What is McCallâs Software Quality Model?
McCallâs Software Quality Model was introduced in 1977. This model is incorporated with many attributes, termed software factors, which influence software. The model distinguishes between two levels of quality attributes:
- Quality Factors
- Quality Criteria
Quality Factors: The higher-level quality attributes that can be accessed directly are called quality factors. These attributes are external. The attributes at this level are given more importance by the users and managers.
Quality Criteria: The lower or second-level quality attributes that can be accessed either subjectively or objectively are called Quality Criteria. These attributes are internal. Each quality factor has many second-level quality attributes or quality criteria.
Example: The usability quality factor is divided into operability, training, communicativeness, input/output volume, and input/output rate. This model classifies all software requirements into 11 software quality factors. The 11 factors are organized into three product quality factors: Product Operation, Product Revision, and Product Transition.
