Study Notes
Quality Assurance
- Quality Assurance (QA) helps prevent product defects by defining standards and procedures.
- QA methods include:
- Failure testing: testing a product to determine its breaking point.
- Statistical process control (SPC): a methodology based on objective data and analysis.
- Total quality management (TQM): a methodology that applies quantitative methods for continuous improvement.
Software Quality Assurance
- Software Quality Assurance (SQA) systematically finds patterns and takes actions to improve development cycles.
- SQA strategies include:
- Capability Maturity Model Integration (CMMI): a performance improvement-focused SQA model.
- Without SQA, disadvantages arise, such as product bugs and market dissatisfaction.
Quality Assurance Process
- The QA process cycle is called the PDCA cycle or Deming cycle, which consists of:
- Plan: establishing process objectives and determining required processes.
- Do: developing and testing processes.
- Check: monitoring processes and modifying them to meet objectives.
- Act: implementing actions to achieve improvements.
Quality Control vs Quality Assurance
- Quality Assurance (QA) focuses on providing confidence that quality requirements will be fulfilled.
- Quality Control (QC) focuses on fulfilling quality requirements.
- QA examines processes, while QC examines products or services.
Quality Assurance Activities
- Examples of QA activities include:
- Quality Audit
- Defining Process
- Tool Identification and selection
- Training of Quality Standards and Processes
- Examples of QC activities include:
- Walkthrough
- Testing
- Inspection
- Checkpoint review
Industry Perspectives on QA and QC
- For service organizations, quality control may be foreign because there is no tangible product to inspect.
- Quality assurance in service organizations may include quality control of products involved in providing the service.
Best Practices and Functions of Quality Assurance
- Best practices for QA include:
- Creating a robust testing environment
- Selecting release criteria carefully
- Applying automated testing to high-risk areas
- QA involves creating components with high cohesion and low coupling, making them reusable.
- Components provide interfaces for communication among different components.
Reuse Process
- Two methods for reusing software components include:
- Keeping requirements same and adjusting components
- Keeping components same and modifying requirements
- Reuse can be done at various levels, including application, component, and module levels.
