2 What is a Project? Project
An interrelated set of activities with a definite starting and ending point, which results in a unique outcome for a specific allocation of resources.

3 What is Project Management?
A systemized, phased approach to defining, organizing, planning, monitoring, and controlling projects.

6 Strategic Importance of Project Management
Bechtel Project Management: Iraq war aftermath International workforce, construction professionals, cooks, medical personnel, security Millions of tons of supplies Hard Rock Cafe Rockfest Project: 100,000 + fans planning began 9 months in advance

7 Characteristics of a Project
Project Defined A complex, nonroutine, one-time effort limited by time, budget, resources, and performance specifications designed to meet customer needs. Have a purpose, an established objective Have a life cycle, a defined life span w/ a beginning and an end Interdependencies, involvement of several departments and professionals at various levels Uniqueness, doing something that has never been done before Specific time, cost and performance requirements

8 Project , professional service
Unique Single unit Many related activities Difficult production planning and inventory control General purpose equipment High labor skills

9 Types of Development Projects
Degree of Change Type of Project

10 The project management process

11 Management of Projects
Planning - goal setting, defining the project, team organization Scheduling - relates people, money, and supplies to specific activities and activities to each other Controlling - monitors resources, costs, quality, and budgets; revises plans and shifts resources to meet time and cost demands

12 Elements Of Project Management
Project team individuals from different departments within company Matrix organization team structure with members from different functional areas depending on skills needed Project manager leader of project team

13 Project Structure Pure Project
A self-contained team works full-time on the project. Pure Project Responsibility for the project lies within one functional area of the firm. Employees from that area work on the project, usually only part-time. Functional Project A blend of pure and functional project structures – people from different functional areas work on the project, possibly only part-time. Matrix Project

14 Pure Project Structure
The project manager has full authority Team members report to one boss Shortened communication lines Team pride, motivation, and commitment are high Advantages Duplication of resources Organizational goals and policies are ignored Lack of technology transfer Team members have no functional area "home" Disadvantages

15 Functional Project Structure
A team member can work on several projects Technical expertise maintained in functional area Functional area is “home” after project completed Critical mass of specialized knowledge Advantages Aspects of the project that are not directly related to the functional area get short-changed Motivation of team members is often weak Needs of the client are secondary and are responded to slowly Disadvantages

16 Matrix Project Structure
Better communications between functional areas Project manager held responsible for success Duplication of resources is minimized Functional “home” for team members Policies of the parent organization are followed Advantages Too many bosses Depends on project manager’s negotiating skills Potential for sub-optimization Disadvantages

17 Matrix Organization Marketing Operations Engineering Finance Project 1

18 The Role of the Project Manager
Highly visible Responsible for making sure that: Project managers should be: Good coaches Good communicators Able to organize activities from a variety of disciplines All necessary activities are finished in order and on time The project comes in within budget The project meets quality goals The people assigned to the project receive motivation, direction, and information

19 Project Planning: Define the project
Statement of Work A written description of the objectives to be achieved Task A further subdivision of a project – usually shorter than several months and performed by a single group or organization Work Package A group of activities combined to be assignable to a single organizational unit

20 Defining the Project (continued)

28 Network-Planning Models
A project is made up of a sequence of activities that form a network representing a project. The path taking longest time through this network of activities is called the “critical path.” The critical path provides a wide range of scheduling information useful in managing a project. Critical path method (CPM) helps to identify the critical path(s) in the project networks.

29 Critical Path Method (CPM)
Identify each activity to be done and estimate how long it will take. Determine the required sequence and construct a network diagram. Determine the critical path. Determine the early start/finish and late start/finish schedule.

37 PERT/CPM PERT stands for Program Evaluation Review Technique.
CPM stands for Critical Path Method. PERT/CPM is used to plan the scheduling of individual activities that make up a project. PERT/CPM can be used to determine the earliest/latest start and finish times for each activity, the entire project completion time and the slack time for each activity.

DuPont & Remington-Rand (1956) deterministic task times activity-on-node network construction Project Eval. & Review Technique (PERT) US Navy, Booz, Allen & Hamilton multiple task time estimates activity-on-arrow network construction

39 Critical Path A path is a sequence of connected activities running from start to end node in network The critical path is the path with the longest duration in the network Project cannot be completed in less than the time of the critical path

42 CPM with Activity Time Estimates
When activity times vary, a single time estimate may not be reliable. Instead, estimate three values Minimum Maximum Most likely This allows calculation of a probability estimate of completion time. This is the distinguishing characteristic of the PERT method.

50 Determining the Project Schedule
Perform a Critical Path Analysis A Activity Name or Symbol Activity Duration (2) Earliest Start ES Earliest Finish EF Latest Start LS Latest Finish LF

51 Forward Pass Begin at starting event and work forward
Earliest Start Time Rule: If an activity has only a single immediate predecessor, its ES equals the EF of the predecessor If an activity has multiple immediate predecessors, its ES is the maximum of all the EF values of its predecessors ES = Max {EF of all immediate predecessors} © 2011 Pearson Education, Inc. publishing as Prentice Hall

52 Forward Pass Begin at starting event and work forward
Earliest Finish Time Rule: The earliest finish time (EF) of an activity is the sum of its earliest start time (ES) and its activity time EF = ES + Activity time © 2011 Pearson Education, Inc. publishing as Prentice Hall

53 Backward Pass Latest Finish Time Rule:
Begin with the last event and work backwards Latest Finish Time Rule: If an activity is an immediate predecessor for just a single activity, its LF equals the LS of the activity that immediately follows it If an activity is an immediate predecessor to more than one activity, its LF is the minimum of all LS values of all activities that immediately follow it LF = Min {LS of all immediate following activities} © 2011 Pearson Education, Inc. publishing as Prentice Hall

54 Backward Pass Latest Start Time Rule:
Begin with the last event and work backwards Latest Start Time Rule: The latest start time (LS) of an activity is the difference of its latest finish time (LF) and its activity time LS = LF – Activity time © 2011 Pearson Education, Inc. publishing as Prentice Hall

57 Developing the Schedule
Earliest start time (ES) - the latest earliest finish time of any immediately preceding activities Earliest finish time (EF) - the earliest start time plus its estimated duration EF = ES + t Latest finish time (LF) – the earliest of the latest start times of any of the immediately following activities. Latest start time (LS) - the latest finish time minus its estimated duration LS = LF – t Activity Slack - the maximum length of time an activity can be delayed without delaying the entire project LF-EF or LS-ES Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

65 Time-Cost Models and Project Crashing
A time-cost model extends the CPM model to consider the trade-off between time required to complete an activity and total project cost. Considers direct activity costs, indirect costs of project, and activity completion times It is often referred to as “crashing” the project to reduce overall duration.

66 Project Crashing Prepare a CPM-type network diagram.
Determine the cost per unit of time to expedite each activity. Compute the critical path. Shorten the critical path at the point where costs are lowest. Plot project, indirect, and total cost curves to find the minimum-cost schedule.

67 Analyzing Cost-Time Trade-Offs
Project Crashing Shortening (or expediting) some activities within a project to reduce overall project completion time. Project Costs Direct Costs Indirect Costs Penalty Costs Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

68 Analyzing Cost-Time Trade-Offs
Project Costs Normal time (NT) is the time necessary to complete an activity under normal conditions. Normal cost (NC) is the activity cost associated with the normal time. Crash time (CT) is the shortest possible time to complete an activity. Crash cost (CC) is the activity cost associated with the crash time. Cost to crash per period = CC – NC NT – CT Copyright ©2013 Pearson Education, Inc. publishing as Prentice Hall

69 Cost-Time Relationships

70 Earned Value Management (EVM)
A technique for measuring project progress in an objective manner Has the ability to combine measurements of scope, schedule, and cost in a project Provides a method for evaluating the relative success of a project at a point in time

71 Earned Value Management – Essential Features
A project plan that identifies the activities to be accomplished A valuation of each activity work Predefined earning or costing rules to quantify the accomplishment of work

72 Earned Value Management Charts
Budgeted costs (scheduled) and actual costs Costs of scheduled and performed work Budgeted costs (scheduled and performed work) and actual costs Budgeted cost (work performed) and actual costs
