A useful way of classifying business processes is to identify and define core, support and management processes. Business process classification is important to be able to develop an effective business process architecture.
Core processes are end-to-end, cross-functional processes that directly deliver value to external clients or intermediaries. Core processes are often referred to as "primary" processes as they represent the essential activities an organisation performs to achieve its goals and objectives, fulfil its mission and attain its vision.
These processes make up what is called the value chain, which is the set of high level, interconnected core processes each of which adds value to the product or service. The value chain creates and delivers the product or service, which ultimately delivers value to customers.
