Claims analysis is a technique for examining the positive and negative consequences of design features that are described in current or future scenarios of use. A "claim" is a statement of the consequences of a specific design feature or artifact on users and other stakeholders.
The criteria for determining whether claims are positive or negative for a particular scenario include:
- Attributes of the target user groups
- Theories from cognitive psychology
- Human-computer interaction (HCI) research, principles and guidelines
- Domain knowledge
- Environmental factors
