I suppose a non-design perspective would focus on implementing features rather than how the user can benefit from them most easily. Two sites may allow you to do the same thing, but one of them may be superior from a design perspective. A site that is stable, maintainable and easy to implement would be superior from an engineering perspective. The design perspective depends on engineering aspects, since the user experience would be bad if the site is broken.
