The document discusses the importance of sustainable change in organizations and outlines a model for achieving it. Sustainable change is defined as an intervention that truly takes root in an organization as opposed to episodic or quick fixes. The model proposes five prerequisites for sustainable change: 1) building awareness among employees of goals and plans, 2) checking for motivation and desire to change, 3) assessing abilities to implement changes, 4) creating opportunities for employees to get involved, and 5) preparing to provide feedback to sustain efforts over time by reinforcing the first four prerequisites. Following this model increases the odds that change efforts will achieve the desired long-term impact.
