This presentation is meant to give an overview of the different size based estimation mechanisms, which could be most suited for legacy applications. This presentation will touch up on the different industry known estimation mechanisms, with focused details on Analogy and Parametric models of estimation. The presentation describes the practical methodologies, which have been piloted in the various projects that have been executed in our organization and will talk about the different situations/ projects best suited for each of the types of estimation. The presentation shares the estimation experience gained from executing legacy projects and supports the readers with some of the best practices to be adopted for estimation in legacy projects.

By the end of this session, attendees will be able to:
1. Get an understanding of different estimation mechanisms in the industry.
2. Know how to do data analysis statistically.
3. Understand different tools for statistical analysis.
