considering real life situation, suppose have assigned work 3 people(say person a, person b, person c), instead of waiting them complete task each, want when each person completes assigned tasks, he/she notify me distinctly. can take further decision based on his/her task.

i want implement situation in code, out using separate thread , delegates, mean using nsnotification.
