ITSM (IT Service Management) is the practice of designing, delivering, managing, and improving the IT services an organisation provides to its users and customers. Frameworks such as ITIL, VeriSM, and SIAM give teams a structured way to handle incidents, changes, service levels, and suppliers so that IT reliably supports business outcomes rather than reacting to problems.

ITIL 4 and ITIL (Version 5) are both maintained by PeopleCert with AXELOS. ITIL 4 introduced the Service Value System and the seven guiding principles. ITIL (Version 5), announced in January 2026, is a measured evolution that keeps that foundation while expanding guidance for AI-driven, product-centric, and digital-first operating models. New learners can start with either, and existing ITIL 4 holders can upgrade through the Foundation Bridge.

Yes, ITSM certification is highly valued in Greece across industries such as IT services, banking, telecommunications, the public sector, and consulting. As the Greek ICT market grows at a double-digit rate and organisations accelerate digital public services, cloud, and e-government programmes, employers increasingly look for certified service management professionals to keep those services reliable, secure, and well governed.

Yes, ITSM-certified professionals are generally well positioned in the job market. According to PeopleCert and AXELOS, certified ITIL 4 Foundation professionals report up to 18% higher global median salaries than non-certified peers. Certifications such as ITIL, VeriSM, and SIAM validate practical service management expertise, which employers value when hiring and promoting.

An ITSM certification can open roles such as Service Desk Analyst, Incident Manager, Problem Manager, Change Coordinator, Service Delivery Manager, IT Service Manager, and Service Integration Lead. In Greece, these roles are in demand across banks, telecoms, the public sector, and technology and consulting firms modernising their IT operations.

ITIL 4 Foundation is the best starting point for most professionals, as it teaches the core concepts and vocabulary of IT service management. New learners may instead choose ITIL (Version 5) Foundation to begin on the latest edition. VeriSM and SIAM are typically taken once you have a working knowledge of service management fundamentals.

VeriSM is a service management approach maintained by EXIN that helps organisations deliver services in a digital, Agile, and product-focused environment. It introduces the Management Mesh, which lets teams blend practices and tools to suit each situation. VeriSM Foundation suits professionals who want service management that flexes with modern ways of working.

SIAM (Service Integration and Management) is an approach for managing IT services delivered by multiple suppliers as a single, coordinated service. Maintained by EXIN, SIAM Foundation introduces the roles, structures, and practices needed to integrate providers, while SIAM Professional focuses on designing, implementing, and running a SIAM model in practice.
