Management Gantt Charts are significantly more complex and tailored than Planning Gantt Charts.
The incorporation of actual figures into the planning process significantly complicates any planning model, as anyone who has used Microsoft Project to manage a project will attest.
The significant issue with the vast majority of management Gantt Charts is that they are driven by duration rather than effort. Whilst tools such as MS Project do allow for effort driven management, the underlying premise of the tool is task driven. This can result in very unexpected results when incorporating actual figures. A key issue is that the rate of progress is seldom linear as most tools automatically assume.
With an Excel based gantt chart it is easier to build on your specific management requirements. The Chart Gantt solution provides the basics in terms of the visualisation of time. Specific management and forecasting activities can then be built around this by an experienced Excel user.
