The document discusses common problems faced by SME manufacturers such as low capacity, poor cash flow, delayed customer deliveries, and high inventory. It introduces the Theory of Constraints (TOC) approach to identify the constraints or bottlenecks in a system and leverage them to increase throughput, improve delivery performance, and reduce inventory without additional investment. The TOC approach was applied to an SME client which resulted in significant improvements across various metrics within a short period of time, including a 40% reduction in assembly cycle time and 60% reduction in delays in delivery.
