Final answer:
In mature industries with stable demand, firms typically use stable alliance networks to capitalize on synergies and maintain efficiency in their market offerings.
Step-by-step explanation:
In mature industries where demand is relatively stable and predictable, the most likely type of network alliance used is a stable alliance network. These alliances are established between firms with the goal of exploiting existing synergies and capabilities in a predictable market environment. The focus of a stable alliance network is on long-term cooperation, efficiency, and consistency in production and distribution processes, ensuring that partner firms can reliably meet the demands of the market. This differs from dynamic or horizontal alliance networks, which are often sought in rapidly changing or competitive industries, and vertical alliances, which are structured around supply-chain relationships.
