Adding a team to catch up
If a project that consists of 2 teams is behind, it makes sense that adding an additional team would help catch up, at least on the surface. The comments I am getting back are, that adding additional people to an already existing team could disrupt the team and actually cause them to be less productive. I get that. But wouldn't adding another team be a reasonable solution? I thought that one of the benefits of scrum was scalability.
Stories and work are relatively small portions of a larger piece of work. Doesn't that lend itself to introducing a new team and being more productive and useful than adding additional people would have been for a waterfall project?
If more people are available, it could give them more options when self-organizing into teams which are appropriate for the work.
What, though, would they be expected to "catch up" on? In what sense are they "behind"? What sort of commitment is implied here, and who made it and why?
