USING MS PROJECT 2010
M. J. Liberatore VSB 3008
• • • Project management software programs such as Microsoft Project 2010 can be used for developing the project schedule and budget, and tracking actual vs. planned progress We demonstrate the use of MS Project 2010 for a sample project • Complete model found in construction.mpp on class web page Begin by launching MS Project 2010
MS Project 2010 Setup
• Select
File, Options
, click on
“
Schedule” tab • For Calendar options for this project: “Select “All New Projects” • For Scheduling options for this project: select “All New Projects” • For New Tasks Created: select “Auto Scheduled” • For Duration is entered in: select “weeks” • For default task type: select “fixed duration” • make sure New tasks are effort driven is
NOT
checked • Click
OK
when finished
MS Project 2010 Setup
Creating a Project
• Click on
Project, Project Information
, select 10/3/11 as the Start date, click
OK
• Click on
Save as
, type in project name such as
Demo
, click
OK
• Your project is saved as Demo.mpp

Entering Task Information
• Default view,
Entry
table on left,
Gantt Chart
on right • You can delete the two left-most columns, “i” and “task mode” by highlighting these columns and pressing the “delete” key (not needed by us) • Task numbers now in left-most column • Enter task name and duration in their field • • The default is weeks or “w” “d” for days and “h” for hours can be used • Enter predecessor task number(s) in the “Predecessors” field • MS Project
automatically
gives start and finish dates based on critical path analysis
Entering Task Information
Task Information
Double-clicking on a task name opens the Task Information” screen
Project Charts
• The
Gantt Chart
view shows task linkages • Since START and FINISH are dummy activities with 0 duration, they are
milestones in MS Project
(black diamonds) Right-click on dates in the chart and then “zoom” as desired • Change view to

Diagram” (zoom as desired) by clicking on “View” in the menu and then select “Network

Critical Path Analysis
• MS Project 2010 automatically computes the critical path and the earliest and latest start and finish times and slack •
Project, Project Information, Statistics
shows the critical path is 26 weeks in our project
Project Critical Path Length
Critical Path Analysis
• Use the “Detail Gantt” to best display the critical path • Select “View”, “Other Views”, “More Views”, “Detail Gantt” then “Apply” • Use the “Schedule Table” to display all of the early and late start and finish information, along with total and free slack • Again from “View”, select “Table”, and then “Schedule”
Schedule Table & Detail Gantt
Critical Path Analysis
• • • Critical path tasks can be identified as those have zero
total slack (TS)
or
float
• • TS = LF – EF = LS – ES
The TS of only 1 task can be used if we want to be certain about not delaying the project
Free slack (FS) of a task is the difference between the smallest of the ES’s of the task’s immediate successors and the task’s EF.
• Using FS does not affect the start times of a task’s successors • • FS <= TS
FS of multiple tasks can be used without delaying the project FS is shown on the Detail Gantt
Critical Path Analysis
• Notice that tasks 12 and 13 both have 7 weeks of total slack • However, if task 12 uses this slack, it is not available to task 13, so its slack is not free • Tasks 12 and 13 are linked, so delaying the start of 12 delays the start of 13 by the same amount
Summary Tasks
•
Summary tasks
can be used to better organize a project (see constructionS.mpp) • We add three summary tasks: Structure, Interior, and Exterior • Structure includes current tasks 2 – 4, Interior includes 6 – 11, Exterior includes 5, 12, 13 • Example: highlight “Excavate and Pour Footers,” click on “Tasks”, click on” Summary,” enter “Structure” • Indent first three tasks under “Structure” by highlighting them and selecting “indent” (thick green arrow going to the right)
