feature creep

I worked on a project a while back that never quite solidified into a clear design plan or development goals. This was my first real experience with "feature creep," or the tendency of a project to increase in scope and requirements beyond those originally foreseen. In this case, we were making changes to the project requirements up to the day before the product was released. Feature creep delayed the release by several weeks. Feature creep cost me six consecutive nights of sleep.
