project management-cpm and pert methods for managersNaganna Chetty
A project is a one shot, time limited, goal directed, major undertaking, requiring the commitment of varied skills & resources.
A project:
Has a unique purpose.
Is temporary.
Is developed using progressive elaboration.
Requires resources, often from various areas.
Should have a primary customer or sponsor.
The project sponsor usually provides the direction and funding for the project.
Involves uncertainty.
Project managers work with project sponsors, project teams, and other people involved in projects to meet project goals.
Program: “A group of related projects managed in a coordinated way to obtain benefits and control not available from managing them individually.”
Program managers oversee programs and often act as bosses for project managers.
Project management is “the application of knowledge, skills, tools and techniques to project activities to meet project requirements.”

Critical Path Method
Introduction
Once you have the network diagrams for the activities, as well as the activity duration estimates, you can begin scheduling the project. The critical path method (CPM) is one of the key techniques for developing a project schedule.
In a schedule network diagram, the critical path is the longest full path linking activities that must be performed in sequence. It's important to identify this path, because if one of its activities is delayed, the end date of your project is delayed too.
CPM provides a way to calculate four time boundaries:
· the early start date, which is the earliest possible start date for each activity to begin
· the early finish date, which is the earliest date each activity can end
· the latest start date, which is the latest possible time for each activity to begin
· the latest finish date, which is the latest date each activity can end
CPM involves completing three steps:
1. performing a forward pass through the network diagram
2. performing a backward pass to check your initial results
3. calculating the float for each activity to determine the critical path
The forward pass
The first step in CPM is performing a forward pass through the schedule network diagram so you can establish the early start and finish dates for each activity. This is done so that resources, such as project team members and equipment, can be allocated as soon as possible. Allocating resources assists in determining project expenditure and therefore establishing the project budget.
When performing a forward pass, you begin with the first activity in the network diagram and move forward. You
1. record the earliest date the first activity can start
2. add the duration of this activity to the early start date
3. subtract one day from the result
Some project managers find it useful to record activities' start and finish times in the network diagram. The early start is usually filled in on the top left corner of each activity block, with the early finish date shown in the right corner.
The backward pass
The second step in determining the critical path for a project is to perform a backward pass through the schedule network diagram.
You perform the backward pass to establish the latest start and finish dates for the project to remain on schedule.
In a backward pass, you start at the end of the project and work back, subtracting the estimated duration of each preceding activity.
To begin the backward pass, the late finish date will either be a hard date that's been set or the early finish date of the last activity in the project. An example of a hard date may be a deadline that determines the project's end date.
To calculate the late start date, you
1. subtract the duration of the last activity from its late finish date
2. add one day because the last day of the project is included as a working day
As you work backward through the schedule network diagram, the late finish date will fall on the working day preceding the lat.
A project is an interrelated set of activities that has definite starting and ending points and that result in a unique product
or service
• Cuts across organizational lines - they need varied skills of different profession
• Uncertainties like new technology & external environment can change the character of the project
• Personnel, materials, facilities etc. are temporarily assembled to accomplish a goal within a specified time frame and then disbanded
• Upon finish, a project releases lot of resources which were engaged in execution of the project

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2. Overview of lecture
O Introduction to CPM - Critical Path
Method
O Steps to use Critical Path Method
O CPM - Advantages
O CPM - Disadvantages
3. Introduction
O CPM stands for Critical Path Method.
O CPM is a project schedule modeling technique
developed by Mr. Morgan R. Walker and James E.
Kelly in the late 1950s.
O CPM is based on the estimation of the standard time
needed for execution of a activity.
O CPM manages the both time and cost of the project.
4. Introduction
O In this method, the critical path of the project is
established by identifying the critical activities of the
project.
O Critical activities are the activities whose total float value
is ‘0’.
O The Critical Path is the longest sequence of activities in a
project plan which must be completed on time for the
project to complete on due date.
O CPM is commonly used in conjunction with the Program
Evaluation and Review Technique (PERT).
6. Step 1
Identify activities based on WBS
O The WBS (Work Breakdown Structure), describes
deliverables, not activities. This is why all its components
are described using nouns or adjectives, not verbs.
O The CPM, however, focuses on activities described using
verbs.
O The first step of the CPM process, therefore, is to list all
the activities required to create deliverables at each level
of the WBS.
7. Step 1
Identify activities based on WBS
Figure- a
O This list of
activities as in
figure-a , will
form the
foundation of the
CPM
8. Step 2
Identify all dependencies
O Any project has two types of tasks.
O Tasks that depend on other tasks for their completion, i.e.
dependent tasks
O Tasks that are independent of others and can be done in
parallel to others, i.e. concurrent tasks
O The next step in the CPM process is to establish which of the
tasks are dependent and which are concurrent
9. Step 2
Identify all dependencies
O Go through the list of activities and identify which tasks each
depends on, and in what order, as follow:
O A list of dependent tasks is called an activity sequence.
These are used to figure out the critical path
10. Step 3
Create a network diagram
O Once you’ve identified all tasks and their dependencies, it’s
time to create a network diagram, also known as a critical
path analysis chart.
O This chart visualizes separate activity sequences and enables
you to map dependencies easily.
O To create it, make a list of all activity sequences.
O Create separate boxes for each task in the sequence.
11. Step 3
Create a network diagram
O Next, use arrows to identify dependencies between tasks
in each sequence, as follow:
12. Step 4
Estimate duration of each activity
O We first need to estimate the duration of each activity. The
activity sequence that takes the longest time would then be our
critical path.
O List the duration (t) of each activity next to its name in the
network diagram.
14. Step 5
Calculate the Critical Path
O In the network diagram, write down the start and end time of
each activity next to its box.
O The first activity in the sequence would have a start time
of ‘0’. Mark the Start Time to the left and End time to the right
of the first activity. (Usually, this would be 0). Its end-time would
be its duration.
O The second activity’s start time would be the end-time of the
first activity. Its end-time would be the start time + the duration.
15. Step 5
Calculate the Critical Path
O In this way now mark the Earliest Start (ES) time of each
activity. This is given by the largest number to the right of the
activity's immediate predecessor (i.e. its Earliest Finish time, or
EF).
O If the activity has two predecessors, the one with the later
EF time would give you the ES of the activity.
17. Finally
O The activity sequence with the longest duration would be your
critical path as shown below:
18. CPM - Advantages
O CPM shows a graphical view of the project.
O CPM helps the project manager in identifying the most
critical elements of the project.
O CPM provides demonstration of dependencies which helps
in the scheduling of individual activities
O CPM aids in project planning, scheduling, and controlling.
19. CPM - Disadvantages
O For bigger projects, CPM networks can be too
complicated.
O CPM also does not handle the scheduling of the resource
allocation.
O CPM does not consider resource dependencies.
O There is a chance of misusing float or slack in CPM
method.
