While both positions are vital to a modern tech organisation, Network Administrator and Service Delivery Manager have fundamentally different daily workflows.
Network Administrator focuses primarily on managing day-to-day operation, configuration, and maintenance of LAN, WAN, wireless, and SD-WAN network infrastructure, ensuring network availability, performance, and security across the enterprise. Day-to-day work revolves around monitoring network performance with SolarWinds and PRTG, configuring and troubleshooting Cisco and Juniper switches and routers, managing firewall rules and VPN configurations, responding to network incidents, performing firmware updates and change management tasks, documenting network configurations, managing SD-WAN deployments, and supporting IT projects requiring network connectivity planning.
Service Delivery Manager focuses 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. Their time is spent 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.
