Quality Assurance Services

What Is Software Quality Assurance?

The software quality assurance process is a comprehensive evaluation of the product, encompassing a range of activities. QA specialists will perform a series of steps, including automated and manual testing, to assess features such as:

  • Performance
  • Load the software can accommodate
  • User experience
  • Functionality
  • Security

QA specialists do detect the presence of bugs, but it is a misconception to say that this is all they do. Moreover, it’s important to understand that the QA process cannot guarantee the absence of bugs altogether. Instead, it can identify and resolve as many as possible.

Quality Assurance Service vs. Quality Control Service

Quality assurance service is an ongoing, comprehensive process that is carried out throughout the SDLC. Developers and QA specialists work together to identify and resolve defects while simultaneously assessing other aspects and features of the software. This is because it is much easier to fix problems earlier on in the process than to leave them until the last phase.

QA differs from quality control (QC) in that the latter is that ultimate step—something the team saves until the end. QC is essentially a final series of tests that are used to detect problems that you haven’t spotted previously. QC falls under the umbrella of QA, but it is just one stage in a multifaceted process—the one at which you perform a final inspection of the software.

Benefits of Quality Assurance

The QA process results in numerous benefits:

  1. Product quality. Creating quality products is essential for companies to earn revenue, as well as customer satisfaction and loyalty. Quality products also build the reputation of companies to bring in more business. 
  2. Problem prevention. Just as important as ensuring product quality is ensuring the absence of problems. Such issues can cost companies considerable time, money, and hits to their reputations. 
  3. Cost savings. When done right, the QA process can save companies money by identifying problems before they become too big to solve cost-effectively. In doing so, the process saves time as well, which can help companies more quickly move on to the next project.
  4. Security. Software products that lack security can cause big problems when user data becomes compromised. The QA process includes checks to ensure a high level of security while reducing potential vulnerabilities.  
  5. Engineer improvement. Through the QA process, software engineers learn from their mistakes as QA professionals check their work and identify issues.

Quality Assurance Testing Types

Broadly, QA testing falls into 3 categories:

  • White box testing: The tester examines the inner workings and infrastructure of the software, performing a thorough evaluation of how the components and features function together and relate to one another. Testers know how the software was developed.
  • Gray box testing: Testers look for defects that may result from using the features and tools incorrectly. A blend of white and black box testing, gray box testing means the testers do not have the full picture of how the product was developed, although they have partial knowledge.
  • Black box testing: Testers have no knowledge of how the software was coded or built. Instead, they are going in blind, much like an actual user who will access the software without understanding how it was created.

There are also different approaches to QA testing: manual, automatic, and a blend of the two. Manual testing involves a human performing the evaluation without interference from a machine. Automatic testing means a professional will use a script and automation tools to have a machine run the test. The in-between approach means that a professional creates the testing environment, but the test itself runs without human intervention.

What Does a Quality Assurance Services Company Do?

The QA team will work closely with the rest of the software development team to create a comprehensive, thorough testing plan. While the process will look different depending on the specific requirements and product, generally speaking, it follows these steps.

  • Review of the requirements and quality parameters for the software
  • Creation of a plan with objectives, tools, and professionals needed
  • Project management of the QA process throughout
  • Careful monitoring by all QA professionals involved
  • Reporting on defects identified
  • Communication with the software developers to address any defects
  • Enforcement of protocols
  • Automated and/or manual testing of different types

The testing itself takes several different forms, and the team will determine which types are important for the software at hand. Examples of tests include:

  • Performance
  • Usability
  • End to end
  • System
  • Security
  • Acceptance
  • Load
  • Integration

Quality Assurance Processes

QA is performed according to a series of steps, as follows: 

  1. Execute a formal technical review to discuss quality requirements for the software. 
  2. Develop a testing plan that includes a goal, a QA approach, activities, tools, and staff. 
  3. Create checkpoints to review how the process is going. 
  4. Perform multiple types of testing to ensure the best quality. 
  5. Enforce process adherence by ensuring the correct steps are taken during the development process. 
  6. Control change by validating change requests. 
  7. Measure the impact of changes made by the development team to fix defects. 
  8. Perform audits to ensure the QA process has been followed closely. 

Maintain records and reports, including test results, audit results, review reports, and change requests, so you can share QA information with stakeholders.
