A sample answer to question 1

What does a service delivery manager do, and how do you make sure a client or internal customer gets what the contract promises?

My job is to make sure that once a service is live, it performs to the agreed standard and keeps improving. That means owning the relationship with the customer, the delivery team and any suppliers. I start by knowing the contract inside out: scope, service levels, service credits, change mechanisms and exclusions. Then I set up a governance rhythm: daily or weekly operational calls, a monthly service review where we go through performance, incidents, risks and improvement actions, and a quarterly strategic meeting. I track performance against SLAs from the ITSM tool, such as ServiceNow, and I don't wait for the monthly pack to spot problems. I act on early signs like rising ticket ageing. I also keep a service improvement plan with named owners, and I manage expectations honestly, so a customer never learns of a breach from someone else. Ultimately my role is to protect the customer's outcomes while keeping the service commercially viable.

Common mistake to avoid: Describing it as just handling complaints; Relying on the monthly report to spot issues
