During the 'Do' phase of the Deming Cycle, what is primarily implemented?

In the 'Do' phase of the Deming Cycle, which is part of the Plan-Do-Check-Act (PDCA) framework, the primary focus is on implementing the plan on a small scale to test its effectiveness. This approach allows organizations to execute the new strategy in a controlled environment, enabling them to assess its practicality and gather valuable data on its performance before committing to a larger implementation.

By conducting a small-scale rollout, teams can closely monitor the process, identify any issues in real time, and make necessary adjustments before expanding the approach to a broader audience. This testing is crucial for minimizing risk and ensuring that any unforeseen challenges are addressed early in the implementation phase, thereby increasing the likelihood of success when the initiative is eventually rolled out on a larger scale.

In contrast, the other choices do not align with the specific intent of the 'Do' phase. A full-scale rollout or a finalized plan across all departments would typically occur after the success of the small-scale test has been validated. Reviewing past projects to identify issues does not fit into the 'Do' phase, as this perspective focuses more on historical analysis rather than on active implementation of new strategies.
