1. A document prototyping system to create a systems engineering prototype document, the system comprising: a first document converter positioned to convert a plurality of word processing documents each having a predetermined word processing plain text document format into a plurality of documents each having a standard generalized markup language (SGML) format; a document parser positioned to parse the plurality of documents each having the SGML format into a plurality of systems engineering document templates each having a preselected systems engineering document format and a plurality of document sections; a systems engineering document format database positioned to store the plurality of systems engineering document templates therein; a user interface in communication with the systems engineering document format database to provide access to each of the plurality of systems engineering documents templates stored in the database by a user; document prototyping program product stored in computer-memory and in communication with the database and the user interface to create a prototype document, the document prototyping program product including a set of instructions capable of being executed by a computer to perform the following operations: browsing the plurality of systems engineering document templates through the user interface, selecting a subset of the plurality of document sections from the plurality of systems engineering document templates responsive to the user, and merging the selected sections into a new systems engineering prototype document having the subset of the plurality of document sections to thereby define a new systems engineering prototype document format; and a second document converter responsive to the document prototype creating software to convert the new systems engineering prototype document having the new systems engineering prototype document format into a reformatted systems engineering prototype document having the subset of the plurality of sections in the predetermined word processing plain text format.
