Worker Efficiency

[Peter]

Hi,
I have a situation where I can estimate the number of hours it will take for
one person to complete a task but I want to add more resources to the task to
complete it more quickly. The problem is, MS Project assumes that by that
putting two people on the task it will be completed in half the time. This
is not the case however due to inefficiencies involving worker interactions.
So in reality, if my task would take 100 hours for one person to complete it
may take 60 hours if I had two workers on the task (hence the task would now
require 120 hours of labour but it would be completed in 60 hours time).

What I am trying to do is juggle my project completion times by adding more
resources however as MS Project assumes that two people on a task is just as
efficient as one, there is no "cost" penalty for adding more resources to a
project - just an up side of earlier completion.

Does anybody know how to deal with this effect in MS Project?

Hi,

As well as adding the second resource you need to edit the hours of work
they will do to include the collaboration overhead. There is no way Project
can predict this for any two individuals working on a specific task so it's
up to you to edit the work involved.
