I. MATERIALS MANAGEMENT
MATERIALS – is one of the principal “m’s” of industry, worry controllers, annoy sales managers, plague purchasing agents, haunt production managers, and harass stock-keepers. MATERIAL MANAGEMENT – is a continual struggle between too much and too little,, too soon and too late.

Ex. Machine-tap blank turned from a bar, a shoe upper cut from a leather hide and a sandblasted and painted castings.
D. Finished Products – good completely manufactured and inspected, ready for a shipment to a customer.
Ex. Completed machine tap, a finished pair of shoes, and a decorated cast-aluminum vase.
E. Supplies – Consumable materials used in the manufacturing process which do not become a part of the product.
Ex. Grinding wheels, taps, drills, belting sand paper, oils, sawdust, plating supplies, lumber, shipping cartons, stationary and pencils.
F. Equipment Items – expendable parts of machines and other physical facilities.
Ex. Jigs, Fixtures, fittings, valves, fuses and fluorescent lamps.
III. SCOPE OF MATERIALS CONTROL
Effective control of materials embraces four phases:
