started in the 1960s as a method for integrated project cost and schedule control
Earned Value Management
Objectives of EVM
For effective internal cost and schedule management control systems
For more reliable and timely data to determine product-oriented contract status
Five steps in EV analysis
Determine (work)
Determine (money)
Calculate
Analyze
Extrapolate
represents the baseline schedule and budget
budgeted amount of cost for work scheduled to be accomplished plus the amount or level of effort or apportioned effort scheduled to be accomplished in a given time period.
Budgeted cost for work scheduled (BCWS)
contractor’s earning for work performed, based on the contract price (earned value)
the budgeted amount of cost for completed work, plus budgeted for level of effort or apportioned effort activity completed within a given time period.
Budgeted cost for work performed (BCWP)
represents the actual costs spent so far
the amount reported as actually expended in completing the work accomplished within a given time period.
Actual cost for work performed (ACWP)
T or F: Minor variances are usually expected and tolerated
True
T or F: Major variances aren’t always investigated
False
T or F: For a negative variance (schedule or cost), it could be an indication of underperformance or unrealistic baseline
True
T or F: A large positive variance may not be a reason for celebration. It may indicate an error or an overestimation in the baseline budget and/or schedule.
True
T or F: Schedule performance and budget
performance are dependent of each other.
False
Earned value (BCWP) and actual cost (ACWP) may be plotted against the baseline (BCWS) as shown below. Both curves are usually extrapolated to forecast what
estimate at
completion (EAC) and the
date of completion.
Part of project control focused on quality feedback, progress of work, prognosis
Monitoring
Part of project control focused on revisions and adjustments
Updating
Parts of Project Control
- Budget control
- Schedule control
- Quality
- Safety control
Tasks in Monitoring Project
- Feedback from direct contact
- Feedback from photography
- Feedback from check-off list
- Feedback from Gantt charts
- Feedback from networks
Tasks in Updating Project
- Correction of the target plan to economically meet the project’s overall
objectives - Planning and scheduling the remaining work after some time interval has
elapsed.
Factors affecting updating phase
- Errors in activity durations and network logic
- Changes in project design or in project scope
- Procurement
- Impending strikes, jurisdictional disputes, and sudden changes in the availability of workers
- Accidents
a schedule that is prepared by the contractor, usually before the start of the project, and is used for performance comparison.
Baseline Schedule
reflects actual performance information—including time of occurrence and amount (or percentage) of work completed - on the schedule and indicates on the schedule any changes to future work.
Updated Schedule
date on which all progress on a project is reported. It is also called the as-of date, the cut-off date, and the status date.
Data Date
Type of information needed for updating schedules
- Past information
- Future information
Most common frequency of updating
Weekly and biweekly schedule updates
Methods in measuring work progress
- Involves mainly
calculating or estimating
the percent complete for
each activity. - May also include
estimating the percent
complete for the entire
project
