Cost control and cost reduction are important processes for businesses. Cost control involves setting targets, monitoring costs, comparing actual costs to standards, and taking corrective action if needed. It aims to achieve cost standards and optimize costs before they are incurred. Main areas of cost control include materials, labor, overheads, sales and energy. Cost reduction identifies and eliminates unnecessary costs to improve profitability. It aims to improve standards through continuous, innovative measures to permanently reduce unit costs. While cost control prevents costs from exceeding limits, cost reduction begins where cost control ends by establishing improved standards and production methods.
