Final answer:
The industrial engineering and account analysis methods are used for determining manufacturing efficiency, focusing on production processes and financial record classification, respectively.
Step-by-step explanation:
The industrial engineering method and the account analysis method are judgment-based methods of determining manufacturing efficiency. In broader terms, these methods are used to evaluate different cost behaviors within a company, aiding in the budgeting and cost management processes. The industrial engineering method involves a detailed study of production processes to establish standards and improve efficiency. In contrast, the account analysis method reviews financial records to classify costs as variable or fixed.
These methods differ from one another in their approach. The industrial engineering method is more hands-on and grounded in the physical aspects of manufacturing, while account analysis is more of an accounting-focused method, looking at a company's books and past financial data. Both aim at improving operational efficiency from different perspectives.
