How can a designer clarify the point of a website to create a more successful website vs one of “good taste”?

While reading this article, I agree that everything that is an art form is subjective. I believe however there is a rate of successfulness dependent on what the designer wanted to accomplish in the end. Being worried about creating with good taste gets in the way of being completely creatively free and can hinder the successfulness or the end product. The thought to not “start out with a solution set (because) that has already excluded a majority of the possibilities” which makes me wonder if designers at large corporations aren’t given the final end note then how could they find a satisfying end with nothing met or really assigned. However, maybe a solution is not directly related to what is needed at the end, ie a portfolio website. I believe to clearly create a succesful website that is not necessarily related to good taste is to have an end goal and a general path (clear wireframes, static mockups etc.) to follow so the process doesn’t keep going round circle and not have anywhere to end.
