Rashmi varma wrote:Yes , in my opinion scrum does not really suit a maintenance project and I have given detailed explanation for it as well.
Rashmi varma wrote:Why I believe it doesn't work is because in a maintenance cum development project you cannot keep control over expedite tasks , critical tickets from customers , Spikes and issues coming at us from other teams and not to forget sick leaves. These are variables , not measurable and therefore it is very difficult to include these variables to achieve a definite number of stories. WHAT IS your view about this ? Does the book discuss this aspect of scrum and agile?
Rashmi varma wrote:Another thing which puzzles me the most is the story sizing based on T-shirt sizes. Now they are relative but in maintenance teams many of the issues are one of a kind for eg. a DIFFERENT DB error every time , so we cannot really relate to a base case until we have investigated it and found out the real problem (which usually takes more time). And once we know the real problem , almost every solution is XS/S . In any refinement meeting even if we feel a story is bigger than S and we cannot divide it further , we are too afraid to use M because well with T shirt size , the size of the story point increases exponentially (or in a fibonacci series ). HOW do you think we can handle the sizing in a project where we have several "kinds" of stories without any base case to compare with? IS it really suitable for us? DO you think kanban(scrumban) is more suitable for these kinds of projects?

Be creative. Understand the principles and values of Scrum and follow those over the letter of the law. I'd say my team does 90% of Scrum. But Scrum is a means to and end and we are achieving that. (Well not an end. Continuous Improvement)
In Chapter 2, Uncle Bob wrote:I expect estimates, and I expect them to be honest. The most honest estimate is “I don’t know.” However, that estimate is not complete. You may not know everything, but there are some things you do know. So I expect you to provide estimates based on what you do and don’t know.
