While both positions are vital to a modern tech organisation, Service Delivery Manager and Systems Administrator have fundamentally different daily workflows.
Service Delivery Manager focuses primarily on ensuring IT services are delivered to agreed SLA standards, managing vendor relationships, and acting as the primary escalation point between IT operations and the business using ITIL v4 frameworks. Day-to-day work revolves around chairing weekly service review meetings with internal teams and third-party vendors, monitoring SLA and KPI dashboards in ServiceNow and Jira Service Management, managing major incident escalation and post-incident reviews, producing service reporting packs for senior stakeholders, driving continuous service improvement initiatives, coordinating change advisory board submissions, and managing customer satisfaction surveys and service credit claims.
Systems Administrator focuses on managing, maintaining, and troubleshooting enterprise IT infrastructure across Windows Server, Linux, Active Directory, VMware virtualisation, and hybrid Azure cloud environments to ensure availability and performance. Their time is spent managing Windows Server and Linux server environments, administering Active Directory, Group Policy, and Azure Active Directory, performing routine patching, backup monitoring, and capacity management, troubleshooting hardware and software incidents escalated from the service desk, supporting VMware vSphere and Microsoft Hyper-V virtualisation, configuring DNS, DHCP, and SMTP network services, and contributing to change advisory board processes.
