Two-Quarter Warning · the methodology in long form.

By Regan Inkster. The book behind the Phive Dynamics methodology: how coherence (how well intent, reality, and action stay connected) becomes a measurable leading indicator, why the signal precedes the financials by two to four quarters, and what to do before the metrics catch up.

Two-Quarter Warning by Regan Inkster

Organizations do not fail suddenly. They fragment quietly, long before the numbers show it. Two-Quarter Warning introduces Organizational Phi (Φ) as a measurable leading indicator that tracks how faithfully strategic intent transmits from boardroom to frontline. When coherence drops, financial performance follows roughly two quarters later.

The instruments leaders rely on cannot detect this. Engagement scores, OKRs, town halls: they measure sentiment and activity, not transmission fidelity. By the time the quarterly numbers report the danger, the fragmentation happened six months ago.

The book sets out the methodology in full. It explains how to read coherence, and then what actually strengthens it once you can see it. Reading the signal early matters because it leaves time to act while acting is still cheap.
