Each task began with a <strong>WBS Code<\/strong>, the lineage of work. For each, he calculated <strong>Effort Hours<\/strong>, the heartbeats of human and machine effort. Next, he entered <strong>Resource Quantity<\/strong>\u2014how many minds or machines would carry the task forward. <strong>% Available<\/strong> was the wind\u2014how much of each resource could actually sail. Then came <strong>Performance Factor<\/strong>, a measure of skill and speed, the soul of efficiency.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With the formula:<br \/><strong>Duration = (Effort Hours \u00f7 (Resource Quantity \u00d7 % Available \u00d7 Performance Factor))<\/strong>,<br \/>Thalen conjured the <strong>Duration Estimate<\/strong>, revealing how long each thread would truly take.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Sky Loom rose not from guesswork, but from precision.
