I'm going to begin a universitarian project with my fellows: it is required that we use one of the Agile Methods together with Bitbucket. We'd like to begin with Scrum: I've red its documentation and it seems very powerful.
My doubt is about the sprint in Scrum and the branch in Bitbucket; can we say that sprint and branch are almost the same things?
If so, we will open our very first branch in Bitbucket and this will be our first sprint. Is this the correct interpretation of this method or it would be more appropriate (by "appropriate" I mean "following best practice") for every member of our group to open its own branch?
a Sprint has nothing to do with a Branch. A Branch is copy of your source code to be able to isolate changes from the main repository. A Sprint is a timeboxed event with the goal to create a potentially releasable increment of your product.
