Many contractors hold an assumption about manuals and files dear and true - the bigger the better! The reasoning for this assumption is that weight is impressive to reviewers. In other words, the more time spent and trees killed to make a point or build a file, the more your company cares about the underlying requirements.
This weight, the theory goes, will surely impress DCMA. Or, better yet, they will be overwhelmed by the sheer volume of the undertaking, throw the flag and pass the system out of simple respect.
