The document discusses how to calculate the elapsed time to complete a task based on a resource's proficiency code (RPC) and availability code (RAC). It provides an example where a 6 hour task would take 18 hours to complete given an RPC of 0.8 and RAC of 0.5, plus a 20% contingency.

1. Elapsed Time
HOW LONG IS IT REALLY GOING TO TAKE

2. Resource Proficency Code
 RPC Indicates how proficient a resource will be at
executing a given task.
 0 ------------------ 1
 Lowest ----------- highest
 Assume RPC = 0.8
 So, Elapsed Time for a 6 hour Task= 6/RPC
 = 6/0.8 = 7.5 hours

3. Rescource Availability Code
 RAC specifies the availability of the resource to work
on the task.
 0 ------------------ 1
 Lowest ----------- highest
 Assume RAC = 0.5
 So, Elapsed Time for the 6 hour Task= 6/RPC/RAC
 = (6/0.8)/o.5 = 15 hours

4. Add Contingency
 Add 20% contingency to allow for any unforeseen
events/emergencies
 Assume contingency = 20%
 So, Elapsed Time for the 6 hour Task= 6/RPC/RAC
+ contingency
 =( (6/0.8)/o.5 ) + (15%)= 18 hours
