Introduction to Gantt Charts

Gantt charts are one of the most popular and useful ways of showing activities displayed against time.   The position and length of a bar in a Gantt chart reflects the start date, duration and end date of a particular activity.   Gantt charts allow the following to be seen at a glance: What activities are involved in a project When each activity will begin and end How long each activity will last for Where activities overlap in time and for how long Start and end of overall project   Additional information that can be shown in a Gantt chart: How tasks relate to each other Current status of each task Resources required for each task Who a task has been assigned to

When scheduling activities: Schedule them in such a way that sequential actions are carried out in the required sequence. Ensure that dependent activities do not start until the activities they depend on have been completed. Where possible, schedule parallel tasks so that they do not interfere with sequential actions on the critical path. While scheduling, ensure that you make best use of the resources you have available, and do not over-commit resources. Allow some slack time in the schedule for holdups, overruns, failures, etc.
