Which term describes a process completed only after the effectiveness of a change has been verified?

The term "Closed-Loop Process" refers to a system in which actions are taken based on continuous feedback and verification. In the context of quality and manufacturing, a closed-loop process is one that includes mechanisms for monitoring outcomes and making adjustments based on those outcomes. This means that after implementing a change, there's a verification step to assess whether the change has achieved the intended effect before finalizing that process.

This systematic approach is crucial in quality management as it ensures that improvements are not assumed to be effective but are instead confirmed through data and analysis. By having a closed-loop process, organizations can continuously refine their operations based on quantifiable results, enhancing overall effectiveness and efficiency.

Other terms, such as "Effectiveness Check," refer to the specific act of verifying outcomes, while "Cause-and-Effect Diagram" and "Design of Experiments" are methodologies used to understand the relationships between variables or to systematically test hypotheses, rather than describing the process of verification itself. In contrast, a closed-loop process encapsulates both the implementation of changes and the subsequent verification phase in a holistic manner.
