ERP systems have evolved for decades. In the last 10 years, cloud technology and AI have reshaped how enterprises manage data and operations, moving ERP systems beyond storing and accessing data to a driving force for efficiency and process transformation.
Implementing ERP systems designed for specific functions—such as Workday for human capital and financial management—is a start, but the real challenge for many organizations lies in maximizing the system’s efficiency to achieve the greatest return on investment.
Simply put, many enterprises fail to leverage the full potential of Workday and comparable ERP systems. The challenges they face include data integrity, process improvement and underutilized features.
Cleaning Up Data and Data Integrity
Cleaning up data is the most crucial part of an ERP implementation. Poor data quality can lead to legal issues—for example, incorrect employee or wage data can result in inaccurate IRS filings or payroll tax penalties—as well as frustration among employees and administrators. When moving from legacy systems to a new ERP framework such as Workday, enterprises must delete duplicate records and determine what needs to be migrated to the new system.
To support the data cleanup process, I suggest conducting a data readiness assessment by evaluating legacy data against Workday objects such as Worker, Position, Cost Center and Company. This helps identify gaps between legacy and Workday systems. Any gaps must be rectified by working with data owners, such as contacting employees for missing personal information or administrators for job information.
For large enterprises, it is beneficial to apply transformation logic outside Workday using middleware tools to convert data from legacy formats into Workday formats, which reduces manual errors.
Most implementations load top-of-stack records for all active employees and those terminated in the last few years. Historical transactions are typically not migrated as individual records. Instead, Workday provides free-text fields to load Previous System Job History and Previous System Compensation History on the Worker profile, ensuring a clean start with the new system.
For example, each employee is hired into Workday using current compensation and job details from the legacy system at the time of conversion. Prior job changes, promotions and compensation adjustments are summarized and loaded into free-text fields rather than brought over as effective-dated transactions. This provides visibility into past employment details without cluttering transactional data.
Process Transformation
Whether implementing ERP systems such as SAP, Oracle or Workday, enterprises must focus on true process transformation instead of simply migrating legacy processes. Reducing manual effort as much as possible is key to a successful implementation.
Business processes should be defined with a focus on employee self-service (ESS) and manager self-service (MSS), which allow employees and managers to complete tasks independently without relying on HR personnel. Accessible ESS and MSS capabilities improve employee satisfaction and business efficiency.
As a specialist in business transformation solutions and cloud-based ERP technologies with a strong focus on HR applications, my goal is to architect systems and strategies that drive measurable process improvement.
In one instance, I designed an automation for T2200 forms in Workday. Employees submitted requests through a request framework and entered required data through questionnaires before the form was routed to HR for review. Once approved, an integration collected the data and generated a T2200 form using a fillable PDF and Adobe web services. This automation saved approximately 300 hours of manual HR labor annually for an organization with 500 employees.
In another example, I implemented automation of the 401(k) true-up process. Typically performed by payroll at year-end, a true-up ensures employees receive the full employer match if they reach contribution limits midyear. I configured the match calculation to use year-to-date contributions during each payroll cycle rather than reconciling manually at year-end. This eliminated manual adjustments and saved approximately 80 payroll administrator hours annually for an organization with 2,000 employees.
Implementations Using Standard Setup
Leveraging Workday standard setup can help maximize ROI in several ways:
- Reducing implementation time. Workday provides a range of standard configurations available in the wdsetup tenant that create a strong foundation for implementation. Adding required configuration on top of the standard setup reduces implementation cost and timeline. Using standard setup, implementation partners can complete a human capital management (HCM) deployment for smaller clients in approximately 60 business days, compared with 90 to 120 days for traditional implementations.
- Simplifying future maintenance. Many contributed solutions delivered within the Workday ecosystem assume standard setup, making it easier to update configurations later, particularly when responding to legal changes. For example, secure 2.0 configuration updates can be completed in four to 10 hours when standard setup is followed, compared with 20 to 30 hours in nonstandard environments.
- Improving compatibility with Workday updates. Workday releases updates twice per year and tests new releases based on standard practices. Following standard setup helps ensure smoother compatibility during system updates.
While standard setup is recommended for most implementations, there are cases where it may not fully meet business requirements. Organizations with unique benefits vendor relationships or highly customized processes may require adjustments. In these situations, a hybrid approach that begins with standard setup and modifies it as needed is often the most effective solution.
Using Workday Connector Integrations
Workday delivers prebuilt integrations with many vendors, with options to configure certain fields and integration logic. As a consultant in the Workday ecosystem for nearly a decade, I recommend using Workday standard connector integrations instead of custom integrations whenever possible. Connector integrations are generally well-tested, and Workday maintains required updates in coordination with vendor partners.
Building, testing and deploying a custom Workday Studio integration typically requires approximately 140 hours. In contrast, implementing a Workday connector integration can often be completed in about 60 hours. Using standard connectors reduces integration build costs while improving quality, since these connectors are already tested.
There are scenarios where a custom integration using Workday Studio or Enterprise Interface Builder (EIB) is required. Examples include:
- The target system is not covered by Workday-delivered integrations
- The customer did not purchase packaged integrations
- Customer-specific rules exceed standard connector capabilities
- Real-time or event-based integrations extend beyond the connector framework
In these cases, custom development may be necessary to meet functional requirements.
Implementing Multiple Modules in Workday
Implementing multiple modules within a single ERP system can help centralize data, allowing the platform to serve as a single source of truth and support real-time reporting. Maximizing module utilization also helps reduce training and maintenance costs.
Payroll processing, for example, is most efficient when key modules such as Benefits, Time Tracking and Absence are implemented within Workday. Keeping these modules in the same system enables effective-dated transactions and automated retroactive calculations, improving accuracy and reducing manual effort.
Because data flows between modules within Workday, there is no need to run or validate external integrations, resulting in meaningful time savings. Leveraging Benefits and Payroll together can save one to three hours per payroll cycle, while integrating Time Tracking with Payroll can save an average of one to six hours per payroll period.
Similarly, configuring Advanced Compensation directly in Workday eliminates the need to run integrations to load compensation data. Compensation adjustments and calculations are immediately reflected across related modules, improving efficiency and reducing administrative overhead during compensation cycles.
What This Means for ERP Insiders
Improving ROI is a continuous process. Workday implementations do not deliver maximum value at go-live. As new features are released twice per year, organizations must stay current and continuously evaluate how those capabilities align with business needs. Ongoing optimization determines long-term return on investment.
Alignment between business processes and system configuration is essential.
ERP implementations should not replicate legacy workflows. Aligning Workday business processes with organizational processes, expanding self-service capabilities and leveraging standard functionality help reduce manual effort and improve efficiency across HR and payroll operations.
Strategic use of standard features drives sustainable value. Adopting Workday standard setup, connector integrations and cross-module functionality reduces maintenance complexity and supports smoother updates. When used thoughtfully, Workday becomes more than a system of record—it becomes a platform that improves operational efficiency and enhances the employee experience.
