Open Agile 2012 Timisoara, Romania Speech by Thomas Moedl, DialogData Agile practices and business analysis are often perceived to be at odds with each other. This talk aims to clarify why this discord need not exist and proposes that business analysts and agile champions work toward deriving benefit from using both, and exploit synergies that have the potential to dramatically improve the software engineering process. Particularly in large projects, where software systems are produced incrementally by several teams, one can observe risks regarding the quality of the results and the successful adaption of Scrum in equal measure. Evolutionary business analysis with user stories can provide a decisive contribution here, by adequately supporting agile project management in initializing the Scrum product backlogs and by generating the backlog entries.
