According to the PMBOK® Guide, a project manager must navigate two primary types of internal and external factors: Organizational Process Assets (OPAs) and Enterprise Environmental Factors (EEFs).
Understanding OPAs: Organizational Process Assets are the plans, processes, policies, procedures, and knowledge bases specific to and used by the performing organization. These are internal to the organization and include:
Processes and Procedures: Standardized guidelines, work instructions, proposal evaluation criteria, and performance measurement criteria.
Corporate Knowledge Base: Historical information, lessons learned repositories, and project files from previous initiatives.
Why it impacts outcomes: OPAs provide a " head start " for projects. By following established processes and policies, the project manager ensures consistency, complies with organizational governance, and avoids " reinventing the wheel. " Conversely, if these assets are outdated or poorly followed, they can negatively impact the project ' s efficiency and success.
Analysis of other options:
Legal restrictions (Option B): These are Enterprise Environmental Factors (EEFs). They are typically external constraints (laws, regulations) that the project must follow but does not own or control.
Infrastructure, resource availability, and employee capability (Option C): These are internal EEFs. They represent the " conditions " under which the project operates (e.g., the quality of the building, the skills of the available staff), rather than documentation or knowledge assets.
Financial considerations (Option D): These are also considered EEFs. Market conditions, currency exchange rates, and regional price fluctuations are environmental factors that influence project success from the outside.
Per PMI standards, the key differentiator is that OPAs are typically the " tools and documentation " the organization provides to help you, while EEFs are the " circumstances and constraints " you must work within.
