    Study Notes

    Software Quality Engineering - Lecture 1 Notes

    • Software Quality Engineering (SQE): The process of implementing quality checks throughout the entire development cycle to ensure high-quality software

    • Goal of SQE: To ensure product quality from the beginning, minimizing defects and improving the process

    • Definition of Quality: IEEE defines quality as the degree to which a system, component, or process meets:

      • Specified requirements
      • Customer or user needs and expectations

    • How Quality is Perceived (David Garvin):

      • Transcendental: Quality can be recognized but not defined
      • User: Quality is fitness for purpose or customer satisfaction
      • Manufacturing: Quality is conformance to specifications
      • Product: Quality is tied to inherent product characteristics
      • Value-Based: Quality depends on the amount a customer is willing to pay

    • Arriving at Definition of Quality:

      • User View: Quality is fulfillment of customer needs and achieving customer satisfaction (held by Juran). A deficiency of this view is that customer responsibility for details of specifications is unclear. Customer needs may change during development.
      • Manufacturing View: Quality is conformance to specifications (held by Crosby and Standards Organizations). A deficiency is specifications may not consider customer needs. Quality products might not address customer problems

    • Definition of Software Quality:

      • Software quality is the fitness for use of the software product. (Summary of opinions of Humphrey, Denning and Dromey)

    • What Quality is Composed of:

      • Quality Attribute: The basic building block on which fitness for use is based. Features (property, attribute) of the product, materials, and process needed for fitness of use

    • Software Quality Assurance (SQA):

      • A planned, systematic pattern of actions to achieve confidence in product conformance to technical requirements (IEEE)
      • Unlike hardware, software quality stays constant. Software quality assurance is a systematic process to improve product quality.
      • SQA involves both process and product assurance to assure that software projects fulfill their quality goals.

    • SQA Activities

      • Quality Control (Downstream): Post-implementation testing to ensure the product matches specifications
      • Quality Control (Upstream): Occasional/systematic checks during development to determine conformance to standards. This includes reviews and inspections

    • Process Quality:

      • Quality of a product is determined by quality of the process used for development and maintenance

    • Software Quality Engineering (SQE) Activity (The Envelope Activity):

      • Ensures proper procedures are applied throughout, continuously checking product quality and evaluating quality at the end of development, evaluating process quality

    • Primary goals of software quality engineering:

      • Process control and oversight.
      • Implementing standards and metrics
      • Data collection and analysis
      • Test development
      • Identification of issues and solutions
      • Follow-up actions

    • Software Practices for Quality Engineering:

      • Functional Testing: Evaluating user interfaces (UI) and APIs to ensure specifications are met
      • Peer Review: Assessing source code for efficiency and logic, promoting collaboration, and addressing clear communication of programming ideas
      • Static Code Analysis: Using automated tools to perform analysis of code based on predefined standards to identify quality issues
      • Unit Testing: Checking code units (components, methods, classes) against inputs to ensure validity
      • User Performance Testing: Evaluating the speed of a product in different environments to ensure user experience meets quality standards.
