Study Notes
- Software quality can guarantee certain user expectations
- Software is never perfect, but should aim for best possible quality
- Software quality is different from other industrial products due to its abstract nature
- Software is developed, not manufactured, so errors occur in design phase
- Software does not deteriorate over time
- Maintenance problems were present from the beginning, not generated later
- Software with errors is assumed to be inevitable
- Quality should be considered in all stages of software evolution
- Software quality is not restricted by physical laws or manufacturing processes
- Cost and errors in software development are mainly generated in design phase, not production.
- McCall's classic quality model was developed in 1977 for the US Air Force.
- It is one of the most widely used software quality management models.
- The model aims to bridge the gap between users and developers by focusing on quality factors.
- There are three types of quality characteristics: factors, criteria, and metrics.
- The model describes 11 quality factors, 23 criteria, and 41 metrics.
- Quality factors represent the user's perspective and refer to the software's current behavior and ease of use.
- The model has served as a base for other quality models.
- The model seeks to reduce the gap between users and developers by prioritizing their respective needs.
- McCall's model is organized around external and internal views of software quality.
- The model's metrics provide a scale and method for measurement.
- The CMM model focuses on software process improvement.
- It has 5 levels of maturity based on process capability.
- Each level has a set of key process areas that must be satisfied to progress to the next level.
- Metrics are used to determine the quality of each key area.
- Each key area is organized into 5 common characteristics.
- The first characteristic is commitment, which relates to organizational policies and leadership.
- The second characteristic is capability, which describes the necessary preconditions for successful software development.
- The third characteristic is activities, which are the specific tasks and procedures required for software development.
- The fourth characteristic is measurement, which involves collecting and analyzing data to improve the software development process.
- The fifth characteristic is verification, which ensures that the software is developed according to the specified requirements.
- CMM (Capability Maturity Model) lacked integration between different models
- This led to increased cost for implementation
- CMMI (Capability Maturity Model Integration) was developed to address this issue
- CMMI provides a simple framework for process improvement
- It contains adaptable models for different areas of knowledge
- CMMI includes evaluation methods and training material
- The initial objective of CMM was to obtain quality products within time and cost constraints
- CMMI applies principles throughout the engineering life cycle, not just software development
- CMMI maintains compatibility with the SPICE model
- CMMI can be considered an extension of CMM-SW with added areas.
