This topic defines some of the terms used in the textual descriptions generated
by Project Reporter.
Completion status
This refers to the status of a project, task, or milestone, with reference to
the
current
project schedule. The possible values for a task or project are:
-
Unstarted:
the start date is after the current reporting date.
-
In progress:
the start date is before the current reporting date, and the finish date is
after the current reporting date.
-
Finished:
the finish date is before the current reporting date, and the task or project is
100% complete.
-
Late:
the (scheduled) finish date is before the current reporting date, but the task
or project is less than 100% complete.
For a milestone, the possible values are:
-
Incomplete:
the milestone is 0% complete.
-
Complete:
the milestone is 100% complete.
Note: Project Reporter assumes that milestones
have zero duration and cost.
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:
-
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
CV, SV, CPI, SPI, VAC, EAC, and TCPI are defined as follows:
-
CV = BCWP - ACWP (except in Microsoft Project 95, where the formula is ACWP -
BCWP)
-
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)
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.
Project Reporter also displays the following fields, where applicable:
-
CV% = CV / BCWP (Cost Variance Percentage)
-
SV% = SV / BCWS (Schedule Variance Percentage)
