Recommendation: Pilot the platform that matches your primary need — choose UKG for shop-floor scheduling and attendance fidelity; choose Workday if centralized HCM and advanced analytics are the priority. Start with a single production line pilot and validate CNC-derived cycle times before full rollout.
UKG (Ultimate Kronos Group) formed from the 2020 merger of Kronos and Ultimate Software, inheriting a long heritage in workforce timekeeping and Kronos legacy modules. UKG offers UKG Dimensions and UKG Pro, with UKG Dimensions focused on workforce management and Kronos-style rule engines. Workday is an enterprise cloud provider centered on Human Capital Management (HCM) and financials; Workday HCM emphasizes core HR workflows, talent, and analytics with a rapidly expanding platform approach. Both are SaaS cloud models serving global enterprises; Gartner Peer Insights shows Workday rated ~4.5/5 (769 reviews) and UKG ~4.2/5 (705 reviews), highlighting differences in buyer satisfaction and market positioning (Gartner comparison of UKG vs Workday).
UKG targets operational problems tied to timekeeping, labor rules, union/collective bargaining compliance, exception management, and shift-driven scheduling. Workday targets broader HR problems: single-source employee records, talent management, payroll convergence, and analytics across HR and finance domains. For manufacturing, the key distinction is depth versus breadth: UKG offers deeper shift-rule and attendance mechanics; Workday offers broader HCM workflows and enterprise analytics.
Manufacturing shops require operator workload visibility, accurate cycle/standard times from CNC programs, precise labor utilization metrics, and reliable integrations with ERP/MES. These needs reduce manual interventions, reduce overtime, and increase throughput without hiring. Industry integrations commonly include SAP, Epicor, and Microsoft Dynamics — vendors often provide connectors or APIs for these ERPs. For shop-floor integration standards, many manufacturers use MTConnect or OPC UA to capture machine telemetry — integrating those feeds into a WFM system enables scheduling informed by real machine cycle times. For foundational context on workforce management in manufacturing, see our explanation of what workforce management is.
Time & attendance is UKG’s historic strength; UKG Dimensions and Kronos heritage systems have feature-rich rule engines for pay rules, exceptions, and union contract clauses. Workday HCM handles time collection and absence but often relies on extensible integrations for complex plant-level rules. KPIs to compare include schedule adherence, exception rate, and payroll correction volume. Industry benchmarks indicate mature WFM implementations reduce manual timecard corrections by 60–80% and payroll overpayments by 2–4% annually.
UKG provides advanced shift-template libraries, rule inheritance, and granular qualifications mapping — ideal for multi-skill, multi-shift plants. Workday offers robust scheduling tied to worker profiles and predictive analytics, leveraging HR data for longer-term labor planning. Both platforms support mobile shift swaps and self-service, but UKG’s operator-focused mobile UX is often cited as more streamlined for quick clock-ins and complex shift rules. Predictive labor forecasting capabilities in Workday use people analytics; UKG’s forecasting focuses on operational demand and historical time-series for staffing requirements.
Both platforms integrate with third-party payroll engines and native payroll modules. UKG Pro includes payroll modules, and UKG’s payroll integrations are mature in manufacturing contexts; Workday’s payroll is tightly integrated into its HR core and financials for organizations that standardize on one suite. Evaluate data export capabilities and API endpoints for capturing CNC program cycle times and operator IDs — look for secure REST APIs, bulk export, and webhook support for near-real-time updates.

Integrations typically follow three patterns: direct API-to-MES/ERP connections, middleware-based orchestration (Dell Boomi, MuleSoft, Azure Logic Apps), or machine data collectors that transform PLC/CNC output into standard formats. Middleware options like MuleSoft or Dell Boomi enable mapping of timestamps, operator IDs, and cycle counts to WFM data models, allowing for scheduled jobs or event-driven sync. For enterprise-grade connectivity, confirm whether the WFM vendor provides native connectors or relies on partners — Workday has a broad partner ecosystem, while UKG has long-standing integration partners familiar with shop-floor complexities.
A typical flow: CNC controller emits cycle events (via MTConnect or OPC UA), a machine-data collector timestamps cycles and associates them with an operator badge ID (or job order), middleware enriches the events with shift and station metadata, and the WFM ingests cycle counts and durations to update actual standard times. This enables scheduling systems to use real cycle times rather than estimated program times. For an example of CNC programming improvements saving significant money, see "How Smarter CNC Programming Saved $700k" (/how-smarter-cnc-programming-saved-700k).
Ask vendors about expected latency (real-time sub-second for OPC UA vs batch 5–15 minute sync), supported protocols (MTConnect, OPC UA, MQTT), and whether the WFM platform supports custom endpoints for CNC program outputs. Verify data schema details: timestamps in ISO 8601, operator IDs mapped to HR records, cycle counts, run-hours, and program IDs. For more on the value of live machine data in scheduling, refer to our discussion of real-time data for scheduling. Also review platform security (SSL/TLS, OAuth2) and data retention policies for compliance.
External resources to review standards and integration approaches include MTConnect (MTConnect standard and resources), OPC Foundation descriptions of OPC UA (OPC UA overview), and middleware vendor documentation such as MuleSoft’s platform overview (MuleSoft integration platform).
Both vendors use per-employee-per-month SaaS licensing with module add-ons. Core cost drivers are: number of licensed modules (time & attendance, scheduling, payroll), number of users (including casual or mobile users), integration complexity (custom APIs, middleware), and implementation services. Implementation and professional services often equal 1–2x annual subscription for complex integrations. UKG pricing can be more modular for WFM-first deployments; Workday licensing can be cost-effective if an organization standardizes on HCM, payroll, and finance.
For a 150-employee shop, a conservative example:
SaaS license: $6–$12 per employee per month (varies by module) → $10,800–$21,600/year
Implementation & integration: $25k–$75k one-time depending on middleware and CNC/MES connectors
Ongoing support and change requests: 10–20% of licensing annually Hidden costs include reports/customizations, change management, and training for operators and planners.
Use conservative performance assumptions:
Overtime reduction: 10% reduction on $200k annual overtime → $20k/year
Throughput improvement via accurate cycle times: 3% throughput uplift on $2M revenue → $60k/year
Payroll correction and administrative savings: $15k/year
Payback timeline example: With $30k–$40k annual operational savings and $40k implementation, payback occurs within 12–18 months. For shops facing hiring constraints, investments compound value — see our guide on how to overcome the machinist shortage. Vendors may negotiate multi-year contracts or bundle HR modules to reduce upfront costs; ask for detailed TCO scenarios and references from similar shop sizes.
For vendor pricing benchmarks and negotiation guidance, review third-party industry analyses and procurement guides from sources like Gartner and industry consulting firms.
Implementation phases are generally: discovery, design, data migration, integrations, testing, pilot, and go-live. For mid-market manufacturing shops, expect 8–20 weeks depending on scope:
Minimal (time & attendance only): 8–12 weeks
Full scheduling + MES/ERP integrations: 12–20+ weeks Resources required include a project sponsor, IT integration lead, operations SME, and vendor/partner consultants. Proof-of-concept or pilot lines reduce risk and validate CNC-derived cycle time ingestion.
Both platforms support multi-site deployments with centralized administration and local rule overrides. Workday’s architecture supports enterprise-scale global HR with multi-currency payroll and regional compliance modules. UKG’s strength lies in handling many local shift/union rules within the same tenant. For shops expanding across sites, assess replication of configurations, shared master data, and cross-site reporting.
Support varies by contract; typical offerings include 24/7 critical issue support, tiered SLAs, and regional services. Both vendors maintain certified implementer networks; choose partners experienced with MES/ERP integration. Evaluate sandbox access, upgrade cadence, and training options (train-the-trainer vs vendor-led). Verify security certifications such as SOC 2 and ISO 27001, and request uptime guarantees (SLA 99.9% vs 99.95% depending on tier). Use the RFP checklist items: SLA details, sandbox access, upgrade windows, and data export policies.
For middleware choices, consider Azure Logic Apps documentation (Azure logic apps overview) to plan integration patterns.
Choose UKG if the primary requirement is deep time & attendance, complex union/shift rules, and operator-focused mobile clocking. UKG’s Kronos heritage prioritizes rule fidelity and exception management.
Choose Workday if the priority is a unified enterprise HCM with advanced people analytics, talent management, and HR-finance convergence across multiple global sites. Decision drivers include integration needs with MES/ERP, the depth of scheduling rules required, budget/timeline, and internal IT capability.
For small-to-medium CNC shops that need to capture CNC cycle times, reduce manual timecards, and manage multi-skill shifts: UKG typically provides faster time-to-value.
For larger manufacturers standardizing HR and payroll globally with advanced HR analytics: Workday is preferable.
Confirm supported integration protocols (MTConnect, OPC UA, REST APIs).
Validate sample data flows for CNC-derived cycle times and operator mapping.
Pilot one production line for 6–12 weeks to measure schedule adherence and cycle-time accuracy.

APIs: Both offer REST APIs, bulk export, and webhook support; verify rate limits and payload schemas.
Middleware: Commonly used middleware includes Dell Boomi, MuleSoft, and Azure Logic Apps for transformation and orchestration.
Protocols: Confirm support for MTConnect and OPC UA at the machine-data collector layer; WFM systems typically ingest normalized telemetry.
UKG pros: Exceptional attendance rules, mature scheduling templates, strong mobile operator UX. Cons: Can require specialist implementation for ERP/MES mapping.
Workday pros: Integrated HCM and analytics, strong payroll/finance tie-ins. Cons: Less depth in line-level scheduling rules without partners. Use the table above as a short RFP checklist for must-ask items, and request vendor references from manufacturers of similar size and shop complexity.
For shift-driven shops that need precise time & attendance and advanced scheduling rules, UKG often provides faster operational value. For organizations prioritizing enterprise HCM, centralized payroll, and people analytics, Workday is a stronger fit. The recommended next step for manufacturers is a targeted pilot that validates CNC-derived cycle times and measures the impact on schedule adherence and operator workload.
For many small-to-medium CNC shops, UKG is often the better fit when the top priorities are precise time & attendance, complex shift/union rules, and operator-facing clocking workflows. UKG’s Kronos heritage makes it strong for shop-floor rule enforcement and exception handling, which typically reduces payroll corrections and overtime.
However, if the shop requires enterprise HR consolidation, advanced people analytics, and centralized payroll across many sites, Workday may deliver more long-term value despite higher integration scope.
Neither platform typically connects directly to CNC controllers; integration is usually handled via a machine-data collector or MES that translates CNC outputs into standards like MTConnect or OPC UA. Middleware (MuleSoft, Dell Boomi, Azure Logic Apps) maps machine telemetry (cycle counts, timestamps, operator IDs) into the WFM APIs for near-real-time or batch syncing.
Ask vendors about supported protocols, sample data schemas (ISO 8601 timestamps, operator ID mapping), and recommended partners for MES/CNC integrations before committing.
Implementation timelines vary by scope: a time & attendance-only rollout can take 8–12 weeks, while a full scheduling plus MES/ERP integration and pilot can take 12–20+ weeks. Complex union rules, custom reporting, and multiple sites add time to discovery and testing phases.
Budget for data migration, integration testing, and operator training — pilot one production line first to reduce risk and accelerate user adoption.
Common ongoing costs include integration maintenance, support/managed services (10–20% of annual licensing), training refreshers, and change requests for new rules or reports. Hidden costs can also come from custom reports or additional middleware transactions when scaling data flows.
Include annual maintenance and a reserve for change management in your TCO model to avoid surprises during scaling or operational changes.
Validate by running a parallel pilot: compare machine-derived cycle times and operator punch records against WFM-reported time for a 4–8 week period to identify discrepancies. Use badge-to-machine mapping, reconcile timestamps in ISO 8601 format, and measure KPIs such as schedule adherence, exception rates, and payroll adjustments.
Document integration latency and error rates, and require vendors to provide test scripts and sample payloads for MES/CNC data ingestion during the RFP process.
