What is your policy?
Get it first and there after only think about the infrastructure requirements.
Set up the infrastructure first and then only get it.
In the morning
Mr X: Sir, we need a copy of one of these three documents:- certificate 1, certificate 2, certificate 3
Mr Y: Okay come by evening. I will arrange it.
In the noon
Mr X: Sir, I just came to show you a sample of certificate 2. Hope you will do the needful
Mr Y: Okay.
In the evening
Mr Y: I have taken the copy of certificate 1. Hope this will suffice
Mr X: Oops, no Sir. I want the certificate 2 itself, that’s what I have shown you in the noon.
Mr X: What….???
Do you find something amiss in this communication? In fact both X and Y failed to communicate properly.
Mr X could have told that he wants a copy of certificate 2 only and explicitly mention on the non-necessity of the other two items.
Similarly Mr Y could have asked while he was back with a sample of a particular certificate alone. He could have checked it then and there itself and ensured the actual requirements.
