One tool to rule them all? Integration or survival of the fittest

As a software developer or engineer you usually try to find the perfect tool for the task. A tool which covers all the needs you have. Therefore, if addressed with several tasks to solve, you will turn to the most powerful tools for each task. At the German aerospace center (DLR), a large research facility in Germany, we needed to update our basic software engineering tools (software repository (SVN), issue tracker (Mantis), and continuous integration (None)) which were used by 2.000 to 3.000 people. Instead of turning to the most powerful tools on the market, we decided to take a step back and ask the scientists what is most important to them. In this talk we present our results, the decisions we took based on them, and how the new solution has been received by the scientists.
