Reasons not to use MVC architecture for web application

Question

In the past I have primarily built all my web applications using an N-tier architecture, implementing the BLL and DAL layers. Recently, I have started doing some RoR development

Answer 1

Personally, I would rate it based on the complexity of the target application. MVC (or more structured approaches in general) lend themselves very well to large scale applications where design consistency and segregation of code is a benefit outweighing the cost of supporting the design.

If its a small site, or very few pages/controls, I would avoid sticking to strict design patterns. But that is just my preference.

As one poster said, you also have to consider the state of any existing applications, and your development team skills / experience.
