Final answer:
OPM provides the framework in which portfolio, program, and project management practices are integrated to achieve strategic objectives, not OMB, which is focused on budgeting and overseeing bureaucracies.
Step-by-step explanation:
The framework in which portfolio, program, and project management practices are integrated to achieve strategic objectives is provided by OPM, which stands for Organizational Project Management. The Office of Management and Budget (OMB) is an office within the Executive Office of the President, but its main focus is on producing the president's budget, overseeing its implementation, and overseeing the executive bureaucracy. OMB also coordinates and reviews federal regulations for the president, as well as delivering executive orders and presidential directives to various agency heads. The integration of management practices to achieve strategic objectives is central to OPM, not OMB.
