Describe the Enterprise Architecture Applications For Graphical Modelling.
Answer:
Introduction
Archimate is an independent and open tool for performing the graphical modelling of enterprise architecture. With the assistance of TOGAF the notation of the Archimate is been evolved. The Archimate is a view point that helps us to understand, communicate and document the enterprise architecture. It gives a clear vision about the business domains. The Archimate core defined by the TOGAF, the motivation of this project is to provide viewpoint for the stakeholders, to view the target architecture, to analyses the goals of the business along with the requirement and principles. The analysis of the GAP and the target architecture is will be provided. This project provides a clear vision of the Business Architecture starting from week 4 to week 11, it also explains the application, business and system view of the enterprise architecture. An architecture vision for the stakeholders concern will be provided and the baseline business functions of the enterprise and the organization architecture will be provided.
A visual language that is used to capture the whole enterprise architecture is offered by the Archimate tool. It includes processes, services, technical and data application of the organization and the products and services. The Archimate tool is been used for the view point of the stakeholders and to address the variety concern. The ArchiMate tool provides three layers business, application and system/ technology. The services provided for the customers is been given in the business layers, the application support that is provided to the organization is provided in the application layer and the technical infrastructure is given in the technical layer (Saha, 2012).
TOGAF is expanded as The Open Group Architecture Framework, that gives a clear description about the supporting tools that is been used for developing the Enterprise Architecture.
Commercial architectural assets involves
- Business practices, business processes and business polices.
- Information entities or concepts, relationship to the process of business.
- Interfaces, relationship and the applications to the process of business.
- Relationship and technologies to the applications.
The entire formal Enterprise architecture methods possess best practice which involves
- establishment of target architecture
- Establishment of baseline architecture
- Gap analysis performance
- Architectural roadmap development Migration plan development
Start with converting existing environment description into TOGAFA. It permits the team to improve the architecture to get experience having the model and understanding their components. Few adaptation might be needed to match the definition of the architecture methods is explained in the process. Set down the key questions which is the significant part of the task. It is used in the development process for measuring the new architecture effectiveness.
All relevant concepts of the Archimate and the Enterprise Architecture is been given in the viewpoint of the ArchiMate. In the viewpoint of the stakeholders concern the organization infrastructure, vision, mission and goals is provided in the diagram. The following diagram provides the view point for the stakeholders concern.
The main functions that is been carried out in the organization is been given in the business function diagram. It includes the business functions like customer relationship management, risk management, financial auditing, marketing and service level management (Rosenfeld, Morville and Arango, n.d.).
In Baseline Business process, the address of the level of detail depends on goal and scope of the whole architecture effort. The process of new business needs to be defined. In Baseline Business process, steps to be followed which is mentioned below.
- Development of baseline business architecture description
- Performance of gap analysis
- Choose viewpoints, tools and reference models
- Resolve the business architecture
The TOGAF phase C Information architecture has two parts that are data and application architecture. The aim of the application architecture is to progress the target application architecture (Perks and Beveridge, 2011). It supports the business architecture and the architecture vision, during the process of addressing the request for architecture work and the stakeholder fears. It is used to find out the roadmap components, that is depend on the GAP between Baseline and target architecture.
The Goal refinement view enables the designer to change the level of refinement goals. The high level refinement goals is modeled into the many concrete level refinement goals. The concrete level refinement goals is changed to requirements. It defines the properties. The properties are required to utilize a goals. The requirement get from the refinement of goals is demonstrated by the help of Realization relationship.
The target architecture is the desire architecture that is to be framed in the future. The GAP analysis is nothing but a method of measuring the changes present in the performance of a Business Information Systems. It is needed to regulate whether Business requirements stand being encountered or not, If the requirement is not encountered what are steps needed to safeguard the business. The GAP analysis is performed to achieve the Target Architecture. The GAP analysis is performed by verifying the Architecture samples of an internal accuracy and consistency, performing the Tradeoff analysis, checking the objectives, constraints and principles of models, Measure the changes present at the viewpoint, testing the Architecture samples (SIMON, 2016).
Cost benefits analysis for the enterprise architecture
EA is tightly tied by enhancing the exact medium finally to the execution which is undertaking. So that the important stage is mainly to describe the boundary of attempt that is being mentioned to. It is which might be whatever and is from change program to entire multi-national scheme. The succeeding stage is to mainly characterize the grade and the nature of different kind of medium period implementation change that is required. On the off chance that implementation of the venture will then be adequate in average term and point is that in the present there is no commercial or business case for the Enterprise Architecture (Reynolds, 2010).
EA is an administration rationality more than whatever else. On the off chance that senior administration holds to a logic that arranging things is superior to responding to them, they will see the advantages of EA. Since EA is the endeavor wide design, look for profits by legitimization of assets, streamlined operation, and arrangement of assets to operation and key arranging, speedier comprehension of the undertaking, normal vocabulary, acknowledgment of vision and goals.
EA without anyone else's input is a logic, yet you can do a money saving advantage investigation for EA with regards to EA particular activities. The money saving advantage would be improved the situation things, for example, administrator costs for gatherings, outline/demonstrating, and after that figured as an element of a money saving advantage investigation on foundation extends that come to fruition because of the EA adopting a logical strategy. You need to ingrain the rationality to begin with, at that point you can approach fabricating the framework, else you get an indistinguishable wreckage from you had some time recently. The imperative thing isn't to take a gander at EA as an undertaking, but instead a driver of activities with regular interest over the association (WHELAN, 2016).
EA is a circuitous incentive similarly that a vital arranging bunch is and accordingly any ROI or Cost/Benefit examination is greatly troublesome. Design helps in the change from methodology to plan and goes about as confirmation of the nature of the procedure and adds to enhanced nature of the arrangement - higher probability of accomplishment, bring down danger of disappointment, prior conveyance of results. Factually, more than two third of business procedures are not effectively executed. EA adds to expanding achievement rates.
EA as sort of forthright examination would not just let you measure the effect of EA, it would likewise enable you to guide the program to drive greatest advantages the correct way. At that point by considering a few suspicions from hazard/improve lessening into NPV/probabilities approach, it ought to be conceivable to represent the expenses and advantages that may have been achievable on past activities with various ways to deal with arranging. Applying the knowledge picked up from this activity would then permit a sensible level of trust in the request of size of advantages achievable by utilizing an EA approach on future suggestions.
Conclusion
A viewpoint for the stakeholders to view the target architecture and to analyses the goals of the business along with the requirement and principles is been provided in the Archimate diagrams by using the Archimate tool with the assistance of TOGAF. The analysis of the GAP and the target architecture is been provided successfully. This project provides a clear vision about the Business Architecture starting from week 4 to week 11, it also explains the application, business and system view of the enterprise architecture. An architecture vision for the stakeholders concern is provided and the baseline business functions of the enterprise and the organization architecture is given.
