I am finding the same issue in many areas. But I am asking myself if it is just lack of knowledge and knowhow or is it also lack of time, processes and tools for writing and maintaining requirements. My observations are that along with not knowing how to gather and write requirements people at the project level also threat them as second hand objects for the success of project. Eg: some people in agile talk about requirements being user stories with clarifications and decisions around them. Other people say that in agile requirements are conversation starters. In a way these might be good points but also it creates the impression that we should not invest quality in requirements. As it will anyhow change.
