Agile software development and management related to Scrum model is gaining popularity. It may differ significantly
from classical development schemes widely discussed in the literature. An interesting issue is to evaluate project
progress and the effectiveness of task handling in Scrum based development. This process can be supported with an
advanced study of repositories provided by issue tracking and project management software. This is neglected in
publications on Scrum methodology. In the paper we present some original analysis schemes which have been verified
using repository data from a commercial project involving developers from multiple sites. In the presented approach we
exploit our experience with other development techniques targeted at big and complex open source or commercial
projects. It has been adapted to the specificity of Scrum model and relevant software repositories.
