See below image for the Assess Plan Improve Cycle diagram. Good assessment follows an intentional and reflective process of design, implementation, evaluation, and revision. The Cycle of Assessment relies on four simple but dynamic words to represent this process: Teach, Measure, Reflect, and Plan & Improve.
Improvement cycles are based on a Plan, Do, Study, Act process. While there are many models for continuous improvement, Plan-Do-Study-Act (PDSA) Cycles provide Implementation Teams with a framework for problem-solving barriers.
Among the most widely used tools for the continuous improvement model is a four-step quality assurance method—the plan-do-check-act (PDCA) cycle: Plan: Identify an opportunity and plan for change. Do: Implement the change on a small scale.
