Continuous integration (CI) ensures that code from different individuals integrates properly. CI compiles the entire codebase, deploys and tests it with each change. CI alerts developers of any problems as errors can be fixed more easily if caught earlier in the process. This paper compares the effectiveness of different types of mechanisms for notifying developers to a successful or unsuccessful build. Two different quantitative and qualitative user studies were performed testing the effectiveness of three types of notification devices one virtual e-mail based mechanism, one using ambient lava lamps, and one robotic device. The results show that most developers preferred an easily visible but unobtrusive ambient device combined with an e-mail describing the problem in more detail.EngComputer Scienceunknown2008-888-0110.11575/PRISM/30576
