Abstract:

Scrum has become the most used agile methodology, mostly for standard information systems development projects. In general, agile meth-odologies are considered as an alternative to standard rigorous methodolo-gies, which are still recommended for complex system development. We have adopted scrum during implementation of complex system integration project of the Identity and Access management for Telefonica O2 Czech Republic. Lessons learned from this case study are the main purpose of this article.
