			<Paragraph>You can use input/output control to judge how efficiently your machines or work centers are operating. You can compare <Link href="/baanerp/ti/glossary/glossary#000328" role="glossary">actual input</Link> with <Link href="/baanerp/ti/glossary/glossary#000331" role="glossary">planned input</Link> to find out when there is not enough work at a work center or machine, which leads to poor productivity. You can compare <Link href="/baanerp/ti/glossary/glossary#000329" role="glossary">actual output</Link> with <Link href="/baanerp/ti/glossary/glossary#000332" role="glossary">planned output</Link> to discover problems at a work center or machine.</Paragraph>
			<Paragraph>The difference between input and output is called the queue, and you can use input/output control to compare the <Link href="/baanerp/ti/glossary/glossary#000330" role="glossary">actual queue</Link> with the <Link href="/baanerp/ti/glossary/glossary#000333" role="glossary">planned queue</Link>. The difference between these is the <Link href="/baanerp/ti/glossary/glossary#000335" role="glossary">queue deviation</Link>. You can also define a <Link href="/baanerp/ti/glossary/glossary#000334" role="glossary">desired</Link> queue (in the <GUIRef href="/baanerp/ti/rou/tirou0101m000#tirou001.dque" role="formfield">Desired Queue</GUIRef> field of the <GUIRef href="/baanerp/ti/rou/tirou0101m000" role="session">Work Centers (tirou0101m000)</GUIRef> session), and compare that with your actual queue. The desired queue deviation is the actual queue minus the desired queue.</Paragraph>
			<Paragraph>An additional performance measure provided by input/output control is the <Link href="/baanerp/ti/glossary/glossary#000337" role="glossary">demonstrated load factor</Link>.</Paragraph>
