I'm just curious as to if there have been changed in topicality recently, after I saw this question had been migrated from here to PM.SE:
Should a group of three students working on a big programming project have a leader?
There are a few ways to cut this. I organized them in order of my personal preference.
It's on-topic both here and at PM.SE. Migration {should | should not} (aside: my preference is should not have been migrated, especially since PM is not out of beta yet) have happened. It's a project management question, but software project management is inherently different than managing projects in other engineering disciplines or even cross-disciplinary projects. Since the main focus was software, it's on-topic here. However, since it has to do with subject matter in the Project Management Body of Knowledge (mainly Project Human Resources Management), it's also on-topic at PM.
It's on-topic here and should not have been migrated. One of the on-topic categories is "software engineering". My take on that is that the formal definition of what is included in software engineering should come from the SWEBOK. Software engineering management is a knowledge area in the SWEBOK, and therefore is on-topic here.
It's on topic here and should not have been migrated. The project, based on the question, is specifically and exclusively a software project. There was no mention of other engineering or business disciplines. The P.SE FAQ states that conceptual questions about software development are on-topic.
It's off-topic here because it's relevant to more than just software engineers. Although software projects are different than other projects, if and how to choose a leader remains the same. It's a cross-cutting PM concern of interest to all PMs, software or otherwise.
It's off-topic here because the question was worded to generally. Although it was a software project, no key concerns about developing software were identified. Unless there is some kind of demonstration of relevance to exclusively software, it should be moved.
I'm not sure who moved it, but these are what I see as the major possibilities for dealing with this question are. The only one I don't like is 5 - if that's the case, could the question have been edited to be made more specific?
I suppose this does prompt another question, though. How do we deal with a site like PM that's in such overlap with a huge chunk of relevant questions? It might be something to look at in the future.
