One of the "unsaid" parts of taking over a program:

What "Traditions" does the program have that the community will be upset if they are not continued?

For example - some schools do a "dance show" after UIL. Some schools always play a certain song at the start of the fourth quarter. Some schools have a different take on a band banquet. Some schools have an "adopt-a-freshman" program. Some have a particular cadence or three that are part of the everyday rotation.

Figure out what SHOULD NOT be changed - and remember that some traditions exist because a director did it for two years, and now "we have to" even though it may not be a real thing.
