What to Look For When Choosing a Software Testing Company
This is indeed crucial to make the right choice of a software development company. No need to explain that your partner should be trustworthy and should provide professional QA services. So, here are a few things that deserve your attention even when you choose from the best software testing companies:
Engagement Models
While reviewing a company profile, pay attention to the engagement models it offers. Make sure that the one you need is provided. Thus, the most widely used models are Dedicated Team, Time&Material, Fixed Price, Staff Augmentation, and Hybrid Model.
In-Depth Knowledge and Expertise in Software Testing
A software testing company should be able to provide you with experienced QA specialists who can handle all QA-related issues and set up a QA process from scratch if needed.
Domain Expertise
Domain expertise is as important as technical expertise. It lets a QA team clearly understand software behavior and end users’ needs. It is especially crucial when it comes to testing healthcare, fintech, pharmaceuticals, insurance, and retail apps. Domain expertise significantly contributes to the establishment of an appropriate QA process. So check whether a potential partner has already tested software similar to yours.
Awards and Certifications
Professionalism never has gone unnoticed. Awards, accolades, and certificates demonstrate the competency and leadership of a software testing company. Have a look at those that your partner has already held.
Communication Model
Make sure that a company is open to communication, responsive, and client-focused. Efficient communication lies at the heart of every successful project, therefore your partner should be friendly, supportive, and straightforward.
Testimonials
It makes sense to take time to check clients’ feedback on the company’s services. Testimonials published on an official website, social nets, and independent review platforms can help you to form the right opinion about the potential partner.
Price Policy
Discuss the financial aspects of your partnership in advance. Make sure that a company offers a transparent price policy without hidden charges. Moreover, it is worth remembering that a high price is not always a guarantee of high quality, while too low rates also raise suspicion.
Team Location
Offshore outsourcing comes with great benefits especially when it comes to service fees. Still, choosing a software testing company, consider its location as it affects not only the price but also communication. A time difference, cultural differences, and a language barrier can cause problems.
Conclusion
Your search for a reliable provider of software testing services can be rather time-incentive and effort-consuming. Still, that is worth it. Your QA partner should be highly-professional, committed, and reliable. We believe that our software testing companies list as well as a set of important criteria will help you to find a perfect QA partner.
