Explicitly defining the vision includes:
1. Confirm the business objectives
- what benefits does the project aim to deliver ?
- what are the initial and continuing costs ?
- if it is a commercial proposition, what is the business model ?
- what are the critical success factors ?
2. Identify and involve stakeholders
There may be many different people or groups with a stake in the product design and use: sponsors, project management, marketing, technical managers, designers, content providers, content managers, consumer groups, customer organisations, end-users, support service providers, disability groups, usability professionals, etc. Identify them and gain appropriate involvement.
3. Develop the initial concept
- understand the high level vision, product goals and rationale
- develop scenarios of use
- create some initial design representations.
4. Plan user validation
- choose and scope out user-centred activities
- outline validation scenario and focus of the assessment
5. Subsequently plan in detail
- draw on analysis of user requirements, users, tasks and context of use
- define quality factors, how to measure them, and quality criteria.
