 Gail Freedman Offline Junior Boarder Posts: 35 Karma: 2 Thank you received: 3 Hi Puneet, Yes, the critical path is the longest overall duration for the sequenced activities. It is not the shortest project duration and it is the shortest time possible to complete the project. Hope that helps.

 Harry Elston Offline Moderator Posts: 467 Karma: 27 Thank you received: 145 Anon: Let me try: Tasks A, B, C and D all take 5 days. A must be before B and C can start. D is the final task B and C can be run in parallel after A. The Network Diagram is: A --> B/C --->D The critical path is 15 days, not 20, because B and C can be done simultaneously (Afer A) Hope that helps. Harry +++++ Harry J.

 Anantha Narayanan Santhanagopalan Offline Junior Boarder Posts: 39 Karma: 3 Thank you received: 7 Hi Anonymous, Take this example - Dining with friends. You all go for dinner (say 3 people). Everyone orders food and start eating... Person 1 - Takes 45 mins for eating Person 2 - Takes 20 mins for eating Person 3 - Takes 55 mins for eating. Everyone can leave only after person 3 completes his/her food. So the longest path would be reaching restaurant --> Ordering food --> Person 3 finishing the dinner --> paying bills This is also the shortest time they can complete the dining. Now lets explain float as well Person 3 cannot have any slack. Meaning - he cannot attend any phone calls/use restroom, if he/she does take a break it will still delay the dining. Whereas person 2 and person 1 can take a break/do other things while they are eating. So activities in critical path ideally cannot have float. Hope this helps.
