In short, a five-year plan is a suicidal practice for an ExO. If it doesn’t send the company racing off in the wrong direction, it can present an inaccurate picture of what lies ahead, even in the right direction. The only solution is to establish a big vision (i.e., an MTP), set an ExO structure into place, implement a one-year plan (at most) and watch it all scale while course-correcting in real time.
