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.
