Every company has limited resources. For example, firms don't receive unlimited investment dollars from shareholders. So, companies must optimize their use of resources.
Lots of different factors, both inside and outside of a company, affect a company's operations. Examples:
Changing consumer preferences,
changing tax laws,
changing interest rates,
changing risk levels,
changing exchange rates, and
changing demand for employees and their expertise.
