Which of the following is not a category of manpower standard variance?

The category that is not recognized as a type of manpower standard variance is mechanical. In the context of manpower standards, variance categories typically reflect different sources of discrepancies between the expected and actual performance or output.

Technological variance accounts for differences arising from changes or advancements in technology that may affect productivity or manpower requirements. Procedural variance relates to how tasks are performed, including potential inefficiencies in processes or methodologies that can influence outcomes. Administrative variance involves discrepancies due to organizational policies, management practices, or clerical errors that may impact workforce management.

Mechanical, however, does not fit within the recognized categories of manpower variance, as it implies an issue more related to machinery and equipment rather than personnel or workforce management aspects. Consequently, focusing on manpower-related variances naturally excludes mechanical considerations.
