In a highly competitive business world with increasingly demanding customers, companies start to care about quality even more. For a long time, the software development process has followed the traditional approach of the waterfall model with QA activities taking place at the end of the development process, just before the product launch. The popularity of the agile model in software development led to the agile approach to QA, which translated into a more intensive collaboration between development and QA teams. It is clear that developers are those who write the code, but what do QA specialists do?

Who is a QA engineer?

A QA engineer is a specialist whose primary goal is to ensure the highest quality of the software before its release. QA teams generally play the role of “client agents” — they represent the demands of the potential customers within the company and help developers to understand the target audience better. People often confuse QA engineers with testers (as they all perform the tests), but the scope of QAs responsibilities is much wider. QA engineers, unlike testers, who check particular parts of the program at a particular time, oversee the product creation process from start to finish. Depending on the stage of the product development they:

  • help to set the project requirements;
  • identify the deficiencies of the product;
  • perform different types of tests;
  • share updates about the level of the product quality;
  • look for the solutions to the identified issues;
  • collaborate with the development team;
  • write and/or review the code;
  • identify QA process bottlenecks;
  • collect data to set the criteria of the product quality.

Why QA is so important

Before we get to the question of QA importance lets first find out what the quality of the software is. The term software quality refers to the suitability of a product, in other words, whether the product meets the established requirements. There are several criteria for the software quality. They are: correctness (does the program deliver the desired functionalities?), readability (is the program code legible and understandable?), efficiency (does the program use the resources optimally?).

Quality assurance is the set of activities to ensure that a company is providing a product or solution that runs reliably, smoothly and without errors. QA encompasses much more than detecting as many bugs as possible. Rather, the task of the QA team is to support web developers in delivering products on time and identify any problems that could impair the successful operation of the software or jeopardize its user-friendliness. Another important goal of the QA is to optimize the process of product delivery.

Testing cost and QA cost make even more sense for companies building big software projects. For the complex products with millions lines of code, there are no experts who understand the entire system well. And only QA specialists — capable to see the big picture — can identify the problems in it.

A good QA not only increases the reliability of the product and improves the development processes, but also helps companies to save costs. With the right software testing pricing models and skilled performers, you can achieve this goal pretty easily.

How QA saves you money

Young companies that are just testing the pricing models think that QA services are too pricey for them. In reality, though, software QA and testing costs can be reasonable. Moreover, integrating quality assurance into the development process helps you to cut the internal costs. Here are the main ways in which QA does this:

  • Lower failure rates. QA allows you to weed out all the defects and inconsistencies of your software product. Fixing the bugs after the    program is released is much more expensive than doing it during the development stage. This makes the cost of software testing absolutely justified.
  • Better reputation. If your product is of the highest quality you will be able to save money on customer claims within the warranty period. QA is also aimed at ensuring that your program is safe. A more secure product, in turn, strengthens your good reputation and the clients’ perception of your company as a reliable one.
  • Preventative measures. QA can also include checking the codebase to determine whether there is a code that violates the rights of other firms. This can prevent major financial damage in the long run.
  • Higher efficiency. Because QA is focused on high-quality, it increases the efficiency of the development process that will bring benefits (including decreased costs) for the future projects of your company.


Quality assurance is no longer a story about catching bugs, but rather about the streamlining of business processes and ensuring great customer experience. One of the most famous software testing quotes says: “Excellent testing is quite hard to do”. Hard doesn’t mean impossible, though. With an experienced QA company, building market-ready products became much easier. If you want to perfect your software, smooth the delivery process and reduce the costs – contact us.
