Control Schedule tools and techniques:
Performance reviews: There are two important calculations called schedule variance (SV) and schedule performance index (SPI) that give you valuable information about how your project is doing.
Project management software: This is software like Microsoft Project that helps you organize and analyze all of the information you need to evaluate the schedule of any project.
Leads and lags, modeling techniques, schedule compression, scheduling tool: Most of the tools from the last process apply to this one too. As you find variances in the schedule, you need to figure out the impact of those issues and change your schedule to account for the new information.
Resource optimization techniques: As things change in your project, you need to make sure that resources are covering all of the activities in your plan. That means you need to distribute resources so that the work that needs to get done always has a resource available to do it.
Schedule comparison-à Fast tracking and Crashing are the tool for schedule comparison.
When there is overlapping of activities means fast tracking and there is always increase in cost and adding resource when we talk about crashing.
You cannot use crashing when project budget is fixed because crashing always increase the budget of the project. Crashing also include new resource and which will cost more.
Another schedule compression technique is called fast-tracking. Sometimes you’ve got two activities planned to occur in sequence, but you can actually do them at the same time. On a software project, you might do both your UAT testing and your functional testing at the same time, for example.
