Henry Gantt’s management theory combined clearly defined work standards, worker training, and a time-based wage with a bonus for meeting the required task. He also developed a chart that let managers compare planned work with actual progress. The chart is the best-known part of his legacy, but it was one tool within a broader approach to scientific management.
How Gantt’s task-and-bonus system worked
Gantt’s bonus plan was not simply piecework. A worker kept a regular hourly or daily rate and could earn an additional bonus by completing a specified quantity and quality of work to a set standard. The standard was established through time study. This structure tied extra pay to meeting a defined task while retaining the worker’s time rate. A historical account of scientific management describes the plan this way.

Gantt treated setting a task and preparing workers to perform it as connected management responsibilities. His 1913 book, Work, Wages, and Profits, includes sections on task work with a bonus, the task idea, and worker training. Google Books’ record of the book lists those topics.
What the Gantt chart was for
The chart made work visible over time by showing what was supposed to be done alongside what had actually been completed. Managers could use it to follow production progress, see whether work was on schedule, and monitor budget concerns. OpenStax’s account of scientific management describes this planned-versus-actual function.
#1 Best Overall
That makes the chart a planning and control tool, not a complete statement of Gantt’s management theory. It represents one practical way to track work; his broader ideas also addressed task standards, incentives, training, and management’s role in organizing work.
Gantt’s wider ideas about management and leadership
Gantt’s writings show interests beyond scheduling, including wages, industrial efficiency, task setting, worker training, and leadership. The Library of Congress catalogs a 1913 edition of Work, Wages, and Profits by Gantt and provides access to digitized copies. Its catalog record identifies the edition as 312 pages. Gantt’s later book Industrial Leadership appeared in 1916; Google Books’ record provides its bibliographic details.
Rank #2
In Industrial Leadership, Gantt described the aim of scientific management as assigning a definite daily task to each person and securing a reward that made the task acceptable and agreeable. That statement connects his emphasis on defined work and incentives with his interest in management and leadership.

Gantt’s approach is best understood as a historical management system: define a task and its standard, prepare workers to meet it, reward completion, and track planned work against actual progress. The sources describing the system explain its design and purpose; they do not establish that it is universally effective or suitable for every modern workplace. Claims about present-day results require separate evidence.
