> Think about small improvements that can move the team

Which team? My team of 5 people or the entire project of several hundred? Focusing on the small teams finds a lot of local maximums that are very bad for the entire project. Many of the small changes small teams want to make are not possible because they would impact some of those several hundred other developers. Often small pain for us is much better than the pain our change would force on those others.

By team I mean "the people you interact with [the most]". Those who impact your routine and are impacted by you most directly.

As I mentioned before, there is no one size fits all recipe. And there are no multiple recipes of different sizes.

There are infinite variables a group of people can express. There is no point in making recipes, agile is about ideals.
