Project duration is shorter than expected

We have assigned risks to the project schedule and the Low result we get seems unreasonably short. Do you know of any reasons for this?

Often when we do unexpected results, we do recommend a reality check. It could be the results of an error in the schedule logic or in the risk assignments. If the schedule logic is sound, then most likely if you are model impacts using statistical distributions, the low or optimistic values for the ranges are too optimistic and the combination of risks impacts is giving you the result you are seeing.
In addition, if you are using the risk outcome End Task, Cancel Task, or Cancel Task and all successors this can have an unexpectedly dramatic impact on the project duration, such that it ends early, but not successfully.
