ITIL and TOGAF: A Comparison of Two Frameworks

ITIL and the TOGAF Standard originated in different contexts, but today they increasingly coexist within the same organisations. The former is a Service Management model geared towards co-creating value through reliable digital services. The latter is an Enterprise Architecture standard that aligns strategy, capability and technology through principles, models and governance. Together, they help to design change and manage its delivery on an ongoing basis.

ITIL is the most widely used international framework for IT management and digital products and services. The latest version is more focused on value delivery. The ITIL framework takes into account various aspects of IT service management such as risk management, service management costs, customer relations and service strategy.

The TOGAF® framework is a step-by-step method for developing an enterprise architecture using a set of tools. It does not prescribe the models that should be used to represent the architecture, but guides the process. Highly scalable and versatile, it can be used by all types of organisations. TOGAF supports all levels: business, data, application and technology architecture.

The main features of ITIL & TOGAF

TOGAF 10 Edition

• This is the 10th edition of the TOGAF standard: more modular, practical and integrable with agile and product-centric methods.
• It revolves around ADM (Architecture Development Method), architectural governance, principles and deliverables (roadmap, standards, target state).
• It extends the perspective from IT to the entire organisation, including business, data, applications and technology platforms.

ITIL

• It introduced the Value System (VS) and focuses on end-to-end value flows.
• It replaces “processes” with 34 flexible practices (e.g. Change Enablement, Incident, Service Design, Architecture Management).
• It integrates with Agile, DevOps and Lean; it promotes continuous improvement, measurement and service governance.

ITIL and TOGAF: Key similarities

• Iterative and continuous improvement approach: ADM in TOGAF and Continual Improvement Model in ITIL are both inspired by the PDCA cycle.
• Strong focus on governance, principles and policies: Architecture Governance in TOGAF; Governance and Guiding Principles in ITIL’s SVS.
• Integration with modern practices: both support agile scenarios, DevOps and cloud.

ITIL and TOGAF: The main differences

• Perspective
  • TOGAF 10: designing and governing Enterprise Architecture.
  • ITIL: delivering value through reliable services that are improved over time.
• Output
  • TOGAF 10: principles, target architecture, standards, roadmap, capabilities.
  • ITIL: value stream, service catalogue, SLA/OLA, operational practices.

In conclusion, ITIL and TOGAF are complementary: while TOGAF provides the direction and constraints, ITIL implements and continuously improves services. Neither covers “everything for everyone”; both must be adopted and adapted according to sector, maturity and objectives.
