I honestly feel that's a very foolish way of working. What the hell has humanity come to?
Here is a symbolic example of how its so so wrong...
Say there is a report that describes what a great player Sachin Tendulkar is.
The executive summary: Sachin is a great player!
So what does the manager do?
He puts in Sachin in a Football field, "Go on sonny boy, I heard you are a great player. Go play!"
Sachin fumbles wondering "What the.....!"
Since he is caught in the situation, he tries getting on with the game.
In the end Sachin gets kicked out cause he couldn't kick.
OK you say. Good for him. Now he can get back to cricket. Right? Wrong!
Now his track record executive summary says,
"Pathetic player. So got kicked out"
So the no manager is interested in him in future, cos they will only look at this new high level summary.
They will show him the door, totally unaware of what they are missing out on and depriving sports world of.
Lets see another analogy.
A manager types person, who doesn't really understand art much might say
Mona Lisa executive summary : Its a portrait of a lady in gown with folded hands and a dumb look on her face.
The difference lies in the details stupid!
