Creating Knowledge articles and publishing them internally and publicly can help reduce the call volumes and escalations for a new product line. Knowledge articles are documents that provide information or solutions to common issues or questions. By publishing them internally, service reps can access them to resolve cases faster and more accurately. By publishing them publicly, customers can access them to find answers on their own without contacting the support call center. This can reduce the workload and improve the satisfaction of both service reps and customers. Verified References: Service Cloud Consultant Certification Guide & Tips, Knowledge Overview
