The Scrum Guide is the de facto standard for how to do Scrum for Scrum.inc.org.alliance. But at Net Objectives we believe you can and should go beyond it – pragmatism over dogmatism – work over framework.
There is, of course, a reason that the Scrum guide says “Scrum’s roles, events, artifacts, and rules are immutable.” And, if you are starting Scrum out on your own and you have control over your team that’s likely a good thing. But when Scrum doesn’t exactly fit, relaxing the rigor in the right way can make Scrum more effective.
But any change must be done with discipline and experience. In particular, you must be able to tell the difference between not doing a role, event, artifact or rule well, and it not being appropriate to do. When it is not proper for you (after all, no “one size fits all”) you can’t just drop that aspect of Scrum. You must understand the intent of what you’re dropping and manifest it another way.
This is where an experienced coach who knows Scrum, Kanban, Lean, XP or even other methods can be useful. If this makes sense to you, see the following links:
