In the traditional approach (called Waterfall) most developers never feel the owner of the code. Why did this situation happen? Because they haven’t any opinion about the technical issues related with the requirements. Business Analysts think and write uses cases (or other form to specify the requirements) to document each requirement. Then architects move all this information to technical level such as model of database and so on. Even more, there were some company (or maybe there are still companies working in this old way) that provide a framework to developers in order to standardized the development.
