  25. Gantt Charts • A bar chart showing start and end dates for the activities (WBS) of a project. • Not intended to indicate how tasks must be ordered, • But simply show when a task should begin and end. • Very helpful for seeing date-time relations of activities.

  26. Gantt Charts • On the left, a work breakdown structure is located; • On the right, the time bars are located. Start: 20.02.2008 End: 28.02.2008 Duration: 7 days summary tasks leaf tasks From Microsoft Office

  27. Information on Gantt Charts • Many information can be seen on gantt charts duration of task percent of task completed From Microsoft Office

  28. Information on Gantt Charts • Precedence relations can be seen on gantt charts. Predecessor of Task A Starts at the Same time Successor of Task A Task A From Microsoft Office

  29. Information on Gantt Charts • Resource assignments can be seen on gantt charts • Resource usage can be seen on gantt charts With two full-time personnel With one Full-time personnel Many tasks in parallel With one part-time personnel With two part-time personnel From Microsoft Office

  30. Information on Gantt Charts • Critical paths can be seen on gantt charts Critical path is the longest path through the project illustrating the shortest amount of time in which a project can be completed. Tasks on critical path cannot be delayed without delaying project. Red colored tasks are on critical path. Therefore they can not be delayed. Blue colored tasks are not on critical path. Therefore they can be delayed. From Microsoft Office

  31. Techniques Supporting Project Management • Task related: • Work breakdown structures • Gantt Charts • Network Diagrams • Program Evaluation Review Technique (PERT) • Calender View • Task usage View • Resource related: • Resource Sheet • Resource Calenders • Resource Graph View • Resource Usage View

  32. Network Diagrams • A schematic display; • That illustrates various tasks in a project • As well as their sequential relationship. • A scheduling technique used for controlling resources. • Show which tasks can be done in parallel.

  33. Network Diagrams • Used to identify critical paths. • Critical path is the longest path through the project • Illustrating the shortest amount of time • In which a project can be completed. • Tasks on critical path cannot be delayed without delaying project.

  34. Network Diagrams (Sample: Summary & Leaf Tasks) From Microsoft Office

  35. Network Diagrams (Sample: Leaf Tasks) • With the information below, • You can be able to draw a network diagram.

  36. Network Diagrams (Sample: Visualisation) • Tasks are shown by either • Circles or • Rectangles. • Work flows are shown by arrows. Task 1 is the predecessor of Task 2 1 2 Task 2 follows Task 1 Task 1 Task 2
