For questions about engineering practices such as clean code, continuous delivery, continuous integration, etc.

Some methodologies prescribe specific engineering practices (for example, Extreme Programming prescribes Pair Programming, Continuous Integration, etc). This tag is not about their implementation (for those types of questions use Software Engineering Stack Exchange instead), but rather about the project management view of these practices (cost of their implementation, their benefits, their advantage and disadvantage, their affect to team productivity or whole project and others).
