How to Link unrelated tasks in Microsoft Project, Hammock Tasks
Hammock Tasks. Sometimes, you may want to link two tasks that are not directly related, but depend on the same external factor. For example, you may have a task that represents the duration of a contract, and another task that represents the payment of a milestone. These two tasks are not related in terms of work or resources, but they both depend on the contract start and end dates. One way to link these tasks is to use a hammock task.

A hammock task is a task that has its start and finish dates driven by other tasks. It does not have any work or resources assigned to it, but it can be used to show the overall duration of a group of tasks, or to link tasks that are otherwise unrelated. To create a hammock task in Microsoft Project, follow these steps:

1. Create a new task and name it as the hammock task. For example, “Contract Duration”.
2. Select the task that drives the start date of the hammock task. For example, “Contract Start”.
3. Click on Task, Information, Advanced tab.
4. In the Task Type field, select Fixed Duration.
5. In the WBS field, enter the ID of the hammock task. For example, “5”.
6. Click OK.
7. Repeat steps 2 to 6 for the task that drives the finish date of the hammock task. For example, “Contract End”.
8. Select the hammock task and click on Task, Information, Predecessors tab.
9. In the Predecessors field, enter the IDs of the tasks that drive the start and finish dates of the hammock task, separated by commas. For example, “2FS,4FS”.
10. Click OK.

You have now created a hammock task that spans from the start date of one task to the finish date of another task. You can use this hammock task to link other tasks that depend on the same external factor. For example, you can link the milestone payment task to the hammock task by entering its ID as a predecessor of the payment task.
