I was the one who migrated it after a quick consultation with the other moderators. As an aside, you can click on the "programmers.stackexchange.com" link in the "Migrated from" banner on PM to get back to the original question here.

The reasons for the migration were a combination of #1, #4, and #5 on your list. The question (while mentioning a software team) did not focus on software development aspects of the project and the answers did not provide any information that was uniquely related to software development either.

It was a general question that could be summarized as "should we have a project manager/leader?". The type of project appeared to be irrelevant, and I think that made the question a better fit for PM than for us.

Far as editing the question to be more specific, I'm not sure how anyone except the OP could do it. We could've asked the OP to edit it, I suppose, but I'm not sure what that'd gain us when the question as it stands is pretty good as is, but simply better for another site.
