I have experience the second system syndrome from both sides as a customer/sponsor and part of a development team.
A root cause for problems is when the team latches on to an Utopian vision of version 2, such as the desire to make the new software "flexible". In this scenario everything is abstracted to the nth degree. For example, instead of data objects that represent real-world entities a generic "item" object is created that can represent anything. One flawed idea is that we can build in so much flexibility into the software to anticipate future needs, that non-programmers will be able to just configure new capabilities. Often one goal such as "flexibility" overshadows the effort to a point that the resulting software doesn't work.
A balanced practical consideration of usability, performance, scalability, features, maintainability, and flexibility goals can bring the team back to earth. "It would be great if..." should be prohibited from the vocabulary of the team. The Scrum backlog is a good tool and the team should be heard saying often... "Let's backlog that...we don't need that for version 2."
