Why are management practices important in digital product and service management?

The correct answer is C. In ITIL Version 5, management practices are sets of organizational resources and capabilities designed for performing work or accomplishing an objective. They are important because they enable and support the organization’s value chain activities and help the organization manage specific aspects of digital products, services, and the wider management system. Each practice combines resources from the Four Dimensions of Product and Service Management, including organizations and people, information and technology, partners and suppliers, and value streams and processes. Option A is incorrect because the organization’s purpose is defined through strategy, mission, governance, and leadership, not by management practices alone. Option B is incorrect because practices do not replace value streams; instead, they support the activities within value streams and value chain workflows. Option D may be partly true in a broad sense, because good practices can influence financial outcomes, but it is not the main ITIL definition or reason. Practices provide the capabilities needed to achieve objectives.
