You can use internal scoring to measure the different aspects of your service and identify the biggest challenges. This will help you improve customer service quality across all areas by addressing issues as they arise. Set up quality metrics such as average response time, average resolution time, customer satisfaction scores, or average handling times to enable effective business process management. A good idea is also to prepare audit templates and conduct such review sessions regularly. Service quality assurance audits assist in detecting any broken process faster and save some money (since corrective actions can be expensive).
