Gantt Charts

Summary

Henry Gantt, a pioneer in management science and a protege of Frederick W Taylor, is renowned for the Gantt chart, a fundamental tool in project management. This visual scheduling aid revolutionized efficiency by mapping tasks against time, enabling quick identification of delays. Gantt also advocated for worker training and development, overcoming managerial resistance by incentivizing them to teach best practices. Modern Gantt charts have evolved to include activity dependencies and real-time progress tracking.

Q & A

Who was Henry Gantt known to be associated with?

Henry Gantt was the first protege and associate of Frederick W Taylor.

What is the primary purpose of a Gantt chart?

A Gantt chart is used to graphically represent which tasks must be completed at which times to finish a project or task, showing the timeline and sequence of tasks.

How does a Gantt chart visually indicate the completion of tasks?

A Gantt chart visually indicates task completion by showing times in various units on the x-axis and tasks on the y-axis.

What impact did Gantt charts have on management practices of their time?

Gantt charts were revolutionary in the area of management because they provided detailed planning information, allowing managers to see at a glance where delays occurred and how efficiently the plant was being run.

How did Gantt charts contribute to the efficiency of project management?

Gantt charts contributed by showing the general appearance of the project schedule, which was sufficient to tell how closely the schedule was being adhered to and where attention was needed to maintain proper output.

What was Gantt's view on the training and development of workers?

Gantt strongly recommended that companies train and develop their workers, finding that workers achieved their best performance when they were trained first.

Why were supervisors initially reluctant to train workers according to Gantt's findings?

Supervisors were reluctant to teach workers what they knew for fear that they would lose their jobs to more knowledgeable workers.

How did Gantt overcome supervisors' resistance to training?

Gantt overcame supervisors' resistance by rewarding them with bonuses for properly training all of their workers.

What approach did Gantt take towards training workers?

Gantt's approach to training was straightforward: a scientific investment in the detail of each piece of work, determination of the best method, and the shortest time in which the work could be done, with rewards for both the teacher and the pupil.

How have modern Gantt charts evolved from the original concept?

Modern Gantt charts have evolved to also show dependency relationships between activities and the current schedule status, in addition to tracking and visually displaying project progress.

Why are Gantt charts still widely used today?

Gantt charts are still widely used today because they provide a clear and concise way to track and visually display the progress of projects, which is a feature found in nearly all project management software and computer spreadsheets.
