This topic defines some of the terms used in the textual descriptions generated
by Project Reporter.
This refers to the status of a project, task, or milestone, with reference to
project schedule. The possible values for a task or project are:
For a milestone, the possible values are:
the start date is after the current reporting date.
the start date is before the current reporting date, and the finish date is
after the current reporting date.
the finish date is before the current reporting date, and the task or project is
the (scheduled) finish date is before the current reporting date, but the task
or project is less than 100% complete.
Note: Project Reporter assumes that milestones
have zero duration and cost.
the milestone is 0% complete.
the milestone is 100% complete.
Earned value fields (BCWP, BCWS, ACWP, CV, SV, BAC, EAC, VAC, CPI, SPI, TCPI)
These fields are commonly used as metrics to evaluate the cost and schedule
performance of a task or project. They stand for the following terms:
CV, SV, CPI, SPI, VAC, EAC, and TCPI are defined as follows:
BCWP: Budgeted Cost of Work Performed
BCWS: Budgeted Cost of Work Scheduled
ACWP: Actual Cost of Work Performed (this is the same as Actual Cost).
CV: Earned value Cost Variance
SV: Earned value Schedule Variance
BAC: Budget At Completion (this is the same as Baseline Cost).
EAC: Estimate At Completion (this is the same as Cost, except in Microsoft
Project 2002 see below).
VAC: Variance At Completion
TCPI: To Complete Performance Index
Note: Project Reporter uses the first definition
of the CV field shown above (as do Microsoft Project 98 and Project 2000/2002),
and recalculates CV where necessary. Project Reporter also calculates the TCPI
field using the formula shown, in formats prior to Microsoft Project 2002 where
it is not defined directly. Task EAC is not recalculated for formats prior to
Microsoft Project 2002; in those formats it is taken to be the same as Cost.
CV = BCWP - ACWP (except in Microsoft Project 95, where the formula is ACWP -
SV = BCWP - BCWS
CPI = BCWP / ACWP
SPI = BCWP / BCWS
VAC = BAC - EAC
EAC = ACWP + (BAC - BCWP) / CPI (in Microsoft Project 2002, for tasks)
TCPI = (BAC - BCWP) / (BAC - ACWP)
Project Reporter also displays the following fields, where applicable:
CV% = CV / BCWP (Cost Variance Percentage)
SV% = SV / BCWS (Schedule Variance Percentage)
