I am wondering why the following question has been downvoted
Clearly, code reviews and team dynamics are not pure software engineering. But we often have accepted questions on Scrum/Agile/TDD/DDD etc
I would like to suggest that we specifically allow questions on "Working practices/project management in software development teams" under the "software development methods and practices" heading.
The linked wikipedia article is flagged for attention, very fuzzy and unclear in my view.
My feeling is that these day to day practices and procedures form a large part of what software engineering is in practice and we could call out specific examples of what "methods and practices" means.
