  • Patent number: 11010703
    Abstract: A productivity measuring, modeling and illustrating system receives input data pertaining to the productivity of an organization to generate various productivity views using a productivity maturity model. The productivity maturity model is based on suggested actions for increasing the productivity which are received in the input data. The productivity maturity model computes various productivity gains and provides productivity levels for the productivity levers associated with the organization. Various productivity views generated to display the productivity information include a summary view that displays the productivity gains and productivity levels using different filters.
