In project planning, one of key scheduling functions is task scheduling. Sequence of tasks may have them put in mutual relationships according to 4 dependencies: start-to-start, finish-to- finish, start-to-finish, and finish-to-start. The latter is the most common: one task gets finished so the next starts. The next to last is the most uncommon: the next task won't finish before the first one starts. Look up definitions of all of those dependencies and bring up one example for any two of the following dependencies: start-to-start, finish-to-finish, start-to- finish. Discuss how your example is appropriate for the selected dependency
