Do you want to hit the market with an amazing app, blow your users’ socks off, and receive a high return on investment? In such a way, a partnership with a professional software testing company is a must for you.

To withstand severe competition, attract users in droves, and, what is even more important, keep them engaged, you should offer a product of first-class quality.

To help you achieve your business goals, the best London software testing agencies execute a great variety of tests in order to check all ins and outs of an application and not to leave any detail out.

In-house QA team or outsourcing? Which one to choose?

It is an indisputable truth that software testing is an essential part of the development process. However, how to get the most out of it? Is it better to set up your own QA department or outsource QA services? Let’s try to figure it out together.

In-house testing

In-house testing is a viable option for those who prefer to keep an eye on the ball in order not to miss a thing. Having your own QA department, you can personally control and manage the whole QA process. Besides, having a QA team in place, you can set up a meeting any time and handle burning issues on the spot without any delays. One more advantage of in-house testing is an opportunity to keep all the processes under the same roof and therefore provide better security conditions. Data security is extremely important these days, and it is often a key factor to opt for an in-house QA department. One more important aspect is domain expertise. By working exclusively on your projects, your in-house QA engineers are getting aware of all details of your business and therefore perfectly know the main challenges, tendencies, and goals.

As for disadvantages, the main one is heavy expenses related to recruitment, labor costs, license fees, worksite arrangement, and many others. Even if your company can afford to set up its own QA department, it makes sense only if you are going to make software testing one of your main business activities.

Software testing outsourcing

Outsourcing of QA services is getting more and more popular. Thousands of companies from different corners of the world have already assured of its benefits. First of all, it is a fire sure way to save a lot of money, especially if you collaborate with an offshore outsourcing QA company which rates are much lower. Besides, there is no need to waste a lot of time, effort, and money on staff recruitment, equipment procurement, renting, personnel training, etc. An outsourced team can proceed to your product testing almost immediately because outsourcing QA companies have vast human resources and all equipment, software, and tools at their disposal. Your outsourced QA team can be easily and quickly ramped up if it is needed. One more important merit of outsourcing software testing firms is broad experience. They regularly work on applications of different sizes, various complexity degrees, and from the most diverse domains. As a result, you can get access to the talent pool with indeed rich experience. Trying to keep their clients well-informed, professional outsourcing software testing companies regularly submit reports on current product quality and work progress. Frequent online meetings are also a norm if you work with an outsourcing company. So, if you are not a control freak and you are not bound by strict security measures, outsourcing is a great option that can offer you high-quality and fairly priced software testing services.

There are plenty of outsourcing software testing companies in London. In the Superbcompanies list you can find the best ones. So do not waste your time for further search - look through the hand-picked list of London software testing firms and choose the one to entrust your software to.
