The correct answer is: A. alternative identification.
Computer support to the manager has been least in alternative identification. This is because managers often need to identify a variety of alternatives when making decisions, and computers are not always helpful in this process. For example, a manager might need to identify different ways to improve customer service, or different ways to reduce costs. Computers can be helpful in evaluating alternatives once they have been identified, but they are not always helpful in identifying alternatives in the first place.
Alternative selection is the process of choosing the best alternative from a set of alternatives. Computers can be very helpful in this process, as they can quickly and easily compare the different alternatives and identify the best one.
Problem identification is the process of recognizing that a problem exists. Computers can be helpful in this process, as they can be used to collect data and analyze it to identify potential problems.
Alternative evaluation is the process of assessing the strengths and weaknesses of each alternative. Computers can be helpful in this process, as they can be used to generate reports that compare the different alternatives.
None of the above is not the correct answer, as computer support to the manager has been least in alternative identification.
