A team has a lot of difficulty in performing system integration testing. What is the best way to address this?

Performing integration tests more frequently is beneficial because it allows the team to identify and address issues early in the development process. When integration tests are conducted regularly, it enables continuous verification that different components of the system work together effectively. This frequent assessment helps catch integration problems before they grow into larger, more complex issues, thereby reducing the overall cost and effort needed to resolve them later.

By increasing the frequency of integration testing, the team can better manage the complexity associated with integrating various components, as well as foster collaboration and communication around integration challenges. This approach also aligns well with Agile and Lean principles, where early and continuous delivery of valuable software is emphasized, facilitating faster feedback loops and allowing the team to adjust their work based on real-time insights.

In contrast, adding team members to testing may not address the root cause of the difficulties faced during integration. It may lead to a temporary increase in testing capacity but does not necessarily improve the testing process or reduce complexity. Performing testing only once at the end could lead to substantial issues remaining unidentified until late in the project lifecycle, resulting in potentially costly and time-consuming fixes. Lastly, finding a way to do less integration testing may overlook vital aspects of project quality and could lead to more significant problems with the final product,
