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.

Regards,
Anantha

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.
