We are a fast-growing, chaotic business. How does the standard 90-day EOS® cycle adapt if our industry landscape shifts so rapidly that our quarterly Rocks are rendered obsolete within six weeks?

This is a common concern for fast-growth companies, but it is usually a symptom of reacting to noise rather than true market shifts. The 90-day cycle is a fundamental human cadence. It is the maximum period of time people can stay focused without losing alignment. If your quarterly Rocks genuinely become obsolete within six weeks, we must look at how we write them. Rocks are priorities, not tactical task lists. They represent the most important strategic achievements required to move the business forward. When a massive industry shift occurs, we do not ignore it. We run it through the IDS® process during your weekly Level 10 Meeting™. If the leadership team collectively agrees that an external market shift has made a Rock completely irrelevant, we kill it. We do not replace it mid-quarter. We adjust our focus to the remaining priorities and handle the shift in our next quarterly session. Constantly changing targets in the middle of a quarter destroys accountability and exhausts your team. The 90-day lock is a discipline. It forces you to say no to distracting shiny objects and yes to execution. My recommendation is to maintain the 90-day boundary and use your weekly meetings to manage the noise.
