The IMS status date is the cutoff date through which the Integrated Master Schedule reflects actual progress. It separates recorded performance from the forecast for remaining work. Schedulers also call it the data date, as-of date, update date or, in Deltek Open Plan, Time Now.
The status date is not automatically the date someone opens, saves or submits the schedule. Instead, it identifies the point in time at which the schedule update is valid. Every activity should present a consistent picture relative to that point: actual performance belongs on the historical side, while uncompleted work belongs on the forecast side.
This date is central to maintaining a credible Integrated Master Schedule. It affects schedule calculations, critical-path analysis, variance analysis, earned value reporting and management decisions.
What Does the IMS Status Date Mean?
The U.S. Government Accountability Office Schedule Assessment Guide defines the status date, or data date, as the date of the latest schedule update. It establishes the boundary between actual work performed and remaining work.
In practical terms, the status date tells the reader, “This schedule contains progress information through this cutoff.” Therefore:
- Completed activities should have actual start and actual finish dates no later than the status cutoff.
- In-progress activities should have an actual start, a defensible remaining duration and a forecast finish.
- Unstarted activities should remain in the future unless the scheduler documents and corrects an exception.
- Actual dates should not appear after the status date.
- Remaining work should not remain stranded before the status date.
The NASA Program Planning and Control Glossary provides a similar definition. It describes the status date as the date up to which progress is included in the schedule update and the demarcation between actual and remaining work.
Status Date Versus Other Project Dates
Several dates may appear during an update cycle. However, they do not serve the same purpose.
Current date
The current date is today’s calendar date. It changes each day. The status date remains fixed until the scheduler intentionally advances it.
For example, a team may collect Friday’s progress on Monday morning. Monday is the current date, but Friday remains the status date because the update represents performance through Friday.
File save date
The save date only shows when someone last saved the file. It does not establish the schedule’s reporting cutoff. A schedule saved on April 7 could still contain status through March 31.
Report submission date
The submission date is when the contractor or program office delivers the report. Teams often need several business days after the cutoff to collect status, perform quality checks and prepare the schedule narrative. Therefore, the submission date commonly falls after the status date.
Baseline date
Baseline dates represent the approved plan used to measure performance. The status date advances as execution continues, but the baseline should remain controlled. Updating status does not, by itself, authorize a baseline change.
Forecast dates
Forecast start and finish dates describe the current expectation for remaining work. The scheduling engine recalculates them from the status date, activity logic, remaining durations, calendars and constraints.
Is an IMS Status Date a Contractual Requirement?
A status date is necessary for a meaningful schedule update. However, schedulers should not present one universal cutoff convention as a FAR or DFARS requirement.
The governing requirement depends on the contract. Review the Contract Data Requirements List, applicable Data Item Description, statement of work, Integrated Program Management Data and Analysis Report tailoring, reporting calendar and approved Earned Value Management System procedures.
For contracts containing DFARS 252.234-7002, Earned Value Management System, the contractor must use management procedures that generate timely, reliable and verifiable information for the reports and IMS data items required by that contract. The clause does not establish a single status date for every DoD program. The contract’s reporting requirements and incorporated data items provide the applicable details.
As a result, monthly status at the accounting-period cutoff is common on Earned Value Management System contracts, but it is not a universal rule for every IMS. Some programs update weekly, biweekly or monthly. Others maintain internal weekly updates while delivering a formal monthly IMS.
How Programs Select the Status Date
The selected date should match the reporting period represented by the update. More importantly, all contributing organizations should understand the cutoff convention.
A sound status-date procedure addresses the following questions:
- What is the final day or time covered by the progress collection?
- Does the schedule date align with the accounting calendar when EVMS reporting applies?
- Do subcontractor and supplier schedules use the same cutoff?
- If status dates differ, how will the prime contractor reconcile and disclose the difference?
- Does the scheduling tool treat the entered date as the end of a reporting period or the first point at which remaining work may occur?
- Are schedule calendars and time-of-day settings consistent?
The last two questions matter because software products can handle the boundary differently. A date-only display may hide a time value, and different tools may treat the same displayed date differently. The scheduling procedure should define whether status is complete through the end of the selected day or whether the entered date marks the beginning of the next forecast period.
Why the IMS Status Date Matters
It establishes a valid current schedule
Without a recorded status date, reviewers cannot determine when actual performance ends and the forecast begins. They also cannot reliably judge whether activities are late, on time or planned for future execution.
It supports critical-path analysis
The critical and longest paths should originate from current, uncompleted work and continue through the remaining network. If incomplete activities remain in the past, the calculated path may not represent the real execution sequence.
Likewise, future actual dates distort history. Both conditions can produce unreliable float values, forecast dates and downstream impacts.
It supports schedule variance analysis
Baseline-to-current comparisons depend on a stable as-of point. The scheduler needs to know which milestones should have finished by the cutoff and which activities should have started.
Therefore, an incorrect status date can distort milestone variance, baseline execution metrics and period-over-period trend analysis.
It aligns schedule and earned value data
On an EVMS program, the schedule and cost system should describe performance through a compatible reporting cutoff. Planned Value, Earned Value, actual costs, milestone status and forecast dates need a coherent as-of basis.
This alignment supports a reliable Performance Measurement Baseline and improves the quality of management analysis. However, the accounting calendar, contract requirements and approved system description determine the specific implementation.
How Scheduling Software Uses the Status Date
Microsoft Project
Microsoft explains that its status date supports project reporting, progress placement and earned value calculations. The software can use the date when placing actual and remaining work, depending on the calculation options selected.
The official Microsoft guidance for setting the status date also explains that users may set the date to a previous reporting cutoff. For example, a scheduler preparing a report on Monday can retain the prior Friday as the status date.
Microsoft Project users should verify the calculation options that control how completed and remaining task portions move around the status date. Setting the date alone does not replace a controlled status process. The scheduler must still enter actual dates, update remaining duration and reschedule uncompleted work where appropriate.
Deltek Open Plan
Deltek Open Plan uses the term Time Now for the project status date. According to Deltek’s activity-progress guidance, Time Now identifies the date for which progress data has been reported. Open Plan does not schedule future work before that point.
Open Plan documentation also makes clear that Time Now does not have to match the actual current calendar date. This distinction allows a team to process and analyze an update after the formal cutoff.
Deltek Cobra
In Cobra, the status date connects the current reporting period to the project calendar and earned value process. Therefore, the Cobra status period should remain synchronized with the schedule and accounting cutoff used for the update.
A mismatch between the IMS status date and Cobra’s current period can place schedule progress and earned value in different periods. Program controls should reconcile those dates before calculating results or producing customer reports.
Practical Example: Statusing an Avionics Upgrade IMS
Assume the fictional Falcon Ridge avionics program updates its IMS every Friday. The reporting cutoff is Friday, May 29, but the scheduler begins processing the update on Monday, June 1.
The IMS status date remains May 29. The scheduler collects the following information:
- Software Build 4 completed on May 27.
- Laboratory integration started on May 26 and has eight working days remaining.
- The test readiness review did not occur as planned on May 28.
- A supplier interface file will arrive on June 3.
The scheduler enters the software activity’s actual finish as May 27. Next, the scheduler records the laboratory activity’s actual start and updates its remaining duration to eight days. Because the review did not occur, it cannot remain shown as an uncompleted May 28 milestone. The scheduler reschedules it through network logic or updates the forecast based on the program’s approved scheduling procedure.
The supplier delivery remains forecast for June 3 because it occurs after the cutoff. It must not receive an actual finish simply because the team expects delivery.
After recalculation, the test readiness review moves to June 10 and the qualification test finish moves three working days. Management can now see the effect of current performance. The update does not hide the delay by changing the baseline or entering unsupported progress.
Recommended IMS Statusing Sequence
A disciplined sequence reduces inconsistent status and accidental changes to the plan. For a detailed workflow, see how to status an Integrated Master Schedule.
- Confirm the cutoff. Establish the status date and reporting-period convention before collecting progress.
- Freeze the prior update. Retain an archived copy for comparison, reconciliation and audit support.
- Collect objective status. Obtain actual starts, actual finishes, remaining durations, forecast information and explanations from responsible activity owners.
- Set the software status date. Confirm the displayed date, time value and project calendar behavior.
- Update actual performance. Record actual dates and status only when supported by progress records.
- Estimate remaining work. Ask for the duration or work needed to complete each in-progress activity. Do not rely only on a subjective percent complete.
- Recalculate the network. Apply the scheduling engine and approved progress-handling settings.
- Resolve invalid conditions. Correct future actuals, incomplete work in the past, missing logic and unexplained out-of-sequence progress.
- Analyze results. Review milestone variance, critical and near-critical paths, float changes, forecast movement and emerging risks.
- Reconcile related systems. Align the IMS with EVMS, risk, configuration and reporting data as required.
- Document the update. Prepare a narrative that explains significant changes, assumptions and exceptions.
Common IMS Status Date Mistakes
Using today’s date by default
The update should reflect its stated reporting cutoff, not the day the scheduler happens to process it. Automatically using today can create future actuals or make the reporting periods inconsistent.
Treating the filename as the status date
A filename such as “April IMS” does not prove the schedule contains status through April 30. The date must exist in the schedule and agree with the update documentation.
Leaving incomplete work in the past
An unstarted or unfinished activity left entirely before the status date represents work the schedule says should already have occurred. The scheduler should update the activity and let valid logic calculate a realistic forecast.
Entering actual dates after the cutoff
An actual start or finish after the status date implies that the schedule contains knowledge from beyond its declared as-of point. Correct the date, advance the cutoff through the applicable period or document a valid tool-specific convention.
Changing the baseline during routine status
Statusing records performance against the plan. Replanning changes the current approach for remaining work, while rebaselining changes the approved measurement plan through formal control. These actions are related, but they are not interchangeable.
Failing to align schedule and EVMS periods
If the IMS reflects one cutoff while the cost system reflects another, schedule and earned value indicators may tell different stories. This weakens analysis even when each system appears correct on its own. Strong integrated project controls depend on a common reporting basis.
IMS Status Date Quality Checks
Before releasing the schedule, verify that:
- The status date appears in the schedule file and update documentation.
- The cutoff agrees with the reporting calendar or any difference is explained.
- No actual start or finish occurs after the accepted cutoff.
- No incomplete activity remains entirely in the past without a documented reason.
- Every in-progress activity has an actual start and realistic remaining duration.
- Completed activities contain valid actual starts and finishes.
- The calculated critical or longest path connects current work to the key completion milestone.
- Changes from the prior update are traceable and explained.
- The EVMS status period is consistent when earned value reporting applies.
- The schedule narrative uses the same as-of date as the IMS.
Frequently Asked Questions
Is the IMS status date always month-end?
No. Month-end or an accounting-period cutoff is common on monthly EVMS programs. However, the contract, CDRL, reporting calendar and internal procedures determine the required date and frequency.
Can the status date be earlier than today?
Yes. In fact, that is common. Teams often need time after the cutoff to collect progress, update the schedule, perform analysis and prepare reports.
Can the status date be in the future?
A future status date is generally inappropriate for an execution update because actual progress through that date does not yet exist. A planning model may use a future reference date for a specific purpose, but the team should not present it as current actual status.
Is percent complete enough to status the IMS?
Usually not. A credible update also needs actual dates, remaining duration or remaining work, forecast information and valid logic. Percent complete alone may conceal whether an activity can finish as forecast.
Does advancing the status date change the baseline?
No. Advancing the date updates the schedule’s current reporting point. Baseline changes require the program’s authorized change-control process.
The Practitioner’s Interpretation
The IMS status date is more than a vertical line on a Gantt chart. It is the control point that makes the schedule analytically coherent. It tells management exactly when historical performance ends and the forecast begins.
A reliable update uses one understood cutoff across activity status, network calculations, earned value data and management reporting. When teams manage that cutoff consistently, the IMS can support realistic forecasting, performance analysis and timely decisions. When they do not, even a detailed schedule can present a misleading view of program execution.
