Evidence-Based Timelines for Project Retrospectives

Evidence-Based Timelines for project Retrospectives (EBTR) is a method that supports group reflection of the entire project life cycle. It can be used to assess and improve on, for example, the impact of requirements engineering on development projects.

The EBTR method was designed in close collaboration with one case company (papers 1) and evaluated for this first case company (paper 2). It has also been applied to another case by researchers from Fraunhofer Institute, Germany (case 2). Through comparison between the EBTR applications for case 1 and case 2 a set of variation points have been identified (paper 3) with which it is possible to configure the method to suit both broad and specific assessment goals, as well as, allow for other variations depending on the requirements of the specific case.
