What of the following best describes just-in-time inventory management?
◦ Production inefficiencies arising when production capacity stands idle for lack of materials are minimized by holding a small stock of essentials at all times.
◦ A firm acquires inventory precisely when needed so that its inventory balance is always at, or close to, zero.
◦ Inventory is maintained as a buffer to meet uncertainties in demand, supply, and movements of goods.
◦ A firm minimizes the time lags present in the supply chain by maintaining a certain amount of inventory to use in these lag times.
