A sample answer to question 1

What KPIs would you track to judge how well your customer service department is performing, and how do you use them?

I would use a balanced set across experience, quality and efficiency. For experience, CSAT, NPS and customer effort score, plus first contact resolution and complaint rates. For quality, internal quality assurance scores and compliance results. For efficiency, service level, response and resolution times, abandonment rate, average handling time, occupancy and cost per contact. I would also track colleague measures, such as attrition, absence and engagement, since these usually lead customer results. I would look at them as a set and not in isolation, so that a fall in handling time with a drop in resolution would worry me. I would display the key numbers weekly to the team, review them with team leaders in monthly performance meetings, and use the trends to prioritise actions such as training, process changes or resourcing. Where something moves unexpectedly, I would investigate the cause before reacting.

Common mistake to avoid: Chasing one metric; reporting without actions
