PGB theory vs. PBG practice

Here's another PBG struggle my Teaching Pastor recently shared with our Board:

"In theory, the senior pastor is judged by adherence to policy limitations and outcomes, but in practice, most of his time is spent doing things which have no direct relation to them. For example, depending on the week, sermon preparation and planning can take from a third to a half of his time. People expect quality work at the high impact times of the week, namely weekend worship. There are myriad 'interruptions', even if one tries to manage time in a tactful manner."

I know I've struggled with this--a lot! Is your Board aware of this challenge? What are doing to address it?
