This resource focuses on fundamental aspects of project management including definitions, structures, and control charts. Key elements such as the work breakdown structure, critical path scheduling, and the project life cycle are explored. It highlights the importance of defining clear project objectives and provides examples across various industries. Key issues in setting objectives are discussed along with methods for managing a project efficiently, ensuring client satisfaction, and navigating the complexities of resource allocation throughout a project's duration.

Project Management Class 2: 1/19/11
3-2 OBJECTIVES • Definition of Project Management • Work Breakdown Structure • Project Control Charts • Structuring Projects • Critical Path Scheduling
3-3 Project Examples • Building: a ship, a satellite, an oil rig, and a nuclear plant. • Developing: computer programs, an advertising campaign, a new product, a new process, and training materials. • Implementing: new technologies and work procedures.
3-4 Project Management Defined • A Project is a series of related jobs usually directed toward some major output and requiring a significant period of time to perform • Project Management are the management activities of planning, directing, and controlling resources (people, equipment, material) to meet the technical, cost, and time constraints of a project
3-5 Objectives of a Project
3-6 Objectives of a Project The 4th dimension: client satisfaction
3-7 Project Life Cycle Project Life Cycle: changing patterns of resource usage and level of activity over the course of the project
3-8 Project Life Cycle • Stages of a Conventional Project: • Slow beginning • Buildup of size • Peak • Begin a decline • Termination
3-9 Project Life Cycle
3-10 Project Life Cycle Time distribution of project effort is characterized by slow-rapid-slow
3-11 Project Life Cycle • Try to avoid the “90-90 rule of project management”: The first 90% of the project takes 90% of the time, the last 10% takes the other 90%.
3-12 Project Life Cycle What does this rule really mean?
3-13 Project Life Cycle • During the life cycle cycle, project management is accomplished through the use of processes such as: • Initiating, planning, executing, controlling, and closing • Many of these processes are iterative in nature because the project is being progressively elaborated
3-14 Defining Project Objectives Why Set Project Objectives • To provide direction for project activities • To enable measuring results against prior exceptions • Resource usage (manpower, materials, etc.) • Schedule integrity • Quality of work • To determine specific goals which will provide maximum effectiveness of project activities
3-15 Defining Project Objectives Requirements for Project Objectives • Achievable (time, resources, staff) • Understandable (vs. complex) • Specific (vs. general, vague statements) • Tangible (“deliverables”) • Measurable (resources, schedule, quality) • Consistent (with strategy, programs, policies, procedures) • Assignable (department or individual)
3-16 Defining Project Objectives Some Problems in Setting Objectives • Stating activities rather than deliverables • Exceeding the scope of the defined project • Failing to be specific • Omitting important deliverables • Inconsistency with stated policies
3-17 Defining Project Objectives Example: D.U. Singer Project Title: Permanent Antiseptic Production Start-Up • Objectives: • Develop a comprehensive plan for the production of a new, permanent antiseptic • Complete development and testing of a manufacturing process that: • Meets all current FDA, EPA, and OSHA regulations as well as internal specifications • produces 95% yield of product (full packaged) at a level of 80% of full production goal of 10 million liters per year

3-25 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
3-26 Prerequisites for Critical Path Methodology A project must have: well-defined jobs or tasks whose completion marks the end of the project; independent jobs or tasks; and tasks that follow a given sequence.
3-27 Steps in the CPMMethod • Activity Identification • Activity Sequencing and Network Construction • Determine the critical path • From the critical path all of the project and activity timing information can be obtained

3-30 Find the Critical Path • Activities on the critical path cannot be delayed without delaying the completion of the project • There are two paths: A – B – C – D – F – G: 12 weeks A – B – C – E – F – G: 15 weeks • Activity D can be delayed by up to 3 weeks without delaying the project • The longest path is critical – why?

3-37 Critical Path for Great Valley Hospital Project • Four paths in the network: Path 1: Start – A – C – F – H: 9 weeks Path 2: Start – A – C – E – G – H: 15 weeks Path 3: Start – A – D – G – H: 13 weeks Path 4: Start – B – D – G – H: 14 weeks • Path 2 is critical See GreatValley.mpp
3-38 Critical Path for Great Valley Hospital Project • A, C, E, G, and H are on the critical path and so they have 0 slack • B is on path 4, so its slack is 15 – 14 = 1 • D is on paths 3 and 4, so its slack is 15 – Max (13,14) = 1 • F is on path 1, so its slack is 15 – 9 = 6 • An activity can be delayed by its slack and not delay the project completion

3-42 Time-Cost Models • In construction, incentives for completing project early • In new product development, revenue stream starts earlier if project is launched earlier • Time-Cost Models: • To accelerate the completion of a project, expedite or “crash” the critical path project activity that has the cheapest cost per unit time to shorten its duration
3-43 Steps in Time-Cost Analysis • Using normal activity times, find the critical path • Compute the crash cost per time period: Crash cost/period = (Crash cost - Normal cost)/ (Normal time - Crash time) • If there is only one critical path, select the activity on the critical path that (a) can still be crashed, and (b) has the smallest crash cost per period • If there are multiple critical paths, select the cheapest crash cost combination of critical path activities that can still be crashed that will reduce ALL critical paths by one period • Update all activity times and repeat process if further reduction in critical path time is desired

3-45 Example 3. Great Valley Hospital Project Crashing Analysis • Select the activity with smallest crash cost per week that is on the critical path – activity A at a cost of $750 • Start – B – D – G – H is also critical (14 wks) • Crash G by 1 week at a cost of $1,500 to reduce the project by an additional week (vs. crashing C and D at a combined cost of $2,000)
