Question 49 CEL01 - Chief Engineer - Limited

The Correct Answer is A. **Explanation of Option A (Feedback controls):** Feedback controls (also known as retrospective controls or post-action controls) are designed to measure actions or activities **after they have been completed**. They compare the actual results to the desired standards or goals. If a deviation or error is found, the data is "fed back" into the system to take **corrective action** and adjust future operations or processes. This matches the definition provided in the question: controls that measure activities that have already occurred and implement corrective action if needed. **Explanation of Incorrect Options:** **B) Screening controls:** This term is not a standard, primary classification of managerial controls in the way that feedback, concurrent, and feedforward are. Controls are generally classified by the time they occur relative to the activity. **C) Concurrent controls:** These controls measure and regulate actions **while they are taking place**. They monitor ongoing activities to ensure they are consistent with standards, allowing for immediate corrective adjustments *during* the process, not after it is finished. **D) Feedforward controls:** These controls focus on preventing problems **before** they occur. They anticipate potential issues and ensure that resources (inputs) and standard operating procedures are correct *prior* to the beginning of the activity. They look forward rather than backward.
