EEFs vs OPAs — what's outside, what's inside
What you'll be able to do
EEFs are weather. OPAs are tools the org gives you to deal with the weather.
- EEF = conditions outside team control (internal or external). Examples: org culture, regulations, currency.
- OPA = plans, processes, templates, history owned by the org. Examples: charter template, lessons learned, risk register starter.
- Both feed into almost every process as inputs.
Every PMBOK scenario assumes a project sits in a context. PMI categorises that context into two buckets. Enterprise Environmental Factors (EEFs) are conditions, not under the team's control, that influence or constrain the project. They can be internal (organisational culture, available infrastructure, marketplace conditions) or external (laws, regulations, currency rates, weather, public-health emergencies).
Organisational Process Assets (OPAs) are the plans, processes, policies, procedures, templates, and historical information that the organisation already owns. OPAs are inside the organisation and can be reused or updated. Lessons learned, templates, configuration management databases, and the contract terms-and-conditions library are classic OPAs.
The fastest exam heuristic: 'comes from outside or we can't change it' = EEF; 'comes from inside and we own it' = OPA. The same item can be either depending on origin — for instance, a regulatory standard is an EEF, but the internal compliance template that interprets it is an OPA.
Key points
- EEF = conditions outside team control (internal or external). Examples: org culture, regulations, currency.
- OPA = plans, processes, templates, history owned by the org. Examples: charter template, lessons learned, risk register starter.
- Both feed into almost every process as inputs.
- When in doubt: can the team change it? Yes → OPA. No → EEF.
