1-Add Phases to Tasks
2-Add Tasks to Phases
Projects can be planned from top to down or from down to top. In the top- down approach, the major phases are entered first and sub- tasks inside the phases are then entered. In the other way, the detailed tasks are first listed out and then can be grouped into phases or summary tasks. A number of outline view options are available which allow viewing of tasks and phases at different levels.
