About this Presentation
This case study explores the application of the Theory of Constraints (TOC) in the linen management system of a major hospital, aiming to improve operational efficiency and reduce costs. As one of the first TOC implementations in a housekeeping sub-system, the study utilized TOC tools such as the Goal Tree, Current Reality Tree, and Evaporating Cloud to identify constraints and develop solutions. Key challenges included high operational costs, inconsistent linen availability, and inefficient replenishment processes. The implementation of the Five Focusing Steps (5FS), along with the replenishment solution, led to significant improvements. The linen system transitioned to a more cost-effective operation with better inventory control and reduced waste. This case highlights the potential of TOC in non-traditional areas of healthcare, demonstrating how systemic thinking and constraint management can enhance service quality, operational performance, and financial outcomes.
What Will You Learn
To help you get the most value from this session, we’ve highlighted a few key points. These takeaways capture the main ideas and practical insights from the presentation, making it easier for you to review, reflect, and apply what you’ve learned.
You’ll discover how TOC transforms linen operations by identifying the true systemic constraint in linen flow — moving beyond inventory counts to focus on bottlenecks that block clean linen availability for patient care.
The session shows how applying Drum-Buffer-Rope and buffer visibility to linen handling turns unpredictable laundry cycles into a coordinated, predictable rhythm that reduces emergency orders and improves service reliability.
It teases that by structuring linen workflow around TOC logic, hospitals can reduce waste, minimize stockouts, and elevate overall hygiene and patient satisfaction without adding staff or inventory.
