Introduction to Entrprise Architecture

DNA is the molecule that carries the genetic instructions for life.

Any company should have its framework that governs its implementation for all solutions, which consists of five key pillars:

-        Innovation Model: Which will be used for reforming the business and moving forward to digital ERA.

-        Digital transformation Model

-        Engineering Model: Will be in charge of governing the engineering activities, for the project.

-        Management Model: Which standard, and how will it apply to the project, like agile for example?

-        Process Improvement Model

This framework is the process guidance model for all projects that guarantees the success of the project, which includes innovation practices, digital transformation drivers, enterprise architecture practices, engineering and management standards, and incremental improvement processes during the execution of the project.

1. Set the roadmap to achieve enterprise vision using IT

2. Moving from traditional operations, to those managed by IT.

3. Critical to business survival

4. Managed integrity

5. Strategy accelerator

6. Reduce time to market

7. Optimization across enterprise

8. Support delivery of business strategy

9. Increase organization agility(reusable building blocks, reusable HR functions, reusable e-payment, reusable cloud)

10. Integrity: The Optimization and improvement comes across all the enterprise units, in all areas, infrastructure, business, solutions, business process, tools.

• What is TOGAF?

• The open group architecture framework.

• Used in 60% of top enterprises like apple, NASA, oracle and IBM 

• There are multiple frameworks like ZACHMAN, DODAF, and Gartner, TOGAF was the latest one published by 1998. 

• According to the evolution of the model, it will act as strategic enabler for the vision. 

• What is architecture?

• Formal description of system that guide information building blocks and interrelationships 

• What is enterprise?

• Enterprise is any unit, starting from the group to the level of department.

• There is strong relationship between the enterprise level and the impact of enterprise architecture.

• What is EA?

• Business logic and process organization reflected in IT and organization operational model.

• Another definition, the conceptual blue print to define structure and operation of the organization.

• The deliverables of EA is capabilities not systems, after taking the vision as an input. 

1. ADM architecture development method

2 . Architecture content framework: the database for architecture outputs

3 . Enterprise continuum tools: is the repository, contains both ABB & SBB: architecture building blocks and solution building blocks

4. TOGAF reference model

5. Architecture capability framework: represent the ability of organization , process and persons, required knowledge, resources, and assets. 

6. ADM guidelines and tools

ADM is the lifecycle of enterprise architecture, which should be followed by the architecture team.

We can briefly determine the key processes as following:

01-Priliminary Phase

02-Architecture Vision

03-Business Architecture

04-Information systems architecture

05-Technology architecture

6-Opportunitites and solutions

7-Migration Planning

8-Implementation governance

9-Architecture change management

The below diagram show the context of the architecture, and kep pillars to take place:
