TheTripleConstraintEvery project is constrained in different ways by its
• Scopegoals:Whatistheprojecttryingtoaccomplish?
• Timegoals:Howlongshouldittaketocomplete?
• Costgoals:Whatshoulditcost?It is the project manager’s duty to balance these three often competing goals

WhatisProjectManagement?
• Project management is “the application of knowledge, skills, tools, and techniques to project activities in order to meet project requirements” (PMI*, Project Management Body of Knowledge (PMBOK® Guide), 2000, p. 6)
*TheProjectManagementInstitute(PMI)isaninternationalprofessionalsociety.Theirwebsiteiswww.pmi.org.
• The art of organising, leading, reporting and completing a project through people

ProjectStakeholders• Stakeholders are the people involved in or affected by project
activities
• “A person or group of people who have a vested interest in the
success of an organization and the environment in which the
organization operates”
Stakeholders include• theprojectsponsorandprojectteam
• supportstaff
• customers
• users
• suppliers
• opponentstotheproject

ProjectManagementToolsandTechniques
• Project management tools and techniques assist project managers and their teams in various aspects of project management
Some specific ones include• ProjectCharter,scopestatement,andWBS(workbreakdownstructure)

• Ganttcharts,networkdiagrams,criticalpathanalysis,criticalchain

HistoryofProjectManagement
• Some people argue that building the Egyptian
pyramids was a project, as was building the Great
Wall of China
• Most people consider the Manhattan Project to be
the first project to use “modern” project
management
• This three-year, $2 billion (in 1946 dollars) project
had a separate project manager and a technical
manager
KeyPointsinProjectSet-upandDefinition
n Create Project Management Plan (PMP)
n Be clear of scope and objectives
n Establish clear statement of what is to be done (WBS)
n Establish Risks to be Managed

n Defines the following:-ð Project Objectives, Scope, Deliverables
ð Stakeholders (Internal & External)
ð Work to be done (WBS)
ð Project Organisation and Resources (OBS)
ð Project Costings (CBS)
ð Project Schedule
ð Procurement/Contract Strategy
ð Risk Management
ð Quality management
ð Change Management

Is he or she at sufficiently high level in theorganization to provide the project with support and a good chance ofsuccess?

• List project tasks as you think of them on the task
list. (you’re constrained by the scoping agreement
and the requirements statements)
• Include all tasks, both big and small, necessary to
complete the project.
• Then record the effort needed for each task using
your best time estimate.
• Complete the task list by denoting all milestone
events with a capital M.
CreatingtheWorkBreakdown StructureüüWork Breakdown Structure (WBS)
• An hierarchical outline (map) that identifies the products and work elements involved in a project
• Defines the relationship of the final deliverable (the project) to its subdeliverables, and in turn, their relationships to workpackages
• Best suited for design and build projects that have tangible outcomes rather than process--oriented projects
• structured grouping of tasks into categories of broad tasks, subtasks, subsubtasks, etc.
• is a tree diagram of the task list and is displayed either in an outline format or an organizational-chart type format.
