An interesting observation as I work with several teams to migrate a very waterfall process to Scrum: it is ridiculously easy to let the tools and the ceremonies become pro forma exercises rather than thoughtful representations of the spirit of what we’re doing.
I think that the biggest value I add as a coach has been to remind entire teams—regularly—to focus on the spirit of the manifesto rather than following the “rules” for using the tools or ceremonies. The tools do not define our process, the tools are there to facilitate our process. Something to remember.
