	In order to use a Gantt Chart one must have a detailed plan for the project. It is crucial that the duration of each activity within in the project has been estimated and that the interdependencies has been identified. Furthermore it is needed to know what resources are able to perform the activities as the same resource is not able to perform several activities at once. When the data is put into the Gantt Chart it should be easy to see the start and finish of all activities within the project and also see the start and finish of the project itself. It should also be possible to get an idea of which activities are dependent on each other. In Figure 1 and 2 it is hard to see exactly which activities are dependent on one another. However, it is assumed that one activity starts as soon as possible when its predecessor has been completed and that the planning of each activity does not inflict with the different dependencies. One way to help get an overview of the activities is through color coding.		In order to use a Gantt Chart one must have a detailed plan for the project.

	If you need a tool that can give you an overview of the time span of your activities and how they are dependent on one another then the Gantt Chart will be a fine choice. If your project is a small project the Gantt Chart might be one of the best tools you can use. However, if your project is big with many different activities and interrelations between these activities the Gantt Chart might not be the best solution as it tends to become too complex to get an easy overview.

	Before you begin with the Gantt Chart it is important that you have done the pre-work like making a project plan (see [[Program evaluation and review technique (PERT)]]), WBS (see [[Work Breakdown Structure (WBS)]])etc. as the Gantt Chart will not be able to do this for you and if something is left out the Gantt Chart will not inform you of this.

	'''Figure 3''' illustrates that an activity can have both a predecessor activity and a successor activity. A predecessor activity is an activity that needs to be completed before ~~you can~~ start on the next activity (Finish to Start dependency). In the example with the light, buying the lamp is a predecessor to installing the lamp. A successor activity is an activity that cannot start until the current activity has been completed (Finish to Start dependency). In the example with the light, turning on the switch is the successor activity to both installing the lamp '''and''' buying the light bulb. Depending on the size of the project an activity might have several predecessor activities and several successor activities. By adding the linkage between the activities to the Gantt Chart it also becomes possible to identify the '''critical path''' in the project. The critical path is the longest sequence of tasks that has to be completed in time for the project to be finished on the due date, or said in another way, it is the sequence of tasks that determines the earliest possible completion date of the project (See [[The Critical Path Method (CPM)]] for more information on this topic).

	When the Gantt Chart has been made and ~~you~~ have a ~~good~~ overview of the project it is '''very important''' to keep it updated. When a change to the project happens it is very important that this change is somehow converted into information that can be put into the Gantt Chart and thereby update the Gantt Chart and see what effect the change has on the project. Some changes might not affect the timetable of the project but other changes might be crucial for the outcome of the project and change the timetable drastically. If these changes are not put into the Gantt Chart but the Gantt Chart still functions as an overview of the project it can have severe consequences. <ref name="Mind"> ''https://www.mindtools.com/pages/article/newPPM_03.htm'' </ref>		When the Gantt Chart has been made and it is possible to have a overview of the project it is '''very important''' to keep it updated.

Costs is usually what most companies tend to focus on and it is therefore a weakness that the Gantt chart is completely ignorant when it comes to costs.
	* The amount of work needed for each activity is not specified. It is just an estimation of the time span. Even though the amount of work needed has been calculated and estimated it is only the time estimation which is presented in the Gantt Chart.		* The amount of work needed for each activity is not specified.

	If ~~you~~ need a tool that can ~~give you~~ an overview of the time span of ~~your~~ activities and how they are dependent on one another then the Gantt Chart will be a fine choice. If ~~your~~ project is a small project the Gantt Chart might be one of the best tools ~~you~~ can ~~use~~. However, if ~~your~~ project is big with many different activities and interrelations between these activities the Gantt Chart might not be the best solution as it tends to become too complex to get an easy overview.		If there is need for a tool that can provide an overview of the time span of a number of activities and how they are dependent on one another then the Gantt Chart will be a fine choice. If the project is a small project the Gantt Chart might be one of the best tools that can used. However, if the project is big with many different activities and interrelations between these activities the Gantt Chart might not be the best solution depending on the technology available as it tends to become too complex to get an easy overview.
	Before ~~you begin with~~ the Gantt Chart it is important that ~~you have done~~ the pre-work like making a project plan (see [[Program evaluation and review technique (PERT)]]), WBS (see [[Work Breakdown Structure (WBS)]])etc. as the Gantt Chart will not be able to do this ~~for you~~ and if something is left out the Gantt Chart will not ~~inform you of~~ this. Remember, to make a Gantt Chart is not the first thing to do when starting a project.
