Final answer:
The missing term for the classic outcomes from change is 'unintended consequences'. This concept reflects the unforeseen and perhaps undesirable side-effects that can occur as a result of actions taken during attempts to implement change.
Step-by-step explanation:
The four classic outcomes from change, which reflect the risks and the ways to avoid them, are: the disaster, the lost investment, the unintended consequences, and the ideal. The term unintended consequences refers to outcomes that are not foreseen or intended by the actions of agents. In the context of change, particularly in businesses or economic systems, such consequences can emerge due to a variety of factors including the inability of resources to move to other markets or the impact of externalities which can be either positive or negative. For instance, political decisions involving change that require sacrifices, like reduced travel or changes in energy consumption, can have significant unintended consequences if they are not carefully managed and politically supported.
