Recommended methods: 2. Analyse context of use
To collect and agree detailed information about:
- Who are the intended users and what are their tasks? (Why will they use the system? What is their experience and expertise?)
- What are the technical and environmental constraints? (What types of hardware will be used in what organisational, technical and physical environments?)
- Ensure that all factors that relate to use of the system are identified before design work starts.
- Provide a basis for designing later usability tests
Arrange a half-day meeting. Invite stakeholders who have knowledge about the intended users and usage. This may include:
- project manager
- user representative(s)
The first two are key areas. You will also need a facilitator and a person to record the information provided during the meeting.
To obtain information on the context of use, a detailed checklist will be needed (see below).
Before the meeting
- Provide all participants with a copy of the context of use checklist.
At the meeting
Discuss and fill in each item on the context checklist. Try to obtain consensus where there is uncertainty or disagreement. If information is missing, agree how this can be obtained. Avoid prolonged discussion of minor issues.
After the meeting
Obtain any missing information. If the information is not easily available, arrange a field study to observe users in their work environment.
Circulate to all participants a summary of the conclusions, and the filled in checklist.

- the Baseline checklist
- books which explain how instructional systems can be analysed in detail
When using a detailed checklist, to avoid prolonging the meeting it is important to fill in advance any items that are not contentious.
If it is impossible to arrange a meeting, the information can be gathered by interviewing the stakeholders. This has the disadvantage that there is no opportunity to establish consensus on, and commitment to, the usage characteristics.
For simpler systems, the context information can be collected as part of the stakeholder meeting, using a less structured process.
Generate scenarios to provide examples of usage as an input to design.
