Gantt Chart Reason#1: Put aside distractions and focus on your plan

Planning requires deep concentration.  Try to avoid getting distracted during your planning time.  Perhaps try working from home for a day, or lock yourself in the boardroom with “busy” posted on the door.  The level of concentration and analysis you can put into your plan upfront will pay significant dividends down the track.  Usually the creation of a gantt chart involves the expenditure of cash or resources on a series of tasks.  The better though out your plan from the outset, the greater your saving during the execution phase.  A gantt chart is a great tool to help you get your thoughts in order.

Gantt Chart Reason#2: Think about the relationships between tasks

A key benefit of being able to visualize the relative timing of tasks, is to better understand the impacts of your plan, and better visualize relationships, which simply cannot be seen by looking at rows of data.  Your Gantt Chart should clearly identify relationships if possible as these relationships can be used to simplify and automate the management of your project.  By creating dependent relationships between tasks in your Gantt Chart, you are able to have any slippages automatically reflected throughout the plan.

Gantt Chart Reason#3: Flip between views (daily, weekly and monthly) get a better overview of your plan.

If you are stuck in a daily view of your gantt chart, it is sometimes difficult to see the forest for the trees.   Ensure you “step back” from your plan, but zooming in and out on your timescales to investigate particular issues.

Gantt Chart Reason#4: Plan further ahead than you feel comfortable doing
A good gantt chart tool will enable you to plan well in advance.  Sometimes visualizing longer term plans can feed back to changing your short term plans.  A good gantt chart should let you plan at least 10 years in advance, however be able to change your view so that the entire planning range can be visualized on one page.

Gantt Chart Reason#5: Analyze your resource allocation to tasks to ensure you are not “Double Dipping” on resources
Using a Gantt Chart, you can easily see periods when a resource is scheduled on multiple tasks.  If this scheduling is a full time allocation to each task, then something as to give.  A gantt chart enables you to see these emerging issues in advance and take evasive action, otherwise known as project management.
