SAP HR Test Automation: How a Fortune 50 Agribusiness Reduced Regression Time by 80%

Why the fix wasn't more testers, but a new operating model

When TTC Global partnered with a Fortune 50 global agribusiness, the organisation was running a complex, multi-module SAP HR landscape, and struggling to scale quality alongside an accelerating Agile delivery model. Within 18 months, automated regression coverage exceeded 70% and execution time fell by up to 80%.

The organisation was running a highly integrated SAP HR landscape, covering Employee Central, Payroll, Compensation, and Recruitment, with multiple downstream systems supporting business-critical workforce processes. Releases were frequent, dependencies were complex, and regression cycles were becoming increasingly difficult to manage.

At the same time, the organisation had just transitioned to a centralised Testing Centre of Excellence (TCoE) and an Agile delivery model. The expectation was faster delivery, but the testing capability hadn’t yet evolved to support that pace.

Regression cycles were still heavily manual. Test coverage was inconsistent. And every release introduced uncertainty.

Hiring more testers would not have solved the problem. The testing model itself needed to change.

Shifting From Reactive SAP Testing to a Managed Quality Engineering Mode

TTC Global was engaged as a managed service partner to take ownership of end-to-end SAP HR test delivery. The brief covered three things: stabilise releases, cut manual regression effort, and build a testing capability that could keep pace with ongoing change.

Rather than working as an external team, we embedded directly into the client’s delivery model. Test Managers, Functional Testers, and Automation Engineers aligned to both the TCoE governance structure and Agile product teams. This created a single, consistent quality engineering function across SAP and integrated systems.

From the outset, the focus was on moving away from reactive testing and toward an automation-first strategy. SAP quality engineering combines test automation, risk-based validation, and continuous integration to ensure stable, scalable releases.

Building Stability with an Automated Regression Suite for High-risk HR Processes 

We started by identifying the highest-risk HR processes across Employee Central, Payroll, Compensation, and Recruitment. These became the foundation of an expanded automated regression suite using Tricentis Tosca.

At the same time, TTC Global introduced a risk-based testing model. Rather than attempting to automate everything, we prioritised business-critical flows that delivered the greatest value and stability.

The team introduced structured test data practices to improve repeatability and environment management controls to reduce execution failures. KPI-driven reporting gave stakeholders clear visibility into quality, coverage, and release readiness throughout.

Execution and traceability were integrated into Azure DevOps, allowing testing to align seamlessly with Agile delivery.

Within a few release cycles, the fragmented testing setup had evolved into a structured, scalable quality engineering model. 

Growing Automation Coverage Reduces Regression Cycles from Days to Hours

As automation coverage grew, regression cycles that had previously taken days were completing in hours. Release predictability improved, defects surfaced earlier in the cycle, and the business gained genuine confidence in SAP HR changes going live.

Testing stopped slowing delivery down and began actively supporting it.

Over time, the results became clear:

• 70%+ regression test coverage automated across SAP and integrated processes
• 60–80% reduction in regression execution time
• Faster, more predictable release cycles
• Reduced reliance on manual testing
• Improved governance and visibility across releases

The organisation gained a stable, enterprise-grade SAP HR testing capability that could support continuous change without increasing risk.

Quality Engineering Creates Continuous Coverage

Automation was a key part of what made this engagement work, but the bigger factor was the change in operating model.

By embedding a managed quality engineering service, the organisation shifted from project-based testing to a sustainable, ongoing capability. Regression coverage became continuous, release cycles became more predictable, and the risk attached to each SAP change dropped considerably.

Across the large enterprises I work with, the same pressure keeps surfacing: SAP landscapes are growing more complex, Agile delivery is accelerating, and manual testing approaches cannot keep up.

Quality Engineering as a Service offers a way through, combining automation, governance, and delivery alignment into a single scalable model.

For this Fortune 50 agribusiness, it meant replacing manual regression cycles and release uncertainty with a stable, automation-led SAP HR testing capability and the confidence to keep evolving their landscape without fear of regression. 

Moving From Reactive Manual Testing to Scalable, Automation-Led Quality Engineering

At TTC Global, we work with organisations running complex SAP ecosystems where release cadence is increasing and regression effort is growing. Our focus is on helping those teams move from reactive, manual testing to scalable, automation-led quality engineering that supports continuous delivery.

Whether you're stabilising SAP HR, preparing for transformation, or simply trying to reduce regression effort, the right quality engineering approach can unlock faster delivery with less risk.
