Is a representation of “work” on a Plan Gantt Board that needs to be accomplished within a defined period of time. Each activity is represented by a bar; the position and length of the bar reflects the start date, duration and end date of the activity. An activity can be assigned an owner as well as multiple resources which are required for the completion of the activity.
A project’s baseline is defined as the original scope, cost, and schedule. The project’s baseline is used to measure the project’s performance as it deviates from the original plan. If any change is approved then a new baseline is redefined as the original plan plus the approved change.
