A Critical Path Analysis diagram uses a linear timeline to identify dependent tasks and is particularly used on large, complex projects which may have hundreds of dependent activities. These diagrams highlight dependent tasks that overlap and, therefore, require adjustments to the schedule.
A Gantt Chart is an excellent project management tool for the scheduling, budgeting and reporting of a project. The easiest, but perhaps not the most useful, tool for creating Gantt Charts is MSProject. Each task is listed on the left-hand side of the chart with a timeline shown on the right. Milestones can be easily marked and the schedule and costs can be easily updated where necessary.
