In this tutorial, we learn how to use task types in MS Project 2007. First, open up the form view of all the different tasks you have. Now, look at the unit task type and see if it's effort driven or fixed units. Now, change what you want the task type to be and then click on the next button. Assign a second resource if you need to, then change the duration if you need to as well. Continue to change the task types depending on what durations you have then make sure to save this. Double check that your schedule is right, then change as you need.
