What defines "Operable" equipment in the 3-M System?

The definition of "operable" equipment in the 3-M System emphasizes functionality. It is specifically defined as equipment that can perform its intended function effectively. This includes machinery, tools, or systems that are fully operational and ready to be utilized for their designated purpose without requiring any maintenance or repair at that moment.

Other options present scenarios that do not align with the definition. For instance, equipment undergoing repair cannot be considered operable since it is not functioning as intended during that period. Likewise, while equipment that is frequently updated can be operational, the aspect of being updated does not inherently define its operability. Equipment currently in use may or may not be operable; it could be running but might not necessarily perform its intended function effectively. Therefore, the key element lies in its ability to function as intended, making "A" the clear choice.
