Final answer:
ERP application software is not one of the foundational building blocks of JIT, which traditionally include Product design, Process design, and Personnel/organizational elements.
Step-by-step explanation:
The question refers to the foundational building blocks of JIT (Just-In-Time), which is a production strategy aimed at improving a business's return on investment by reducing in-process inventory and associated carrying costs. The foundational building blocks of JIT include Product design, Process design, and Personnel/organizational elements. However, ERP (Enterprise Resource Planning) application software is not traditionally considered one of the building blocks of JIT. ERP systems integrate various business processes but are not a foundational element specific to JIT philosophy. Instead, JIT is more closely related to strategies such as continuous improvement and eliminating waste, as well as practical elements like pull systems and flow production.
Therefore, the correct answer to the question - "Which one of the following is not one of the foundational building blocks of JIT?" is E. ERP application software.
