You are, of course, right... I've fixed the text accordingly. Thanks.

Hi Tom,
Actually,you have mistaken the words said by Cohen. If it takes a month for a programmer to complete a software task then it is called one man-month. Your question is same as ''If it takes 10 minutes for a man to walk to some place, then what is the time taken by 10 men to walk the same distance?''. Obviously, it is 10 minutes only, not 1hr40mins. It's just a general sense.

Right, it is 10 minutes but 100 man-minutes.

You need to understand 10 people each walked 10 minutes, and when counted as a sequential set of processes, it is 100 minutes walked.

Imagine it as a baton race, 10 runners running 10 minutes each. Each runner ran 10 minutes, but the entire race lasted 100 minutes.

Imagine it as a baton race, organised by a game of Chinese Whispers. It will take at least 200 man-minutes, and which way were we running again?

This not the reality because 10 mens can have a very nice talk, and it can take 1hr40mins or more.
So the problematic is on link beetween people. So the subject is humain, and very actual.
