We call this the &#8220;Shadow P&amp;L.&#8221;<\/p>\n\n\n\n<p><strong>The Equation of Operational Friction<\/strong><\/p>\n\n\n\n<p>To understand if your legacy system is an asset or a liability, you must calculate the <strong>Operational Friction Cost (OFC)<\/strong>. It is not enough to say &#8220;it&#8217;s slow.&#8221; You need to put a price tag on it.<\/p>\n\n\n\n<p><strong>OFC = (T x F x W) + (E x C)<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>T (Time Wasted):<\/strong> The extra seconds\/minutes required to perform a task due to bad UI or system lag (e.g., waiting for a screen to load, manual data entry between two unconnected systems).<\/li>\n\n\n\n<li><strong>F (Frequency):<\/strong> How many times per year this task is performed across the entire company.<\/li>\n\n\n\n<li><strong>W (Wage):<\/strong> The average hourly burden rate of the employee performing the task.<\/li>\n\n\n\n<li><strong>E (Error Rate):<\/strong> The percentage of manual entries that result in data errors.<\/li>\n\n\n\n<li><strong>C (Cost of Correction):<\/strong> The time and money spent fixing those errors (customer support calls, credit notes, re-shipping).<\/li>\n<\/ul>\n\n\n\n<p><strong>Case Study: The &#8220;Free&#8221; Excel Process<\/strong><\/p>\n\n\n\n<p>Consider a logistics firm using a legacy system that doesn&#8217;t print shipping labels automatically.
