Enterprise systems engineering

Enterprise systems engineering (ESE) is the discipline that applies systems engineering to the design of an enterprise. As a discipline, it includes a body of knowledge, principles, and processes tailored to the design of enterprise systems. An enterprise is a complex, socio-technical system that comprises interdependent resources of people, information, and technology that must interact to fulfill a common mission.

It accomplishes all of the tasks of "traditional" systems engineering, further informed by an expansive view of the context POET (political, operational, economic, technological) in which the system(s) under consideration are being developed, acquired, modified, maintained, or disposed of.

Enterprise systems engineering may be required when the complexity being faced which breaks down the assumptions upon which textbook systems engineering is based, such as requirements being relatively stable and well-understood, a system configuration that can be controlled, and a small, easily discernible set of stakeholders.

Enterprise must produce different kind of analysis on the people, technology, components of the company in order to see the whole picture of the enterprise. As nowadays, enterprise becomes more complex with more problems and people to deal with, it is important to integrated the system in order to reach a higher standard or level for the business.

There are four important elements in order for enterprise system engineering to work. It includes development through adaption, strategic technical planning, enterprise governance and ESE processes (with different stages).

Development through adaptation is a justified way to compromise with the problems and obstacles in complex systems. As time goes by, the environment will change and it needs adaptation in order to develop continuously. To develop through adaption, it experiences different stages. For example, mobile phone has gone through quite a few adaptations in its evolutionary development from the past. When it first released, the size of the phone is enormous, while since the generation changes, phone becomes smaller. Also, it developed from 1G to 4G for wireless network which makes everything goes quicker and faster and more convenient. To sum up, it refers to the process of composing a diversity of innovative ideas and choices to the enterprise and select the one that will be successful for the next generation.

Strategic technical planning (STP) gives the enterprise the picture of their aim and objectives in the future and also an assessment on the process of organization. It brings a balance of assimilation and modernization to the enterprise. It has different components for STP.

It is defined as 'The set of responsibilities and practices exercised by the board and executive management with the goal of providing strategic direction, ensuring that objectives are achieved, ascertaining that risks are managed appropriately and verifying that the organisation’s resources are used responsibly.' according to (CIMA Official Terminology, 2005). Enterprise governance includes two aspects which are corporate governance (conformance) and business governance (performance). It is essential to understand the company and to know what must be done in order to succeed. It allows us to make the right decision on the choice of CEO and executives for the company, and also to identify the risks of the company.
