Type of Guidance
Principles and general recommendations.
- General guidance.
This part of ISO 9241 presents a set of usability heuristics that applies to the interaction of people and information systems (the heuristics are based on an earlier German standard). The standard refers to this interaction as a “dialogue” and describes seven “dialogue principles”. These general principles span the specific dialogue techniques that are discussed in parts 13-17 of ISO 9241. The seven principles are: suitability for the task (the dialogue should be suitable for the user’s task and skill level); self-descriptiveness (the dialogue should make it clear what the user should do next); controllability (the user should be able to control the pace and sequence of the interaction); conformity with user expectations (it should be consistent); error tolerance (the dialogue should be forgiving); suitability for individualisation (the dialogue should be able to be customised to suit the user); and suitability for learning (the dialogue should support learning). The standard describes applications and examples of the dialogue principles. It has one annex (a short bibliography). This part of ISO 9241 used to be known as ISO 9241 part 10, but has now been renumbered under ISO's revision and restructuring programme.
