There are three major differences:
- Horizontal diagram orientation
GANTT charts are vertical. They tend to be long and way out of a single screen. Activities that are set around the same date can be found illogically on page 1 or page 4, depending on the GANTT details and complexity.
Projectmap is a horizontal diagram. As such, it can be viewed on a small screen and can show all of the activities around a specific date in single-page view. Moreover, the Projectmap timeline can be set to view the entire project on a single page, even if there are several hundred activities. The project’s overall structure was never this visible!
- Efficient use of diagram space
GANTT charts are empty. By nature, the hierarchical style drives large white areas all over the chart. It is impossible to optimize such a view to fit into a small screen and it will always exceed the optimal viewing area.
Projectmap utilizes 100% of the diagram area by building activity sequences on the same line. Such a diagram is not only more efficient but also far clearer. It displays the project status in a single view.
- Data structure
The GANTT chart is a simple hierarchical data model with multilayered task trees. In some areas, the user may choose to create two task levels and in other areas it can go up to ten levels or more. This data structure does not provide any analysis capabilities.
Projectmap uses categories (areas of activity). These categories are then built into three levels of information: High level, Planning and Details. This data structure gives the user the in-and-out experience of Projectmap, and equally as important, it opens the door for automatic analysis.
