For an organization at P3M3 maturity level 1, the P3O® Foundation (2013) manual suggests the most appropriate use of project planning software is individual, reflecting its basic process capability. Section 6.2.1 notes, "At P3M3 maturity level 1, organizations typically use project planning software on an individual basis due to limited process integration and collaboration maturity." Collaborative (A), integrated (C), and networking (D) uses require higher maturity levels (e.g., 2 or 3), where standardized processes and data sharing are established. The 2013 edition aligns this with the initial stage’s focus on basic project management, where tools are used ad hoc by individuals rather than across teams. This approach supports gradual improvement toward more sophisticated usage.
