2 GanttProject Download version 2.6.x Has numbered tasks option The video (access from ganttproject.biz) 2

3 GanttProject Pros Easy outlining of tasks Resource management Accuracy: baseline vs. actual; various calculations Easy charting and graphics 3

4 GanttProject Cons Illusion of control Scaling No estimation features Remember: Being a Gantt Project expert does not make you an expert project manager! No more so than knowing MS-Word makes you a good writer. 4

5 The GanttProject Process 1. Move WBS into a Project outline (in Task Sheet) 2. Establish dependencies 3. Add resources (team members or roles) 4. Assign resources to tasks 5. Refine and optimize 6. Create baseline 7. Track progress (enter actuals, etc.) 5

6 Project Overview GanttProject User Interface (UI) Create a Project Add duration to the task sheet Create WBS Add task dependencies Add resources Assign resources to tasks Check Resource allocation Resolve resource allocation problems Effort-driven scheduling 6

7 GanttProject UI Views Default is Gant Chart View Task Sheet Gantt Chart 2 panes Task Sheet on left (a table) Gantt Chart on right Panels: Gantt, Resources Chart 7

8 Gantt Project UI Critical Path Tool Icons Time Scale Panels Task Outline Buttons Dependency (un)link Buttons 8

10 Setting up Resource Roles AFTER you set up your project, you can dive back in and set up roles i.e., Jobs for the team members that are associated with tasks Example: Structural Analyst, Presentation coordinator, etc. 10

11 Adding columns to the Task Sheet You can drag the columns to a different location recommend to put Outline numbers at left. 11

12 Entering WBS Outlining Sub-tasks and summary tasks Do not enter start/end dates for each Just start with Task Name and Duration for each Use Indent/Outdent buttons to define summary tasks and subtasks You can enter specific Start/End dates but don t most of the time To enter Milestones use check in Task Properties (alt+return) 12

13 Sample WBS Software design project Task Name Duration 1.0 Requirement Analysis User interviews Interview analysis GUI mock up design Validation of mockup with users Writing User Requirements User Requirements Review Meeting MS MS Milestone 13

14 Enter WBS Tasks Entering WBS tasks, tips: First, just enter all tasks and subtasks in order all are same level Next, <Ctrl-click> each subtask and indent with the right arrow icon Lastly (for this part), select each task and then <alt-enter> to access properties. 14

15 Enter tasks several ways. Right click in task panel is easiest to remember 15

16 Select the tasks and indent makes them subsets of the task not indented above them. <Tab> also indents selected task(s) Notice how Outline numbers are renumbered. 16

17 Select each subtask and add General Information 17

18 Select each subtask and add General Information Did all the dates in PAST (2012). Should do this for Present to FUTURE. 18

19 How to establish Milestone 19

20 How to establish Milestone 20

21 Add task dependencies Above task Panel: Link & Unlink buttons Good for many at once Or via Gantt chart Drag from one task to another Note: you can scroll in and scroll out to zoom on the timeline, making the tasks more accessible 21

22 Add task dependencies one at a time Drag from predecessor and Drop to successor. 22

23 Add task dependencies all at once Ctrl-click the top predecessor and all its successors (assumed below it) select dependency icon (chain link) to set dependencies. 23

24 Change Dependency Type Default dependency relationship type is Finish-to-Start Can be changed through Predecessor Panel in Task Properties For instance interview analysis and mock up design should start together Start-Start 24

25 Task Dependency Relationships Finish-to-Start (FS) B cannot start till A finishes A: Construct fence; B: Paint Fence Start-to-Start (SS) B cannot start till A starts A: Pour foundation; B: Level concrete Finish-to-Finish (FF) B cannot finish till A finishes A: Add wiring; B: Inspect electrical Start-to-Finish (SF) B cannot finish till A starts (rare) 25

26 Change Dependency Type For instance, validation of mockup can only start if both interview analysis and GUI mock-up are ready validation of mockup already set to start after GUI mock-up so set as successor to interview analysis as well. 26

27 Resources You need to first establish the roles in the Resources Properties. Then, you can define the team members under the Resources pane, and assign them those roles. 27

28 Add Resources Use Resource Panel You can add the resource s start date or Days off, too. Makes a difference when you assign a task. 28

29 WBS (already planned, more detail)!"#$%&'( )"*+', -./0 123*%4# 1*%#3 5.++%# 6$%!"! #$%&'()*%&+(%,$!-.! !"/ '()*%&+(%,'0)012$($!-.! !"3 456'789:'#;'<%$(=)!-. >-. -.!--.!"? /-. >-. >-. -.!"> B&(*()='5$%&'C%D#(&%7%)*$ /-. -.!--. >-. 29

30 Assign Resources to Tasks via the Task Pane Highlight task, Properties Resources Panel These are all that are added for the User Interviews task check your WBS to be sure 30

31 After Resources established, check for over-allocation The default colors show different types of loading (In menus, Edit Settings Resource Chart Smith is overloaded 31

32 Resource over-allocation Expand Smith s task list. Looks like Interview Analysis and GUI Mock Up together take up too much of his time 32

33 Show Critical Path Where can you delay completion without impacting the final end date? 33

34 Show Critical Path The critical path tool is not very obvious here. But we can see that the Task 1.2 duration could be extended by 2 more days without pushing the final milestone forward in time. 34

35 Back to Bob Smith s Over-allocation 2 days * 100% = 2 person days That s what we have now for him in the Interview Analysis task 1.2, and he is overloaded But, we can stretch the end date for Task 1.2, and still be on schedule. 4 days * 50% = 2 person days We can stretch Task 1.2 to 4 days duration total Then reallocate Bob to 50% over those four days. This may solve our problem 35

36 Doing the change Change Task 1.2 from 2 days duration to 4 days duration. 36

37 Doing the change Now edit the Task 1.2 Resources tab, and reduce Bob Smith s allocation from 100% to 50% for this task. 37

38 Check the Larger Resources Pane for Allocations Bob Smith is now no longer overworked. 38

39 Fully Expanded Resource Allocations 39

40 Baseline Saves all current information about your project Dates, resource assignments, durations, costs Still have not figured out details on this one 40

41 Other You keep your progress updated in each task The best way do it after each team meeting. 100% completed 75% completed 25% completed 41

42 Pert Charts Another way to view the tasks relationships 42
