Notes

We developed Scrum in the early 1990s. We wrote the first version of the Scrum Guide in 2010 to help
people worldwide understand Scrum. We have evolved the Guide since then through small, functional
updates. Together, we stand behind it.
The Scrum Guide contains the definition of Scrum. Each element of the framework serves a specific
purpose that is essential to the overall value and results realized with Scrum. Changing the core design
or ideas of Scrum, leaving out elements, or not following the rules of Scrum, covers up problems and
limits the benefits of Scrum, potentially even rendering it useless.
We follow the growing use of Scrum within an ever-growing complex world. We are humbled to see
Scrum being adopted in many domains holding essentially complex work, beyond software product
development where Scrum has its roots. As Scrum’s use spreads, developers, researchers, analysts,
scientists, and other specialists do the work. We use the word “developers” in Scrum not to exclude,
but to simplify. If you get value from Scrum, consider yourself included.
As Scrum is being used, patterns, processes, and insights that fit the Scrum framework as described in
this document, may be found, applied and devised. Their description is beyond the purpose of the
Scrum Guide because they are context sensitive and differ widely between Scrum uses. Such tactics for
using within the Scrum framework vary widely and are described elsewhere
