Question: 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?

Options:

  1. Y, W, Z, X
  2. W, Y, Z, X
  3. Z, W, Y, X
  4. X, Y, W, Z

Correct Answer: Y, W, Z, X

Solution: 

The sequence Y, W, Z, X respects the constraints that W follows Y and Z follows W.

  4. X, Y, W, Z

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.
  • Task Dependency – Understanding the order in which tasks must be completed based on their dependencies.
  • Project Management – Applying principles of project management to determine valid sequences of task execution.
