If you remove a rule in scrum, do you stop calling it scrum?
So my question is around the context, there are 9 rules is scrum. If for say, we decided to remove the daily stand-up. Do you stop calling it scrum if it now has only 8 rules?
The Scrum Guide says:
“Scrum’s roles, events, artifacts, and rules are immutable and although implementing only parts of Scrum is possible, the result is not Scrum.”
I believe Scrum.org recognise such situation as "ScrumBut".
ScrumButs are reasons why teams can’t take full advantage of Scrum to solve their problems and realize the full benefits of product development using Scrum. Every Scrum role, rule, and timebox is designed to provide the desired benefits and address predictable recurring problems. ScrumButs mean that Scrum has exposed a dysfunction that is contributing to the problem, but is too hard to fix. A ScrumBut retains the problem while modifying Scrum to make it invisible so that the dysfunction is no longer a thorn in the side of the team.
If you call something Scrum, but you aren't following "the rules", then transparency is reduced.
If there is a decision not to Scrum properly, and that ultimately doesn't work, it is helpful if everyone at least understand that the failed experiment was not Scrum.
