1. A method for generating a graph data representation having a plurality of nodes corresponding to respective systems engineering requirements, the method comprising the steps of: accessing a first data representation of a collection of systems requirements and relationships therebetween; and generating a second data representation of the systems requirements comprising: accessing respective systems requirements of the collection of systems requirements; creating a node to correspond to each accessed systems requirement of the collection of systems requirements if a node corresponding to the accessed systems requirement does not exist; and creating an edge between the created or pre-existing node and each node corresponding to a systems requirement having a relationship with the accessed systems requirement; wherein each node of the second data representation corresponds to a different systems requirement of the collection of systems requirements and is a node of said graph data representation.
