Level of Effort (LOE)

Level of Effort (LOE) is a type of work in government contracting and project management that is measured by the passage of time and the resources applied rather than by specific, discrete deliverables, earned value for LOE work accrues simply because time passes and resources are consumed, not because a specific outcome is produced.

What is Level of Effort?

In the EVMS framework, work is classified as either Discrete (with specific, measurable deliverables), Apportioned (a percentage of another work package), or Level of Effort. LOE applies to activities that provide essential support and management functions but do not produce discrete outputs that can be objectively measured. Program management, general and administrative oversight, configuration management support, and ongoing technical coordination meetings are typical LOE work packages.

For LOE work packages in EVMS, earned value equals planned value for each time period, the earned value rate is set to match the budget spend rate. This means LOE work packages never show a schedule variance (SV = 0) because earned value is defined as equal to planned value. Cost variance can still occur if actual costs differ from budget.

The significance of LOE classification is important in proposal and reporting contexts. Excessive LOE in a program's WBS (e.g., more than 10-15% of total contract budget classified as LOE) is a DCMA and government concern because it masks schedule performance. Programs with high LOE content appear to perform on schedule even when discrete technical work is behind. Government program offices push contractors to minimize LOE classification and maximize discrete, measurable work packages.

Why LOE matters for government contractors

Contractors must carefully and defensibly classify work packages as LOE, discrete, or apportioned in their WBS dictionaries. Misclassifying inherently discrete work as LOE to avoid negative schedule variance reporting is a significant EVMS deficiency that DCMA will flag. Conversely, failing to classify legitimate support work as LOE forces artificial discrete measurement that does not reflect actual work character.

Example

A defense contractor's program management work package, covering the program manager, deputy PM, and program control staff, is classified as LOE at $150K per month. As long as these personnel are employed and working, earned value equals planned value each month, producing no schedule variance for this work package. The contractor's EVMS report shows the LOE portion separately, and the DCMA analyst notes that LOE constitutes 8% of the total program budget, within acceptable limits.

Frequently Asked Questions

What percentage of a program budget is typically LOE?

DCMA and government program offices generally expect LOE to constitute no more than 10-15% of a total program budget. Programs with higher LOE percentages receive scrutiny about whether discrete work is being inappropriately classified as LOE to avoid schedule variance reporting.

Can LOE work packages have cost variances?

Yes. While LOE work packages never have schedule variances (by definition, earned value equals planned value), they can have cost variances if actual costs (AC) differ from the earned value (EV = PV). A program management work package budgeted at $150K/month that actually costs $170K/month has a -$20K monthly cost variance, which accumulates into the cumulative CPI.

What types of work are typically classified as LOE?

LOE work typically includes program management, configuration management support, meeting facilitation and scheduling, contract data requirements list (CDRL) management, administrative and clerical support, ongoing test and evaluation monitoring, and similar support functions that are sustained throughout the contract period regardless of technical progress.

How is LOE different from a time-and-materials contract?

LOE is a work package classification within an EVMS framework that describes how earned value is measured. A time-and-materials (T&M) contract is a contract type where the government pays for labor at fixed rates plus actual material costs. Many LOE work packages are priced on a T&M or labor-hour basis, but LOE and T&M are concepts from different domains (EVMS vs. contract types) that frequently appear together.
