The Personal MBA: Master the Art of Business

Kaufman reframes business as a living system—an interdependent network of processes, feedback loops, and environmental pressures. He argues that every successful business functions as a complex system that evolves rather than emerges fully formed. To understand how organizations thrive or collapse, one must study how these systems develop, interact, and adapt under uncertainty and change.

The chapter opens with Gall’s Law, which posits that every complex system that works evolved from a simpler one that worked. Kaufman uses this to reject the illusion of designing perfection from scratch, instead aligning system design with iteration—the practice of building small prototypes, testing assumptions, and improving over time. This evolutionary logic parallels agile development and lean manufacturing, where gradual refinement fosters resilience and realism.

He then introduces key structural elements: flows, stocks, and slack. Flows represent the movement of resources, stocks are the reservoirs that hold them, and slack is the margin that keeps operations stable under stress. The tension between efficiency and flexibility defines system health; too little slack creates fragility, while too much wastes resources. Kaufman links this balance to practical constraints in business, showing how inventory, cash flow, and staffing levels mirror systemic behavior across organizations.

Building on Eliyahu Goldratt’s Theory of Constraints, Kaufman notes that every system’s performance is limited by one critical bottleneck.
