A Gantt Chart is good for planning but not an effective tool for control. Can you please let me know if it is true or false and why?
The answer is "true".

It tends to give too rosy a picture of project status, and fails to show the importance and consequences of meeting or not meeting deadlines along critical paths.
The answer is true. A Gantt chart is indeed good for planning, as it helps to visually organize tasks and their dependencies, allocate resources, and establish timelines for a project. However, it is not an effective tool for control.
The limitations of Gantt charts are discussed in the "Advantages and limitations" section of the Wikipedia page on Gantt charts, which you can find at http://en.wikipedia.org/wiki/Gantt_chart.
One of the key limitations of a Gantt chart is that it tends to give too rosy a picture of project status. This means that it may create an overly optimistic view of progress, making it seem like everything is on track, even when there may be issues or delays. This can lead to a false sense of security and hinder effective control and management of a project.
Additionally, Gantt charts do not adequately show the importance and consequences of meeting or not meeting deadlines along critical paths. A critical path refers to the sequence of tasks that, if delayed, would delay the overall project. While Gantt charts can display dependencies between tasks, they do not explicitly highlight the critical path or the impact of delays on the project timeline. This can make it difficult to quickly identify and address potential bottlenecks or risks that may affect the project schedule.
Therefore, while Gantt charts are valuable for planning purposes, they should be complemented with other control tools, such as regular project status updates, progress tracking, and risk management, to effectively monitor and control a project.
