The Impact of Number of Sites in a Follow the Sun Setting on the Actual and Perceived Working Speed and Accuracy: A Controlled Experiment

Follow the sun (FTS) software development seems promising in theory, however well founded knowledge on its successes is rare. One of the questions unanswered is: what is the impact of increasing the number of sites in a FTS cycle on working speed and accuracy? In this paper a controlled experiment is presented in which the impact of the number of sites in a daily cycle in terms of overall working speed, individual working speed and working accuracy is measured. Furthermore, the participants perception of working speed and their perception of working accuracy is investigated. The results indicate a clear discrepancy between actual and perceived performance, when increasing the number of sites.
