Study Notes

Software Quality

  • Crosby's perspective on software quality: delivering everything specified in the requirements document equates to quality software.
  • Juran's perspective: satisfying client needs, wants, and expectations, even if not explicitly stated in the requirements.
  • Client vs. users: clients are responsible for acquiring software; users are those who ultimately use it.
  • User needs: functionalities, performance, efficiency, accurate results, reliability, and usability.
  • Client priorities: cost and deadlines, with a focus on the best solution at the best price.

Factors Affecting Client Requirements

  • Expressed Requirements: Stem from user needs, and include:
    • Unfamiliarity with true requirements
    • Instability of requirements
    • Different viewpoints of ordering party and users
    • Incomplete specifications
    • Lack of standards
    • Inadequate communication
  • Specified Requirements: Originate from software documents, and include:
    • Insufficient quality control
    • Inappropriate management and production methods
    • Insufficient quality control techniques
  • Achieved Requirements: Derived from documents and product code, and include:
    • Insufficient test quality
    • Insufficient document control techniques

Software Quality Assurance (SQA)

  • SQA is a set of activities to define and assess software process adequacy.
  • SQA aims for confidence that software meets intended purposes.
  • SQA function should be objective and independent.
  • SQA implementation reduces risks of unmet stakeholder needs.

Elements of SQA

  • Planning quality aspects of products/services.
  • Systemic quality activities throughout software lifecycle.
  • Quality system establishing quality policy and continuous improvement.Demonstrating quality levels to instill confidence.Demonstrating defined quality requirements are met.

Software Quality Assurance Through Prototyping

  • Prototyping allows engineers and users to "test drive" software.
  • Understanding technical aspects and feasibility of a system.
  • Prototyping can clarify requirements and reveal critical design considerations.
  • Prototyping can identify and fix weaknesses in software design.

Advantages of Prototyping

  • Users actively involved in development.
  • Better understanding of the system by end-users.
  • Early error detection leading to better solutions.
  • Quick identification of missing/confusing functions.

  • Incomplete problem analysis.

Models of Prototyping

  • Prototyping is an iterative, trial-and-error process.
  • Six SDLC phases:
    • Requirements Gathering and Analysis
    • Quick Design
    • Build a Prototype
    • Initial User Evaluation
    • Refining the Prototype
    • Implementation and Maintenance

Code Reviews and Inspections

  • Code reviews are used to reduce cost, find and remove defects, and improve software quality.

    • Walkthroughs
    • Code reviews
    • Inspections
  • Inspection roles:
    • Moderator
    • Author
    • Reader
    • Reviewers
    • Recorder
    • Managers

Software Testing

  • Verifying and validating software against requirements.
  • Different testing types and objectives:
    • Manual Testing: Tester acts as end-user using plans, test cases, or scenarios.
    • Automation Testing: Utilizes scripts and automated software.
    • Dynamic Testing: Tests software behavior by interacting with units.
      • Black-box: Input/output with unknown details.
      • White-box: Input/output with known details.
    • Static Testing: Analyzes code without execution.
    • Integration Testing: Combines units/modules.
    • System Testing: Overall system evaluation.
    • User Acceptance Testing: Stakeholder validation.
    • Regression Testing: Ensures changes don't introduce new errors.
    • Smoke Testing: Preliminary testing for basic functionalities.
    • Alpha Testing: In-house testing before release to customers.
    • Beta Testing: Customer testing before launch.
    • Stress Testing: Tests the system under loads.
    • Performance Testing: Measures responsiveness and stability.
    • Object-Oriented Testing: Tests object-oriented software.

Software Testing - Process Steps

  • Planning & Control
  • Analysis & Design
  • Implementation & Execution
  • Evaluating Exit Criteria & Reporting
  • Test Closure Activities

Software Development and Deployment Tools

  • Software deployment involves steps, processes, and activities for making software available.
