Summary
In this Nucleus Research Note, analyst Charlotte Belke examines how a large global aerospace and defense manufacturer used Deltek Replicon to streamline time entry and payroll processing — resulting in an 83% reduction in timesheet completion time and freeing five payroll employees to focus on higher-value work.
The Bottom Line
A large global manufacturer deployed Deltek Replicon to replace a legacy time and attendance system that was generating systematic payroll errors and placing an unsustainable administrative burden on its engineering workforce. The prior platform required engineers to complete timesheets manually, which was time consuming and ultimately produced incorrect overtime and shift calculations in approximately nine out of ten cases. After finding no viable internal alternative, the organization selected Deltek Replicon for its ability to support multi-project time entry and automated pay rule processing. Following deployment, the organization reported that individual timesheet completion time declined by more than 83 percent, and the five employees previously dedicated to payroll error correction were redeployed to other roles within the organization. This deployment highlights the value of dedicated, automated time and attendance solutions for organizations managing complex, multi-project workforces at scale.
The Company
Nucleus interviewed a large global manufacturer operating across multiple countries as part of a broader multinational enterprise. The organization employs approximately 25,000 staff within the interviewed business unit alone, a significant portion of whom are engineers whose time is tracked against individual projects and cost centers. Its workforce is structured around varied shift patterns, multiple pay grades, and concurrent project assignments, with employees frequently allocated across three or four active projects within a single shift. The organization’s scale and workforce complexity place substantial demands on time and attendance systems to capture labor data accurately and feed downstream payroll and reporting processes.
“Engineers working across three or four concurrent projects were required to enter each allocation manually, consuming approximately one hour per day in administrative data entry.”
The Challenge
The organization’s legacy time and attendance platform could not support the complexity of its engineering workforce. Engineers working across multiple concurrent projects were required to enter each project allocation manually, line by line. As there was no mechanism to enforce allocation rules or distribute time automatically, the accuracy of submissions varied by individual and by the complexity of each shift. Across a workforce of this scale, the cumulative overhead represented a material loss of productive engineering capacity each period. Additionally, the data quality problems that resulted from this process extended directly into payroll. The organization reported that pay calculations were incorrect in approximately nine out of ten cases, a rate that reflected structural limitations in the platform’s ability to apply shift differentials, overtime thresholds, and project-based pay rules without manual intervention. These were also not isolated errors, as every pay period required a dedicated correction cycle before payroll could be processed reliably.
“Pay calculations were incorrect in approximately nine out of ten cases, requiring five dedicated employees to identify and correct errors each pay period before payroll could be processed reliably.”
The volume of payroll corrections was substantial enough that the organization maintained five employees whose primary function was to identify and resolve time-and-attendance discrepancies before each payroll close. However, the correction layer addressed the symptom but did not resolve the underlying cause, leading to payroll close periods being routinely extended and managers having no reliable visibility into hours worked, overtime exposure, or project-level labor allocation until the correction process was complete. This left the organization unable to identify where overtime was accumulating or respond to labor cost variances before they reached payroll, a constraint that grew more consequential as workforce complexity increased.
The Strategy
Before selecting a new time and attendance solution, the organization reviewed options within its existing technology environment. However, it quickly became clear that no internally available tool could handle the combination of multi-project time entry, automated shift and overtime rule processing, and payroll integration the workforce required. The complexity of the organization’s pay rules, spanning multiple shift types, pay grades, and project-based allocations, ruled out general-purpose systems that performed adequately in simpler environments. In its external evaluation of vendors, the organization prioritized the ability to manage engineers working across multiple concurrent projects in a single shift, automated pay rule processing at the point of entry, and clean integration with existing payroll infrastructure. The evaluation also weighted vendor engagement heavily, treating a vendor’s ability to understand and respond to the organization’s specific requirements during the sales process as an indicator of how the relationship would operate through implementation and beyond.
“The organization assessed internal options before going to market and found that nothing available could handle the combination of multi-project time entry, automated pay rule processing, and payroll integration its workforce required.”
Deltek Replicon was selected because it demonstrated a strong fit with the organization’s use case during the evaluation, including its ability to manage multi-project allocations and apply complex pay rules without manual intervention. Replicon’s pricing was also competitive relative to alternatives evaluated, and implementation was completed in approximately nine months to a year through a direct partnership with Replicon’s team, covering pay rule configuration, payroll integration, and user rollout across the affected workforce. The HR leaders noted that working directly with the vendor rather than through a third-party implementation partner enabled the organization to address pay rule requirements directly with the vendor’s technical team without an additional handoff.
“Deltek Replicon was selected for its immediate fit with the organization’s multi-project, shift-based requirements and its ability to apply complex pay rules automatically, capabilities that competing options could not match.”
Primary Benefits
Through end-user conversations, Nucleus identified the main benefits this manufacturer realized upon deploying Deltek Replicon:
Timesheet Efficiency
Following deployment, the organization reported that time spent completing each timesheet submission fell by more than 83 percent. Deltek Replicon’s rules engine automated project allocation across concurrent assignments, replacing manual line-by-line entry. Engineers working across three or four projects in a single shift no longer needed to reconstruct their allocation from memory, and the steps required to complete a submission decreased substantially. One leader attributed the improvement to both the automation of allocation logic and the simplicity of the submission interface relative to the prior system.
Reallocation of Payroll Correction Overhead
The organization noted that the correction layer added recurring labor cost without addressing the underlying platform limitation. Upon deploying Deltek Replicon, the platform eliminated the manual review steps that had generated the error volume by processing overtime and shift calculations automatically at the point of entry. As a result, managers gained direct access to hours and overtime data through the platform without waiting for a corrected report, and payroll close periods no longer required the same level of manual oversight. Due to this efficiency, the five employees previously assigned to payroll error correction were redeployed to other roles. Nucleus estimates that this translates to approximately $300,000 in annual benefits, as these roles did not need to be refilled.
“Timesheet completion time fell by more than 83 percent following the Deltek Replicon deployment.”
Looking Ahead
The organization has maintained its Deltek Replicon deployment for more than eight years, with leaders noting that the platform continues to meet time and attendance needs. As Deltek develops additional automation and analytics capabilities within the platform, the organization may evaluate those features to incrementally improve the ROI of the project. Overall, the organization’s experience reinforces that long-term value from time and attendance platforms is sustained when the system continues to meet core operational requirements without requiring ongoing intervention. This deployment also reflects a broader pattern Nucleus observes across workforce management investments. Organizations do not always require a full platform replacement to realize measurable operational gains. By targeting time and attendance as the primary pain point rather than pursuing a broader technology overhaul, this manufacturer reduced errors, recovered lost productive capacity, and avoided recurring labor costs that extended well beyond the original problem that drove the decision. The result demonstrates that addressing a single, well-defined operational problem can be a viable path to meaningful returns, without requiring the broader lift of a full platform evaluation and implementation.
“Five employees previously dedicated to manual payroll error correction were redeployed to other roles as automated pay rule processing eliminated the structural conditions that had required a dedicated correction cycle each period, saving approximately $300,000 in annual recurring costs.”
