How will you find critical paths for network diagram having relationships other than Finish to start?

START TO START WITH SAME DURATION

FINSH TO FINSH

ALL LEED TO critical paths

it is very easy from msproject only push a button to find the crtical path

The Longest Duration Path will give you the information for the critical Path. Draw the network diagram and calculate the longest path. The longest Path with max duration will give you the critical path.

Perform forward pass analysis and backword pass analysis to identify the tasks with0 float. The critical path is composed of the consequtive tasks with0 float.

1. FINISH TO START
2. FINISH TO FINSH 
3. START TO FINISH 
4. START TO START
