Introduction to Project Management



2

Project

• Project is any work that has: A well defined objective / goal

Sequence of the multitudinous activities

A specific start and end

• Project Characteristics The start is known as source and end is known as sink

A project can have multiple sources (start) but will have a

single sink (end)

• Examples: Building of a dam, Bandra-Worli sea link,

Chandrayaan, Repair of a machine etc.

Project Feasibility Analysis

1. Generation of project ideaso Constrains to be considered are physical, human and

financial resources

2. Screening of generated ideaso On the basis of priority and later on available resources

3. Detailed evaluation of the screened projecto Analysis of technical feasibility

o Measurement of cost

o Measurement of benefits

o Comparison of benefits & cost

• Project Management is the scientific way of planning,

implementing, monitoring & controlling various aspects of

a project such as time, money, materials, manpower and

other resources



4

Project Planning & Control

• Tools for project planning and control Network Techniques

o Critical Path Method (CPM)

o Programme Evaluation & Review Technique (PERT)

Bar charts e.g Gantt Chart

• Comparison of Bar charts & Network techniques Bar charts does not show relationship between jobs

Charts are static

Networks shows relationship in jobs and required resources

Problem 1

For a project consisting of several activities, the duration and required resources

to carry out each of the activities and their availabilities are given below:-
