When selecting the research method it is usually advisable to consider whether you can base your work on an earlier theoretical model. Sometimes a model, even a preliminary one, can help your work decisively, and in such a case it will also affect the logical process of analysis. There are three alternatives which are discussed in more detail later on: Exploratory Research Research is exploratory when you use no earlier model as a basis of your study.
For the Technology Architecture: Hardware, software, hosting environment such as servers, data centers and computer rooms, o Execution environment: This framework provides a formal and highly structured way of viewing and defining an enterprise.
This framework consists of a two dimensional classification matrix based on the intersection of the columns with the aspects of the architecture What, Where, When, Why, Who, How and the rows with the definition of the type of stakeholders, objectives and scope see Figure 1.
Figure 1 The basic idea underlying Zachman framework is that the same complex thing can be described using different level of abstractions and different perspectives.
A realization of the Zachman Framework can be seen in the Figure 2. Figure 2 There are several aspects to consider when realizing the framework as shown in the Figure 2. Every architectural artifact should be in exactly one cell.
A cell is considered complete when it contains sufficient artifacts to fully define the system for one specific stakeholder. And finally, cells in columns should be related to each other. For example, while the business owner thinks differently about data from the database administrator, there should be some relationship between these perspectives.
TOGAF is a method which has four modeling levels: Business, Application, Data and Technology. The business architecture defines the business goals and strategy, products and services, governance, organization and key business process. The application architecture provides a blueprint for the applications and systems supporting the business processes.
The data architecture describes the data assets, its organization and the associated data management systems. The technical architecture describes the hardware, platforms and network infrastructure.
The following diagram represents the ADM as an iterative and cyclic process see Figure 3. Figure 3 Another important component of TOGAF is the Enterprise Continuum which is a repository of artifacts involved in the design and implementation of your system such as models, patterns and other architectural work.
The preliminary phase is where we talk about the objectives, the scope, concepts, assumptions, methods and tools for EA to key stakeholders who will be involved in, or benefit from and their responsibilities.
The architecture vision phase A is where we understand the business principles, goals and strategic drivers for the organization to clarify the purposes, so a baseline for the EA as-is and target environment to-be is established.
In this phase, you may use a business scenario where you would identify in a workshop what are the business problems, business requirements and identify potential business solutions. The EA team will collaborate with the business team to understand and scope the needs.
In the practice, this phase begins with a Request for Architecture Work RAW document including the business reasons, budget and personnel information. As soon as the RAW document is ready, then the TOGAF consultant will define the project scope, identify constraints, document business needs and establish both the baseline as-is architecture and the target to-be architecture.
The output of this phase is the Statement of Architecture Work SAW document with the architectural vision high-level definitions of business, technology, data and application architectures for the baseline and target EA.
The business architecture phase phase B describes the product and service strategy, the organizational chart, business function and processes, key business process, geographic aspects to support business goals by using tools such as business process and use-case models.
You can also perform gap analysis of your baseline and target architecture. In this phase, the TOGAF consultant will create a detailed baseline and target business architecture and perform a gap analysis between them as the output for this phase.
The information system architecture phase phase C is to analyze and specify both the data and application domains.Complete: 4- to 6-page section of the SR-kf for Kudler Fine Foods Paper, Include the following: Preliminary design model: Provide a diagram that illustrates the overall logical information .
