A Program Executive Office may be responsible for a specific program (e.g., the Joint Strike Fighter) or for an entire portfolio of similar programs (e.g., the Navy Program Executive Office for Digital and Enterprise Services). This first version of the directory lists 75 Program Executive Offices and their Program Executive Officers and Program/Project Managers. Combining the budget document with this PEO directory helps you narrow down which of the 75 Program Executive Offices and 500+ program managers to call on.
