Successful projects are built on the foundation of precise requirements and the ability of teams to interpret, analyze, and review requirement documents. There are many customers who find it difficult to express their thoughts in words. Even if they are able to express themselves, there are many complexities that can arise due to the number of people involved, the skills of different team members, and the complexity of the domain. Without understanding the requirement documents (yes, there is a distinction between the requirements and the requirement documents), we would be on the path to making costly mistakes. Many projects suffered losses when the teams discovered the differences between intentions and implementation during the first demo.
