TABLE 10.2 Work Package Estimate: Example 1
Task description: During an environmental study, a power company counts salmon during a 40day salmon run.
Assumption: The federal agency overseeing the power company dictates the length of the study.
Duration: 40 days		Materials: None
Labor and Equipment Table
Type	Average Use	Total
Salmon Specialist	1 @ 10 hrs./day	400 hrs.
Field Technician	2 @ 10 hrs./day	800 hrs.
Truck	1 all day	40 days
Increasing the number of people on this task does not change the duration but it could increase the accuracy of the study.
TABLE 10.3 Work Package Estimates: Example 2
Task description: During a training project, software is upgraded on 20 workstations in a training room.
Assumption: The average time to install the software is 2 hours per workstation. Testing is 1 hour per workstation. Only one person can work on one workstation at a time.
First Estimate
Duration: 5 days	Materials: 20 copies of the new software
Labor and Equipment Table
Type	Average Use	Total
Computer technician	1 @ 8 hrs./day	40 hrs.
Tester (user or technician)	1 @ 4 hrs./day	20 hrs.
Software test kit	1 per tester	1 test kit
The training manager does not want the training room out of use for a whole week. In fact, he wants the upgrade done over a weekend so the training room doesn't lose any availability.
Revised Estimate
Duration: 2 days		Materials: 20 copies of the new software
Labor and Equipment Table
Type	Average Use	Total
Computer technician	2 @ 10 hrs./day	40 hrs.
Tester (user or technician)	1 @ 10 hrs./day	20 hrs.
Software test kit	1 per tester	1 test kit
By adding 1 computer technician and working longer days, the duration is cut from 5 days to 2.
TABLE 10.4 Work Package Estimates: Example 3
Task description: A government agency is mapping a forest. Aerial photography of the entire area is the first step in creating the maps.
Assumption: An aerial photography subcontractor rents airplanes (complete with pilots and photographers). The agency has one scientist ride with every airplane. The forest is broken into 60 squares. They can photograph one square per day. During the flight, a ground technician stays in radio contact with the scientist to answer mapping questions.
First Estimate
Duration: 60 days	Materials: None
Labor and Equipment Table
Type	Average Use	Total
Scientist (in plane)	1 @ 8 hrs./day	480 hrs.
Airplane	1 @ 8 hrs./day	480 hrs.
Ground technician	1 @ 8 hrs./day	480 hrs.
The forest area traditionally has so much cloudy weather that the agency estimates there will be only one clear day out of every three, but the photography needs to take place during the three months of summer when there is no snow.
Given this requirement, they decide to fly two airplanes every clear day. On days they can't fly there is no airplane cost and the scientist and ground technician can work on other things. A single ground technician can stay in contact with both airplanes.
Revised Estimate
Duration: 90 days		Materials: None
Labor and Equipment Table
Type	Average Use	Total
Scientist (in plane)	2 @ 2.7 hrs./day	480 hrs.
Airplane	2 @ 2.7 hrs./day	480 hrs.
Ground technician	1 @ 2.7 hrs./day	480 hrs.
Since one ground technician can talk to both airplanes, the total labor for that person is cut in half. The expected hours for the scientist and the airplanes stay the same.
The average use estimates are used during the resourceleveling step to indicate the average amount of time the scientists and ground technician will have available to work on other projects during this 90day period.
TABLE 10.5 Work Package Estimates: Example 4
Task description: A systems analyst is working on three projects at the same time. One of her project managers asks her to estimate the design of a subsystem.
Assumption: She will continue to work on all three projects simultaneously.
First Estimate
Duration: 40 days	Materials: None
Labor and Equipment Table
Type	Average Use	Total
Systems analyst	1 @ 2.5 hrs./day	100
Her project manager needs the design performed much faster and suggests he could get another analyst to work with her parttime.
Revised Estimate
Duration: 30 days		Materials: None
Labor and Equipment Table
Type	Average Use	Total
Systems analyst	2 @ 2.5 hrs./day	150
Adding people to a design task can speed up some of the work, but much of it will be done together so it results in an increase in the total labor cost. It is possible the resulting design will be better, but that is another assumption.
Then the project manager asks her what it would take to get it done the fastest. She responds, Talk to my other project managers and arrange to get me completely off those projects for a few weeks so I can concentrate 100 percent on yours.
Revised Estimate
Duration: 10 days		Materials: None
Labor and Equipment Table
Type	Average Use	Total
Systems analyst	1 @ 2.5 hrs./day	80
Not only is she able to spend more time per day on this task but she knows that if she is able to concentrate on it 100 percent she will be more productive.
