"Enterprise engineering is an emerging discipline that studies enterprises from an engineering perspective. The first paradigm of this discipline is that enterprises are purposefully designed and implemented systems. Consequently, they can be re-designed and re-implemented if there is a need for change. The second paradigm of enterprise engineering is that enterprises are social systems. This means that the system elements are social individuals, and that the essence of an enterprise's operation lies in the entering into and complying with commitments between these social individuals."

“Enterprise engineering is rooted in both the organizational sciences and the information system sciences. In our current understanding, three concepts are paramount to the theoretical and practical pursuit of enterprise engineering: enterprise ontology, enterprise architecture, and enterprise governance.”

“When software applications became larger and larger, people such as Shaw and Garlan coined the term software architecture. This notion of architecture deals with the key design principles underlying software artefacts. In the 1980s and 1990s, people became aware that the development of information technology should be done in conjunction with the development of the context in which it was used. This led to the identification of the so-called business/IT alignment problem. Solving the business/IT alignment problem requires enterprises to align human, organizational, informational, and technological aspects of systems. Quite early on, the term architecture was also introduced as a means to further alignment, and thus analyzes and solves business?IT alignment problems, Recently, the awareness emerged that alignment between business an IT is not enough, there are many more aspects in the enterprise in need of alignment. This has led to the use of the term architecture at the enterprise level: enterprise architecture.”
