Essential aspects of tasks in a project plan include their duration and order of occurrence.
The Project Guide can help you develop a good initial task list.
Task links, or relationships, cause the start or end of one task to affect the start or end of another task. A common task relationship is a finish-to-start relationship, where the completion of one task controls the start of another task.
In Project, phases of a schedule are represented as summary tasks.
The Project Information dialog box (Project menu) is an excellent way to see the key values of a project plan, such as its scheduled finish date and duration.
