Questions & Step-by-Step Solutions
In a project involving tasks X, Y, Z, and W, if W cannot start until Y is completed, and Z can only start after W, which of the following is a valid sequence?
Step 1: Identify the tasks involved: X, Y, Z, and W.
Step 2: Understand the constraints: W cannot start until Y is completed, and Z can only start after W.
Step 3: Determine the order of tasks based on the constraints.
Step 4: Start with task Y, since W cannot start until Y is done.
Step 5: Next, add task W, as it can only start after Y is completed.
Step 6: Finally, add task Z, which can only start after W is completed.
Step 7: Task X can be placed anywhere in the sequence as it has no constraints related to Y, W, or Z.
