Title: Introduction to Project Management


1
Introduction to Project Management
  • A basic introduction to common project management
    processes that may be typically encountered
    during a projects lifetime.
  • Complied by AlNik Solutions for project managers
    using PMPlan products.

2
Roberts Rules of Order for Project Management
  • Get a project charter
  • Create the project scope statement
  • Create the WBS with the project team
  • Create the activity list from the WBS
  • Sequence the activities in the order in which
    they must or should happen
  • Estimate the time of the activities based on
    which resources you have to complete the
    activities
  • Assign the needed resources to the activities
  • Get it done.

From Real Life Project Management Managing the
Project Scope by Joseph Phillips Jan 28, 2005

Agenda of Presentation
  • General Project Management
  • Work Breakdown Structure
  • Scheduling
  • Earned Value Management

4
Common Project Processes
  • Initiation
  • Defines the project objectives and grants
    authority to the project manager.
  • Planning
  • Refines the project objectives and scope and
    plans the steps necessary to meet the projects
    objectives.
  • Executing
  • Puts the project plan into motion and performs
    the work of the project.
  • Controlling
  • Measures the performance of the executing
    activities and compares the results with the
    project plan.
  • Closing
  • Documents the formal acceptance of the projects
    product and brings all aspects of the project to
    a close.

5
Elements of a Projects Life Cycle
Client Statement of Work
Project Monitoring
Revised Project Plan
Preliminary Project Plan
Project Execution
Internal Review
Work Authorization
Client Requested Changes
Proposal Project Plan
Baseline Project Plan
Client Review/ Negotiations
PMPlan can be used effectively for most of the
elements of a projects life cycle.
6
Managing the Triple Constraint
  • Project Scope
  • How much work is to be done? Increasing the
    scope causes more work to be done, and vice
    versa.
  • Time
  • The schedule of the project. Modifying the
    schedule alters the start and end dates for tasks
    in the project and can alter the projects
    overall end date.
  • Cost
  • The cost required to accomplish the projects
    objectives. Modifying the cost of the project
    generally has an impact on the scope, time, or
    quality of the project.

Project Manager Roles and Interactions
8
Elements of Developing a Project Plan
Activity Definition
Activity Sequencing
Client SOW
Schedule Development
Activity Duration Estimating
Resource Pool
Work Breakdown Structure
Project Plan Development
Resource Planning
Cost Estimating
Work Packages
PMPlan can address these elements when developing
the project plan.

What is a Work Breakdown Structure
  • The Work Breakdown Structure (WBS) is the
    foundation for defining the projects work as it
    relates to the objectives and establishes a
    structure for managing the work to its
    completion. The WBS defines
  • the projects work in terms of activities that
    create deliverables.
  • the projects life-cycle process, in terms of
    process steps appropriate to that project and
    organization.
  • And is the basis for establishing
  • All of the effort/cost to be expended to create
    the deliverables and supporting processes.
  • The assigned responsibility for accomplishing
    and coordinating the work.
  • (from the PMI Practice Standard for Work
    Breakdown Structures, Oct 2000)

10
Good WBS Design Principles
  • The 100 Rule
  • The WBS defines 100 of the work of the project
  • Anything that isnt defined in the WBS is outside
    the scope of the project.
  • The work content on any item is the sum of what
    is included under that work item
  • Upper Levels are Planned outcomes (deliverables),
    not planned actions
  • Ends of WBS include the activities needed to
    create the project deliverables
  • Mutually-exclusive elements
  • Work should only appear in one place in the WBS
  • WBS must be consistent with the way the project
    will be performed and controlled
  • Must be easy to update

11
WBS Role
  • Partition the major project deliverables into
    smaller components to improve the accuracy of
    cost estimates
  • Provide a mechanism for collecting actual costs
  • Provide a mechanism for performance measurement
    and control

Why create a WBS?
  • Cost Estimating
  • Cost Budgeting
  • Resource Planning
  • Risk Management Planning
  • Activity Definition

16
Scheduling
  • Scheduling forces
  • Quantification of discrete effort
  • Placement of tasks in proper relationship
  • Two most common scheduling methodologies
  • Bar Charts (aka Gantt Charts)
  • Critical Path Method (CPM) using Precedence
    Diagramming Method (PDM)

17
Bar / Gantt Charts Defined
  • Analyze and specify the basic approach in
    execution
  • Segment into reasonable number of activities
  • Estimate the time required to perform each
    activity
  • Manually places activities in time order
  • Sequential performance
  • Parallel performance
  • Adjust to specified completion time

18
Bar / Gantt Charts Advantages
  • Plan, schedule and progress are all depicted
    graphically on a single chart
  • Easily read
  • Provides simple way to schedule small undertaking
  • Provides summary display of more detailed plans
    and schedules
  • Best used for management briefings

19
Bar / Gantt Charts Disadvantages
  • Planning and scheduling are considered
    simultaneously
  • Simplicity precludes sufficient detail for timely
    detection of slippages
  • Activity dependencies cannot adequately be shown
  • Difficult to determine how activity progress
    delays affect project completion
  • Difficult to establish and maintain for large
    projects.

21
Critical Path Method Advantages
  • Identifies activities that control the project
    length
  • Determines shortest time for completion
  • Identifies activities that are critical (i.e.
    cannot be delayed)
  • Shows available float for non-critical activities
  • Allows evaluation of what-if scenarios
  • Allows monitoring control of fast-track
    projects
  • With software can be resource loaded and leveled

22
Critical Path Method Disadvantages
  • Only as good as the effort put forth to properly
    model the plan
  • Can be difficult to properly update
  • Can be easily misused
  • May lead to a false sense of security
  • Actual conditions may necessitate significant
    modifications to model to accurately reflect
    reality

23
Precedence Diagramming Method (PDM)
  • PDM network rules
  • Activities are represented by boxes or nodes that
    are assigned properties of the activity they
    represent
  • Precedences are shown by arrows that have both
    direction and time properties
  • Precedences consist of two parts A relationship
    and a lag value or constraint
  • Finish to Start FS
  • Finish to Finish FF
  • Start to Start SS
  • Start to Finish SF

Lag x Days ( a negative lag is called a lead)
24
PDM Precedence Diagram
  • PDM activities are comprised of
  • Activity descriptions
  • Nodes representing the activity
  • Arrows representing relationship / dependency
  • Points indicating direction of relationship /
    dependency

25
PDM Logic Relationships
Finish to Start (FS) Activity A must Finish
before Activity B may Start. The lag is usually
zero. FS is the most common type.
Start to Finish (SF) Activity A must start
before Activity B may Finish. The lag is usually
greater than either activity duration. FS is the
least common type.
26
PDM Logic Relationships
Finish to Finish (FF) Activity A must Finish
before Activity B may Finish. The lag value is
usually greater than zero. FF is a less common
type.
Start to Start (SS) Activity A must Start
before Activity B may Start. The lag value is
usually greater than zero. SS is a less common
type.
27
PDM Time Calculations
  • Once the Network is constructed and duration of
    each activity is estimated, we can determined the
    following four time values
  • Earliest Start (ES) The earliest possible time
    an activity can begin
  • Earliest Finish (EF) The earliest possible time
    an activity can finish
  • Latest Start (LS) The latest possible time an
    activity can start without delaying project
    completion
  • Latest Finish (LF) The latest possible time an
    activity can start without delaying project
    completion

28
PDM Time Calculations
  • ES and EF are determined by making a Forward Pass
    (left-to-right) through the Network. ES of an
    activity is equal to the latest of early finish
    times of its predecessors. EF is the total of
    the activity ES plus its duration.
  • LS and LF are determined by making a Backward
    Pass (right-to-left) through the Network. LF of
    an activity is equal to the smallest of the LS
    times of the activities exiting from the activity
    in question. LS of an activity is equal to its
    LF minus its duration.

29
PDM Activity Notation and Assumptions
  • Each activity box consists of six cells
  • For the following example assume all activities
  • Begin on the morning of the scheduled start date
  • End the evening of the scheduled finish date
  • Using a 7-day workdays per week calendar

CPM Float (or Slack) and Critical Path
  • Additional Network calculations provides other
    important information allowing analysis and
    control
  • Total Float (TF) The amount of time an activity
    can be delayed without delaying the overall
    project completion, which is equal to Late Finish
    minus Early Finish.
  • Free Float (FF) The amount of time an activity
    can be delayed without delaying the start of
    another activity. Can be determine by subtracting
    the smallest Total Float going into an activity
    from each predecessor into that activity.
  • Critical Path The path through the Network that
    has the longest total duration, thus it defines
    the shortest period of time in which the project
    may be completed.

Scheduling Basics Review
  • Two widely used scheduling techniques
  • Bar / Gantt Charts
  • Project, schedule progress depicted on a single
    chart
  • Easy to read
  • Good for management review and oversight
  • Critical Path Method (CPM)
  • Identifies activities that control the project
    length
  • Identifies activities that are critical
  • Shows available float for non-critical activities

42
Earned Value Tracking
  • Earned Value (EV) based performance measurement
    systems Link Expenditures to accomplishments

43
This review of Earned Value Concept will
  • Describe a simple project and its progress
  • Define Earned Value and related terms
  • Show how Earned Value defines project performance

44
Earned Value System
  • Can
  • Provide early (Difficult to ignore) performance
    problem identification
  • Improve financial Reporting
  • Does not
  • Recognize Critical Paths
  • Will not
  • Take management action

45
Measurement Terminology
  • Budget at Completion (BAC)
  • The sum of the total budget for a work package,
    major task, or project.
  • Planned Value (PV)
  • The scheduled cost based on the allocation cost
    items such resources and material during the
    timeline of an activity
  • Also called Budgeted Cost for Work Scheduled
    (BCWS)
  • Earned Value (EV)
  • The value of the work performed to-date using any
    reasonably accurate, mutually acceptable
    methodology for determining value (i.e. 0/100,
    50/50, 30/40/40, ratio of units completed versus
    total units, manager estimate, level of effort,
    being some examples).
  • Also called Budgeted Cost for Work Performed
    (BCWP)
  • Actual Valve (AV)
  • Total incurred costs charged to a work package by
    the companys accounting system, which can
    include labor costs, direct costs (overhead), and
    indirect costs (material, travel, and etc.)
  • Also called Actual Cost for Work Performed (ACWP)

These values are used to calculate performance.
46
Performance Terminology
  • Cost Variance (CV)
  • CV EV AV BCWP ACWP
  • Cost Performance Index (CPI)
  • The cost efficiency ratio of earned value to
    actual costs (CPI EV/AV)
  • In PMPlan, the CPI is used to calculate Estimate
    at Completion (EAC) (EAC BAC/CPI)
  • Schedule Variance (SV)
  • SV EV PV BCWP BCWS
  • Schedule Performance Index (SPI)
  • The schedule efficiency ratio of earned value
    accomplished against planned value (SPI EV/PV).
    The SPI describes what portion of the planned
    schedule was actually accomplished.
  • Variance at Completion (VAC)
  • The predicted magnitude of possible underrun or
    overrun at completion of work package, major
    task, or project (VAC BAC EAC)

47
Review of Earned Value Concept
  • Will
  • Describe a simple project and its progress
  • Define earned value and related terms
  • Show how earned value defines project performance

Note Sample tables and graphics shown in
following slides are from PMPlan
48
Schedule
  • This shows a sample project schedule

49
Planned Budget
  • The sample project is loaded with resources which
    results in an allocated spend plan.

50
Time-Phased Spend Plan
  • This shows the time-phased spend plan if the
    project proceeds as planned.

51
Typical Approach of Tracking of Actual versus
Planned
  • The chart tells us we have spent less than
    planned to date, but
  • We cannot tell if we are behind schedule, nor if
    the cost for work completed matches the actual
    costs.

52
Using Earned Value Method
  • For Earned Value Method to work well you need to
    breakdown the project into measurable activities
    (Note in PMPlan,Cost Budgeting is done at the
    activity level not work package).
  • It is recommended that your work packages (where
    you accumulate actual costs) be one or two levels
    above the activities.
  • The following five slides show different
    performance results of our sample project.

53
Example PMPlan Earned Value Worksheet
  • The project manager or task leader enters either
    a earned percentage or a value.
  • Actual Cost is also entered. In this worksheet,
    actual cost can also include open commitments
    such as unpaid invoices for material and
    equipment.
  • The Threshold is a percent of the AV to the
    BAC, which determines when the application uses
    the CPI to calculate VAC. If AV is less than
    Threshold, the VAC equals CV.
  • Based on the data entered, this project is both
    behind schedule and over budget. Even though the
    current CV 4,000, the VAC indicates a
    potential overrun of 5,517.
  • The next slide shows two other views of this data.

54
Project has Negative SV and CV
  • In the lower half of the graph, the EV is below
    both the PV and AC indicating problems with cost
    and schedule.
  • The upper half of the graph shows both CPI and
    SPI relative to a value of 1. It is showing that
    progress is being made to improve the schedule,
    but cost problem remains.
  • The black EV bars in the Gantt schedule at the
    right shows that Design and Prototype
    activities are behind schedule.

55
Status when have - SV and zero (0) CV
  • The EV and AC are equal, thus actual cost are
    inline with accomplishments.
  • Even though the project is behind schedule, the
    schedule variance trend shows a strong
    improvement in schedule.

56
Status when have zero (0) SV, CV
  • This project is on schedule and should be
    completed under budget.
  • With the project all of the earned bars line up
    with the green status line.

57
Why 50 Complete may not be half the schedule bar!
  • In the above sample, all three activities have
    earned values of 50 of BAC, but the black earned
    bars are not the same length even though the
    planned bars are the same.
  • Task A is behind schedule, because 75 of the
    budget was to be spent by end of December.
  • Task B is ahead of schedule, because only 25 of
    the budget was to be spent by end of December.

58
In Summary an Earned Value System
  • Can
  • Provide early (Difficult to ignore) performance
    problem identification
  • Improve financial Reporting
  • Does not
  • Recognize Critical Paths
  • Will not
  • Take management action

59
Project Management Methods Summary
  • We have described three major processes used in
    project management
  • Work Breakdown Structure
  • Scheduling
  • Earned Value Management
  • We are ready now to see how PMPlan can help you
    with these processes
