A Gantt chart is a type of bar chart used to illustrate a project schedule. It was developed by Henry Gantt and shows the tasks, durations, and dependencies of activities within a project. The document outlines how to construct a Gantt chart by listing activities, estimating their time requirements, ordering them, and drawing the chart with start/end dates for each activity based on duration and dependencies. Gantt charts provide a simple visual representation of a project plan but can be limited in visualizing dependencies between tasks.
2. Gantt chart
This chart was formulated for providing graphic
schedule for planning and controlling of the work,
and recoding progress towards stage of a project.
A GANTT chart is a type of bar chart that illustrates
a project schedule.
It was introduced by Henry Gantt.
3. Gantt chart
GANTT charts have become a common
technique for representing the phases and
activities of a project work breakdown
structure.
4. Constructing Gantt chart
List your activities
Make a list of everything that you plan to do in the
project.
Take your methodology and turn it into a step-by-step
plan.
Breakdown your project in to number of activities.
For ex: Define Research question, Literature review, Revisit
Research question, Make research design, sample design,
collection of data, Data Analysis and Interpret solution etc.
5. Constructing Gantt chart
Estimate the time required
For each item on your list, estimate how long it will
take you to do that thing.
For ex:
Defining Research Question: 1 week
Literature review : 2 weeks
Data Collection : 2 weeks
Data Analysis : 1 days
Report writing : 3 days
6. Constructing Gantt chart
Put activities in order
What is the first thing that you are going to
do? What will you do next? What will you do
after that?
Make a note of any dependencies (i.e.,
situations where you can’t do one thing until
another is started or finished)
7. Constructing Gantt chart
Draw a Gantt chart
Give start date and end date for each activity
depends on duration of activity and
dependency of that activity.
Draw it as like graph format (x axis = date and
y axis = Activity)

10. Advantages and Disadvantages of
Gantt Chart
Advantages
Simple
Good visual communication to others
Task durations can be compared easily
Good for scheduling resources
Disadvantages
Dependencies are more difficult to visualize.
Minor changes in data can cause major changes in
the chart.
