General or Detail
When you grasp a general knowledge and understanding of the factory and become aware of its fundamental rules, and comprehend its principles, you can easily understand its details if you want to. Since minor affairs are branches of the general rules, when you become aware of the general principles, it would be easy to move on to details. For instance, when you know that the factory must function at a specific pace and produce a certain number of products, then you can easily perceive the power of a given wheel, or why it has been constructed in that specific size, or how long it may take this wheel to rotate. In any case, any knowledge of the details is a subsidiary of the general information, and when one becomes aware of the general knowledge, becoming familiar with the details becomes easy.
