Frequently asked questions

Aren’t QA engineering & software testing the same thing?

At root, both software quality assurance and testing aim at solution improvement. Yet, software testing focuses on code sanity from a purely technical standpoint, while QA engineering is a means for efficiency enhancement within the overall development process.

Doesn’t it affect the end product’s efficiency if you keep software quality assurance and development separate?

If you entrust your quality assurance services to a highly-qualified QA testing contractor, it would actually be quite the opposite. An experienced certified team can examine your project from a professional perspective, enabling objective insight and coming up with value-driven improvements.

Can you pick my existing project up from another vendor?

Definitely. Not only do we provide software testing services as an integral part of all our engineering projects, but we also offer team extension and emergency solution-fixing.
