- Project planning
- Work Breakdown Structure,
- The Gantt Chart,
- Network Diagram,
- Critical Path Diagram,

- Using Microsoft Project to generate charts.
4What is Project Management?
- A set of techniques used for managing projects
- Origins in industry - large projects
- Bridge Building
- New Product Development
- Road Building
5What is a Project?
- Any task within an organisation that does not
fit neatly into business-as-usual - Port Tunnel
- Luas
- Development of New Engine
- Set up a Quality System in Company
- Technology Design Make project.
6What is a Project?
- Projects have the following characteristics
- Each project is specific and unique.
- Each project has a specific deliverable item when
complete. - This deliverable is aimed at meeting a specific
need or purpose. - There is usually a specific due date for
completion of the project. - Design is not necessarily a central part of the
project activity.
7What is Managed?
-
- PM focuses on the management of resources and
time in a systematic manner. - The administration of the project
- The supervision of the project
- The organisation of the project
8What is Managed?
- For the student it means
- Analysing the objectives of the project,
- Defining the tasks needed to achieve these
objectives, - Controlling the execution of them.
9Who manages the projeect?
- Large projects usually involve a project team.
10What do Project Managers do?
- Projects have 3 objectives,
- Finish on time.
-
- Meet the specifications that satisfy
- the brief.
-
- Meet the budget.
- Students are the project managers of their own
tasks!
11Importance of Planning
- Unexpected events may happen during the
- project and may cause delays.
-
-
-
- Breakdown of machinery,
- Problems with resources/supplies,
- Labour shortages, etc.
- Project planning can minimise the effect of these
unexpected delays.
12Project Planning
- What is a project plan?
- Can be as simple as a list of sequences for a
small project - Can be more complex with charts, tables, costings
etc. for a larger project
13Project Planning
- Analyse the brief,
- List the steps involved,
- Draw up a Work Breakdown Structure (WBS).
-
- A WBS is a diagram that shows
- Primary Tasks
- Sub-Tasks
14Example
- Draw up a Work Breakdown Structure for the
erection of a garden shed. - The shed will come prefabricated but will need to
be assembled. - A foundation will need to be prepared in advance.
15List of Tasks

1 Order Shed
2 Buy Blocks, Sand Cement
3 Build Foundation
4 Assemble Shed

17The Gantt Chart a Preview
- A Gantt Chart is a horizontal bar chart showing
the times for each task
18Looking at the Gantt Chart
- Delivery time for the shed is nine days,
- One day for buying materials,
- Two days for making the foundation,
- One day for assembly.
- Note
- Making the foundation is timed so that it is
ready just in time for the delivery of the shed - Could have been completed at an earlier date if
desired.
19Exercises
- Redraw the Gantt chart so that the maximum
amount of time is allowed for the curing of the
foundation.
20Exercises
- Shown is a picture of a Christmas Tree Star
- Draw a WBS for the Star
- Draw a Gantt chart for manufacturing the Star

24Network Diagrams
- For larger or more complex projects a network
diagram is required. - Network Diagrams show
- The relationships between the tasks,
- 2. The sequence in which each task is
performed, - 3. The interdependencies between the tasks.
25Drawing up a Network Diagram
WBS
Network Diagram
Gantt Chart
- Start with task list and draw up a WBS
- Decide on the order of tasks
26Sample WBS
A WBS needs to be analysed and redrawn frequently
to arrive at the best production sequence. (Use

30Network Diagram for Garden Shed
- Draw up a network diagram for the garden shed
project described previously.
31Some Definitions and Terms
- Terms used for network diagrams
- Activity A task or set of tasks required by the
project. - Network Diagram of nodes representing
activities connected by directional arrows that
defines the project and shows the relations
between all of the activities. Networks are
usually drawn with a Start node on the left and
a Finish node on the right. - Path A series of connected activities in the
network - Critical Path the set of activities on a path
from the projects start event to its finish
event that if delayed, will delay the completion
date of the project. - Critical Time The time required to complete all
activities on the critical path.
32 Adding Times to the Network Diagram
- Duration of each task can be added to network
diagram - From this, start and finish times can be found
for each task - Some tasks can be allowed to vary their start and
finish times without affecting overall time taken -
33Example
Consider the following project
Task Predecessor Duration
A - 5 (days)
B - 4
C A 3
D A 4
E A 6
F B,C 4
G D 5
H D,E 6
I F 6
J G,H 4
34Network with Tasks Times
35Adding Further Information
- We can add the following information to each node
in the diagram - Earliest Start Time (EST)
- Earliest Finish Time (EFT)
- Latest Start Time (LST)
- Latest Finish Time (LFT)
36Critical Path Diagram
See notes for a detailed explanation
37Conclusions from Critical Path Diagram
- Critical path is path that requires the most time
(A-E-H-J) - Critical time is 21 days which is the earliest
possible completion time - Any delay on critical path will delay the project
- Some delay (within limits) can be tolerated on
other tasks.

40Calculating Activity Slack
Slack or Float is the amount of time a
non-critical task can be delayed Slack Latest
Finish Time Earliest Finish Time or
Latest Start Time Earliest Start Time

41Slack Times from Shed Example
- Both non-critical tasks have a slack of
- (9-3)(7-1)(7-1)(6-0) 6 days
42The Gantt Chart
- Generated from network diagram
- Gives visual representation of activities and
times - Gantt charts can show
- Timeline for each task
- Dependencies of tasks
- Critical path

46Application of PM to Tech. Projects
- Now we will apply the techniques we have met to a
hypothetical LC project. - The procedure for project work is
- List the tasks and sub-tasks involved
- Draw up a WBS
- Draw up a Network Table
- Draw up a Network Diagram
- Insert times and determine the Critical Path
47Consider the following project brief
- Design and manufacture a personal alarm that will
incorporate an electronic circuit as well as a
suitable casing - From analysing the brief
- General plan on how to approach the project
- Identify the main tasks involved
- Derive a Work Breakdown Schedule
- Draw up a Network Diagram
- Add times and find the critical path, critical
time and slack for the activities.
