Step-by-step explanation:
The strategy defined by gaining competitive advantage through lower costs of operations and lower prices for products is known as cost leadership. This strategy is one of the generic strategies identified by Michael Porter and involves a firm setting out to become the low-cost producer in its industry. The sources of cost advantage are varied and can include the pursuit of economies of scale, proprietary technology, preferential access to raw materials, and other factors.
A company that employs cost leadership will typically enjoy a well-established reputation for offering lower prices without necessarily compromising quality, which usually involves slashing prices in response to competitive threats and sustaining profits despite reduced margins. Cost leadership is distinct from differentiation and focus strategies, where companies seek competitive advantage through unique features or specific market niches, respectively.
