ems:scenario
The
ems:Scenario resource that defines the assumptions for this estimate.
ems:predicts
This property gives a prediction for this estimate. An estimate may have zero or more predictions. The object of this property is an inline
ems:MeasureDistribution resource.
A prediction is any condition or constraint that may be measured for the project, e.g. schedule, staffing, scope. Predictions often involve imprecisely known quantities such as effort or quality. The uncertainty in predictions is expressed by giving a probability distribution for the predicted quantities.
ems:assumesTable
Like ems:predicts, except that the object of this property is an inline
ems:FactDistributionTable resource.
ems:assumesWbs
Like ems:predicts, except that the object of this property is an inline
ems:WorkBreakdownStructure resource.
