Much has been written about how complicated and difficult Earned Value Management (EVM) can be, and a term that has grown in popularity in response to this perception is “EVM Lite.” One of the problems with the term “EVM Lite” is that it suggests a version of EVM that is incomplete in some way.
In fact, proponents of EVM Lite sometimes suggest whittling down the 32 guidelines into just 10 core guidelines. But what many people don’t know is that the EIA-748 32 guidelines were always meant to be scaled for different project types. NDIA, which authors the EIA-748 guidelines, recently addressed this by producing the Earned Value Management System (EVMS) Scalability Guide, on which I was proud to be a contributing author.
A “scaled EVMS” makes it clear that there is a range of implementation options, from doing a simple CPI and SPI calculation in a schedule, to implementing a fully EIA-748 compliant EVMS on a government contract. Scalability suggests that a range of implementation options could apply to different types of projects. I highly recommend reading the NDIA EVMS Scalability Guide and using it to help tailor your own implementation. In the meantime, here are five ways to get started.
I recommend starting with a corporate policy that defines when and how EVM will be applied on various types of projects your organization may execute. Define the system in tiers, from the lowest (perhaps just a comparison of budget and actuals with no earned value at all) to a fully EIA-748 compliant system. Where a project fits in the tiers could be based on many factors, such as:
Project Owner: Is this an Internal Investment or Contract?
Contract Type: For contracts, is it a T&M, CP, or FFP? Is EVM a contractual requirement?
Project Type: Software Development, Construction, Engineering, Manufacturing, Operations & Maintenance, Research, etc.
Project Size: Consider both the total value and length of the project
Risk: Is this something that has been done before, or is it entirely new?
In my experience, 4 or 5 tiers is adequate. Each tier will have increasing reporting, process controls, compliance, and surveillance requirements.
One of the ways in which the EVM methodology is designed to be scalable is by using a product-oriented Work Breakdown Structure (WBS). Smaller projects simply don’t need to be broken down into a lot of detail. Sometimes a WBS that only consists of 2 or 3 levels is good enough to manage. Less WBS elements on a project means fewer control accounts and charge numbers, significantly reducing the administrative burden of managing the data.
EIA-748 guideline #2 requires that an Organizational Breakdown Structure (OBS) be created that depicts how the project will be managed, including major subcontractors. The intersection of the OBS and WBS defines control accounts.
While complex projects will have multiple levels of an OBS hierarchy, simpler projects, such as projects being performed by a single functional organization, may only have one level to an OBS. In these cases, the project manager would be the Control Account Manager (CAM) for all the work on the project.
Federal Acquisition Regulations (FAR) mandate Earned Value Management to be performed on development contracts that are more than $20M in value. These contracts tend to be cost plus, and thus EVM is often associated with requirements to report on direct and indirect costs. This necessitates the use of EVM software that can support complex rate escalations and burdens.
But these complexities are due to contract reporting requirements and government accounting regulations and have little to do with EVM. For T&M or Fixed Price contracts, and for internal investment projects, it is fine to plan and manage in whole dollars, and this can usually be done directly within the schedule without additional software.
Earned Value Management Systems are often associated with lots of administrative paperwork. But there is nothing in the EIA-748 guidelines, or in any other published EVM standard, that requires this. Two factors are generally responsible for the paperwork and approval processes commonly in place for an EVMS.
1. Compliance with federal contract regulationsOrganizations that have an EIA-748 validation requirement need to maintain detailed records to support audits by the Cognizant Federal Agency (CFA). This will include detailed budget logs, work authorization documents, baseline change requests, etc. All of this paperwork will have approvals associated with it, and must be validated and traceable across systems in order to meet compliance requirements. While there is certainly some value to the organization to have auditable systems in place, it may not all be necessary if compliance and external surveillance are not required.
2. Contractual reporting requirementsFor government contracts that require EVM reporting, the format is usually the Integrated Project Management Report (IPMR) or Integrated Program Management Data & Analysis Report (IPMDAR). Both reports require a bit of effort to produce, with the most intensive effort usually focused on the Variance Analysis Report (VAR) component (Format 5 for the IPMR, Narrative Summary for the IPMDAR).
