3 Stages to Lewin’s change theory:
- Unfreezing
From Lewin’s perspective, the first stage in helping people adapt to change involves unfreezing or loosening their attachment to their current attitude or practice. That means helping them understand why change is necessary and clarifying how the change will be accomplished.
When implementing a change in health care, this stage might include communicating with staff and sharing external research or internal data about the change. It may also focus on training or the distribution of resources that will help people understand the need for the change.
- Change
In the second stage, the process of change actually occurs. This may be a difficult time for individuals affected by the change. These people will need lots of support as questions and frustrations arise.
3. Freezing
Once the changes occur or something has transitioned to a new way of being, Lewin identifies a need to actively “re-freeze” the process in its new state, so that it can continue to operate as designed. This ensures that people will not naturally return to the old way of doing things. This re-freezing may involve new protocols and procedures, periodic process checks to learn how the new process is working in relation to its design, and reinforcement through internal communications and other formats that remind people of the new process.
- Explain the general purpose of the failure mode and effects analysis (FMEA) process.
- Describe the steps of the FMEA process as defined by IHI.
- Complete the attached FMEA table by appropriately applying the scales of severity, occurrence, and detection to the process improvement plan proposed in part B.
Note: You are not expected to carry out the full FMEA.
