The document outlines the Plan-Do-Check-Act (PDCA) cycle, a four-step model for carrying out change. The four steps are: 1) Plan - establish objectives and processes; 2) Do - implement the plan; 3) Check - analyze results and identify variances; 4) Act - identify causes of variances and determine corrective actions. The goal of repeating this cycle is continuous improvement by evaluating the results of change implementations and using lessons learned to further enhance processes.
