To shrink your project schedule, look at critical tasks first. If you want, you can display critical tasks in order of longest to shortest duration; you can then see which critical tasks have the biggest effect on the project end date. If you can shorten the duration of the longest tasks, you might be able to shorten the overall length of your project. You can shorten task durations by assigning more resources, reducing task scope, or breaking large tasks into smaller tasks and starting some sooner. You can also make tasks end sooner by changing their links.
