The correct answer is: A critical ratio scheduling determines the status of each activity.
Critical ratio scheduling is a project management technique that helps to prioritize activities and ensure that they are completed on time. It does this by calculating the critical ratio for each activity, which is the ratio of the amount of time remaining to the amount of time that is critical to the project. Activities with a critical ratio of less than 1 are considered to be behind schedule and should be given priority.
Critical ratio scheduling is a dynamic system, meaning that it can be adjusted as the project progresses. For example, if an activity is completed ahead of schedule, its critical ratio will decrease and it will no longer be a priority. Conversely, if an activity falls behind schedule, its critical ratio will increase and it will become a higher priority.
Critical ratio scheduling is a valuable tool for project managers who want to ensure that their projects are completed on time and within budget. It is a simple and effective way to prioritize activities and make sure that the most important tasks are completed first.
Here is a brief explanation of each option:
- A critical ratio scheduling determines the status of each activity. This is the correct answer. Critical ratio scheduling calculates the critical ratio for each activity, which is the ratio of the amount of time remaining to the amount of time that is critical to the project. Activities with a critical ratio of less than 1 are considered to be behind schedule and should be given priority.
- B adjusts automatically changes in activity progress. This is not correct. Critical ratio scheduling does not automatically adjust to changes in activity progress. The project manager must manually update the critical ratio for each activity as the project progresses.
- C is a dynamic system. This is correct. Critical ratio scheduling is a dynamic system, meaning that it can be adjusted as the project progresses. For example, if an activity is completed ahead of schedule, its critical ratio will decrease and it will no longer be a priority. Conversely, if an activity falls behind schedule, its critical ratio will increase and it will become a higher priority.
- D none of these. This is not correct. The correct answer is A.
