Lean Project Management
Project Management Overview
2
What is a Project? A temporary endeavor to create a unique product, service, or result. Characteristics: Specific goal or deadline Complex, interrelated tasks, special skills Critical to organization Cross-functional
3
Examples of Projects Construction Software development
New product development Research New business
4
Management of Projects
Initiating - goal setting, defining the project, project charter team organization Planning – scope statement, estimates, approval Executing – project team, accomplish tasks of the project, manage expectations, test Monitoring and Controlling - monitor resources, costs, quality, and budgets; revise plans and shift resources to meet time and cost demands Closing – contract closure, project close PMBOK
5
Project Management Techniques
Gantt chart Critical Path Method (CPM) Program Evaluation and Review Technique (PERT) Critical Chain Project Management (CCPM) Lean Project Management
6
Gantt Charts Horizontal bar chart showing time and task
Developed in 1910s by Henri Gantt Can consider precedence relationships Can use multiple or single task time estimates
7
PERT and CPM Network techniques Developed in 1950s
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
8
Six Steps PERT & CPM Define the project and prepare the work breakdown structure Develop relationships among the activities - decide which activities must precede and which must follow others Draw the network connecting all of the activities
9
Six Steps PERT & CPM Assign time and/or cost estimates to each activity Compute the longest time path through the network – this is called the critical path Use the network to help plan, schedule, monitor, and control the project

Questions PERT & CPM Can Answer
When will the entire project be completed? What are the critical activities or tasks in the project? Which are the noncritical activities? What is the probability the project will be completed by a specific date?
12
Questions PERT & CPM Can Answer
Is the project on schedule, behind schedule, or ahead of schedule? Is the money spent equal to, less than, or greater than the budget? Are there enough resources available to finish the project on time? If the project must be finished in a shorter time, what is the way to accomplish this at least cost?

Cost–Time Trade-Offs and Project Crashing
It is not uncommon to face the following situations: The project is behind schedule The completion time has been moved forward Shortening the duration of the project is called project crashing
26
Problems with Traditional PM
Late Slow Expensive
27
Critical Chain Project Management
Moving buffers out of individual tasks Two questions: What task do I work on next? When do I take actions to accelerate the project? Emphasis on speed
