Developments in Gantt Charts
With the rise of technology and computers, Gantt Charts have moved away from paper and can now be displayed using computer software. This allows projects to be updated in real time with greater accuracy and gets rid of the need to draw a new chart if there are changes in plans. Continual change is a feature of most projects, so the use of computers to graph Gantt Charts greatly enhances their capabilities. It is no longer required to redraw the chart with every change in plans which is undoubtedly a laborious process which leads to time wastage in itself, something the Gantt Chart strives to overcome. With the aid of computer software, Gantt Charts can be created, amended and printed in a very short amount of time. Today Gantt charts are mostly used for tracking project schedules. They clearly display the interdependencies of different tasks at hand. With the use of colour, each task can clearly be differentiated and identified, making it even more accessible to all stakeholders in a business (1). An example of a modern Gantt Chart can be seen below (Fig. 1.). The progress of each project can be seen by the darkly coloured bars. In this way, we can easily tell whether a task is completed, ahead of schedule or behind
Is the Gantt Chart enough?
In modern day business, all managers strive to improve efficiencies and cut costs as much as possible. However, is a Gantt Chart enough to display the information for a plan? The short answer is no. Typically a Gantt Chart displays;
The dates of projects and their timeline
The dependencies between plans
All of this information is undoubtedly necessary for a successful project, however, it is not enough. Things that must be included in a project plan which are not included in the Gantt Chart include;
What is the point of the project?
Who is involved in the project and what are their individual responsibilities?
When will meetings take place?
How will major decisions be made and by whom? (2)
This information is of utmost importance when creating a plan and undertaking a project. However, that is not to say the Gantt Chart isn’t useful. Gantt Charts are a powerful tool which condense and summarise information into an accessible visual graph for all. The most important information is displayed on a Gantt Chart. This allows decisions to be made quickly based on the chart, rather than spending extraneous time on leafing through pages of information which is not necessary for the decision at hand.
Many websites can be used to create Gantt Charts. We created our own sample chart for the production of bee hotels in less than 10 minutes! The different colours signify different things.
In this way we can clearly see each task, its relationship with other tasks and the stage it is at in relation to time. This is why Gantt Charts are so useful for every business! It is completely free. Some useful websites include;
We used Wrike.com to create our own chart for free. So what’s stopping you! Get planning!
It is undoubtedly true that Gantt Charts have kept up with the changes in time. They are just as applicable to the business world now as they were one hundred years ago, if not more! Gantt Charts have become more complex but their core idea remains the same: to display facts against time in a concise manner.
Come back in two weeks for the final post on Gantt Charts, where we explore the different applications of them and the famous projects they were used on. If you are not already convinced of their usefulness as a management tool, you will be left in no doubt of how they have revolutionised the world after our last post.
