1. A method for adjusting display of a dependency on a Gantt chart, the method comprising: configuring, by the computer system, an administration interface to provide access to a configuration mode, wherein the configuration mode allows: remote administrator definition of a first set of end-users for whom a first set of dependencies are permitted to be visible and a second set of end-users for whom a second set of dependencies are permitted to be visible; remote administrator definition of end-user ability to control one or more dependencies of the first set of dependencies and of one or more dependencies of the second set of dependencies; and remote administrator definition of default display states of one or more dependencies of the first set of dependencies and of one or more dependencies of the second set of dependencies; receiving, by the computer system, a first visibility indication that indicates an end-user corresponds to the first set of end-users for whom the first set of dependencies are permitted to be visible, wherein the first set of dependencies comprises the dependency; receiving, by the computer system, a second visibility indication that indicates the end-user does not correspond to the second set of end-users for whom the second set of dependencies are permitted to be visible; receiving, by the computer system, a default display state indication that indicates a default display state of the dependency; receiving, by the computer system, a first indication that indicates the end-user is permitted to control display of the dependency; wherein one or more of the first visibility indication, the second visibility indication, and/or the first indication correspond to administrator selections received via the administration interface; generating, by the computer system, the Gantt chart for display at least partially based on the first visibility indication, the second visibility indication, and the default display state indication, with the dependency visible and with the second set of dependencies hidden, wherein the dependency is graphically represented, and the dependency represents a relationship between a first element of the Gantt chart and a second element of the Gantt chart; receiving, by the computer system, a second indication that indicates to hide the dependency, wherein the second indication is based on a single input from the end-user; and generating, by the computer system, the Gantt chart for display with the dependency hidden, wherein: the dependency being hidden is at least partially based on the first indication and the second indication.
