Theory of Constraints and Supply Chain Management: Operational Efficiency Through Bottleneck Analysis
Overview
This paper examines the Theory of Constraints (TOC) as applied to supply chain management, using the narrative framework of 'The Goal' by Goldratt. It analyzes how identifying and managing bottlenecks in production systems can improve operational efficiency, reduce costs, and increase profitability through better management of operational expenses and inventory.

Introduction
‘The Goal’ is a business novel that follows the journey of Alex, a highly educated and competent manager working at UniCo. Alex is transferred back to Bearington (his hometown) only to realize that the factory is facing a crisis that might lead to a shutdown. Among the problems were a growing production backlog, late shipments, and growing inventory (Goldratt, 1984). The team in the factory does not understand why timely, quality and affordable shipment of products is problematic. After a conversation with his old Physics professor (Jonah), Alex mobilizes his team to actualize some of the professor's thoughts with only three months to turn around the factory, of which the overall 'goal' is to make more and more money. Among the essential concepts that Jonah mentioned include operational expense, throughput, and inventory.
At the time of Alex's arrival at the factory, it was facing a bottleneck along its chain of production. A bottleneck refers to the point of congestion in a system that emerges when workloads arrive quicker than they are processed, leading to congestion of workloads (Barone, 2019). Bottlenecks cause inefficiencies along the production system leading to higher production costs and delays in delivery. To get around the bottlenecks at the company, Jonah defines and relates the mentioned terms as follows.
Operational Expense
Operation expense (OPEX) is an expense incurred by a business during business operations.
