Summary
The Service Assurance Lead is a senior role accountable for leading a team of Service Assurance Managers to deliver effective Service Management across assigned D&T Tribes (product, platform, and infrastructure). Embedded within these Tribes, the team acts as the key link between Service Management practices and delivery teams, ensuring adherence to ITIL4, DevOps, and SecOps frameworks while meeting the required service levels for M&S operations and stores.
As ambassadors for Service Management, the team supports Tribe members in balancing delivery velocity with risk mitigation through standardised practices. They proactively monitor performance, identify trends and risks, and work collaboratively with Tribe leadership to deliver insights, root cause analysis, and continuous improvement initiatives. The Service Assurance Lead is responsible for driving performance and maturity across their Tribes and regularly engages with Tribe and business leaders to align priorities, manage risks, and reinforce the value of Service Management.
