What is professional outsourcing of software testing?

Outsourcing software testing is the outsourcing of certain testing activities to a specialized service provider. The type and scope of the tasks to be outsourced can be defined individually. The service provider assumes responsibility for the project to a scalable extent, as required.

What are the benefits of software test outsourcing?

  • Maximizing productivity and software quality

A service provider specializing in quality assurance and testing has an experienced and optimized approach, which enables the most efficient completion of testing tasks. The systematic, structured test methodology also ensures high software quality.

  • Flexible and fast compensation of capacity bottlenecks

Even if changes or delays postpone planned release dates, a professional test service provider can react flexibly and adapt its test work to changed schedules at short notice.

The service provider can pause in the event of major delays and, on the other hand, carry out the associated tests as soon as a new version is available, thus providing rapid feedback to the development team. This is because both the personnel resources and the infrastructural requirements are flexibly available at all times. Outsourcing therefore helps to alleviate the criticality of time in software projects without having to compromise on product quality.

  • Tackling the shortage of skilled workers

Outsourcing makes it possible to cover personnel requirements quickly and economically in order to operate successfully in a highly competitive environment, especially in times of skills shortages. In addition, outsourcing test tasks can help internal department employees, for example, to focus on their main tasks.

A key objective of the current work is to continuously increase test coverage and test efficiency by further expanding test automation."


"The introduced test automation is considered a comprehensive success. The integrated code of the software teams is of a higher quality than before and there is comprehensive trust in the automated smoke tests. The framework is not only considered to be very structured, but is also being introduced in an increasing number of projects - even outside Germany. Automation efforts have decreased, test productivity has demonstrably increased and the goals of the automation investment have been fully achieved from the client's perspective."

Which testing services can you outsource to imbus?

As part of outsourcing to imbus, various service components from the field of software quality assurance and testing can be put together individually and flexibly as required. In addition to functional testing, we offer service modules in the areas of IT security, digital accessibility and load and performance.

Functional testing requires the sustainable development of customer-specific knowledge about the test object. To this end, we provide a dedicated core team that familiarizes itself with the specific requirements and functions of your product and is available for the entire duration of the project.
In this way, we guarantee efficient project management and enable a seamless transfer of knowledge when individual team members change.
