Definition

• A Gantt chart is a graphic representation of the progress in particular portions of a project over several segments of time.
  
  

History

• The concept of a Gantt chart was developed in 1917 by Henry Gantt, an American engineer who helped bring companies like Bethlehem Steel to prominence at the beginning of the 20th century.
  
  

Strengths

• The graphic nature of Gantt charts makes them useful in easily identifying when a task needs to be accomplished as well as giving a rough estimate regarding the resources needed to achieve that certain task.
  
  

Weaknesses

• Gantt charts can become confusing in large projects, particularly in those with several tasks running through overlapping periods of time.
  
  

Common Practices

• Bars are usually used when making a Gantt chart, with time represented horizontally and particular tasks represented vertically. However, lines are also sometimes used.
