Business process analysis is the most effective way to determine a mission critical asset in an organization. Business process analysis is a method of identifying, documenting, and optimizing the core business processes that deliver value to the customers and stakeholders. By analyzing the business processes, an organization can identify the assets that are essential for the successful operation and continuity of the business, such as data, systems, personnel, facilities, and suppliers. These assets are then classified as mission critical and prioritized for protection and recovery. References: CISSP All-in-One Exam Guide, Eighth Edition, Chapter 1: Security and Risk Management, page 35. Free daily CISSP practice questions, Question 4.
