Floats or Slack

Correct Answer: This task can be delayed up to 12 days without delaying the project.

The Total Float or Slack is the amount of time that you can delay a task without delaying the project. More slack means more flexibility. So the answer 'This task can be delayed up to 12 days without delaying the project.' is correct. The answer 'This task needs 12 extra days for completion.' is incorrect as the float does not imply a need for extra time, but flexibility with existing time. The option 'The project should be completed 12 days earlier.' is also incorrect as the float does not indicate an early completion of the project. The last answer 'The task 'Design User Interface' is not important.' is misleading - while tasks with more float may not be on the critical path, they can still be important.

Correct Answer: The task can be delayed up to 7 days without affecting the project's end date.

In project management, 'slack' or 'float' refers to the amount of time a task can be delayed without causing a delay to subsequent tasks or the project's completion date. If a task has a slack of 7 days, it means it can be postponed by up to 7 days without impacting the overall project timeline. This allows for flexibility in scheduling non-critical tasks. Therefore, the task can be delayed up to 7 days without affecting the project's end date.

Correct Answer: The 'Roof Installation' task is behind schedule.

In project management, 'slack' refers to the flexibility in the schedule of a particular task without affecting the end date of the project. When 'slack' is negative, it indicates that the task is behind schedule. Thus, 'Roof Installation' task is likely behind schedule. The idea that it's completed ahead of time (Answer 149275) is wrong because negative slack indicates a delay, not an advancement. Additional resources might be a solution to cope up with the delay but a negative slack basically does not indicate that in the first place (Answer 149276). Finally, having a negative slack is not normal and indicates a problem with the task schedule (Answer 149277).
