Is Scope Creep Evil?

I have always been under the impression that scope creep is something to be avoided. Yet this research article by Gurlen (2003) challenges that view.

Gurlen (2003) argues that under certain conditions scope creep should be encouraged in order to assure that the client's specifications are correct. After all you do not want to deliver a product that does not meet specifications.

I like this article and the below YouTube video courtesy of EngPMgt as it shows the strengths and weaknesses of scope creep, and demonstrates why it needs to be managed so carefully.
