An onion diagram is a kind of chart that shows the dependencies among parts of an organization or process. The customer solution onion diagram illustrates items in concentric circles. Here the items in each ring depend on the items in the smaller rings. A free customizable solution onion diagram template shows different aspects of providing a solution to the customers. As per the image, there are three major departments that can provide solutions to a customer’s problem: service department, delivery management, and customer acquisition. Professional skills and policies/affairs fall under service development; technology and public relations fall under-delivery management, and database and process specification fall under customer acquisition.
