Final answer:
Measuring performance against objectives and standards is associated with the controlling function in management, where there's a focus on evaluating and aligning operational performance with set goals. The correct answer is option A.
Step-by-step explanation:
Measuring performance relative to objectives and standards is part of controlling. This managerial function involves monitoring the execution of a plan and making sure that organizational goals are being met.
Managers use this process to ensure that everything aligns with the plan, which may include adjusting strategies to achieve desired outcomes. It is distinct from using technical skills, decision-making, and directing, as controlling specifically deals with the evaluation of performance against predetermined standards and implementing corrective action if necessary.
