U.S. enterprises are advancing their analytics and artificial intelligence strategies by integrating these technologies into core business operations, according to the 2025 ISG Provider Lens® Advanced Analytics and AI Services reports. The research from Information Services Group (ISG) reveals that large organizations are moving beyond isolated pilots to establish unified operating models that embed AI and analytics across decision-making, automation, and performance measurement. As enterprise IT environments grow increasingly complex—with average software portfolios approaching 2,000 systems—data and application fragmentation has become a major challenge. To address this, companies are building unified data foundations and partnering with service providers to modernize data infrastructure, improve governance, and streamline data lifecycle management. AI spending as a share of IT budgets has nearly tripled in the past two years, reaching almost 6 percent, reflecting a shift from experimentation to production-scale deployment. Organizations are now adopting formalized operating models for advanced analytics and AI (AAAI), centralizing leadership, governance, and architecture to ensure consistency and scalability. Midsize enterprises tend to use hybrid models, combining centralized coordination with domain-level autonomy. This allows different business units to progress at their own pace. Service providers are supporting this approach with accelerators, pre-configured data models, and adaptable migration frameworks. Specialist providers are emerging as key partners, particularly in industries with high regulatory or precision demands such as healthcare, financial services, manufacturing, and digital commerce. These firms are focusing on customer data, supply chain telemetry, competitive intelligence, and clinical datasets—areas expected to drive significant business value in the coming years. ISG emphasizes that success in AI initiatives depends on treating data, analytics, and AI as continuous operational capabilities rather than one-off projects. Change readiness, process reengineering, and outcome-based pricing models are also gaining importance. The 2025 reports evaluate 60 providers in the Large and Midsize category across four quadrants, naming Accenture, Capgemini, Cognizant, IBM, Infosys, TCS, Wipro, and others as Leaders in multiple areas. Rising Stars include Coforge and DXC Technology, recognized for their promising portfolios and strong growth potential. In the Specialist segment, Fractal Analytics, Quantiphi, Tiger Analytics, and WNS Analytics are named Leaders in two quadrants each, while Sigmoid is recognized as a Rising Star. Capgemini was named the global ISG CX Star Performer for 2025, based on top customer satisfaction scores in ISG’s Voice of the Customer survey. Customized versions of the reports are available through partners including Atos, Hexaware, Quantiphi, and WNS.
