Rolled throughput yield (RTY){{cite web|title=Rolled Throughput Yield|url=http://www.leansigmacorporation.com/rolled-throughput-yield|work=Lean Six Sigma Articles|date=5 June 2013|publisher=Lean Sigma Corporation|accessdate=19 September 2013}} in production economics is the probability that a process with more than one step will produce a defect free unit. It is the product of yields for each process step of the entire process. {{cite book |last1=McShane-Vaughn |first1=Mary |title=The ASQ Certified Six Sigma Black Belt Handbook |date=11 January 2023 |publisher=Quality Press |isbn=978-1-63694-025-0 |url=https://www.google.com/books/edition/The_ASQ_Certified_Six_Sigma_Black_Belt_H/ow6qEAAAQBAJ?hl=en&gbpv= |access-date=9 February 2025 |language=en}}
For any process, it is ideal for that process to produce its product without defects and without rework. Rolled throughput yield quantifies the cumulative effects of inefficiencies found throughout the process. Rolled throughput yield and rolled throughput yield loss (RTYL) are often used in Six Sigma.{{cite web|url=http://www.six-sigma-material.com/Rolled-Throughput-Yield.html |title=Rolled Throughput Yield (RTY) |publisher=Six-sigma-material.com |date= |accessdate=2012-06-22}}
