Imagine you have a critical path A-B-C-D of 20 days duration.

You have other path like A-B-E of 16 days duration.

Now the questions tells you that activity E increases in 3 days.

What's the situation now?.

Possible answers:

a) Nothing

b) Risk increases

Sumarized, answer B is correct.

I realize that A-B-E has become a near-critical-path (19 days). But is it enough to consider that the risk of the project has increased ??

Where is the limit to chose this answer?, I mean, instead increasing E by 3 days, what happen if we increase it by 1 day? A-B-E would be 17 days.

Is it still considered a near critical path?. Have the risk increased too in this case?.

I hope i explained myself properly :)
