What is Project Management?
Project : A group of milestones or phases, activities or tasks that support an effort to accomplish something
Management : is the process of Planning,
Organizing, Controlling and Measuring
4Philadelphia University
Project...A collection of linked activities, carried out in
an organized manner, with a clearly defined START POINT and END POINT to achieve some specific results desired to satisfy the needs of the organization at the current time
5Philadelphia University
What Is a Project?A project is “a temporary endeavor
undertaken to create a unique product, service, or result.”*
Operations is work done to sustain the business.
A project ends when its objectives have been reached, or the project has been terminated.
Projects can be large or small and take a short or long time to complete.
6Philadelphia University
Attributes of a ProjectHas a well-defined objectiveComposed of a series of interdependent tasks Utilizes various resourcesHas a specific time frameMay be a unique or one-time endeavorHas a customerInvolves a degree of uncertainty
7Philadelphia University
Project ManagementA dynamic process that utilizes the
appropriate resources of the organization in a controlled and structured manner, to achieve some clearly defined objectives identified as needs.
It is always conducted within a defined set of constraints
8Philadelphia University
Why Need Project Management?• Complex project needs coordination of:
Multiple peopleMultiple resources (labs, equipment, etc.)Multiple tasks – some must precede othersMultiple decision points – approvalsPhased expenditure of fundsMatching of people/resources to tasks
9Philadelphia University
Who uses Project Management? Nearly Everyone to some degree
People plan their Days, their Weeks, their Vacations and their Budgets and keep a simple project management form known as ‘’To Do’’ list
Any Process or Means used to track tasks or efforts towards accomplishing a goal could be considered Project Management
10Philadelphia University
The Project Management ProcessThe project management process means planning
the work and then working the plan.
Clearly define the project objective.
Divide and subdivide the project.
Define the specific activities that need to be
performed.
Graphically schedule the activities in a project.Make a time estimate.Make a cost estimate.
Calculate a project schedule and budget.11Philadelphia University
Benefits of Project ManagementLess overall project costEffective use of resourcesMore timely project completionHigher quality of the final product
12Philadelphia University
Controlling ProjectsEstablish a baseline plan.Monitor progress.Measure actual progress and compare it to
planned progress.Take corrective action if the project is behind
schedule, overrunning the budget, or not meeting technical specifications.
13Philadelphia University
Suggested Steps in Project Management• Generate a formal definition of the project, with
goals, constraints, assumptions• Identify project start/end dates, any mandatory
milestones, including reports, signoffs, deliverables, etc.
• List constraints – money, equipment availability, holidays, etc.
• Identify tasks to be accomplished – high level (i.e., by categories), then details within each, using brainstorming method – green light
14Philadelphia University
Suggested Steps, cont.• Refine detailed task list, dropping/ combining,
adding things omittedThen, for each task in list:• Estimate time (person hours, calendar period)• Identify dependencies among tasks• Identify resources (people, money, parts, etc.)
15Philadelphia University
Suggested Steps, cont.Organize task groups roughly by starting dateList dependencies that should or MUST holdUse MS Project to make a GANTT chart• First capture tasks and task groups, milestones• Identify critical path, see if it can be shortened • Assign person-hours and specific team member(s)
to each task – identify “task leads”
16Philadelphia University
Suggested Steps, cont.As project progresses:• Monitor, record progress on all tasks, at least
weekly – use “Tracking Gantt Chart”• Pay particular attention to those on critical
path• Revise plan as needed to take into account
changes, adapt to meet milestones

Project Close-out PhaseDocument the lessons learned during the
projectAfter-implementation reviewProvide performance feedbackClose-out contractsComplete administrative close-outDeliver project completion report
23Philadelphia University
project scope definition
Project scope is the part of project planning that involves determining and documenting a list of specific project goals, deliverables, tasks and deadlines.
25Philadelphia University
Project ConstraintThe time constraint refers to the amount of time
available to complete a project. The cost constraint refers to the budgeted amount available for the project. The scope constraint refers to what must be done to produce the project's end result. These three constraints are often competing constraints: increased scope typically means increased time and increased cost, a tight time constraint could mean increased costs and reduced scope, and a tight budget could mean increased time and reduced scope.
26Philadelphia University
Time
For analytical purposes, the time required to produce a deliverable is estimated using several techniques. One method is to identify tasks needed to produce the deliverables documented in a work breakdown structure or WBS. The work effort for each task is estimated and those estimates are rolled up into the final deliverable estimate.
27Philadelphia University
Project Time Management processes include: Define Activities Sequence Activities Estimate Activity Resources Estimate Activity Durations Develop Schedule Control Schedule
28Philadelphia University
Cost
To develop an approximation of a project cost depends on several variables including: resources, work packages such as labor rates and mitigating or controlling influencing factors that create cost variances.
29Philadelphia University
Cost Process Areas
Cost Estimating is an approximation of the cost of all resources needed to complete activities.
Cost budgeting aggregating the estimated costs of resources, work packages and activities to establish a cost baseline.
Cost Control – factors that create cost fluctuation and variance can be influenced and controlled using various cost management tools.
30Philadelphia University
ScopeRequirements specified to achieve the end
result. The overall definition of what the project is supposed to accomplish, and a specific description of what the end result should be or accomplish. A major component of scope is the quality of the final product. The amount of time put into individual tasks determines the overall quality of the project. Some tasks may require a given amount of time to complete adequately, but given more time could be completed exceptionally. Over the course of a large project, quality can have a significant impact on time and cost (or vice versa).
31Philadelphia University
Work Breakdown Structure (WBS)
Breaks large project into manageable unitsTotal projectSubprojectsMilestones (completion of an important set of
work packages)Major activities (summary tasks)Work packages (tasks, activities, work
elements)
33Philadelphia University
Work Breakdown Structure (WBS)Helps to:
Identify all work needing to be done Logically organize work so that is can be
scheduledAssign work to team membersIdentify resources neededCommunicate what has to be doneOrganize work using milestones
34Philadelphia University
SchedulingScheduling - Determination of timing and
assembly of project activities to give overall completion time
36Philadelphia University
Basis for Project ScheduleProject objectivesProject scopeProject milestonesProject estimate (budget)Resource availability
37Philadelphia University
Purposes of Project SchedulingPurposes of Project Scheduling1. Shows the relationship of each activity to others
and to the whole project2. Identifies the precedence relationships among
activities3. Encourages the setting of realistic time and cost
estimates for each activity4. Helps make better use of people, money, and
material resources by identifying critical bottlenecks in the project
38Philadelphia University
PROJECT SCHEDULING MODELS Gantt charting and the Program Evaluation
and Review Technique (PERT). Both are schematic models, but the PERT
also is a mathematical model.
39Philadelphia University
GANTT CHARTS A Gantt chart is a tool to monitor progress. Showing
both planned and actual outcomes for each phase, a Gantt chart allows you to isolate and solve scheduling problems in a methodical manner. While the project as a whole might be overwhelming, a Gantt chart helps in managing a large project by breaking the project into a series of smaller phases. As each phase is completed, you can see if the final deadline is likely to be met. If you are behind schedule, you can attempt to get back on track by absorbing the delay in one phase by making it up in another phase
A Gantt chart may be constructed using several techniques involving different combinations of lines and symbols. The actual and planned beginning and ending points for each phase are plotted along a time line. The first phase is plotted at the top and the last phase is plotted at the bottom. Gantt charts may be constructed by hand or through computer software packages.
40Philadelphia University
Steps to create Gantt chart What the various activities areWhen each activity begins and endsHow long each activity is scheduled to lastWhere activities overlap with other activities,
and by how muchThe start and end date of the whole project
41Philadelphia University
PERT and CPMPERT and CPM Network techniques Developed in 1950’s
CPM by DuPont for chemical plants (1957) PERT by Booz, Allen & Hamilton with the
U.S. Navy, for Polaris missile (1958)
Consider precedence relationships and interdependencies
Each uses a different estimate of activity times
43Philadelphia University
Six Steps PERT & CPMSix Steps PERT & CPM1. Define the project and prepare the work
breakdown structure2. Develop relationships among the activities -
decide which activities must precede and which must follow others
3. Draw the network connecting all of the activities
44Philadelphia University
Six Steps PERT & CPMSix Steps PERT & CPM4. Assign time and/or cost estimates to each
activity5. Compute the longest time path through the
network – this is called the critical path6. Use the network to help plan, schedule,
monitor, and control the project

PERT Diagram ExamplePERT Diagram ExampleFor example, the optimistic time for
completing activity H is 2 days, the most likely time is 4 days, but the pessimistic time is 12 days. The next step is to calculate an expected time, which is determined as follows:
te (expected time) = (a + 4m + b) / 6 For example, for activity H, the expected
time is (2 + 4(4) + 12) / 6 = 30 / 6 = 5 days
50Philadelphia University
PERT Diagram ExamplePERT Diagram ExampleAs a measure of variation (uncertainty) about
the expected time, the standard deviation is calculated as follows:
σ = (b - a) / 6 For example, the standard deviation of
completion time for activity H is: σ = (12 - 2) / 6 = 10 / 6 = 1.67 days

Critical PathCritical PathAn easy way to find the critical path involves
the following two steps: 1. Identify all possible paths of a project and
calculate their completion times. 2. Pick the one with the longest amount of
completion time, which is the critical path.
53Philadelphia University
Critical PathCritical PathIn the example, we have: Path Completion time A-C-G 13 days (3 + 2 + 8) B-D-G 20 days (2 + 10 + 8) B-E-F-G 17 days (2 + 2 + 5 + 8) B-E-H 9 days (2 + 2 + 5) The critical path is B-D-G, which means it
takes 20 days to complete the project.
