Almost every IT team has a tool with queues, priorities and SLAs configured in it. Far fewer have agreement on what a priority one actually is, who may declare one, when the clock starts, or how a recurring incident becomes a problem record that someone eventually closes. The tool implies a system and does not create one.
The symptom is always the same conversation. The dashboard reports ninety-four per cent of tickets meeting their SLA and the client is unhappy, and both are true. What was measured is what was easy to measure; the customer's experience lives in the reclassified tickets, the reopened ones, and the work that never became a ticket at all.
ISO/IEC 20000-1 is the international standard for a service management system, and it is most useful as a structure rather than as a certificate. It forces the questions teams avoid: which services do we actually offer, what does each commit to, who is accountable, and how do we know. ITIL supplies the practices; the standard supplies the frame that makes them auditable.
The three levels follow the job rather than the seniority. Foundation for the vocabulary. Lead Implementer for whoever will build and run the service management system. Lead Auditor for whoever will assess one — including assessing a supplier, which is an increasingly common reason to hold it.
Accredited courseware and examinations are in English; sessions are facilitated in English or French. ISO/IEC 20000 cohorts are scheduled on request rather than on the open calendar — tell us the dates that suit you and we will confirm within a week.
