Any service managers or ex service mangers?

Sounds like you're not actually after "proficiency" as stated in the OP, but rather "productivity".

Not the same thing, may or may not be tied together.

The pitfalls, were pointed out, though.

I'll never forget the guy I worked with that got two bonuses in a row for "most work orders", pic in the news letter and everything.

Except his work was CRAP.

I personally had to go "fix" several of his "fixes".

This was building maintenance, though.

He did crap like- put the faucet knob on upside down and then tighten it so tight that it wouldn't move.
Really? How about- you try to turn it on before you leave.

Finally enough other guys bitched so much that they simply ended the program.
