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.
Enterprise systems engineering incorporates all the tasks of traditional systems engineering but is further informed by an expansive view of the political, operational, economic, and technological (POET) contexts in which the system(s) under consideration are developed, acquired, modified, maintained, or disposed.
Enterprise systems engineering may be appropriate when the complexity of the enterprise exceeds the scope of the assumptions upon which textbook systems engineering are based. Traditional systems engineering assumptions include relatively stable and well understood requirements, a system configuration that can be controlled, and a small, easily discernible set of stakeholders.
An enterprise systems engineer must produce a different kind of analysis on the people, technology, and other components of the organization in order to see the whole enterprise. As the enterprise becomes more complex, with more parameters and people involved, it is important to integrate the system as much as possible to enable the organization to achieve a higher standard.
Elements
Four elements are needed enterprise system engineering to work. These include development through adaption, strategic technical planning, enterprise governance, and ESE processes (with stages).
Development through adaptation
Development through adaptation is a way to compromise with the problems and obstacles in complex systems. Over time the environment changes and adaptation is required to continue development. For example, the mobile phone has gone through many adaptations. When it was first released, its size was enormous, but over generations of development phones became smaller. The development of mobile data from 1G to 5G made using phones faster and more convenient.
Strategic technical planning
Strategic technical planning (STP) gives the enterprise the picture of their aim and objectives. STP components are: Mission statement Needs assessment Technology descriptions and goal statement Hardware and software requirement Budget plan Human Resources
Enterprise governance
Enterprise governance is defined as 'the set of responsibilities and practices exercised by the board and executive management to provide strategic direction, ensure that objectives are achieved, ascertain that risks are managed appropriately and verify that the organization's resources are used responsibly,' according to CIMA Official Terminology. EG allows one to make the right decision on the choice of CEO and executives for the company, and also to identify the risks of the company.
Processes
Four steps comprise the enterprise system engineering process: technology planning (TP); capabilities-based engineering analysis (CBEA); enterprise architecture (EA); and enterprise analysis and assessment (EA&A).
Technology planning
TP looks for technologies key to the enterprise. This step aims to identify the innovative ideas and choose the technologies that are useful for the enterprise.
Capabilities-based engineering analysis
CBEA is an analysis method that focuses on elements that the whole enterprise needs. The three steps are purpose formulation, exploratory analysis, and evolutionary planning:
Purpose formulation
Assess stakeholder Interest – understand what the stakeholders want and like
Specify outcome spaces – find solutions for several conditions and the goal for the operations Frame capability portfolios - collect fundamental elements
Exploratory analysis
Assess performance and cost – identify the performance and cost in different conditions and find solutions to improve Explore concepts – search for new concepts and transform advanced capabilities Determine the need for more variety – examine the risks and chances and decide whether new ways are needed
Evolutionary planning
Assess enterprise impacts – investigate the effects on the enterprise in technical and capability aspects Examine evolution strategies – explore and construct more strategies and evolution route Develop capability road map – plan for the capability area which includes analysis and decision making which is a tool for assessment and development for the enterprise
