Final answer:
The product itself is not part of a firm's infrastructure, which instead includes the physical facilities, networks of people, and customer service information. Information is the most important commodity in a postindustrial society.
Step-by-step explanation:
The product itself is not part of a firm's infrastructure. Infrastructure refers to the underlying framework necessary for a business to operate efficiently and effectively, which includes elements such as physical facilities like offices and factories, networks of people comprising employees and stakeholders, and pertinent customer service information that ensures adequate support to consumers.
The most important commodity in a postindustrial society is information. This represents the data and knowledge critical for innovation, decision-making, and maintaining competitiveness in a rapidly changing global economy, rather than physical goods or manual labor.
