The goal of each service process should be an excellent service that satisfies the user and meets the strategic goals of the company. It is usually the result of careful design and delivery of a whole set of interconnected processes, subprocesses, operations, or activities. When it comes to processes, it's not just about the part where the user receives the service. Service providers consistently meet customer expectations, manage the chain of processes from the beginning to the end, whose last link is providing service to the user.
