How to Choose the Best-fit Quality Assurance Company?

Before choosing any vendor, you have to define a clear requirement first. Clearly identifying the testing types needed for your projects, working scope, timelines, and any technologies or framework involved is essential. This first step will allow you to easily assess if the outsourcing vendor meets your needs.

When choosing an outsourcing software testing provider, decision-makers should consider several fundamental requirements. In order to help you make an informed decision, we have created a list of key considerations:

• Experience and Expertise: When choosing a provider, it is crucial to select one with a proven track record and relevant experience in executing successful testing cases, preferably in your domain. In addition, it is necessary to thoroughly review their industry knowledge, industry awards, and certifications.
• Privacy and Confidentiality: Security is a considerable concern when outsourcing IT projects to an external testing vendor. Therefore, you have to ensure that your outsourcing vendor has strict protection policies, confidentiality agreements, and any relevant certifications (e.g., ISO 27001) to protect your sensitive data and information.
• Communication and Collaboration: Effective communication between your in-house team and outsourced software testing vendor is the key to every outsourcing project’s success. Hence, you have to ensure that your vendor has the ability to provide regular updates and reports while delivering transparent and responsive communication channels.
• Staff Testing Skills and Certifications: When evaluating a potential outsource software testing team, it is imperative to assess the qualifications and skills of its members through their certifications, training, and experience. Furthermore, you must ensure that the team possesses the expertise needed to handle your project’s specific requirements.
• Scalability and Flexibility: Given the importance of flexibility in a software testing services provider, you should consider if they can adjust their testing efforts and necessary resources (staff, infrastructure, etc.) based on your project’s needs. It is crucial that you evaluate their ability to accommodate changing requirements, timelines, or project scope.
• Cost-effectiveness: Even though cost shouldn’t be the deciding factor, it’s important to make sure “you get what you paid for”. Therefore, make sure you’ve compared the cost to the value they provide, including their expertise, quality, and continual support.

Cost-effectiveness

LQA offers IT experts who can efficiently handle tasks while assuring your optimized budget by taking advantage of the cost gaps in the Vietnam outsourcing market:

• The Vietnamese government has been proactively promoting and supporting the IT industry through The National Digital Transformation Programme 2020–2025
• Vietnam’s tax incentives indirectly help foreign businesses reduce costs for IT outsourcing projects. Science, and technology businesses in Vietnam are eligible for a 4-year tax exemption and a 50% reduction in corporate income tax for the following 9 years. Additionally, software projects are eligible for VAT exemption, including outsourced software projects in Vietnam.

The Bottom Line

Software Quality Assurance (SQA) is an essential phase in every software life cycle. It helps prevent bugs, decreases development costs, and enhances performance. Many companies choose to outsource to external software testing companies, while others choose to set up their own in-house quality assurance department.

Software QA Outsourcing has its own pros and cons. However, setting up an in-house software quality testing team can present much more challenges such as costly infrastructure and resources, time-consuming recruiting and training processes, limited expertise, and scalability. That’s why many global companies now prefer outsourcing their software testing to an external vendor.

Searching for a reliable and suitable vendor of software testing services requires considerable effort and time as IT businesses are supposed to investigate vendors’ expertise, language proficiency, cultural compatibility, time zone differences, and pricing. Each provider has their advantages and disadvantages, therefore, before IT firms make the final call, dig deep into the project’s requirements to pick the right partner.
