ISG operates as a research and advisory firm that focuses on helping enterprises structure, select, and manage technology and business services. Its offerings are used by CIOs, CTOs, sourcing executives, and business leaders to evaluate service providers, benchmark internal performance, and plan sourcing and digital strategies. The firm engages with clients across sectors including financial services, manufacturing, healthcare, utilities, and the public sector, providing insight into global sourcing models and operating structures.
The company’s core advisory work covers sourcing strategy, vendor selection, and contract negotiation for IT and business process services. ISG consultants support clients through activities such as defining requirements, building RFPs, evaluating provider proposals, and structuring Service Level Agreements (SLAs). Governance and managed services advisory engagements focus on helping organizations design operating models, performance dashboards, and governance frameworks for ongoing provider management, with emphasis on risk, compliance, and cost control.
ISG benchmarking services provide comparative data on IT costs, service levels, and productivity metrics. Enterprises use these benchmarks to assess how their infrastructure, applications, end-user computing, and shared services environments compare to peer organizations. Benchmarking engagements usually inform cost-optimization initiatives, contract renegotiations, and transformations of IT service delivery models.
The firm’s portfolio also includes consulting around cloud, automation, and broader digital transformation initiatives. ISG supports clients in assessing workloads for cloud migration (cloud management), evaluating automation opportunities (process automation), and aligning operating models, talent, and sourcing strategies to new architectures. Its research covers areas such as infrastructure services, application development and maintenance, engineering services, and business process outsourcing, mapped to current enterprise technology stacks and delivery models.
ISG produces market intelligence and provider evaluations that classify and compare service providers across multiple domains. These research outputs include structured assessments of providers’ capabilities, portfolio breadth, and client coverage. Enterprises and providers reference this material to understand competitive positioning, evaluate sourcing options, and identify partnership opportunities.
