In software development — especially large and complex software with many interfaces — requirements don’t always affect customers. Requirements often focus on the back-end, processing and system interfaces. This is over marketing’s head.
Why does error happen?
The common initial reaction when is to find and blame an error occurs someone. However, even apparently single events or errors are due most often to the convergence of multiple contributing factors. Blaming an individual does not change these factors and the same error is likely to recur.
What are the problems with requirements practices?

Why requirement management is difficult?
As the complexity of the project increases, impact analysis of changes on requirements and it’s interdependent requirements and user stories gets difficult. The requirements aren’t just text; they are highly structured information. They have multiple dependencies and references.
How can requirements turn bad during the requirements gathering process?
Bad Requirements – Requirements are considered “bad” if they are: ambiguous, incomplete, not verifiable, etc. When stakeholders provide and analysts document bad requirements, they result in systems which are not completed or not used.
