In rapidly changing environments, one rule of thumb applies: If you don't adapt, you don't endure. That's the core idea behind environmental scanning. Definitions of the term abound, but in essence it refers to the means by which organizations gather information on changing conditions and incorporate those observations into a process where necessary changes are made. The right information, combined with the right adaptations, can determine an organization's future viability. If an entrepreneur is not aware of what the environment surrounding his business he is sure to fail. E.g., HMT watches lost its market to Titan.
