English
A contigency plan should include:
Contingency mechanism: (What to do? Who will do it?)
Contingency deadline: When is the last time the contingency mechanism can be put in place?
The contingency deadline will most likely be the beta freeze. In some cases, it may be more appropriate to set it to the start of the mass rebuild or branch day. Rarely, you can use final freeze, but this should only be used for Changes that are trivially-revertable.
