Non-examples of Estimation
Estimation is the process of finding an approximate value for a quantity or number using available information and logical reasoning. It involves making an educated guess based on some data or knowledge about the quantity being estimated. Estimation is often used in situations where exact values are not balance sheet available or practical to obtain. It allows us to quickly make calculations or decisions with a degree of accuracy that is sufficient for the given context. We leverage several tools for accurate estimation in our projects. Software applications enable us to create detailed project estimates, incorporating variables like time and cost.
