Breaking point
For a given option, the condition whose disappearance makes the option untenable: a level of activity, a date, a client, a person, a price. Every real option is described with its own.
What it changes for the executive
A decision that does not know its breaking points cannot be monitored; it will be defended by inertia until reality decides. Naming them before deciding is what allows revising later without losing face: one was not wrong, one reached the point one had set.
Example
Entering a neighbouring market has as its breaking point the number of clients signed at twelve months; a hire conditional on the renewal of the first client has as its breaking point the date of that renewal.
