The P3O® Foundation (2013) manual identifies documenting an outline Business Case as an activity in the 'Identify' process. Section 4.3.1 states, "The 'Identify' process involves developing an outline Business Case to justify the need for a P3O and outline initial benefits." This differs from refining the Vision (A), which occurs in 'Define,' or planning tranches (C) and delivering capability (D), which are later stages. The 2013 edition emphasizes this early justification to secure support, guiding subsequent P3O development. This ensures a solid foundation for implementation.
