Arise in situations where established processes offer potential solutions.
Employees continuously evaluate the company operations to hone the firm's abilities to identify, adapt to, and leverage change.

What If Analysis
Checks the impact of a change in a variable or assumption on the model.
A special case of what if analysis, is the study of the impact on other variables when one variable is changed repeatedly.
Goal Seeking Analysis
Finds the inputs necessary to achieve a goal such as a desired level of output.
