planning, estimating and risk - Kickoff meetings are important
- Work Breakdown Structures
- Do not introduce benefits that are not stated in
requirements - Needs of all stakeholders should be taken into
account during all projects - Team Members must be involved in project planning
- Project Mangers must be pro-active
4Chapter 1 Introduction
- Project temporary endeavor undertaken to create
a unique product or service - Has a definite beginning and end and interrelated
activities - Programs adopt new set of objectives and continue
to work projects cease when declared objectives
have been attained
5Chapter 1 Introduction
- Projects are unique characteristics are
progressively elaborated - Progressively proceeding in steps
- Elaborated worked with care and detail
- Scope of project should remain constant even as
characteristics are progressively elaborated
6Chapter 1 - Introduction
- Project Management the application of knowledge,
skills, tools and techniques to project
activities in order to meet or exceed stakeholder
needs and expectations from a defined project
balancing the following - Scope, time, cost, and quality
- Stakeholders expectations
- Requirements (needs) vs. unidentified
requirements (expectations)
7Chapter 1 - Introduction
- Programs are groups of projects managed in a
coordinated way to obtain benefits not available
from managing the projects individually - Most programs have elements of ongoing operations
- Series of repetitive or cyclical undertakings
- Projects are often divided into subprojects for
more manageability - Often contracted out to external organizations
8Chapter 2 Project Management Context
- Project Phases are marked by the completion of a
deliverable - Tangible, verifiable work product
- Review of deliverables and approval/denial are
phase exits, stage gates, or kill points - Phases are collected into the Project Life Cycle
- Set of defined work procedures to establish
management control
9Chapter 2 Project Management Context

low at beginning, higher towards the end as
project continues - Stakeholder influence is high at the beginning
and progressively lowers as project continues
10Chapter 2 Project Management Context

before to activity can begin most commonly
used - Finish to Finish from activity must finish
before the next may finish - Start to Start from activity must start
before next to activity can start - Start to Finish task must start before next
activity can finish - Use caution with last 3 techniques - logical
relationships often not consistently implemented
with project management software

- PERT (Program Review and Estimating Technique)
- 3 Time estimates per activity
- Optimistic
- Pessimistic
- Most Likely
- Emphasis on meeting schedule, flexibility with
costs - Drawn on AOA diagrams
- Can have dummy tasks
100Chapter 6 Project Time Management
- Schedule Development Tools Techniques
- Monte Carlo Analysis
- Uses a computer with PERT values and network
diagram - Tells
- Probability of completing a project on any
specific day - Probability of completing a project for any
specific amount of cost - Probability of any task actually being on the
critical path - Overall Project Risk
- Suggests that Monte Carlo simulation will create
a project duration that is closer to reality than
CPM or PERT
101Chapter 6 Project Time Management
- Schedule Development Tools Techniques
(continued) - Duration Compression look to shorten project
schedule without affecting scope - Crashing cost and schedule trade-offs to
determine greatest amount of compression for
least incremental cost often results in higher
costs - Fast Tracking performing activities in parallel
that normally would be sequenced often results
in re-work and usually increases risk - Simulation
102Chapter 6 Project Time Management
- Schedule Development Tools Techniques
(continued) - Resource Leveling Heuristics leveling resources
that apply to critical path activities a.k.a.
resource constrained scheduling when
limitation on quantity of available resources
sometimes called Resource Based Method often
increases project duration - Project Management Software
103Chapter 6 Project Time Management
- Schedule Development Tools Techniques
(continued) - Project Mangers role
- Provide the team with the necessary information
to properly estimate the task - Complete a sanity check of the estimate
- Formulate a reserve
- Project Team should be involved determine task
estimates - Historical Records
- Guesses
- Actual Costs
- Benchmarks
- CPM and PERT
104Chapter 6 Project Time Management
- Schedule Development Tools Techniques
- Critical Path Method longest path through a
network diagram and determines the earliest
completion of the project - Proves how long the project will take
- Indicates tasks that need most monitoring
- Almost always have no slack
105Chapter 6 Project Time Management
- Schedule Development Outputs
- Project Schedule includes planned start and
finish dates for each activity remains
preliminary until resources assignments are
approved. Usually in following formats - Project Network Diagrams (with date information
added) show logical and critical path
activities - Bar or Gantt charts activity start and end
dates, expected durations - Milestone Charts identifies key deliverables
and interfaces - Time-scaled network diagrams blend of project
network and bar charts
106Chapter 6 Project Time Management
- Schedule Development Outputs (continued)
- Supporting Detail all assumptions and
constraints. May also include - Resource requirement by time period (resource
histogram) - Alternative schedules (best/worst case)
- Schedule reserve/risk assessments
- Schedule Management Plan how updates are
managed - Resource requirement updates leveling and
activity impact
107Chapter 6 Project Time Management
- Schedule Control
- Influencing factors which create schedule changes
to ensure changes are beneficial - Determining that schedule has changed
- Managing actual changes as they occur
- Inputs to Schedule Control
- Project Schedule baseline approved, measure
against project performance - Performance Reports planned dates met, issues
- Change Requests
- Schedule Management Plan
108Chapter 6 Project Time Management
- Schedule Control Tools Techniques
- Schedule Change Control System defines
procedures for schedule changes, paperwork,
approval, tracking systems - Performance Measurement assess magnitude of
variations to baseline determine if corrective
action is needed - Additional Planning
- Project Management Software
109Chapter 6 Project Time Management
- Schedule Control Outputs
- Schedule Updates any modifications, stakeholder
notification - Revisions change scheduled start and finish dates
generally in response to scope changes.
Re-baselining may be needed in drastic
situations
