Quality Assurance & Quality Control (QAQC): Why Does It Matter in 2022?

What Is Quality Assurance?

  • A heavy emphasis on quality management
  • A sophisticated, multi-phase testing strategy (although testing will fall primarily beneath the umbrella of quality control)
  • Detailed reporting and measurement mechanisms for clearly defined standards
  • Comprehensive reviews of technical elements
  • Modern software engineering solutions, methodologies, and technologies
  • Quality assurance plan

Benefits of Software Quality Assurance for Businesses

  • Saves Money — Errors and breakdowns can be expensive, requiring further investment in resources, labor, and time. Quality assurance works as an insurance policy for the development process; investing meaningfully upfront in oversight and prevention is cheaper than the cost of breakdowns.
  • Prevents Breakdowns & Catastrophic Failure — Catastrophic breakdowns are damaging in numerous ways, from additional costs and lost time to reputational damage.
  • Boosts Customer Confidence — The trust of your customers is hard to earn and easy to lose. Quality assurance helps you preserve the goodwill you’ve built for your organization.
  • Increases Product Safety — Software bugs can be significant cyber security risks. Software QAQC helps to ensure you’ve taken the safety of your clients’ data seriously.
  • Enhances User Experience — Beyond the risk of catastrophic breakdowns, software quality assurance helps to ensure the project delivers a seamless UX.
  • Saves Time — Errors take far less time to correct in the design stage than after the product has gone to market. Quality assurance implements and oversees process metrics from the outset that minimize the risk of time-consuming repairs and revisions.
  • Reduces Maintenance Costs & Increases Profit — All of the above benefits combine to deliver higher profits for the project and safeguard those profits with reduced maintenance costs, as fewer issues will arise later that had eluded developers in the design stage
  • Promotes Organizational Efficiency & Productivity — Quality assurance helps to build a culture in software development organizations of efficiency, productivity, and accountability. This can have a ripple effect that improves the company’s overall performance and the standard of its work.

What Is Software Quality Control?

  • Coding
  • Deployment
  • Design
  • Requirements
  • Test cases
  • Test plans

How Quality Control Benefits Businesses

  • Increased productivity for developers — Developers spend, cumulatively, less time on repairs and revisions when they detect bugs earlier.
  • Higher Quality Products — The central benefit and ambition of QC for software projects.
  • Decreased revision costs — Quality control minimizes compound defects and the risk of catastrophic failure by detecting defects earlier across the full project.
  • Increased developer confidence — Developers will have a more holistic perspective on the software’s capabilities and will have safeguarded against common defects.
  • Increased developer credibility — Developers enjoy greater credibility when software projects exhibit fewer defects after going to market.

Relationship Between QA, QC, and Testing

An Example of Software QAQC in Action

How Does Quality Assurance Compare to Quality Control?

QA vs QC: The Basics

  • Approaches quality standards proactively.
  • Verifies the quality of the software.
  • The developers’ processes are the focal point.
  • The entire team is QA personnel
  • QA oversees everything, from the planning stages to product control.
  • Enacts and oversees a high standard of operations to ensure a high standard for the final product.
  • Approaches quality standards reactively.
  • Validates the quality of the software.
  • The product itself is the focal point.
  • The testing team is QC personnel.
  • QC applies to testing, mostly during the control stages.
  • Fulfills the testing necessary to ensure the requested quality for the product.

Detailed Comparison

  • Processes are planned, realized, and overseen to prevent defects before the finished product reaches the market.
  • Defines and establishes quality metrics that developers must adhere to throughout the software development life cycle.
  • Focuses on what developers have delivered, as well as how they delivered it.
  • In an agile development environment, QA begins in preliminary production and is in place in time to apply to the full process.
  • The QA process includes:
    Change control
    Investigative procedures
    Training and development for developers and testers
  • Quality assurance involves everyone participating in the project, as everyone operates within the metrics and procedures defined by QA across the full project.
  • Depends on QC to ensure that the success metrics established by QA at the outset have been followed.
  • Applies SQC (Statistical Quality Control), considered a component of QA methodologies.
  • Processes are planned and implemented to diagnose bugs after they’ve occurred, allowing the development team an opportunity to correct them.
  • The testing team bears sole responsibility for quality control, which only involves developers again after diagnosing any concerns.
  • Depends on QA to produce sound benchmarks against which they may measure test cases.
  • Applies SPC (Statistical Process Control), considered a component of QC methodologies.
  • The QC process includes:
    Batch inspection
    Functional & non-functional testing
    Lab testing
    Program execution
    Quality validation
  • Quality control cannot occur until after the primary development phases are complete, as QC applies to the product rather than the process.
  • Assesses developers’ output to determine whether they have met the project’s success metrics.
  • Uses a testing regiment to ensure developers met the defined quality metrics.

What Do QA & QC Have in Common?

  • Both are considered parts of the larger quality management apparatus and overseen by the same quality management apparatus.
  • Project stakeholders hold both in high regard because they signify value and efficiency across the entire software development life cycle.
  • They’re both the results of deliberate and successful planning, as well as a commitment to streamlined, data-driven workflow.
  • Both rely on standards that organize the project’s policies and procedures. Neither leans heavily on improvisation or creativity, opting instead for strict adherence to clearly defined benchmarks for both the process and the product.
  • Both save time and money across the delivery of the project. However,
  • …both also require an investment of time and money upfront. Software QAQC is the unofficial insurance policy protecting the project. It represents the deliberation and accountability that will be crucial to the project’s success.
