Deloitte Technology Delivery Center provides IT technology services to Deloitte Member Firm clients across Europe, the US, the Middle East and Africa. We are part of a strongly integrated global network of Deloitte Delivery Centers. Our methods, breadth and depth in capabilities, and experienced teams uniquely position us to deliver solutions, services and projects that traditionally would have been completed onshore.

We have expertise in multiple capabilities across Business Operations (Systems Delivery & Modernization, Cloud & Engineering, Operations Transformation ​), Customer & Marketing (Marketing & Commerce, Digital Customer, Digital Foundry & Operations ​), Enterprise Tech & Performance (SAP, ServiceNow, Anaplan ​), Human Capital (HR Transformation, Organizational Transformation ), and Strategy, Analytics and M&A (Data Modernization & Analytics, AI Insights and Engagement).
