Terminology and Symbols Burst Point - Many Tasks Starting when One Finishes
Terminology and Symbols Sink - Many Tasks Finishing before One Can Start
Performing the Analysis Forward Pass - Working forward through the network to find earliest start and finish times Backward Pass - Working backward through the network to find latest start and finish times
Earliest Start and Finish Times The earliest times the tasks can start based on the constraints of the preceding tasks and their relationships to each other. So, if task A can’t finish till Monday at 5pm, task B can’t start till Monday at 5:01 pm.
Latest Start and Finish Times The latest times the tasks can start and finish based on the succeeding tasks and the ultimate finish time. If the contract says the end date for the project is March 11th, then the project has to finish March 11th.
Slack Time There are two types of slack: Free slack is float time between tasks based on the relationships of the tasks Introduced slack is the float time built into the network by contract - this is not in book, but is common in networks, also called total slack
