Which is true about "supply chains" and "supply chain management?"

The concept of the "value chains" grew out of the theory that supply chains can be managed effectively.

Human resource, accounting, and information system functions are the primary participants in an organization's supply chain.

"Supply chain" refers to a process beginning with idea generation, includes product design and evaluation, and concludes with the implementation phase.

Supply chain management has become important because of quality improvement and cost savings opportunities.
