Traditional systems engineering (SE) is performed on a development project with only one or a few related systems being developed. Enterprise SE, on the other hand, must deal with deciding among many enterprise opportunities that the enterprise projects will work on. This entails several processes that are not provided for in traditional SE practice.

An enterprise SE framework (shown below on the right side of the table) was developed to characterize the full scope of SE at the enterprise level. This framework was used to evaluate several case studies as part of doctoral research in the application of SE in large organizations (Martin 2006). This evaluation focused on how they used knowledge modeling techniques identified in the research for development of an enterprise architectures.
