The document discusses selling chain management (SeCM) and its role in transforming customer contact into revenue. SeCM establishes linkages between previously disconnected sales functions and processes to enable new revenue channels while improving existing channels. It analyzes how companies like Cisco have implemented SeCM solutions to better engage customers, increase sales effectiveness, and coordinate team selling across multiple sales channels. However, fully reengineering core sales processes and implementing new business models, as shown by the example of Custom Foot, can encounter challenges integrating technologies with existing workflows.
