The percentage is based on a single run, often defined by a designated time frame such as a shift. It could also be determined by a test run to give the production team time to make final adjustments to increase process efficiency before processing a full run.<\/p>\n\n\n\n<p>A satisfactory product is evaluated based on its defined quality parameters. Deviations may require the product to be reworked to meet the standards or scrapped because it is too far out of specifications to warrant repair or rework.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">First Pass Yield vs. Rolled Throughput Yield<\/h3>\n\n\n\n<p>The First Pass Yield metric is sometimes used interchangeably with the term Throughput Yield (RTY or Rolled Throughput Yield). However, a distinction must be made between these two KPIs. <\/p>\n\n\n\n<p>Whereas FPY is calculated using one simple manufacturing time frame and one single process, RTY is calculated by considering the accumulated first pass yield scores during multiple time frames or, more often, when there are multiple stages in the manufacturing process. We look at examples of each below.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_to_calculate_First_Pass_Yield\"><\/span>How to calculate First Pass Yield?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>The basic First Pass Yield formula is simple:<\/p>\n\n\n\n<p class=\"has-text-align-center has-medium-font-size\"><strong>FPY = [Number of good units] \u00f7 [Total number of units entering the process] x 100.&nbsp;<\/strong><\/p>\n\n\n\n<p>For example, if there were a total of 200 units in process and 180 of them were acceptable, the FPY would be 180 \u00f7 200 x 100 = 0.90 or 90%. An FPY score of 100 is almost impossible to achieve. However, the higher the score, the more efficient the operation.<\/p>\n\n\n\n<p>In some situations, minor defects that don\u2019t affect the quality of the product could be considered \u201cacceptable units\u201d and would be used as \u201cgood\u201d in the calculation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Practical calculation examples<\/h3>\n\n\n\n<p><strong>A simple FPY <\/strong>example would be the production of a simple item such as a plastic drink tumbler. The number of tumblers succeeding a quality check is divided by the total number of tumblers manufactured in a production process, divided by 100.<\/p>\n\n\n\n<p><strong>A multi-stage scenario<\/strong> could involve the same plastic tumbler but with an additional stage or process that screenprints a logo on it. Here, the FPY is calculated individually for each stage. Then those FPY totals are multiplied together to get the Rolled Throughput Yield (RTY).<\/p>\n\n\n\n<p>Let\u2019s say the FPY for the tumbler forming was 85% and the logo printing was 95%. The RTY would, therefore, be 0.85 x 0.95 = 0.8075 or roughly 80%.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_importance_of_FPY\"><\/span>The importance of FPY<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n<div class=\"banner-v2\">\n    <p class=\"banner-v2__desc\">Increase production efficiency with MRPeasy<\/p>\n    <a class=\"banner-v2__link\" href=\"https:\/\/www.mrpeasy.com\/sign-up\/\" target=\"_blank\" data-ga-event=\"blog_signup_banner_blue\">Try for free<\/a>\n<\/div>\t\t<style>.banner-v2 {\n    float: right;\n    display: flex;\n    flex-direction: column;\n    justify-content: center;\n    align-items: center;\n    padding: 40px 32px;\n    gap: 16px;\n    width: 356px;\n    height: 205px;\n    background: linear-gradient(199.68deg, #6084E5 13.17%, #5FA7DD 82.1%);\n    border-radius: 4px;\n    margin-left: 12px;\n    margin-bottom: 12px;\n    margin-top: 15px;\n}\n\n@media (max-width: 767.98px) {\n    .banner-v2 {\n         width: 100%;\n         height: 173px;\n         margin-bottom: 0;\n         margin-left: 0;\n    }\n}\n\n.single__content p.banner-v2__desc {\n    margin: 0 !important;\n}\n\np.banner-v2__desc {\n    width: 292px;\n    font-style: normal;\n    font-weight: 700;\n    font-size: 22px;\n    line-height: 29px !important;\n    text-align: center;\n    color: #FFFFFF;\n    margin: 0 !important;\n    order: 0 !important;\n}\n\n.single__content a.banner-v2__link {\n    color: #FFFFFF !important;\n}\n\n.single__content a.banner-v2__link:hover {\n    color: #003557 !important;\n}\n\na.banner-v2__link {\n    display: flex;\n    justify-content: center;\n    align-items: center;\n    width: 181px;\n    height: 51px;\n    padding: 18px 0;\n    border-radius: 4px;\n    background: #003557;\n    font-weight: 700;\n    font-size: 16px;\n    color: #FFFFFF !important;\n    text-decoration: none !important;\n    order: 1 !important;\n}\n\n.banner-v2__link:hover {\n    background: white;\n    color: #003557 !important;\n}<\/style>\n\t\t\n\n\n<p>The First Pass Yield metric is a vital KPI because it gives the manufacturer insight into the overall efficiency of their manufacturing processes. Think of it as a barometer that indicates whether the operation is running smoothly and efficiently, or whether some tweaks should be made to increase product quality and further improve output.&nbsp;<\/p>\n\n\n\n<p><span style=\"box-sizing: border-box; margin: 0px; padding: 0px;\"><strong>The direct financial impacts<\/strong>&nbsp;of maintaining a high FPY include reduced raw material waste for products that must be scrapped and elimination of<\/span> labor costs associated with rework.<\/p>\n\n\n\n<p><strong>Operational benefits<\/strong> include process stability and predictability. Knowing what needs to be done to maintain a high FPY can help a manufacturer better understand how to improve <a href=\"https:\/\/www.mrpeasy.com\/blog\/capacity-utilization\/\" target=\"_blank\" rel=\"noreferrer noopener\">capacity utilization<\/a> and the reliability of production scheduling.<\/p>\n\n\n\n<p><strong>FPY can also be used as a diagnostic tool<\/strong>. Using historical FPY data, a manufacturer can determine various potential problems, including the need to repair or upgrade process equipment. When they get a low FPY score, they can check to see what quality issues they\u2019re having and often track them back to an individual machine or stage in the process. If scheduled properly, repairs can often be made without substantial <a href=\"https:\/\/www.mrpeasy.com\/blog\/production-downtime\/\" target=\"_blank\" rel=\"noreferrer noopener\">production downtime<\/a>.<\/p>\n\n\n\n<p>Finally, <strong>FPY scores can serve as benchmarks for improvement initiatives<\/strong>, including upgrading or replacing defective machinery. Tracking the First Pass Yield allows one to measure the effectiveness of process changes.&nbsp;<\/p>\n\n\n\n<p>For example, increasing line speed often leads logically to increased throughput. However, it may lower First Pass Yield scores instead. In our tumbler example above, an increased line speed could cause out-of-register colors in the logo or air bubbles in the ink, resulting in splotches. This causes defective products. FPY numbers allow the manufacturer to tweak the speed to optimal levels to decrease or eliminate printing errors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"8_ways_to_improve_First_Pass_Yield\"><\/span>8 ways to improve First Pass Yield<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Implement structured improvement practices<\/strong> such as <a href=\"https:\/\/www.mrpeasy.com\/blog\/lean-manufacturing-tools\/\" target=\"_blank\" rel=\"noreferrer noopener\">Lean Manufacturing principles and tools<\/a> or take a Six Sigma DMAIC (design, measure, analyze, improve, and control) approach.<\/li>\n\n\n\n<li><strong>Optimize production processes<\/strong>.
