Sample text

The breakdown of developers’ time on activities (Figure 2 and Figure 3) shows that developers spend only about 1/3 of their time on coding related activities while another 1/3 of the time they navigate the Internet and about 1/4 of the time they use communication tools. Additionally, only navigating through the file system or searching for a file takes about 4% of the time developers interact with their computer. Consequently, conclusions H3 and H4 are the following: H3. Developers spend about 1/3 of their time on coding related activities, 1/3 on browsing the Internet and 1/4 on communication.

It is worth noting that while agile practices, like Scrum and XP, often give the team as a whole a great deal of autonomy, it does not follow that the individual team members are given high levels of individual autonomy. Barker [7], for example, pointed out that self-managing groups may end up controlling group members more rigidly than they do under traditional management styles, while Markham and Markham [8] suggested that it may be difficult to incorporate both individual autonomy and group autonomy in the same work group.

1 shows the TDD conformance of the three groups as boxplots (grey) with the data points (black) as overlay. At first glance the TDD conformance in the expert group seems to be higher than in the two novice groups. 203. Consequently, we cannot reject the null-hypothesis that all groups are equal. 2 Time Next, we compared the time needed for implementation. It is defined as the time span from handing out the task description to the final acceptance test minus the time for the initial reading phase, breaks, and the acceptance tests.
