Notes
Soft expected task duration shoud be distinguished from a hard deadline:
- Expected activity duration is the desired task execution term. It should be realized that due to the stochastic nature of work exceeding the expected duration isn't not something extraordinary and does not require any action. (If the expected duration is never exceeded then it means that it's set too large.) Specify the expected duration in activity properties and use a text annotation to depict it at the diagram.
- On the countrary, exceeding the deadline entails certain consequences, e.g. if the tender deadline has been execeeded, the work should be cancelled. Use attached event and a sequence flow to depict this scenario. Attached event without outgoing flow is syntactically icorrect.
