Definition of Project
• A project (such as construction of a flyover, power plant, research & development work, repair & maintenance of an airplane, marketing of a new product etc.) may be defined as a “collection of inter-related tasks or activities which must be completed in a specified time according to a specific order (or sequence) and require resources such as money, materials, manpower, facilities, space, etc”.

Questions to be Answered by a Project Manager

• If any activity is delayed, what effect will this have on the overall completion of the project?
• If there are additional funds available to reduce the time to perform certain activities, how should they be spent?
• What is the probability of completing the project by due date?

Limitations of Bar Chart
• Bar chart can not show clearly the interdependencies among various activities.
• Bar chart does not show the progress of work, therefore can’t be used as control device.
• Bar chart can’t reflect the uncertainties or tolerances in the duration times estimated for various activities.
![Page 15: 4a4a3PM Session 1 Introduction.ppt](https://reader035.vdocument.in/reader035/viewer/2022062322/563dbb22550346aa9aaa8968/html5/thumbnails/15.jpg)
Milestone Charts
• For dynamic programming, knowledge of amount of work in progress or jobs completed is necessary.
• Suppose 10th weeks have elapsed, what progress is made?

Exercise 2 - Represent on Gantt Chart
• A project is to be represented by a bar chart. The duration for each activity is in days work . These are the actual work days. The project commenced on Monday – 7th June 2010, with five working days a week. Draw the Gantt chart with horizontal scale denoting calendar dates. The activities duratio are shown in next slide.
• Activities 1 & 2 can occur concurrently. Activity 3 can take place after activity 2 is completed. Activities 4,6, and 3 can occur concurrently. Activity 8 can start 4 days after the commencement of activity 6. Activity 7 should follow activity 5. Activity 5 can begin concurrently with activity 8.
