Enterprise systems engineering (ESE) is the discipline that applies systems engineering to the design of an enterprise. [1] 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. [1]
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.[ citation needed ] [2]
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.[ citation needed ]
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. [3]
Four elements are needed for enterprise systems engineering to work. These include development through adaption, strategic technical planning, enterprise governance, and ESE processes (with stages). [4]
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, mobile phones have undergone numerous modifications since their introduction. Initially, the devices were considerably larger than those seen in later iterations. Over time, variations in size and design have been observed across different generations of mobile phones. Additionally, the evolution of mobile data technology from 1G to 5G has influenced the speed and convenience of mobile phone usage. [5]
Strategic technical planning (STP) gives the enterprise the picture of their aim and objectives. STP components are: [6] [7]
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. [8] 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. [9]
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). [10] [3]
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.[ citation needed ]
CBEA is an analysis method that focuses on elements that the whole enterprise needs. [11] The three steps are purpose formulation, exploratory analysis, and evolutionary planning:
EA is a model that illustrates the vision, network and framework of an organization. The four aspects (according to Michael Platt) are business prospects, application, information and technology. [12] The diagram shows the structure of enterprise architecture. The benefits are improvement of decision making, increased IT efficiency and minimizes losses. [13]
All the elements are dependent and rely on each other in order to build the infrastructure. [14]
Enterprise analysis and assessment aims to assess whether the enterprise is going in the right direction and help to make correct decisions. Qualities required for this step include awareness of technologies, knowing and understanding command and control (C2) issues, and using modeling and simulation (M&S) explore the implications. [15]
Activities and actions for this event include:
Traditional systems engineering (TSE) is a term to be defined as an engineering sub-system. [16] [17] Elements:
A survey compared ESE and TSE. The survey reported that the two are complementary and interdependent. ESE had a higher rating while TSE could be part of ESE. The combination could be ideal. [18]
The two types of ESE application are Information Enterprise Systems Engineering and Social Enterprise Systems Engineering.
It is a system that builds up to meet the requirements and expectations of different stakeholders in the organization. There must be an input device to collect the information and output device to satisfy the information needs. [19]
There are three different aspects for the framework of IESE:
Also, there are different rules for the IESE model. [20]
This is a framework that involves planning, analyzing, mapping, and drawing a network of the process for enterprises and stakeholders. Moreover, it creates social value for entrepreneurship and explores and focuses on social and societal issues. It forms a connection between social enterprise and system engineering. There is a Social Enterprise Systems Engineering V-model, in which two or more social elements are established based on the system engineering framework—for example, more social interface analysis that reviews stakeholders' requirements, and more activities and interactions between stakeholders to exchange opinion. [21]
There are opportunities and risks in ESE and they have to be aggressive in seeking opportunities and also finding ways to avoid or minimize the risks. Opportunity is a trigger element that may lead to the accomplishment of objectives. Risk is a potential occurrence and will affect the performance of the entire system. [22] There are several reasons for the importance of risk management. [23]
There are few steps in Enterprise risk and opportunity Management Process
Risk management is the identification, evaluation, and prioritization of risks followed by coordinated and economical application of resources to minimize, monitor, and control the probability or impact of unfortunate events or to maximize the realization of opportunities.
Systems engineering is an interdisciplinary field of engineering and engineering management that focuses on how to design, integrate, and manage complex systems over their life cycles. At its core, systems engineering utilizes systems thinking principles to organize this body of knowledge. The individual outcome of such efforts, an engineered system, can be defined as a combination of components that work in synergy to collectively perform a useful function.
Software architecture is the set of structures needed to reason about a software system and the discipline of creating such structures and systems. Each structure comprises software elements, relations among them, and properties of both elements and relations.
Information technology (IT)governance is a subset discipline of corporate governance, focused on information technology (IT) and its performance and risk management. The interest in IT governance is due to the ongoing need within organizations to focus value creation efforts on an organization's strategic objectives and to better manage the performance of those responsible for creating this value in the best interest of all stakeholders. It has evolved from The Principles of Scientific Management, Total Quality Management and ISO 9001 Quality management system.
System of systems is a collection of task-oriented or dedicated systems that pool their resources and capabilities together to create a new, more complex system which offers more functionality and performance than simply the sum of the constituent systems. Currently, systems of systems is a critical research discipline for which frames of reference, thought processes, quantitative analysis, tools, and design methods are incomplete. The methodology for defining, abstracting, modeling, and analyzing system of systems problems is typically referred to as system of systems engineering.
Enterprise architecture (EA) is a business function concerned with the structures and behaviours of a business, especially business roles and processes that create and use business data. The international definition according to the Federation of Enterprise Architecture Professional Organizations is "a well-defined practice for conducting enterprise analysis, design, planning, and implementation, using a comprehensive approach at all times, for the successful development and execution of strategy. Enterprise architecture applies architecture principles and practices to guide organizations through the business, information, process, and technology changes necessary to execute their strategies. These practices utilize the various aspects of an enterprise to identify, motivate, and achieve these changes."
The Department of Defense Architecture Framework (DoDAF) is an architecture framework for the United States Department of Defense (DoD) that provides visualization infrastructure for specific stakeholders concerns through viewpoints organized by various views. These views are artifacts for visualizing, understanding, and assimilating the broad scope and complexities of an architecture description through tabular, structural, behavioral, ontological, pictorial, temporal, graphical, probabilistic, or alternative conceptual means. The current release is DoDAF 2.02.
Business analysis is a professional discipline focused on identifying business needs and determining solutions to business problems. Solutions may include a software-systems development component, process improvements, or organizational changes, and may involve extensive analysis, strategic planning and policy development. A person dedicated to carrying out these tasks within an organization is called a business analyst or BA.
A federal enterprise architecture framework (FEAF) is the U.S. reference enterprise architecture of a federal government. It provides a common approach for the integration of strategic, business and technology management as part of organization design and performance improvement.
Technology strategy is the overall plan which consists of objectives, principles and tactics relating to use of technologies within a particular organization. Such strategies primarily focus on the technologies themselves and in some cases the people who directly manage those technologies. The strategy can be implied from the organization's behaviors towards technology decisions, and may be written down in a document. The strategy includes the formal vision that guide the acquisition, allocation, and management of IT resources so it can help fulfill the organizational objectives.
Unicom System Architect is an enterprise architecture tool that is used by the business and technology departments of corporations and government agencies to model their business operations and the systems, applications, and databases that support them. System Architect is used to build architectures using various frameworks including TOGAF, ArchiMate, DoDAF, MODAF, NAF and standard method notations such as sysML, UML, BPMN, and relational data modeling. System Architect is developed by UNICOM Systems, a division of UNICOM Global, a United States-based company.
An enterprise architecture framework defines how to create and use an enterprise architecture. An architecture framework provides principles and practices for creating and using the architecture description of a system. It structures architects' thinking by dividing the architecture description into domains, layers, or views, and offers models – typically matrices and diagrams – for documenting each view. This allows for making systemic design decisions on all the components of the system and making long-term decisions around new design requirements, sustainability, and support.
Information security management (ISM) defines and manages controls that an organization needs to implement to ensure that it is sensibly protecting the confidentiality, availability, and integrity of assets from threats and vulnerabilities. The core of ISM includes information risk management, a process that involves the assessment of the risks an organization must deal with in the management and protection of assets, as well as the dissemination of the risks to all appropriate stakeholders. This requires proper asset identification and valuation steps, including evaluating the value of confidentiality, integrity, availability, and replacement of assets. As part of information security management, an organization may implement an information security management system and other best practices found in the ISO/IEC 27001, ISO/IEC 27002, and ISO/IEC 27035 standards on information security.
ArchiMate is an open and independent enterprise architecture modeling language to support the description, analysis and visualization of architecture within and across business domains in an unambiguous way.
A glossary of terms relating to project management and consulting.
A view model or viewpoints framework in systems engineering, software engineering, and enterprise engineering is a framework which defines a coherent set of views to be used in the construction of a system architecture, software architecture, or enterprise architecture. A view is a representation of the whole system from the perspective of a related set of concerns.
The Enterprise Architecture Assessment Framework (EAAF) was created by the US Federal government Office of Management and Budget (OMB) to allow federal agencies to assess and report their enterprise architecture activity and maturity, and advance the use of enterprise architecture in the federal government.
The Business Motivation Model (BMM) in enterprise architecture provides a scheme and structure for developing, communicating, and managing business plans in an organized manner. Specifically, the Business Motivation Model does all the following:
In software engineering, a software development process or software development life cycle (SDLC) is a process of planning and managing software development. It typically involves dividing software development work into smaller, parallel, or sequential steps or sub-processes to improve design and/or product management. The methodology may include the pre-definition of specific deliverables and artifacts that are created and completed by a project team to develop or maintain an application.
TRAK, or The Rail Architecture Framework, is a general enterprise architecture framework aimed at systems engineers. It is based on MODAF 1.2.
