As you both discussed, you prefer Bottom Up Estimation. I am inclined to agree with you on most projects. However, there might be instances, such as small, fast projects, that might require Analogous Cost Estimating because they simply don’t cost enough to put in the effort to create an entire Bottom Up Estimation.

For example, if my boss were to ask me to quickly give him an estimation of a project within the next couple of hours or minutes, I would not sit down and start an entire Bottom Up Estimation project. However, if it was an indepth project that the company was investing a lot of time and money on, then yes, the BUE would be the preferred option.
