A sample answer to question 1

Which KPIs do you report on as a Service Desk Manager, and how do you stop them being gamed?

I report on first contact resolution, SLA attainment for response and resolution, average handle time, backlog age, abandoned call rate, reopen rate and customer satisfaction through post-ticket surveys. No single figure tells the story, so I read them together. If first contact resolution rises while reopen rate and CSAT fall, analysts are closing tickets prematurely. I guard against gaming by sampling closed tickets each week, calibrating quality scores with the team leaders and avoiding individual targets that reward speed alone, such as handle time. I also track repeat contacts by user and category, because they reveal problems that belong with Problem Management. Monthly, I present trends to the IT leadership team with commentary on causes and actions, not just a dashboard. Our reporting in ServiceNow or Jira Service Management is only useful if the data fields are clean, so I audit categorisation too.

Common mistake to avoid: Quoting one headline metric; Rewarding speed over quality
