ISG Provider Lens™: Workday Ecosystem Services 2025 in APAC, Europe, and the US

This ISG Provider Lens™ quadrant study includes the following four quadrants: Transformation Services; Deployment and Integration Services; Performance and Optimization Services, and Innovation on Workday, providing ISG advisors and enterprise clients information to evaluate their existing vendor relationships and potential engagements.

In 2023 and 2024, Deloitte was recognized as a Leader in all three quadrants in both the United States and Europe. This year’s 2025 study had an additional quadrant—Innovation on Workday – that evaluated providers based on their ability to develop custom applications on the Workday Extend platform. Deloitte also emerged as a Leader in the new region—APAC. In this new report, Deloitte is positioned highest and farthest on the “Portfolio Attractiveness” and “Competitive Strength” axes compared to other providers.

The report states, “Deloitte’s transformation services take a business-first approach that integrates functions such as tax, cybersecurity, legal and finance advisory into Workday-led change programs. This approach enables clients to align their HR and finance transformations with broad operating model changes, rather than treating technology as a standalone initiative.”

“Our Deloitte team is thrilled to once again receive ISG’s global recognition” says Jannine Zucker, Deloitte Global Workday Chief Commercial Officer. “With ISG’s addition of the Innovation on Workday quadrant and the added APAC region, it is an honor to be recognized as a Leader in all four quadrants and three regions for delivering clients best-in-class, industry-leading, innovative AI-driven solutions throughout APAC, EMEA, and the US.”

Below are few analyst comments from the report:

• “Deloitte employs a balanced approach across industries, providing sector-specific solutions that focus on achieving business outcomes by addressing critical workforce and finance strategic priorities.”
• “Deloitte combines technology, analytics and consulting to deliver Workday optimization services that not only improve ROI but also enable continuous innovation aligned to enterprise goals.”
• “Deloitte’s balanced strategy lies in providing sector-specific solutions and focusing on achieving business outcomes by addressing critical workforce and finance priorities.”
• “Deloitte integrates AI and GenAI into Workday services to accelerate time to value, simplify work and reduce costs.”
