This document summarizes a Lean Six Sigma project to implement a preventive maintenance program for HVAC systems at Marine Corps Base Camp Lejeune. The project charter defines the problem of high maintenance costs and equipment failures due to a lack of preventive maintenance. The project aims to develop standard operating procedures, prioritize assets, and utilize maintenance management software to minimize failures and costs. Key milestones and an implementation plan are provided to transition the project from improvement to control phases.
