one of his most significant contributions is the "administrative principles"

I advocate an exchange of experiences between the service managers of different companies under the direction of the ASME thus presenting the Data on which a management science could be based.

I highlight the contributions of TAYLOR, it was an innovator and I tried to reform the work day

He was a disciple and collaborator of TAYLOR.

I pay more attention to creating an environment that allows you to obtain greater cooperation from your workers, by setting them a well-defined task, for this he established a system of remuneration for the workers that I call Gantt bonuses and tasks.

His most relevant contribution was the development of graphic techniques to plan and control.

His studies and experiments led him to identify the 17 basic elements that could be applied in any activity to reduce movements, which he called (THERBLIGS).

I develop a process scheme, flow diagrams that allow studying complete operations and not just a special activity, for decision making by eliminating, reducing or combining operations, which are identified as transport inspection, delays and storage operations.
