PROJECT MANAGEMENT (N MBA 034) What is a Project? • Project Defined –A complex, Nonroutine, One-time effort – limited by time, budget, resources ( Triple Constraint) –Performance specifications designed to meet customer needs. • Major Characteristics of a Project –Has an established objective. –Has a defined life span with a beginning and an end. –Requires across-the-organizational participation. –Involves doing something never been done before. –Has specific time, cost, and performance requirements. Project Characteristics ► ► ► ► ► Single unit Many related activities Difficult production planning and inventory control General purpose equipment High labor skills Examples of Projects ► Building Construction ► Research Project Programs versus Projects • Program Defined –A series of coordinated, related, multiple projects that continue over an extended time and are intended to achieve a goal. –A higher level group of projects targeted at a common goal. –Example: • Project: completion of a required course in project management. • Program: completion of all courses required for a business major. Comparison of Routine Work with Projects Routine, Repetitive Work Projects Taking class notes Writing a term paper Daily entering sales receipts into the accounting ledger Setting up a sales kiosk for a professional accounting meeting Responding to a supply-chain request Developing a supply-chain information system Practicing scales on the piano Writing a new piano piece Routine manufacture of an Apple iPod Designing an iPod that is approximately 2 X 4 inches, interfaces with PC, and stores 10,000 songs Attaching tags on a manufactured product Wire-tag projects for GE and Wal-Mart Project Life Cycle Project Management Activities Planning ► ► Objectives ► Resources ► Scheduling ► Work breakdown structure ► ► ► Organization Start & end times ► ► ► Controlling Monitor, compare, revise, action Project activities Network Project Organization Often temporary structure ► Uses specialists from entire company ► Headed by project manager ► ► ► ► Coordinates activities Monitors schedule and costs Permanent structure called ‘MATRIX ORGANIZATION’ Project Organization Works Best When 1. Work can be defined with a specific goal and deadline 2. The job is unique or somewhat unfamiliar to the existing organization 3. The work contains complex interrelated tasks requiring specialized skills 4. The project is temporary but critical to the organization 5. The project cuts across organizational lines A Sample Project Organization President Human Resources Marketing Project No. 1 Project No. 2 Finance Design Quality Mgt Production Project Manager Mechanical Engineer Test Engineer Technician Project Manager Electrical Engineer Computer Engineer Technician Matrix Organization Marketing Project 1 Project 2 Project 3 Project 4 Operations Engineering Finance The Importance of Project Management • Factors leading to the increased use of project management: –Compression of the product life cycle –Knowledge explosion –Triple bottom line (planet, people, profit) –Corporate downsizing –Increased customer focus –Small projects represent big problems Benefits of an Integrative Approach to Project Management • Integration (or centralization) of project management provides senior management with: –An overview of all project management activities –A big picture of how organizational resources are used –A risk assessment of their portfolio of projects –A rough metric of the firm’s improvement in managing projects relative to others in the industry –Linkages of senior management with actual project execution management Integrated Project Management Systems • Problems resulting from the use of piecemeal project management systems: –Do not tie together the overall strategies of the firm. –Fail to prioritize selection of projects by their importance of their contribution to the firm. –Are not integrated throughout the project life cycle. –Do not match project planning and controls with organizational culture to make appropriate adjustments in support of project endeavors.

Especially useful when scheduling and controlling large projects 2. Straightforward concept and not mathematically complex 3. Graphical networks help highlight relationships among project activities 4. Critical path and slack time analyses help pinpoint activities that need to be closely watched Advantages of PERT/CPM 5. Project documentation and graphics point out who is responsible for various activities 6. Applicable to a wide variety of projects 7. Useful in monitoring not only schedules but costs as well Limitations of PERT/CPM 1. Project activities have to be clearly defined, independent, and stable in their relationships 2. Precedence relationships must be specified and networked together 3. Time estimates tend to be subjective and are subject to fudging by managers 4. There is an inherent danger of too much emphasis being placed on the longest, or critical, path
