Letting both X and Y run continuously will build up inventory in front of bottleneck X.<\/li><\/ul>\n\n\n\n<p>X \u2192 Y<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>The bottleneck feeds the non-bottleneck.<\/li><li>Y is starved for inventory to process and marches to the beat of X\u2019s drum. This is totally fine, even if Y is idling at times. No inventory builds up in front of Y.<\/li><\/ul>\n\n\n\n<p>X \u2192 Assembly \u2190 Y<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Parts passing through X and Y flow into a joint step of assembly.<\/li><li>Working Y out of pace with X produces inventory in front of assembly.<\/li><\/ul>\n\n\n\n<p>X \u2192 Product A | Y \u2192 Product B<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Here X and Y are independently operating for separate marketing demands.<\/li><li>If X cannot produce enough to meet market demand, then the constraint for product A is bottleneck X.<\/li><li>If Y can produce more than enough to meet market demand, then the constraint for product B is not Y &#8211; it is market demand. Y can produce more than the market demands for the sake of \u201cefficiency,\u201d but this will lead to excess product B inventory, increasing costs.<\/li><\/ul>\n\n\n\n<p>In all these blocks, <strong>Y never determines throughput for the system<\/strong>. Throughput instead is determined by bottleneck X, or market demand.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>The Massive Cost of the Bottleneck<\/strong><\/h3>\n\n\n\n<p>Any time that the bottleneck isn\u2019t working is lost time forever that cannot be made up at any other part in the manufacturing process flow.<\/p>\n\n\n\n<p><strong>An hour lost at the bottleneck causes a loss in total throughput equal to the hourly capacity of that bottleneck. <\/strong>This is an important concept.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>If the total throughput is a thousand dollars per hour, then the bottleneck is processing at a thousand dollars per hour, <em>even if the literal operational costs or the parts going through it cost much less<\/em>.<\/li><li>Alternatively, take the <em>entire <\/em>operating expense of the factory, divided by the hours worked by the bottleneck &#8211; that\u2019s the <strong>actual cost of the bottleneck<\/strong>.<\/li><\/ul>\n\n\n\n<p>In other words, a loss in the bottleneck means a loss to the entire operation, and should be viewed with such gravity<\/p>\n\n\n\n<p>Other losses in <em>effective <\/em>throughput are also similarly costly. For example, feeding low-quality parts through the bottleneck will cause rejection later, leading to effectively lower throughput.<\/p>\n\n\n\n<p>While time lost from the bottleneck can be made up for by hurrying non-bottlenecks, any extra effort here typically adds to operational expenses (eg overtime pay). Ideally, the bottleneck is simply maintained at peak capacity at all times.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is a manufacturing process flow?
