Gather Requirements the Agile Way

In the post Self-organize using Scrum we saw that Scrum supposes that the Product Owner can fill the Product Backlog with stories, ordered by the desired sequence of implementation. Furthermore Scrum supposes that the team estimates these stories and comes up with a Definition of Done that will ensure a common understanding of the desired quality constraints. It doesn’t say where the information comes from that is needed to do these things. Speaking with Jeff Sutherland (one of the founders of Scrum) – “this stuff magically appears”. In this section we will look at the way Agile requirements practices can help in this regard.

The New New Scrum Rules of Play

(Deze blogpost is ook beschikbaar in het Nederlands)
Ten years after the creation of the Agile Manifesto and the publication of the first book on Scrum, sixteen years after the first presentation of Scrum at OOPSLA'95 and Twenty Five years after the publication of a scientific article that inspiered the name Scrum, the new Scrum Guide 2011 by Ken Schwaber and Jeff Sutherland is out. It has some great new insights to offer. In this post we will take a brief look at the history of Scrum, see what this new Scrum Guide has to offer and visualize the New New Scrum Rules of Play. This can be of interest to people with some knowledge of Scrum but can hold insights for experienced Scrum practitioners as well.
