The P3O Foundation (2013) manual states that a P3O typically consists of permanent and temporary offices. Section 5.1.1 notes, 'A P3O model typically comprises permanent offices, such as the Organization Portfolio Office, and temporary offices, such as Programme or Project Offices, to support the change lifecycle.' This differs from transitioning (A), co-located/centralized (B), or virtual/decentralized (C), which describe specific configurations or states. The 2013 edition highlights this dual structure to address both ongoing and project-specific needs, ensuring flexible support across the organization.
