Which of the following is generally NOT considered a category of delay?

In project management and construction contexts, delays are typically categorized to identify the responsibilities and origins of various setbacks. The categories that are commonly recognized include "Acts of God," which refer to unforeseen natural events like floods or earthquakes; "Owner-controlled," which includes delays caused by the owner, such as making late decisions or changes in project scope; and "Contractor-controlled," which covers delays that arise from the contractor's actions or management issues.

The choice categorized as "Performance-related" does not align with the standard classifications of delays. This term is more ambiguous and can typically be included in discussions of performance metrics rather than being a clear, defined category of delay. In this context, it generally does not fit within the traditional framework used to analyze delay causes in project management. Therefore, identifying "Performance-related" as not fitting into the common categories makes it the correct answer.
