Please try all of Scrum.
Scrum is a bare framework. It is very simple. Scrum is not trying to be a full methodology.
Lots of people are doing Scrum-Butt. “We do Scrum, but…”
Then they say…
…we don’t have a product owner.
…we change the length of the sprint often
…we don’t have a ScrumMaster
…we don’t do a _daily_ scrum
I strongly urge you to try all of Scrum. No Scrum-Butt. Because I think more success will result for you, for your team, and for your customers.
If, because of impediments, you are doing Scrum-Butt now, this is understandable. Let me just ask two things. Try to fix the impediments, one at a time. And tell yourselves and tell others….”well, we are trying to do all of the bare framework of Scrum, but so far we are doing Scrum-Butt…”
I think these simple ideas will help you and others.
