Changing the Dependency in the Predecessors menu to “Finish-to-start”
Open Task Settings by double clicking on the task that is being worked on. Select Predecessors, which is the third tab under Task Properties). From there, click on the task that you will want to finish before starting the task you are working on.
Remember to think of this as a sentence: (task that is checked off) needs to finish to start (task that is highlighted)
Use this same logic when selecting other types of dependencies.
Changing your Constraint in the Advanced settings:
ASAP- meaning as soon as possible
ALAP- meaning as late as possible
While under Task Settings of the highlighted task, click on the gear icon next to the name of the task to open up the advanced settings. It is here where you can view constraints used on the task in question. Then change the constraint to one of the listed options such as “As late as Possible”. Then hit the “Save Task” button.
