On Page xxii of the introduction of „Hoshin Kanri: Policy Deployment for Successful TQM“, Yoji Akao is building the bridge between Deming’s plan-do-check-act and Hoshin Kanri:
„What hoshin provides is a planning structure that will bring selected critical business processes up to the desired level of performance. Hoshin kanri operates at two levels: First, at what Dr. Joseph Juran called „breakthrough“ management or the strategic planning level; and, second, at the daily management level on the more routine or fundamental aspects of the business operation. Hoshin kanri has been called the application of Deming’s plan-do-check-act to the management process.“
