The documentation explains that CSFs are the areas where things “must go right,” and KPIs are the measures that show whether progress is being made toward achieving a CSF. KPIs should focus on specific performance areas and should be defined so they are SMART and monitored regularly.

For a CSF of “excellent customer service,” appropriate KPIs should reflect customer experience outcomes and customer loyalty/retention. Option C (“number of customers who post negative feedback”) is directly linked to service quality: negative feedback is a clear indicator that customers perceive service failures. Tracking it (and ideally setting a target such as “no more than X per month”) provides a measurable signal of whether service is improving.

Option D (“percentage of customers who renew their annual subscription”) is also strongly linked to customer service because renewal rates are a widely used indicator of customer satisfaction and loyalty: customers who experience consistently good service are more likely to continue their membership. As a KPI, it is measurable, trendable over time, and can be given SMART targets.

The other options are not direct indicators of customer service quality: restaurant ordering (A) is sales/upsell behaviour, fitness improvement (B) is an outcome of training/programming rather than service, and payment method (E) is an administrative preference. Therefore, the best KPIs for this CSF are C and D.
