GanttProject Pros
Easy outlining of tasks Resource management Accuracy: baseline vs. actual; various
calculations Easy charting and graphics
3
GanttProject Cons
Illusion of control Scaling No estimation featuresRemember: 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.

The GanttProject Process
1. Move WBS into a Project outline (in TaskSheet)
2. Establish dependencies3. Add resources (team members or roles)4. Assign resources to tasks5. Refine and optimize6. Create baseline7. Track progress (enter actuals, etc.)

Setting up Resource Roles
AFTER you set up yourproject, you can diveback in and set up“roles” i.e., Jobs for the
team members thatare associated withtasks Example:
Structural Analyst,Presentationcoordinator, etc.
10
Adding columns to the Task Sheet
11
You can drag the columns to a differentlocation—recommend to put Outlinenumbers at left.
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
Sample WBS – Software design project
1.0 Requirement Analysis 91.1 User interviews 21.2 Interview analysis 21.3 GUI mock up design 41.4 Validation of mockup with users 21.5 Writing User Requirements 21.6 User Requirements Review Meeting MS
13
DurationTask Name
“MS” Milestone
Enter WBS Tasks
Entering WBS tasks, tips:First, just enter all tasks and subtasks in
order—all are same levelNext, <Ctrl-click> each subtask and indent
with the right arrow iconLastly (for this part), select each task and then
<alt-Enter> to access properties.
14
Enter tasks—several ways.Right click in task panel iseasiest to remember
15
Select the tasks and indent—makesthem subsets of the task not indentedabove them.
16
<Tab> also indents selectedtask(s)
Notice how Outline numbersare renumbered.
Select each subtask and add GeneralInformation

How to establish Milestone

How to establish Milestone

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 thetimeline, making the tasks more accessible
21
Add task dependencies—one at a time
22
Drag frompredecessor…
…and Drop to successor.
Add task dependencies—all at once
23
Ctrl-click the toppredecessor and all itssuccessors (assumedbelow it)…
…select dependency icon (chain link)to set dependencies.
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
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
Change Dependency Type
For instance, “validation of mockup” can only start ifboth “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
Resources
You need to first establish the roles in theResources Properties. Then, you can define the team members under
the Resources pane, and assign them those roles.
27
Add Resources Use Resource Panel
28
You can add theresource’s start date orDays off, too. Makes adifference when youassign a task.
WBS (already planned, more detail)

Assign Resources to Tasks via theTask Pane Highlight task, Properties Resources Panel

These are all that are added for the “UserInterviews” task—check your WBS to be sure
After Resources established, check forover-allocation
31
The default colors show differenttypes of loading (In menus,Edit Settings Resource Chart
Smith is overloaded
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
Show Critical Path
Where can you delay completion withoutimpacting the final end date?
33
Show Critical Path
The critical path tool is not very obvious here.But we can see that the Task 1.2 durationcould be extended by 2 more days withoutpushing the final milestone forward in time.
34
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
Doing the change…
Change Task 1.2 from 2 daysduration to 4 days duration.
36
Doing the change…
Now edit the Task 1.2 Resources tab, andreduce Bob Smith’s allocation from 100% to50% for this task.
37
Check the Larger Resources Pane forAllocations Bob Smith is now no longer overworked.
38
Fully Expanded Resource Allocations

“Baseline…”
Saves all current information about yourproject Dates, resource assignments, durations, costs Still have not figured out details on this one…
