What are
estimating factors?
Productivity and utilization are the two factors we are
concerned with when doing estimating for projects. Both of these factors are
applicable to cost as well as schedule estimates. Productivity is a measure of
how much faster or slower a particular resource is from the normal resource. A person who is very good or very experienced at
what they do will probably take less time and make fewer mistakes than a new
person with little experience. Productivity factors allow us to adjust the cost
or the duration of the task depending on the particular individual used.
Utilization is another adjustment factor to the cost estimate.
Utilization is based on the idea that even though we pay someone for a full
eight-hour day, the person seldom, if ever, actually works the full eight hours.
Utilization is a way of adjusting the cost of a task to allow for the time that
the person is being paid but not actually doing things that are productive.
