An information system can enhance core competencies by which of the following means?

An information system enhances core competencies by encouraging the sharing of knowledge across business units. This process fosters collaboration and ensures that best practices and insights are communicated throughout the organization. When different units have access to shared knowledge and resources, they can leverage each other's strengths, leading to improved innovation, efficiency, and decision-making. This interconnectedness helps in building a stronger, more competitive organization by utilizing the expertise and information that exists in various areas.

While better reporting facilities, educational opportunities for management, and interaction between operational employees and management are valuable aspects of an information system, they do not specifically address the critical impact of knowledge sharing at a cross-functional level. These elements can support or complement the sharing of knowledge but do not inherently create the collaborative environment necessary for enhancing core competencies to the same extent.
