4. About Gantt Charts A graphical representation of the duration of tasks against the progression of time A useful planning tool for planning and scheduling projects Helpful when monitoring a project’s progress Allows you to assess how long a project should take Allows you to see immediately what should have been achieved at a point in time

5. About Gantt Charts Allows you to see how remedial action may bring the project back on course Lays out the order in which tasks need to be carried out Helps manage the dependencies between tasks

6. Gantt Chart Put onto one page Summary view of the marking period Planned and current dates Status of each phase Forecasted finish dates Major milestones marked by symbols with abbreviated text Major completion dates Meaning of symbols defined in legend

7. Symbols Use indicator symbols to show which project items need attention Tips on using indicator symbols Use distinct shapes and colors to clearly separate one indicator from another Rely on the indicator’s shape, not color, when printing to black and white Clearly define the indicators in a legend Use logical symbols, such as check-marks for completed activities Display “pie-fills” to show percent complete

8. Symbols Use ‘stoplights’ as a quick visual of tasks that are ahead of schedule, on schedule, or behind schedule Use check-marks to indicate a completed task 

10. Cell color highlights allow easy viewing and show task responsibility

11. Use consistent symbology “What symbol do I use for a critical milestone?” Use simple intuitive symbol choices Be consistent in applying the symbology Clearly define the meaning of each symbol in a legend

12. Examples of symbology Green for starting activities Red for finishing activities Yellow for “on-hold” Check mark for completed items Up arrow to start Down arrow for completion Slash mark for changed date Diamond for critical milestones Once your symbology is established, save the format to be re-used
