According to the PMBOK® Guide, Enterprise Environmental Factors (EEFs) refer to conditions, not under the control of the project team, that influence, constrain, or direct the project. These are categorized into Internal (within the organization) and External (outside the organization).
Internal EEFs (Choice B): These are factors within the entity ' s own environment. Factory location, geographic distribution of facilities, and existing infrastructure are classic examples of internal EEFs. Other examples include organizational culture, structure, governance, resource availability, and employee capability. Since the factory belongs to the organization, its location and capabilities are internal constraints the project manager must work within.
Market Share / Brand Recognition (Choice A): While this is related to the organization, it is generally considered an External EEF (specifically under " Market Conditions " ). It reflects the organization ' s standing in the external marketplace compared to competitors.
Local Government Regulation (Choice C): This is a definitive External EEF. It involves legal restrictions, building codes, or environmental regulations imposed by an outside governing body that the project must comply with.
Industry Research (Choice D): This is an External EEF. It falls under " Academic Research " or " Market Research, " providing data from the external environment that might influence the project’s direction or technology choices.
Understanding whether a factor is internal or external helps the project manager determine the level of influence they might have and where the primary constraints on the project ' s success are originating.
