What exactly are the "rules" in Technology of Production?

CFAI defines Technology of production as the “rules” of transsformation from factors of productions into final goods/services.

Can I assume what they’re trying to say is Technology of Production means the efficiency of the production process?

In my opinion, ‘rules’ govern a system and relate to work-flow, or the process of taking an object from raw input to finished good. ‘Efficiency’ is the end measurement of that system. However, you basically got the concept - tech is efficienct, production is the rule-order.
