Final answer:
The correct answer is C) Leveraging cloud computing and data analytics for real-time decision-making, which allows businesses to scale and make informed decisions essential for competitive advantage in the information economy.
Step-by-step explanation:
The technology and business trend that has enhanced the role of information systems in today's competitive business environment is C) Leveraging cloud computing and data analytics for real-time decision-making. This trend helps both small and large businesses manage their operations more efficiently and scale beyond local markets.
With the use of cloud computing, companies can access scalable resources without the significant upfront investment in infrastructure, while data analytics provides valuable insights into customer behavior, market trends, and operational efficiency, facilitating more informed decision-making. Other options such as reducing reliance on data analytics or isolating information systems would be counterproductive in the current business landscape.
Furthermore, the rise of information technologies has resulted in a transformation of both the economy and the way organizations conduct business. For instance, the shift to an information economy means fewer factory jobs due to automation and the outsourcing of manufacturing jobs due to globalization. In contrast, industries like music and film have moved towards digital production, reducing the costs associated with physical media and leveraging the Internet for distribution, thus illustrating how technology continues to influence and reshape industries.
