In detail
Definition and scope
Context of use is the physical and temporal conditions in which the task happens. It covers the environment, device, time available and interruptions. The question is not only who performs a task, but under what conditions it happens.
Use the context of use glossary entry as a vocabulary reference. Keep the definition tied to the task and its conditions, rather than treating it as a general description of the customer.
Where it matters in practice
The guide provides a context of use grid with six rows: posture, device, lighting, noise, time available and frequency of interruption. Each row eliminates design choices before assessment of the interface.
Its example combines gloves, direct sunlight and a session under a minute. Those conditions eliminate small targets, soft contrast and long menus before aesthetic judgement. For a product decision, use the grid to identify which choices the task conditions rule out.
Neighbouring terms and CPM-E preparation
User identifies whoever performs the task. Buyer identifies whoever signs the contract and answers for the budget. Operator identifies whoever sustains the product. These terms describe roles, not the physical and temporal conditions of use.
Customer profile describes a group by observed behaviour for decision-making. Customer path describes the sequence of stages, measured by loss at each transition. Keep these distinct: roles identify who, profile describes behaviour, path identifies stages, and context identifies task conditions.
When preparing for the CPM-E certification, practise applying these distinctions to decisions. The guide emphasises developing judgement, rather than memorising definitions alone.
