About Us

プロノイア・グループとは?
私たちについて 私たちは「戦略はある、でも実行されない」
という経営層・人事・現場リーダーの悩みに向き合い、組織内に存在する“見えない壁”—空気・誤解・沈黙・遠慮—を可視化し、構造と行動を再設計する専門家チームです。
特に私たちは、現場と経営の間にある“ずれ”にアプローチし、
経営層の意図や戦略を、現場の動きや習慣に変換する「カルチャー実装支援」と「リーダー育成のしくみ化」に強みを持っています。
目標設定が形骸化している。1on1がうまく機能していない。マネージャー層が受け身のまま止まっている。こうした“実行の詰まり”をほどき、組織に合ったマネジメント習慣や意思決定の流れをデザインすることで、変化を止めない組織文化を構築します。
実務と現場に根ざした「文化と行動の再設計」。それが私たちの専門領域です。
