Analyzing tool usage to understand to what extent experts change their activities when mentoring

There is a notable difference in the way the tools are used between the experts working together and the experts mentoring the new developers that have just joined the team, and over time the difference between pairs of experts and mixed pairs working together becomes almost unnoticeable.

Predicting Development Effort from User Stories

In this paper, we propose a method for predicting development effort based on user stories. Such approach is well suited for Agile software projects where requirements are developed along with the project and only sketched in a rough manner. We apply the proposed method to two industrial Agile software projects of very different size and structure. We show that such effort estimation works reasonably well if user stories are written in a structured way.

Failure Prediction using the Cox Proportional Hazard Model

Log messages are proposed to be used to predict failures running devices that read log files of running application and warns about the likely failure of the system; the prediction is based on the Cox Proportional Hazards (PH) model that has been applied successfully in various fields of research.
