My experience says: there is at least one advantage in differentiating an architect and a developer (I have been both developer and architect). If the developer designs the system, he/she will tend to push the system design towards whatever he/she knows the best in the programming language such as libraries. This will restrict the design. In fact, the developer doesn’t think about the design without thinking about how to implement it. But, the architect who is not good at writing code can think without boundaries.
