making at the concept stage, because it can become prohibitively expensive to make changes later on.

This kit describes the four main phases of inclusive concept design:

1. Manage: Review the evidence to decide ‘What should we do next?’
2. Explore: Determine ‘What are the needs?’
3. Create: Generate ideas to address ‘How can the needs be met?’
4. Evaluate: Judge and test the design concepts to determine ‘How well are the needs met?’
