As you schedule your project, you assign some number of resources to tasks, depending on how much help you need (and how many helpers you can manage). After you complete a draft schedule, you often end up fine-tuning some assignments—and that requires finesse, as discussed in the box on Increasing Units to Decrease Duration. For example, stakeholders may try to throw resources at a problem, only to have learning curves and chaos delay the task even more. Additional resources can increase costs, which may or may not be OK, as you learn on Paying More for Faster Delivery.
Experienced project managers know that most schedule problems have several solutions. For example, if you find under-allocated resources working on critical path tasks, you can increase their assignment units to shorten task durations. Or you can look for a person with the right skills and more available time. If you're trying to cut costs, you can look at replacing expensive resources with people with lower rates.
After you find assignments to change, the editing techniques are the same ones you learned in Chapter 9. This section identifies Project views that help you find the assignments to change, and reviews your assignment editing options.
