Compare and contrast two change theories, and determine which theory makes the most sense for implementing your specific EBP project. Why? Has your mentor used either theory, and to what result?For change to occur and be successful, there must be an appropriate change theory to provide a framework for its implementation, management, and evaluation. Two common change theories are Kurt Lewin and Ronald Lippitt’s change theories. Lewin’s theory identified three stages in which change agents must proceed before change becomes part of a system. These three stages are unfreezing (when change is needed), moving (when change is initiated), and refreezing (when equilibrium is established) (Mitchell, 2013). He also discussed how certain forces can affect change, which he called force-field analysis (Mitchell, 2013). Lippitt’s theory identified seven phases which are (Mitchell, 2013): AssessmentPhase 1. Diagnose the problem Phase 2. Assess motivation/capacity for change Phase 3. Assess change agent's and resources
