Insights into Current Industry EVMS Issues

Quick Summary

  • The August 2026 NDIA IPMD forum emphasized using Earned Value Management Systems (EVMS) as an early-warning system that helps management identify risks, make timely decisions, and protect project outcomes.
  • Forum discussions included integrating subcontractor schedules into the Integrated Master Schedule (IMS), improving Schedule Risk Assessments (SRAs), maintaining credible Estimates at Completion (EACs) and forecast completion dates, and proactively managing Level of Effort (LOE).
  • The NDIA IPMD Clearinghouse Committee provides a forum for industry and government EVMS practitioners to discuss challenges and develop mutually acceptable solutions. H&A actively participates in these forums and provides related guidance through our blogs and articles.

H&A earned value consultants routinely attend and present at the NDIA Integrated Program Management Division (IPMD) forums that are held twice a year as well as serve on the IPMD Board of Directors. The IPMD forum presentations, discussions between industry and government customer representatives, and Clearinghouse Committee topics provide an opportunity to discuss current challenges and options for resolving them. If you are not familiar with the IPMD Clearinghouse Committee, a time slot on the agenda is reserved for this committee’s working session. Industry Earned Value Management System (EVMS) practitioners raise and discuss issues along with the government EVMS counterparts to develop mutually acceptable resolutions and/or recommendations. Issues raised during the Clearinghouse Committee sessions have often been the basis for launching many other IPMD committees such as the Planning and Scheduling Committee and Prime/Sub Committee.

In addition to EVMS related challenges that surface on recent H&A engagements, the H&A blogs and articles are often written to address common issues or general themes from these IPMD forums. The August 2026 forum was no different. What follows is a short list of discussion and presentation topics from the August 2026 forum with links to H&A blogs or articles that address these current issues and presentations.

  • The value of an EVMS. This was a general theme from three presenters that aligns with recent H&A EVMS Education Center articles including one titled “Ten Project Failure Risks: Using an EVMS to Improve Project Outcomes.” The purpose and value of an EVMS is often lost when the focus is on producing contractual reports or managing to a set of compliance metrics instead of using the data as an early alert system for emerging risks and issues. An EVMS provides management a disciplined way to understand the current status of a project and where it may be headed. Management must provide the response to the EVMS alert signals, make decisions, and take action while there is still time to protect project outcomes.
  • Approach for integrating subcontractor schedule data into a prime’s Integrated Master Schedule (IMS). There are often differing opinions from the contractor’s or the government customer’s point of view about how the IMS should be structured to include this data. The main goal is to determine a logical approach that does not overcomplicate the structure and content of the IMS that makes it difficult to maintain or compromises the overall purpose of an IMS. The H&A blog “Integrating Subcontractor Data into an Integrated Master Schedule” discusses this common challenge and risks when scheduling requirements are not clearly defined. It also discusses three approaches for incorporating subcontractor schedule data with pros and cons for each approach.
  • Schedule Risk Assessments (SRAs). The continuing discussions on SRAs often center around the quality of the SRA data and that it is being treated like a check the box exercise. The solution isn’t to require contractors to perform monthly SRAs. That fails to address the root cause: meaningless duration estimates. In some instances global factors are applied to existing duration estimates as a short-cut. Producing a useful SRA starts with a high-quality IMS along with a disciplined risk management process and focused analysis of selected tasks that have a high probability of impacting a major event or project completion date. The H&A blog “Maximizing the Value of Schedule Risk Assessments (SRAs)” provides suggestions on how to implement a straight-forward process that helps to produce a more realistic IMS.
  • Estimates at Completion (EACs). This is another continuing discussion between industry and their government customers about practices that help to ensure a contractor’s forecast completion date (FCD) and EAC are realistic. The H&A blog “Maintaining a Credible Estimate at Completion (EAC)” emphasizes the importance of realistic EACs and why it matters to all stakeholders. The blog discusses practices that can help to ensure EACs are actively maintained along with suggestions for practical process improvements including leveraging evolving tools and analytics.
  • Proactive management of Level of Effort (LOE). The LOE topic often comes up in the Clearinghouse working sessions. When the percentage of LOE work packages and their total budget value for a given project is low, some consider LOE to be a non-factor in the overall picture of project performance. However, that is not always the case. Selecting the LOE earned value method must be a conscious decision (not a planning short-cut) and actively managed to ensure the timing and duration as well as any relationship to discrete work packages remain valid. The H&A blog “Level of Effort (LOE) Best Practice Tips” discusses common LOE issues and provides suggestions on how to ensure LOE is properly planned and managed.

Revitalizing Earned Value Management Systems (EVMS)

Quick Summary

  • Regulatory changes and updated standards are creating an opportunity to revitalize EVM Systems. The FAR overhaul, revised agency thresholds, and the EIA-748-E streamlined requirements while reinforcing the continued need for an effective EVMS.
  • Organizations have an opportunity to refocus on value-driven EVM practices. Rather than treating EVMS as a check-the-box requirement, this is an opportunity to renovate bloated processes and remove non-value-added activities to establish a flexible “living” system that supports proactive project management and credible forecasting.
  • BI and AI tools can transform EVM data into a real-time decision-making advantage. When supported by reliable, integrated data, these tools can rapidly organize information, improve visibility, identify risks early, and help project teams respond faster to changing priorities as well as technical, schedule, and cost challenges.

With the recent changes in the government regulatory requirements, the publication of the EIA-748-E Standard for EVMS, and evolving Business Intelligence (BI) and AI tools, the components for revitalizing Earned Value Management Systems (EVMS) are falling into place. This is an opportunity to refocus on the original purpose of an EVMS and effective use of real-time EVM data to quickly address problems before they become critical.

As highlighted in a previous blog, “Earned Value Management (EVM): How Much is Enough?”, being merely “compliant” with the EIA-748 Guidelines should not be the goal. That strategy fails to take advantage of the benefits of an EVMS; it is also short-sighted. Too often an EVMS is perceived as a contractual check-the-box exercise or focused on detailed score keeping.

The goal should be about being efficiently expert at EVM; a commitment to become “best-in-class” as expert practitioners of EVM. Following this strategy, an organization’s EVMS is actively maintained and used to ensure it provides relevant, useful information needed to manage projects for success. EVM is a powerful project management methodology that integrates scope, schedule, and cost management to provide a clear picture of project performance, the forecast completion date, and estimate at completion. BI and AI tools are enhancing the ability to rapidly organize and analyze real-time EVM data for proactive management and clear transparent communication with the customer. This also aligns with the need for speed in delivering capabilities to the customer when trade offs between requirements, schedule, and cost must be made.

Trimming Contractual and Guideline Requirements

The regulatory environment has been evolving; government entities are either simplifying or changing the requirements for an EVMS. As a reminder, the Capital Programming Guide Supplement to the Office of Management and Budget (OMB) Circular A-11 Planning, Budgeting, and Acquisition of Capital Assets establishes the government major acquisition requirements for an EVMS. This Guide states contractors must use an EVMS that meets the EIA-748 guideline requirements to monitor contract performance. All agency EVMS regulations point to the A-11.

A summary of recent changes follows.

Revolutionary Federal Acquisition Regulation (FAR) Overhaul that began in May 2025 focused on removing most non-statutory rules and rewriting requirements in plain language. Subpart 34.2 – Earned Value Management System was trimmed to the basic EVMS and Integrated Baseline Review (IBR) requirements. The Pre-Award IBR and Notice of EVMS Post-Award IBR clauses were removed; it now just states an IBR is required. Subpart 52.234-4 – Contract Clause for EVMS text was streamlined. Key takeaways: Reaffirmed the value of an EVMS and IBRs. What is unchanged: An EVMS is required for major acquisitions for development contracts, requirements flow down to subcontractors, and IBRs are required.

Defense Federal Acquisition Regulation Supplement (DFARS) Class Deviations (2026-O0011 February 2026), in response to the FAR Overhaul. Subpart 234.2 Earned Value Management System, 234.201 Policy raised the contract value threshold from ≥ $20M to ≥ $50M for EVMS reporting and incorporated the 2015 Class Deviation Memo increasing the contract value threshold for compliance reviews to ≥ $100M. There are also new related Class Deviation Clauses: 252.234-7001 is now 252.234-7998 Notice of EVMS; 252.234-7002 is now 252.234-7999 EVMS.

NASA FAR Supplement 1834.201 Policy Class Deviation (June 2025) as well as their solicitation clause (1852.234-1) and contract clause (1852.234-2) align with the DoD contract value threshold changes and revised clauses.

National Nuclear Security Administration (NNSA). Although NNSA is part of the DOE, as of September 2025 they are the Cognizant Federal Agency (CFA) for NNSA projects. They purposely simplified their compliance and surveillance process to be able to rapidly respond to threats. Contractors self-assess their EVMS. NNSA uses an EIA-748 Guideline checklist, reviews data artifacts, and conducts interviews for evidence of compliance. Certification reviews are required when the Total Project Cost is > $300M and are subject to surveillance reviews.

EIA-748-E Standard for EVMS approved and published in February 2026. This long overdue update reduced the number of guidelines to 27 and reflects current business system capabilities. The previous set of 32 guidelines were revised or merged, two were added, and four were deleted to improve clarity.

With the publication of the EIA-748-E, industry guides as well as government agency compliance and surveillance review materials have been or are in the process of being updated. The NDIA IPMD Intent Guide for EIA-748-E will be available on the NDIA IPMD web site once it completes the membership review and approval process. The DoD Earned Value Management System Interpretation Guide (EVMSIG) is also being updated to reflect the EIA-748-E. Once the EVMSIG is published the DCMA EVMS Group will be updating their Business Practices, appendices, and EVMS Compliance Metrics (DECM). DCMA has already trimmed their DECMs to a set of 60 standard, 10 conditional, and 72 low priority tests.

Impact of BI and AI Enabled Tools and Apps

BI and AI tools speed up the process to pull data from different sources for defined use cases and to organize it for analysis. The time lag to view current data can be eliminated with the right business system interfaces and tools. These tools can quickly produce a variety of dashboards or data views with the ability to drill down into the data as well as to sort and filter as needed for root cause analysis. AI agents designed for specific use cases can also speed up the process to organize and present data for real-time decision making. These dashboards and views can be tailored for specific users such as project managers, control account managers (CAMs), functional managers, schedulers, finance, material or subcontract management, and others.

Taking advantage of BI and AI does require a defined enterprise strategy to successfully leverage these powerful tools. Data is the backbone of any AI model – data is needed to “teach” AI how to spot patterns and make predictions. This includes the vast volume of an organization’s transaction records, analytics, and proprietary information across multiple systems.

The problem? Organizations often lack a consistent, verified version of data (the single source of truth) – there is uncertainty about what data should be used to analyze and “feed” their AI models. Internal proprietary data must not be exposed to the outside world. The single source of truth must exist in a governed and curated environment; it must be organized and integrated with a defined data model to be able to analyze real-time streams of data while avoiding multiple versions of the truth.

The challenge is that many organizations are still doing their enterprise planning, including estimating, budgeting and many other functions, in spreadsheets. It is not accessible to others or captured in a common database. Employees end up debating discrepancies between spreadsheets rather than analyzing the data in question.

Once the system that contains the official single source of truth has been determined and how data is organized and integrated, there are a variety of commercial off the shelf (COTS) tools available for the next step. Employees (the power users) familiar with BI and AI tools can quickly turn ideas into apps in a matter of hours or days that help them and their team to get things done. They can quickly build business environment specific dashboards, analyze real-time data pulled from various data sets, and produce outputs designed for different users or use cases.

Putting All the Pieces Together

What are the three primary takeaways?

The requirement to provide a fact-based assessment of project progress and forecast isn’t going away. The FAR overhaul didn’t do away with EVMS or the related fundamental requirements. It does, however, require organizations to be efficiently expert at EVM. A “living” EVMS (i.e., actively maintained and used) that can be scaled/tailored to management needs for each project is essential.

Changes to the requirements provides an opportunity to update “bloated” processes and procedures or that haven’t been updated to reflect new tools. Since the EVMS will need to be reviewed anyway to verify it supports the revised guidelines as well as updated agency requirements, there may be non-value added content or steps that can be eliminated.

BI and AI tools are useful for organizing real-time data into actionable information. Organizations taking advantage of these tools can rapidly respond to realized or emerging risks and changing scope or priorities in response to evolving threats. This creates a competitive advantage.

Returning to a Focus on Proactive Management

This is an opportunity to return to the original objective of an EVMS: timely and relevant information for proactive decision making to ensure project success and a happy customer. The effectiveness of an EVMS should be measured by the technical, schedule, and cost performance metrics. Product acceptance and in-process controls are examples of technical performance metrics. Schedule status and forecast, cumulative to date cost performance index (CPI), estimate at completion (EAC), and the to complete performance index (TCPI) are examples of schedule and cost performance metrics.

Too often the perceived approach to a “compliant” EVMS is to drive the data to an excessive level of detail along with restrictive rules and guidance that result in a system that is cumbersome and painful to use. It reinforces the perception that EVMS is too costly – something the customer doesn’t want to pay for because they don’t see the value.

The alternative? An organization that is efficiently expert at EVM where the customer has directly experienced the value of using real-time performance data to successfully manage their program. Non-value activities have been eliminated. An actively maintained and used EVMS is also resilient; project teams can quickly respond to evolving priorities and threats. Taking advantage of the power and agility of BI and AI tools/apps can help project teams to focus on what matters with real-time data and analytics.

Taking Advantage of the Opportunity to Revitalize EVM

Changing the view that EVMS is burdensome, costly, and of no value will take time. It depends upon organizations choosing to become efficiently expert at EVM.

Recent changes in requirements and the guidelines will require organizations to review the state of their EVM Systems. It creates an opportunity to eliminate non-value added activities. At the same time, powerful BI/AI tools enable real-time data analysis so project teams can be more proactive as well as renovate EVMS functions. The effectiveness of the EVMS is apparent because it provides real-time visibility into project performance with a credible forecast completion date and estimate at completion.

There is no need for excessive oversight by government customers that drives up the cost of managing projects when the customer has confidence the organization’s EVMS provides the visibility they need – and that earned value based project management is a valuable tool.

Next Steps

Consider having an independent third party complete a thorough assessment of your EVMS process areas and documentation to identify where content can be trimmed and clarified or where non-value added steps can be removed – particularly if you are starting to integrate BI and/or AI tools into your EVMS and other business systems.

Integrating Subcontractor Data into an Integrated Master Schedule

By / / , , , , , , ,
, , , , , , ,

Generating and maintaining a project’s Integrated Master Schedule (IMS) that meets management needs as well as customer requirements is difficult under the best of circumstances. The challenge becomes even more complex when subcontractor work effort must be incorporated. Issuing a subcontract is, in effect, handing off a portion of the work scope to an outside entity that becomes responsible for performing that work and meeting all technical requirements. 

Another consideration for contractors where Earned Value Management System (EVMS) contractual requirements apply is whether the subcontractor is considered a major subcontractor because of the contract value, scope of work, or high risk factors. The EVMS requirements are flowed down to these major subcontractors; they will have the same contractual requirements and challenges as the prime contractor. Most subcontracts do not fall into this category. Many are small, short term, or firm fixed price (FFP) subcontracts. 

Regardless of the category of the subcontractor, the subcontractors and the prime contractor all need an IMS to plan and coordinate work effort as well to measure progress. Using FFP subcontracts on development projects has the potential to increase risk significantly when expectations for scheduling rigor are not clearly defined. 

A Real World Example

H&A EVM consultants supported a multi-billion dollar development project that illustrates the challenges with integrating subcontractor schedules into a prime’s IMS. The prime contractor had two major subcontractors with EVMS flow down requirements. They also had 22 FFP subcontracts without EVMS flow down requirements. 

These FFP subcontracts were also mission-critical. The prime’s first priority was to define the required schedule format and data content in the request for proposal (RFP) to the subcontractors. Standardization was essential, along with specific instructions to ensure the schedule data could easily be incorporated in the prime’s IMS. 

As the basis for a customized project specification, the team selected the Integrated Master Schedule (IMS) Data Item Description (DID) DI-MGMT-81650, an earlier DID that preceded the Integrated Program Management Report (IPMR) and Integrated Program Management Data and Analysis Report (IPMDAR) DIDs. The requirements were simplified and trimmed to selected sections in the DID for the detailed schedules. The document was assigned a specification number within the prime’s document management system so it could be used for future procurements. 

Early Schedule Submittals: A Wake-Up Call

All the subcontractors dutifully proposed and were awarded subcontracts. The FFP subcontractors were required to submit initial schedules using the scheduling tool of their choice at the end of the first month of performance. To ensure compliance, the prime contractor tied the subcontractor’s first payment milestone to the acceptance (receipt, review, and approval) of their first schedule. 

This turned out to be one of the best decisions made during project startup. 

Those first schedules quickly revealed that many of the lower tier subcontractors had no experience developing logic-driven schedules that could comply with the reduced requirements document. They were unable to generate even the most basic project schedule. It was an eye opener to realize that while the first tier companies and most of the second tier companies did know about project scheduling, some of the second tier and all of the lower tier companies lacked that expertise.

The Solution: A Prime-Led Schedule Development Workshop

The prime’s schedule team, largely comprised of H&A schedulers, quickly initiated a week long on-site workshop open to all subcontractors who wanted help building their IMS. Every one of them signed up as they recognized acceptance of their schedule was a prerequisite for payment. 

Prime contractor personnel were assigned to each subcontractor to help them build schedules that met the requirements. Most of the subcontractors were able to produce an acceptable schedule within the first three days. The other subcontractors required the full week.

The workshop approach provided two major benefits.

  1. The subcontractors gained experience in developing a logic-driven schedule that they could maintain and status. They had a better understanding of what the prime contractor expected them to provide. 

  2. The prime’s schedule team gained a better understanding of each subcontractor’s scope of work and execution strategy. They had a better picture of the entire IMS as well as interdependencies. Without this knowledge, the next step of determining the best strategy to incorporate the subcontractor’s schedule data into the prime’s IMS would have failed. 

Strategies for Incorporating Subcontractor Data into the Prime’s IMS

The NDIA Integrated Program Management Division (IPMD) Planning and Scheduling Excellence Guide (PASEG) is a useful source of information on scheduling best practices. The section on External Schedule Integration offers basic guidance on flowing down detailed scheduling requirements to subcontractors. It also provides a short list of things to consider, such as coordinating dates and change control:

“Status dates should be consistent between the prime contractor and supplier schedules. If the subcontractor’s schedule update is to a different point in time, it could potentially affect the IMS analysis results. If it is not possible to have consistent status dates between the various schedule elements then implement a strict process, with support of all parties, to manage the impacts.

Change control procedures are established and understood. The prime contractor should clearly communicate which type of schedule changes will require pre-approval before incorporation and which type will require coordination only or documentation upon submittal. The lack of a disciplined change control process can result in disconnects between the prime contractor and subcontractor’s schedule.”

Remember the prime contractor’s IMS includes a baseline and a current schedule. The complications can be significant when all the variables are considered such as calendars, mix of schedule tools and options, scheduling techniques, resource loading, and custom fields.

That still leaves the question of how to incorporate the schedule data from an external source into the prime’s IMS. The PASEG outlines three approaches.

  1. Full integration where the entire subcontract schedule is incorporated into the prime’s IMS. 

    Pros: Provides maximum visibility into the critical and driving paths as well as forecast completion dates.

    Cons: Often not feasible with a large number of subcontractors. Mix of scheduling tools complicates the process. 

    Use Notes: This option is often reserved for major subcontractors or teaming partners. Works best when the prime and subcontractor are using a common scheduling tool or the subcontractor has direct access to the prime’s IMS scheduling tool to maintain their data. Otherwise, the prime must incorporate additional processes to import the external data into their IMS. There are other complications, as different schedule tools calculate dates differently, that will need to be handled in the integration process. 

  2. Using interface milestones. 

    Pros: Easier to implement and maintain. Yields the best results with less complex or lower risk subcontractors. 

    Cons: Provides less insight into the subcontractor’s current schedule performance. It does not easily support critical path analysis when paths run through subcontract work effort.

    Use Notes: Requires the manual update of each interface milestone to reflect the latest forecasted dates from the subcontractor’s schedule. The prime must ensure their IMS is properly coded. Contractors often use “External Inbound” and External Outbound” codes along with a subcontractor code and any other codes needed to identify who is receiving/giving to whom.

  3. Representative model. This is a middle ground approach between integrating the entire subcontractor’s schedule into the prime’s IMS and using interface milestones. Requires a summarization or representation of the subcontractor’s work to be entered into the prime’s IMS.

    Pros: Provides a summarized version of the subcontractor work effort that retains enough schedule logic for critical and driving path analysis. 

    Cons: IMS content must be carefully entered and maintained to retain the required relationships to the external schedules for accurate critical path analysis. Requires a higher level of schedule discipline and a defined process to ensure the accuracy of the data between the external schedules and the prime’s IMS. 

    Use Notes: It is often beneficial to provide the subcontractor with a copy of their schedule that includes an extra column that identifies the prime’s task ID that is the “parent” of the summarized or consolidated work. In the initial IMS submission from the subcontractor, the prime added a custom field (Prime Parent ID). That IMS file was returned to the subcontractor, and the use of the special field was agreed upon. In each subsequent submission by the subcontractor, the prime team checked for tasks with no “Prime Parent ID” and added one that would allow integration. This kept the two companies’ schedules synchronized. If changes were made by the prime team that changed the field data in the subcontractor’s IMS, the changes were coordinated. A recommended practice is to group and sort the subcontractor schedule by the prime’s IDs to ensure that it is done properly. 

What Worked for the Complex Development Project

In the situation described earlier, the schedule team determined a hybrid approach was the best solution, depending upon the subcontractor’s scope of work.

  • The full integration approach was quickly eliminated; it was impractical. There were too many schedules, and some were too complex. It would have been a logistical nightmare. 
  • Selected simple FFP subcontract work effort was incorporated using the milestone method. The schedule milestones were carefully aligned to the payment plan milestones so that one set of milestones served both purposes.
  • For the subcontracts with EVMS flow down requirements and the other subcontracts, including some FFP subcontracts, the representative model was used. The prime’s control account manager (CAM), responsible for the subcontractor’s scope of work, was required to condense the subcontract schedule into a representative model that made sense to the CAM. The most common ratio turned out to the 10:1, with 10 subcontractor tasks rolling up to 1 prime contractor IMS task, carefully maintaining the prime’s control account and work package structure. With proper coding, the subcontractor schedule could be easily reviewed and analyzed by the CAM as well as other project personnel.
