Name a common customer service metric.

A common customer service metric is the Customer Satisfaction Score (CSAT) because it directly measures how satisfied customers are with various aspects of the service or product they received. This metric is often obtained through surveys where customers rate their satisfaction on a scale, providing valuable insights into their experiences and perceptions.

CSAT is crucial for understanding customer needs and preferences, guiding improvements in service delivery, and helping businesses enhance overall customer experience. By focusing on how customers feel about their interactions, businesses can make informed decisions to improve services and increase retention, which is a central objective of customer service efforts.

The other options, while important for overall business performance, do not specifically measure customer service effectiveness or customer sentiments related to service interactions. For example, net profit margin and sales growth percentage are financial metrics, and employee turnover rate focuses on workforce management rather than customer service directly.
