As such, its uses include providing: a description of the application details for the program personnel who use the EVMS; supplemental training documentation for people new to the system; and an overview description for customers.
Earned Value System Description
Variance where ACWP is subtracted from BCWP
Cost Variance (CV)
ACWP
Actual Cost of Work Performed
Index where BCWP is divided by BCWS
SPI
This Christmas song contains the lyrics ‘He’s making a list, he’s checking it twice’
Santa Claus is Coming to Town
This earned value technique calculates the percent complete of a work package based on the actual costs using the formula (Actual Cost/EAC) X BAC. This technique is utilized for engineering material (high volume/low value).
Earned as Spent
CPI is considered (blank) if it is greater than 1.0

Heather Robertson's favorite schedule metric, therefore it is all of our favorite schedule metric.

Status of a WP that has actuals incurred or contains BCWS in the prior or current period
Open WP
Earned Value Technique where BCWS will always equal BCWP

This may be implemented when the budget and/or schedule for performing the remaining work is decidedly insufficient and no longer represents a realistic plan for managing the program. Prior to implementation, written approval must be received from the Contracting Officer.
Formal Reprogramming
This index is used to determine how efficient you need to be to meet your target BAC, LRE, or EAC
To Complete Performance Index (TCPI)
SRA
Schedule Risk Assessment
Measures the number of tasks completed as a ratio to those tasks that should have completed to date according to the original (baseline) plan. It reveals the “execution pace” for a program and provides an early warning of increased risk to on-time completion.
Baseline Execution Index (BEI)

This period is defined to be the current accounting month where no budget or schedule changes are allowed for work already in progress or for work scheduled to start unless the changes are customer directed, are adjustments, for rate changes, economic price adjustments, the correction of errors, or as described in Section 6.3.2 Internal Planning and Figure 14: Replan Implementation Matrix.
Frozen Period
The contract price is equivalent to profit/fees plus...
Total Allocated Budget (TAB)
LRE
Latest Revised Estimate
Measures how realistic the program completion date is, based on the remaining duration of the critical path and the amount of total float available. One of DCMA’s 14-Point Assessment Metrics and identifies programs that are having difficulty executing their critical path. The target is 1.0 or greater. A lower value indicates an increased risk of being late at program completion.
