Final answer:
Strategic actions designed to reduce costs in value chain activities aim to achieve operational effectiveness, a key aspect of improving a company's cost competitiveness. These actions optimize processes and resource use to lower production costs and can indirectly affect other areas such as customer satisfaction.
Step-by-step explanation:
Strategic actions to reduce the costs of internally performed value chain activities and improve a company's cost competitiveness typically aim to achieve operational effectiveness. These actions are focused on enhancing the efficiency of operations, which often involves streamlining processes, implementing cost-saving measures, and optimizing resource utilization. By increasing operational efficiency, a company can reduce production costs, which can lead to a competitive advantage in the market. This does not inherently enhance product differentiation (which is more about providing unique products or services than cost reduction), increase customer satisfaction (although it can indirectly do so through lower prices), or strengthen supplier relationships (although it might indirectly affect negotiations with suppliers).
