Final answer:
Pi Kappa Phi's strategic plan's duration is not universally fixed and varies per document; it is commonly between 3 to 5 years, but one should check the fraternity's latest strategic plan for the exact timeframe.
Step-by-step explanation:
The duration of Pi Kappa Phi's strategic plan is typically outlined in the official documentation of the fraternity's long-term goals and initiatives. It consists of three two-year phases: Engage, Invest, and Transform. During the Engage phase, the focus is on attracting and developing members, while the Invest phase focuses on providing resources and support. The Transform phase is about advancing and expanding the fraternity's impact.
These plans can vary in length, but most strategic plans range between 3 to 5 years. It is essential to refer to the most recent strategic plan released by Pi Kappa Phi to obtain the exact timeframe.
