Predictive Supply Chain Methodology (PSCM) marks the transition from reactive and agile operations to a new predictive era. Built on the principle that agility is a by-product of prediction , PSCM unites AI foresight, process control, and human leadership into a single, accountable framework. The methodology reframes operational excellence around anticipation rather than response. It integrates the analytical precision of Lean Six Sigma with the adaptability of Agile, guided by human oversight and ethical validation. Within its predictive DMAIC structure, AI acts as a force multiplier, not a replacement, while leadership ensures that every recommendation aligns with strategy and values. Designed for logistics professionals, executives, and operations strategists, this book defines how prediction replaces reaction and restores balance between technology and human judgment in the modern enterprise.
