Supply management is planning and acquiring the current and future needs of an organization via  A. Strategic Orientation, Cross-functional Groups, Process-driven Approach and Supply base Management.  B. Strategic sourcing, Cross-functional Groups, Process-driven Approach and Supply Base management.  C. Strategic Orientation, Cross-national Groups,Process-driven Approach and Supply Base Management.  D. Strategic Orientation, Cross-functional Groups, Process-driven Approach and Supplier Management

The correct answer is B. Strategic sourcing, Cross-functional Groups, Process-driven Approach and Supply Base management.

Here's why:

• Strategic sourcing is a method of managing procurement processes for an organization. It's about harnessing purchasing power to find the best value in the marketplace.

• Cross-functional groups refer to teams made up of people with different functional expertise working towards a common goal. In supply management, this could include people from purchasing, logistics, quality assurance, etc.

• A process-driven approach in supply management means focusing on improving specific processes to increase efficiency and effectiveness.

• Supply base management involves managing relationships with suppliers and evaluating their performance to ensure they meet the company's needs.

The other options contain terms like "Strategic Orientation" and "Cross-national Groups" which are not typically associated with supply management. Also, "Supplier Management" in option D is a narrower term than "Supply Base Management". The latter encompasses not just suppliers but all potential suppliers in the market.
