The Evolution and Best Practices of Payroll Parallel Testing (PPT)

‍Introduction

Payroll Parallel Testing (PPT) is crucial for ensuring accuracy and reliability during system transitions. This practice has evolved significantly with advancements in payroll technology and increasing regulatory requirements. In this post, we explore the history of PPT, best practices, and how modern solutions like the Nexus Suite Payroll Verification Module can simplify and enhance the process.

Historical Overview

Early Payroll Systems:

‍Payroll was initially processed manually, making transitions error-prone and time-consuming. Early parallel testing mitigated these risks.

Rise of ERP Systems:

‍The 1990s introduced ERP systems like SAP R/3, integrating payroll processes and necessitating PPT to validate new systems against legacy ones.

Cloud-Based Solutions:

‍Modern cloud-based payroll systems, such as SAP SuccessFactors Employee Central Payroll, require rigorous PPT to ensure high standards of accuracy and reliability.

Regulatory Compliance:

‍Increasing regulatory demands highlight the need for precise testing during payroll transitions to ensure compliance and avoid penalties.

Best Practices for PPT

Planning:

‍Early and thorough planning is essential. Adequate planning ensures the successful execution of the PPT and optimal outcomes. Underestimating time and complexity can lead to delays and issues.

Parallel Run Clients or Environments:

‍Set up environments early, considering the entire process from order placement to operational readiness. Ensure security profiles and access are ready, with contingency plans in place.

Data Loads:

‍Clarify who is responsible for loading data, including transaction data entered monthly in the legacy system. Plan for manual data entry if necessary, and assess the risk of not including certain data types.

Resources:

‍Assign clear roles for running payrolls in both systems. Ensure all resources are aware of their responsibilities and have the necessary skills and training.

Payroll Periods:

‍Select a busy payroll month to maximise coverage of pay types. Plan for at least two to three consecutive payroll periods, including retroactive payroll calculations.

Reconciliation:

‍Determine the reconciliation process, whether using a tool or Excel. Ensure users are skilled in using the tool or have a plan for extracting and comparing data in Excel.

Known Differences:

‍Identify and address known differences between the systems early. Decide how to handle discrepancies and set appropriate expectations.

Data Storage:

‍Securely store files for both payrolls and reconciliation data, ensuring appropriate access control.

Entry Criteria:Define and agree on entry criteria before starting the PPT. Meeting these criteria helps avoid delays and ensures readiness.

Reconciliation Process:

‍Plan the reconciliation process, focusing on identifying and resolving differences efficiently. Prioritise resolving significant discrepancies first.

Status Reporting:

‍Provide consistent and accurate updates to stakeholders. Avoid informal updates that might lead to miscommunication.

Exit Criteria:

‍Define and agree on exit criteria upfront to avoid moving goalposts and ensure clear targets for successful completion.
