INTRODUCTION
This section dedicated to planning of the
project:-
All about detail
More effort more likelihood of success
ADDING VALUE VS COST OF CHANGE
Burke (2007):-
PROJECT MANAGERS HAVE GREATEST CHANCE OF ADDING
VALUE AT THE BEGINNING OF A PROJECT
- Cost of change minimised at planning phase because it is a
“paper” exercise
- Changes later in project involve additional work, wasted
time and resources
CLASS EXERCISE
Read case study page 83 of manual
GOALS VS OBJECTIVES
OBJECTIVES
Broadly defined objective intentions
GOALS
More detailed, focused aim
USE “SMART” TO DEFINE GOALS
Specific – goals should be clearly defined, when, where
Measurable – quantifiable
Achievable – All parties must agree it is achievable
Realistic – must be physically possible to attain
Time Bound – must be driven by deadlines
“SMART” EXAMPLE
Build a road to Pretoria
Page 85
INDIVIDUAL EXERCISE
Think of a goal you wish to achieve personally
Write it down
Take the goal and write it the smart way
10 minutes
Do individually please!
DELIVERABLES
• Specific, measurable outcomes
• Must be completed for goals to be
achieved
• SMART criterion can be used to write
deliverable
• Tangible results are outcome of
deliverables
• When all deliverables complete project is
complete
EXAMPLES OF DELIVERABLES
• Obtain result of feasibility study by
01/08/2011
• Create charter by 02/12/2011
• Finalise construction drawings by
01/01/2012
ASSUMPTIONS
“……..the act or an instance of accepting without
proof. Arrogance”
• Negative connotations
• Avoidance of responsibilities
PROJECT SCOPE
P87 of manual
• Detailed document
• Contains list of all goals and deliverables
• Used to generate resource and cost
estimates
• Essential tool for guiding and controlling
project
• List of exclusions is KEY
COMMUNICATION PLAN
• Usually constructed in table form
• Type of communication and person
responsible listed
• Type of communication includes: status
reports, progress reports, forecasts etc.
• Recipients , method and frequency of
delivery listed
See p88 in manual
WORK BREAKDOWN STRUCTURE
“ …. a tool used to graphically
display the deliverables of the
project in a hierarchical fashion. It
organises the work of the project in
logical groupings and displays the
information in a tree form or an
outline form”
GANTT CHARTS - BASIC
GANTT CHART – MULTIPLE MILESTONE
GANT CHART - HOURLY
GANTT - SUMMARY
GANTT – EARNED VALUE
NETWORK DIAGRAMS AND CPA
Network diagrams illustrate graphically the
relationships between tasks
Number of different methods:-
•Precedence Diagramming Method
•Activity on Arrow Method
•Activity on Node Method
NETWORK DIAGRAM METHOD
• Identify all tasks in a project
• Sequence them
• Present tasks, predecessors and durations in a
table
• Draw a network

F C 4
G E,F 7

Identify tasks with
no predecessor
NO PREDECESSOR THEN MUST BE FIRST TASK
Identify bursts –
tasks sharing a
common
predecessor
Identify merges –
tasks with more
than one
predecessor
BURSTS Activity on Node
Precedence Diagramming Method
MERGE Activity on Node
Precedence Diagramming Method
INDIVIDUAL EXERCISE
1. Identify the Bursts and Merges in the example below
2. Draw a network for the situation using the Precedence Diagramming Method

Double-check the tasks against their predecessors

DURATION
DURATION
An activities duration will run from the start to the finish of the activity.. Time units can be expressed in hours, days, weeks, months, shifts – whatever is appropriate for the project.
For simplicity we will always use days as our time unit.
PUT DURATIONS ONTO YOUR DIAGRAM
DURATIONS
Add durations to your network as per the task box convention

DURATION
CRITICAL PATH
Calculate the critical path by adding up the durations on each path
The longest time is the critical path
Mark the critical path in a different colour on your diagram
FLOAT
Float is a measure of flexibility or surplus time in an
activity’s schedule. It indicates how many days an activity
can be delayed before if affects the project completion
date
All activities on the critical path have a float of 0
Put this onto your diagram
FLOAT
Add floats to your network as per the task box convention
ES

DURATION
FLOAT – NON CRITICAL PATH
SECOND LONGEST PATH
Total critical path duration – 2nd longest path duration = 2nd longest path float
PUT THIS ONTO YOUR DIAGRAM
THIRD LONGEST PATH
Total critical path duration – 3rdlongest path duration = 3rd longest path float
PUT THIS ONTO YOUR DIAGRAM
When a task is part of more than 1 path the smallest number is always selected for the float
EARLY START
Early start is the earliest date by which an
activity can start assuming all of the preceding
activities are completed as planned
ES = ES preceding task + duration preceding task

SUMMARY CPA

LS = ES + F
ES = ES PRECEDING TASK + D PRECEDING TASK
LF = EF + F
F = LS –ES OR LF-EF
ES 1ST TASK =1

F ON MORE THAN 1 PATH SMALLEST SELECTED
ES FROM MERGED TASKS SELECT HIGHEST ONE

CPA EXERCISES
PREPARE CPA FOR EACH OF THE EXAMPLES ON THE
NETWORK EXAMPLE SHEET
WORK INDIVIDUALLY
IMPLICATION TO THE CRITICAL PATH
• When float is used up critical path may change
• Tasks on critical path have zero float, therefore a
task with no float left will fall on critical path
• This tells us that there may be more than one
critical path AND the critical path is subject to
change
• Float in a task box represents float for entire path. If
a task is delayed, all the succeeding tasks will also
be delayed and their float days will be reduced

BUDGETING TECHNIQUES
• Carefully controlled budget good
indication of projects financial state
• Senior management VERY unhappy with
poor budget control
RESPONSIBILITY ASSIGNMENT MATRIX
- ENSURES EVERYONE KNOWS WHO IS
RESPONSIBLE
- ENABLES PROJECT MANAGER TO
KEEP TRACK OF DUTIES AND
LIABILITIES EVERYONE KNOWS WHO IS
RESPONSIBLE

RISK MANAGEMENT
DEFINITION:risk:-
A CHANCE OR POSSIBILITY OF
DANGER, LOSS, INJURY ETC
SOURCES OF RISK
Can come from internal or external sources
External – risks originate from macro –
environment, includes political and legal issues
Internal - risks come from the project or from
within the organisation, workforce problems,
inadequate resources and outdated
technologies
RISK ELEMENTS
Risks are analysed according to two variables:
PROBABILITY – measured by a %
100% - sure thing
0% - impossible to happen
70% - likely to happen
30% - unlikely to happen
After assessing probability need to asses the impact it will have if it happens
