The markets in scope and customers are derived form the Identified Products and Services. A market channel is the way an organization interacts with its customers. If a market channel is also used for products and services that are out of scope, this can indicate that the scope has to be redefined. Redefining the scope is handled according the procedures in Unified Project Management Method . and may lead to performing the previous tasks again for the added scope items. While identifying the customers and markets, aspects are recognized of the identified customers, markets and market channels that must be maintained in the new situation. Document these aspects as business requirements only if they are not yet documented in the existing Business Requirements Catalogue.
