Quality control (QC) is concerned with the end product and seeks to ensure that it is not defective or damaged before reaching the customer. The defects that quality control is interested in are likely derived from faulty manufacturing processes rather than inherently ineffective processes (as you would typically see with quality assurance). QC is a reactive process employed after the product has been created to verify its quality. At a surface level, it involves several stages for effective project management.

• Set Checkpoints. The team sets up specific checkpoints to evaluate the project’s activities during each stage. Checkpoints ensure regular quality inspection throughout the life cycle.
• Deploy Software Engineering Techniques. Software engineering techniques help software designers achieve high-quality specifications. For example, designers may gather information using FAST (Functional Analysis System Technique) or interviews. Once the developers gather the needed info, they can create project estimation using techniques such as Functional Point (FP), Source Line of Codes (SLOC), or Work Breakdown Structure (WBS).
• Conduct Formal Technical Reviews. FTRs evaluate the design and quality of the product’s prototype. These reviews involve meeting with the technical staff to talk about the software’s actual quality requirements and the prototype’s design quality.
• Include a Multi-Testing Strategy. In other words, don’t rely on a single testing approach. Instead, test the product from different angles with multiple testing strategies.
• Enforce Process Adherence. Designers must conform to the established processes and employ only defined procedures.
• Control Changes. Designers use a combination of automated tools and manual procedures to control changes. This stage includes evaluating the nature of any changes, validating change requests, and controlling the effects of the changes.
• Measure Change Impact. If the product has a defect, the team fixes it. As a result, something in the product has now changed. The QA team must determine how this change impacts the overall product and if the change is compatible with the rest of the project.
• Perform Software Quality Assurance Audits. This audit compares the whole Software Development Life Cycle (SDLC) process to the established procedure. The audit also reveals non-compliance issues and ensures that the proper parties act on any reported QA issues.
• Maintain Reports and Records. Documentation is key to any quality assurance endeavour. Documentation includes audit results, change requests, test results, and review reports. The team should share this information with the stakeholders.
• Keep Good Relations. Ensure that the QA and development teams cooperate and get along. Often, these teams develop cliquish or superior attitudes, and that sort of behaviour must be discouraged.

Overall, Software quality assurance helps organizations ensure that their application is efficient, secure, and trustworthy—customer satisfaction. Your software application has to fulfil all the needs to satisfy the customers. It has to work smoothly without any malfunctions.
