Flowcharts and Gantt charts are both effective tools to plan projects. However, when it comes to project execution, both have different uses and applications. For a complex plan with a longer duration, a Gantt chart is better, but for short term and smaller projects, a flow chart can do the trick on its own.

In some cases, Gantt charts and flowcharts are used in combination. Both types of charts can be easily made using Creately’s online flowcharting tools and Gantt tools.

Using Flowcharts for Project Planning

Flowcharts can be used to display a stage by stage progression. They effectively show a sequence of events, with the completion of one stage leading to the beginning of another. The only downside of using a flowchart for project planning is that you cannot add a time interval for each of the stage. Flowcharts of a project plan must show:

  1. A clear beginning
  2. Clearly labeled stages represented by rectangular boxes
  3. Diamond shaped boxes for decisions/quality checks
  4. A clearly defined end

The arrows show the direction of flow. In case of a decision, the ‘yes’ and ‘no’ arrows must clearly indicate how to tackle different possible outcomes. Using Creately’s flowchart designing tool, a simple flowchart for a small project can easily be made.

A small project quickly described using a flowchart

As can be seen from the diagram, a flowchart gives a nice visual representation of different stages of the project, but misses out on one of the most important elements of project planning, i.e. time. For a project to be planned and managed efficiently, it has to be timed and each stage has to be performed within a deadline.

When working on smaller projects, ones that can be completed within a day or two, a flowchart is enough. However, when working on larger projects, it is better to outline the processes using a flowchart before using a Gantt chart to get into details.

Using Gantt Charts for Project Planning

The biggest advantage of using Gantt charts for project planning is that they allow the manager to determine time duration for each activity. Gantt charts allow for effective display of task dependencies, information flows, and relationships between different activities. They do not put any emphasis on the logic controlling the decision making. Creately’s Gantt chart designing tool can be used to make charts for simple and complex projects.

Use Gantt Charts for High Level Plans

Gantt charts are perfect for high level plans and complex planning. Suppose you have a complex project to plan and the project spans over several weeks. Your first step should be to draw a mind map and come up with as many tasks and sub tasks related to the project as possible. You should then identify the main tasks and draw a flowchart using Creately’s flowchart designing tool.

After designing a flowchart, you should be able to see all essential tasks presented in front of you clearly. Now to create a Gantt chart, you need to know the exact duration that each task would take. You should calculate your deadlines in mind, allocate resources accordingly, and assign each essential task with a time frame. List the tasks and their time frame in a table:

Once you have determined the duration for essential tasks, you can identify their relationships, see if they can function independently, and add to the table:

Furthermore, you can identify if the tasks can be performed parallel to others or if they are sequential. In the example above, each task we have used is dependent on the preceding task, and therefore cannot be accomplished simultaneously with other tasks.

In a complex project, there will most likely be an opportunity to run several tasks at once. You will just have to identify which tasks can be run independently, and will have to keep checking the new tasks that become available after the completion of each task.

After identifying the tasks, drawing a flowchart and identifying the different types of tasks and their inter-relationship, enables you to easily construct a Gantt chart for a complex project.

If you are about to start a complex project, and are looking to draw flowcharts and Gantt charts to make project planning and management easier, try Creately’s diagram software. Use the flow chart to look at the bigger picture, and then use the Gantt chart to get into details.
