The P3O® Foundation (2013) manual identifies continuous development of standards through external best practice as a success factor for a Virtual P3O model. Section 5.3.3 states, "A key success factor for a Virtual P3O is the ongoing development of standards by monitoring external best practices, ensuring adaptability and relevance." This differs from hub leadership (A), cultural challenge (C), or cost perception (D), which are irrelevant or negative factors. The 2013 edition highlights this adaptability to maintain effectiveness in a flexible, distributed model. This ensures competitive PPM practices.
