You use the word /define/ wrongly. Please see 
https://en.wikipedia.org/wiki/Definition . Florian gave you the exact 
definition.
You probably meant it is hard to /estimate/ the unknown parameters.

Furthermore, it is wrong that a user can judge better than a developer. 
The quality of a judgement doesn't depend on the role of the person.

No, you are wrong. The "resulting benefit" is not taken into 
consideration. You compare the times you need to get to the "resulting 
benefit" once without the work X (in my example "without documentation") 
and once with the work X (in my example "with documentation").
