Many Pmos have a tool that they like to use for all kinds of jobs. It’s called Microsoft Excel.

When I was young, I always thought that the hammer was the right tool for any job, but my dad taught me that there’s a "right tool" for each job... and it's seldom a hammer.

You’ve no idea how much damage I did to his vintage motorcycles with that hammer. 

And the PMO's fondness for Excel does a lot of damage. Spreadsheets waste resources, end careers and even kill whole companies.
