Every job requires a measure of input to be delivered. And although performance is usually a measure of output, it is going to be unattainable without efficient input.

I will like to define Efficient Input as that minimum required input needed to deliver an excellent result. For instance, if your task is to deliver a painted wall, your efficient input will be the measure of time, skill and effort needed to give the best painted wall.

Dear friends, in all your daily task, keep this question in mind; what is the least input required of me to deliver an excellent result? And am I putting it in? In other words, is my input efficient?
Cheers.
