Contingency planning throughout the organization may itself be a corporate strategy. These plans address actions that should be taken should certain human or natural events occur. Death of a key employee or delay of delivery due to a storm are examples of everyday occurrences that companies might face. Contingency plans of a corporate strategic level might include plans specifying how to handle public reaction to a chemical spill, when to implement stock sales or buyback during market swings, or whether to establish travel restrictions to avoid loss of an entire management team in an airplane crash.
