This approach provides a complete and well-structured framework that facilitates the integrated management of the three levels of an enterprise architecture: It is clear johas the search for a good level of alignment, between business objectives and the technologies that support them, has transformed the way IT management is conducted today in many organizations.
Education mpntilva Information Technologies Citations: Using the EA structure as a framework, these activities can be organized and grouped into processes using a value chain, as illustrated in Fig.

This occurs not only at the level of strategies for the optimal use of technologies and resources already in place for example, legacy systems, support infrastructure, etc. This process takes an up-to-date register of all the elements that configure the EA. Ojnas that the IT department is responsible for defining, operating and maintaining the enterprise architecture of an organization, the practical use of this critical relationship remains the main contribution of this work.
This layer provides details of the software, hardware and telecommunications platforms, on which the information system layer is developed, installed, and operated.
This is due to the so-called problems of the lack of alignment between IT and business [ 56 ]. It is divided into the processes identified in Fig.
The middle layer is known as the Information Systems Architecture. Processes required for developing software components Each process of the lowest level of abstraction is described, in our model, using a UML process diagram, as exemplified in Fig.
This state defines the baseline of the enterprise architecture. The Business Architecture is composed by business processes that are supported montillva the Information Systems Architecture.

Our process model identifies and brings together the activities of software development without indicating or encouraging the use of any method or practice.
We choose this de facto standard because of its particular point of view in considering different types of events like incidents, problems, request, and events they self. The Quality Management System has as its main objective to contribute to the achievement of the strategic objectives of the EA plan.
In the next sections, we describe an IT process model that is based monrilva the close relationship that must exist between EA and IT Management.

Abstract This paper focuses on the application of good practices to the development of instructional web sites. Among the activities included in this process are defining methods, tools, techniques and standards that will be used to manage risks of each EA component; developing the work momtilva structure necessary to manage risks within a risk timetable; estimating required resources to manage risks, and outlining the risk management plan.
Processes of the Business Processes Management The main product of the Business Processes Management is the set of models that represent the processes that the organization should execute to achieve its goals. It has been used since the decade of the 80s with the well-known framework of Zachman [ 4 ]. It includes processes such as capacity planning, design, installation and configuration, security, control and maintenance of the different types of networks LAN, MAN or WAN.
Processes of Software Applications and Components Management Like most of the other processes in the model, this monfilva is decomposed into one or more hierarchical levels until the lowest level of abstraction is reached. IT Service Support Processes 5.
Are examples of IT services the following: In most medium and large companies, this process is executed by an organizational unit that is positioned at the highest hierarchical managerial level. The enterprise architecture montikva represented by a set of models that describes and relates the business objectives, the business processes, the information systems monrilva the IT platform and that will be required to support the business processes of an organization or a part of it.
Chan, “Alignment between business and IS strategies: EA Planning consists of three groups of activities: The information systems that the company needs to run these business processes; and.
This model groups all IT management processes into eight categories: At the current moment, the enterprise architecture is described as it is by the time the EA planning is in progress. This process includes the set of activities necessary to define and maintain the strategic alignment between an EA and the business, monitor, and control the behaviour of each of the EA components, review their performance, notify risks, and analyze and authorize changes.
These activities are organized in the so-called support processes, located in the lower part of the value chain of the IT management model see figure 3. Nelson, “In their own words: It is, also, used to bring the control of changes in the products that are generated in the software development projects and the services provided by the IT Department.
