Gantt’s scheduling tool, known as the Gantt Chart, has been and still is a standard project management planning and scheduling tool. His views on worker compensation were forerunners of the human relations school of management.

Henry Gantt was an American mechanical engineer and management consultant who is best known for developing the Gantt chart, a graphical representation of tasks and work processes that continues to be used to plan, visualize and manage projects. Designed around 1912, Gantt charts were employed on major infrastructure projects including the Hoover Dam and the US interstate highway system.

As a management consultant and associate of Frederic Winslow Taylor, Gantt focused on the application of quantitative analysis to improve productivity. In addition to the Gantt Chart, Gantt is also know for his task and bonus system, a variation on the piece-rate system of Taylor. In this system, which resulted in significant boosts in productivity, workers received a task rate for the date whether or not they finished the task. If the task was finished they received the task rate as well as a bonus.

Because of his belief that worker and employee morale was a key factor in effective management, Gantt became an early spokesperson for the Human Relations School of management as well as the social responsibility of business.
