The P3O® Foundation (2013) manual identifies consistent PPM training through approved providers as a success factor for a Temporary Office model. Section 5.3.3 states, "A critical success factor for a Temporary Office is consistent PPM training delivered by approved training providers to ensure staff competence throughout the office’s lifecycle." This differs from requiring a high P3M3 maturity (B), which is not mandatory, developing templates (C), which risks inconsistency, or lacking culture (D), which is undesirable. The 2013 edition emphasizes training to maintain quality and alignment during the temporary office’s operation. This ensures effective support for programmes or projects, enhancing delivery outcomes.
