```Activity 4.2
1. How is total work calculated?
Task Duration (in hours) * Number of resources assigned to task.
2. What is the general formula used to calculate work for a task?
Work=Duration*Units
3. What is the value of work calculated for a task that does not yet have a resource
assignment?
When no resources are assigned, the work value is calculated at 0 hours. This results in the
formula always having an end result of 0.
4. How is the duration of a task scheduled when two resources are assigned and they are given
different work values?
When two resources are given to a single task and it will take longer than the working time
of 8 hours, one person or resource will be dedicated at 100% for 8 hours, while the second
resource will need to put in a certain % in order to complete the nominated hours it would
take to finish that particular task.
5. With effort driven scheduling, what is held constant and what is decreased in the W=D*U
formula when an additional resource is added?
Work/Effort driven scheduling deems work/effort to be constant and duration to decrease.
6. With fixed duration scheduling, what is held constant and what is increased in the W=D*U
formula when an additional resource is added?
The opposite to effort driven scheduling, in this case duration remains constant and
work/effort decreases/varies for each resource.
7. What is the default task type?
The default task type in Project 2010 is ‘Fixed units’.
