Final answer:
The systems analyst's key role is to act as an agent of change, using IT to drive improvements and achieve business goals. In an information society, a software engineer is more likely to be a person of power compared to a coal miner.
Step-by-step explanation:
The most comprehensive and responsible role that a systems analyst takes on is that of an agent of change. In this role, the analyst does not merely act as a consultant that advises on the best course of action, but instead actively participates in transforming an organization's use of information technology (IT) to improve business processes and support strategic business objectives.
In contrast, when wondering which occupation a person of power is most likely to have in an information society, the answer leans towards software engineer. Software engineers are integral in creating and maintaining the IT infrastructure that powers an information society, making them quite influential in such contexts. Conversely, as industries like coal mining become less central to the economy, the influence of occupations such as coal miners decreases within an information society.
