The correct answer is D. Individuals who intend to pursue a career as an information-system manager should have technical expertise in information systems, human-relations skills, and the ability to communicate in written form.
Technical expertise in information systems is essential for information-system managers because they are responsible for overseeing the development, implementation, and maintenance of information systems. They need to have a deep understanding of the technologies involved in these systems in order to make informed decisions about their use.
Human-relations skills are also important for information-system managers because they need to be able to work effectively with a variety of people, including employees, customers, and vendors. They need to be able to build relationships, resolve conflicts, and motivate others.
The ability to communicate in written form is important for information-system managers because they need to be able to communicate effectively with others, both verbally and in writing. They need to be able to write clear and concise reports, proposals, and other documents.
In addition to these three essential skills, information-system managers may also need to have other skills, such as business acumen, project management skills, and analytical skills.
