This document discusses applying LEAN principles to optimize Pride International's non-manufacturing supply chain processes from purchase order to payment. It describes Pride International and the consulting firm UHY Advisors. It outlines the challenges with Pride's existing vague and siloed procure-to-pay processes and metrics. The strategy involved defining the problem, measuring performance, analyzing inefficiencies, improving processes, and controlling gains. Key activities included mapping the current state, identifying waste, designing an improved future state, piloting changes, and implementing the new processes while instilling a process improvement culture. The pilot demonstrated improvements in key performance indicators like cycle times, rework, and compliance.
