A Gantt chart is a useful tool in planning a church plant.

In particular, a Gantt chart will highlight:
The overall schedule of your project.
Due dates for various tasks to be completed.
Current status of tasks relative to forecast completion, ie are you ahead of schedule or behind?
Dependencies of tasks, for example, Bibles can’t be purchased until you’ve decided what Bible version your church will use!).
Who in your team is responsible for which tasks.

Gantter is a free project management app that allows creation of Gantt charts within Google’s G Suite. With this tool you can easily create useful charts without any project management experience at all.
