Using software QA services, you will prevent potential bottlenecks that comprise performance issues and security vulnerabilities. As software failures may cost thousands and millions of dollars, it is crucial to focus on QA for cost savings and increased trust in your products.

2. Why should you engage QA experts from the project start?

As a rule, QA experts are involved in every stage of the software development life cycle. The task of a software QA team is to verify that each step—customer needs analysis, work planning, design, programming, testing, deployment—is performed right.

In addition, QA professionals make sure that software engineers follow best practices to deliver the highest solution quality. By engaging QA specialists from the project start, you will improve team collaboration, prevent potential issues, and increase product success chances.

3. What are the well-known examples of software failures?


In 2015, Starbucks lost millions in sales because of a major computer system failure that was caused during a daily system refresh. Stores were not able to carry out payment transactions. At some point, many coffee houses were giving drinks free of charge. As a consequence, 60% of cafes in the US and Canada were forced to close until the problem was addressed.

TSB Bank

Another example is a massive online banking outage that took place after the software upgrade in April 2018. This upgrade was planned to suspend digital banking services for one weekend only but resulted in months of disruption.

Millions of TSB clients were locked out of their bank accounts for two weeks. Furthermore, some customers were shown the information from the accounts of other people. When the new system was turned on, users also experienced issues trying to sign in.

4. How does QA allow for saving costs and maintaining reputation?

The use of software QA services allows for preventing data breaches and performance issues that may lead to significant losses. For instance, a server running the UK NATS (National Air Traffic Services) system for flight data processing failed in December 2019.

As a consequence, more than 150 flights from London airports were canceled while hundreds of flights were delayed. This way, poorly performed QA or the lack of it can result in not only huge expenditures but customer dissatisfaction, low retention rates, and harmed company reputation.

5. How will you enforce security by hiring a QA team?

The purpose of software QA services is to ensure data security and protect against various threats that involve hacker attracts, malware, and viruses. Software quality assurance engineers also prevent data breaches that may arise after product release.

It is worth noting that at Arateg, our developers also set up continuous system monitoring to instantly identify potential issues and automatically restart failed components.

6. How does QA help ensure compliance with project requirements?

Before project development, the client or software experts write a technical specification that contains the requirements to solution design, functionality, use cases, performance, and other aspects. Thanks to this document, everyone in the team has a clear understanding of how the future product is expected to look and operate, as well as what pain points it has to address.

During the software testing process, QA engineers verify that an app or website aligns with customer requirements listed in the document.

7. Does QA aim to achieve conformance with the required standards?

Yes. Software quality assurance services aim to ensure conformance with worldwide accepted standards, for example, ISO/IEC 9126, which is used to meet a variety of quality internal and external metrics. In addition, QA experts verify that a software system is compliant with the necessary industrial and security regulations.

For instance, financial technology companies have to comply with PCI DSS, ISO/IEC 27001, and GDPR. US healthcare institutions must achieve compliance with HIPAA and HITECH.

8. What is the difference between QA and software testing?

The main goal of quality assurance is to deliver performant solutions that look and behave as intended, comply with client specifications, as well as meet the necessary standards. QA professionals make sure that a software system is created properly and best development practices are used.

Software system testing is a process of detecting bugs and errors. Testers identify defects and describe them to software engineers for further debugging. Then, the product is prepared for release. In fact, testing is a part of software QA services.

9. Do I need to conduct manual or automated testing?

To find out the answer to this question, let’s have a closer look at these types of application testing. When conducting manual testing, software experts play the role of end users to find bugs and errors. Simply put, they interact with the solution to verify that it performs as intended with no defects. During this process, testers generally follow a test plan written earlier.

Automated testing allows QA specialists to reduce the time for repetitive tasks while increasing test coverage and eliminating human errors. Employing software tools and programs by testers, it is possible to save up to 30% on quality assurance services. Thanks to this, organizations can significantly cut time to market, which is essential under tight deadlines.

When building a small or medium-sized project, it is recommended to use manual testing. However, automated testing can become a magic pill if you need to implement a large-scale project when improved productivity is crucial. Additionally, automated testing can be applied to cases that are difficult to check manually.
