Study Notes
McCall's Classic Model for Software Quality Factors
- McCall's factor model categorizes software quality requirements into 11 factors.
- Factors are grouped into three main categories: Product Operation, Product Revision, and Product Transition.
Product Operation Factors
- Correctness: Relates to the accuracy of software outputs (e.g., querying customer balances).
- Reliability: Concerns the ability of the system to perform under various conditions without failure.
- Efficiency: Involves the management of hardware resources required for software operations, ensuring optimal performance.
- Integrity: Addresses risks of unauthorized access and potential harm to the software system.
- Usability: Measures the training and support needs for users to effectively operate the software.
Product Revision Factors
- Focus on requirements affecting software maintenance activities.
- Includes essential factors for efficient updates and modifications to software systems.
Product Transition Factors
- Pertains to how software adapts to different environments and interacts with other systems.
- Key factors include:
- Portability: Ability of software to operate across varied hardware and operating systems.
- Reusability: Encompasses two aspects: using existing software in new projects and designing new software for future reuse.
- Interoperability: Ensures compatibility with other software systems and the creation of functional interfaces.
ISO/IEC 25010 Model
- Developed by an international professional team to enhance software quality assessment.
- Features eight key factors:
- Functional Suitability: Ability to meet stated or implied customer needs.
- Performance Efficiency: Relates to the required hardware resources to execute tasks, similar to McCall's efficiency.
- Compatibility: Refers to the ease of information exchange between software components.
Comparison Between Models
- Several factors from ISO/IEC 25010 align with those in McCall's model, indicating consistent priorities in software quality assessment across frameworks.
