Ease of Use: The chart provides flexible programming and interactive presentation setup scale.4. Possible support for special project planning software to facilitate complex calculations and dependencies, and perform “what if” analysis5. This also makes it possible to simulate different situations, for example to answer questionb. What are the 5 disadvantages of using a Gantt chart? 1.
