What is estimation?
Estimation is the process of finding an estimate or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable. The value is nonetheless usable because it is derived from the best information available.
Estimation can be viewed as an effective means to provide an answer when the individual providing the answer has some previous knowledge about the topic itself, and the estimation is an educated and experienced one in perspective. In these scenarios, estimation is effective.
