Fragments of focus
There are two types of time that you need to recognise.
There is fragmented time.
And there is focused time.
Project managers have fragmented time.
Their world revolves around meetings and dealing with small blocks of time; fifteen minute meeting here, five minute conversation there, and so on.
Software developers, engineers, artists all require focused time.
For them to be productive their schedule requires that they have large blocks of time to set aside to make the things they make.
Team leads often need to straddle those two worlds and it is never an easy job for them.
