more reliable delivery time commitments.capability to react to short-term incidents.faster and yet more profound decision making.This visualization in combination with any state-of-the-art software brings another value: the capability to quickly change one part of the schedule while seeing how this impacts the rest of the schedule. A picture says more than a thousand words. So, what is the value of a Gantt chart scheduler defining the when and who? Instead, they are a proven instrument to support scheduling. We regard Gantt charts not that much as planning tool. Literally, scheduling aims at putting the plan into action. Scheduling then breaks this down into concrete tasks with concrete times and owners (resources). It defines the desired outcome and a high-level road map to get there. Typically, planning happens before scheduling. Planning defines what and how (and how much).In that context, it is important to reflect on the difference between scheduling and planning: Today, Gantt charts are most effective, when they are used as scheduling tool to deliver operational agility. You can learn more about Gantt charts, their evolution and the general question ' What is a Gantt chart scheduler' in a separate blog post. As of today, the main purpose of the Gantt chart is to visualize activities, their timing, their dependencies and the resources needed to perform these activities. With the advent of capable software solutions, another element - beyond activities, dependencies and timing - had been added to the Gantt chart.

So other than in any workflow or PERT chart, a Gantt diagram shows activities, their dependencies and their timing. Initially, the major innovation of the Gantt chart was that it - for the first time ever - added a time element to the visualization of activities. In essence, a Gantt chart visualizes complex time- and resource-oriented planning data and a Gantt chart scheduler helps to efficiently change these data by easy-to-understand drag & drop actions.

If you want to put it into one phrase, the basic idea of a Gantt chart boils down to:
