What is TOGAF?
It stands for The Open Group Architecture Framework which is a high degree design method that helps enterprise in designing enterprise structure. In simple words, it’s a framework to endeavor structural design offering a strategy for making a venture data equipment structural design.
Why should we use TOGAF?
Here are the reasons why TOGAF is very popular amongst its users:
- TOGAF is accepted and adopted by everyone in the market.
- It comes under free abstract license.
- Best Practices are included in it.

What is Enterprise Architecture?
Enterprise Architecture is a collection of information that describes a business, its technology needs. This information contains the business goals, the business process, the business role, information about system and applications.
What is an Enterprise Architecture Roadmap?
The enterprise architecture roadmap stands for company’s goals. You can say, it describes the current target architecture and a plan to reach the target state. For each state, an enterprise architecture roadmap should include business, application, and data. The enterprise architecture roadmap lists all the projects that are needed to achieve the proposed architecture goal.
What is the value of Enterprise Architecture?
Enterprise architecture is the key to understand the current investment in IT and make investment plans for future IT. Moreover, enterprise investment allows you to identify opportunities to improve key Enterprise metrics.
What is the TOGAF framework?
The Open Group Architecture Framework or TOGAF Framework is an enterprise architecture framework. The framework provides a comprehensive approach to the design, planning and implementation in enterprise architecture.
TOGAF divides the enterprise into four sections such as Business, Application, Data, and Technology. It includes a method to define IT in terms of the set of building blocks. It also provides a vocabulary for TOGAF and its compliant tools.
What are the steps involved in Architecture Development Method?
There are total nine steps in architecture development which are as follows:
- Choosing the perspectives, apparatus and orientation figures.
- Manufacturing baseline product structural design picture.
- Assembling the manufacturing structural design information.
- Acting on a crack breakdown.
- Labeling the nominee roadmap workings.
- Determination of collision the infrastructural background.
- Prescribing stakeholder analysis.
- Confirming the industrial construction.
- Planning a structural design description article.
What are the architecture domains of TOGAF?
There are total four architecture domains of TOGAF. Here are those domains:
Data architecture: The main task of this domain is to describe the structure. The structure can be an organization’s logical and physical data possessions as well as company’s related data management resources.
Application architecture: Application architecture domain creates the blueprint for each and every application. The domain helps in communicating between the request structure and the interior dealing systems.
Business architecture: The Business architecture domain helps in identifying the governance term, business strategy and key business process of the organization.
Technical architecture: The technical architecture domain helps in describing the software, hardware and network communication that help the consumption of main interior claims.
What is the Zachman Framework?
The Zachman Framework is an IBM tool that was developed in the 1980s. The Zachman Framework offers a way to define an enterprise on the basis of 6×6 matrix architecture documentation. The columns of this matrix ask some questions such as “why, how, what, who, where, when”. The columns look at these questions from different levels of detail such as contextual, conceptual, logical, physical and detailed. The Zachman Framework provides a view to the planners and designers.
How can you evaluate if a solution conforms to the Enterprise Architecture?
To make sure that the architecture compliance processes are included in the project planning, you have to engage the projects during the initiation phase. Once you are done defining the solution architecture the next step is to perform the compliance assessment. By performing the compliance assessment you make sure that the project conforms to the defined Enterprise Architecture. Also, it is an opportunity to ask the project members for their feedback about the enterprise architecture. The compliance assessment includes a checklist for different project sectors such as applications, security, hardware, software, information and so on. It also offers a document regarding the project architecture.
What is SOA?
In simple words, SOA is a set of design principles. We use the design principal for building a suite of interoperable, flexible and reusable services. The design principal includes a discoverable service contract, loose coupling, service abstraction, service reusability, service autonomy, service statelessness and service composability. By performing a successful SOA implementation can reduce IT costs as it increases the reusability. Its flexibleness also helps in reducing the market time. It also helps to leverage existing investments since SOC wraps legacy applications in a mesh of reusable services.
What is ITIL?
The ITIL stands for Information Technology Infrastructure Library. In simple words, ITIL is a set of best practices for IT service management. It is also one of the best practice in sectors like IT development and operations.
ITIL offers detailed descriptions for many IT concepts. As well it includes a checklists, tasks, and procedures that can be tailored for any enterprise.
Here are some of the major areas which ITIL covers:
- ITIL covers the service support.
- ITIL Helps in service delivery.
- It also covers the ICT Infrastructure Management.
- ITIL also provides support for Security Management.
- ITIL helps in Application Management.
- It helps in Software Asset Management.
In the support section, the ITIL covers processes like Service Desk, Incident and Problem Management, Change Management, Release, and Configuration Management.
Talking about the Service Delivery section here ITIL covers processes like Service Level Management, Capacity Management, and Service Continuity management.
What is an Architecture Vision? What information does it contain?
The Architecture Vision comes under the light during the process of project initiation for a project. The main goal of the Architecture vision is to make sure and finalize the desired outcome for the project at the very beginning of the project. It is an elevator pitch to the enterprise architect. The Architecture Vision needs to simply and powerfully convey the benefits of the proposed architecture to the decision-makers. As well the Architecture Vision needs to display a strategy that can support the business goals.
Here are some of the typical contents of an Architecture vision:
- Problem description
- Process descriptions
- Roles and actors
- IT principles
- Architecture overview
- Mapping of the proposed architecture to processes and requirements.
How can the principles be applied to the enterprise? The Principles can be applied to the enterprise by providing a framework to make conscious decisions about IT Establishing. Also, it must provide relevant evaluation criteria driving the definitions for functional requirements of the architecture. Also by providing input to assess existing IS/IT systems and future strategic portfolios. Highlight the value of the architecture specifically through the Rationale statements. It needs to provide an outline of the key tasks, resources, and potential costs specifically through the Implication statements supporting architecture governance. It should also provide a stake to allow interpretation in compliance assessments and support the decision to initiate a dispensation request. Principles need to be related to each other and are applied as a set. In some cases, one principle will take precedence over another principle to meet certain situations.
