Certified Enterprise Architect Professional (CEAP) - Module 1 - Introduction to Enterprise Architecture

Introduction to Enterprise Architecture:

Enterprise:

 An enterprise is a large-scale organization engaged in commercial activities, often involving a complex network of operations, departments, and divisions.

Example: Corporates, components of corporations, and government agencies.

Architecture:

Architecture refers to the central organisation of a  system, the incorporation of its elements, the association of such elements with each other and the environment, and the principles leading the system’s design and development.

Enterprise Architecture (EA):

EA serves as a blueprint for the organisation's IT infrastructure and business processes, enabling alignment between business strategies and IT capabilities.

A strategic approach to architecture that addresses an entire enterprise to address below:

1. Alignment of IT with Business Goals

2. Integration and Standardization

3. Risk Management

4. Change Management

5. IT Governance

6. Business Agility

7. Response to change

8. Reliability

9. Security

10. Continuous Improvement of process

Components of EA:

Business Architecture: Defines the organisation's business strategy, goals, processes, and organisational structure. It identifies key business functions, capabilities, and workflows necessary to achieve strategic objectives.

Information Architecture: Focuses on managing the organisation's data assets, including databases, data warehouses, and data flows. It ensures that data is accurate, consistent, secure, and accessible to support business operations and decision-making.

Application Architecture: Deals with the design and integration of software applications within the organisation. It includes selecting appropriate software solutions, defining standards for development and integration, and managing application portfolios.

Technology Architecture: Encompasses the hardware, software, networking, and infrastructure components that support the organisation's IT environment. It involves designing scalable and resilient technology platforms, defining technical standards, and ensuring interoperability among different systems.

Enterprise Architecture Frameworks

Several frameworks exist to guide the development and implementation of Enterprise Architecture, such as TOGAF (The Open Group Architecture Framework), Zachman Framework, and Federal Enterprise Architecture Framework (FEAF). These frameworks provide methodologies, best practices, and standardised approaches for creating and managing EA artifacts.

Certified Enterprise Architect Professional (CEAP) - Module 5 - Architecture Frameworks

Architecture Frameworks: An Architecture Framework is a theoretical structure that has the purpose of developing, executing, and maintaining an Enterprise Architecture. Advantages of EA framework: Simplify Breaks down areas of the business process Organise business components and create and identify relationships between business Determine the scope Customization in the existing framework Disadvantages of EA framework: Need to follow process Provides only direction and not information It's based on goal and objective Need creativity and proactive thinking Zachman Framework: The Zachman Framework is a widely used model in Enterprise Architecture (EA) that provides a structured way to classify and organize an organization's information infrastructure by defining different perspectives from various stakeholders, allowing for a holistic view of the enterprise and facilitating alignment between business needs and technology solutions; essentially acting as a template to organize arc...

Scaled Agile Framework (SAFe)

The Scaled Agile Framework (SAFe) is a set of organizational and workflow patterns for implementing agile practices at an enterprise scale. The framework is a body of knowledge that includes structured guidance on roles and responsibilities, how to plan and manage the work, and values to uphold. Scrum is a simple, flexible approach to adopting Agile that's great for small teams. SAFe is an enterprise-wide Agile framework designed to help bring Agile beyond the team and into the company as a whole. Scaled Agile has built a comprehensive level that includes all the four layers called the team, program, large solutions, and portfolio level. 4 Layers: Portfolio - Strategy, Vision, Roadmap, Strategy goal, Decision making, Budget, Portfolio level metrics,  Program - Align multiple teams towards a common mission, Bring together all the Agile teams, transparency, collaboration, and synchronisation, Scrum of Scrums, Product Owners to define the overall vision. Large Solutions - ar...

Certified Enterprise Architect Professional (CEAP) - Module 4 - Architecture Precursors

 Architecture Precursors: Precursors to modern Enterprise Architecture (EA) include early frameworks like IBM's Business Systems Planning (BSP), which focused on aligning business strategy with information systems, as well as other Information Systems (IS) architecture methodologies that emerged in the 1970s and 80s, emphasizing the connection between business processes and IT systems, laying the groundwork for the holistic view of an organization that EA represents today; the "Master Plan for Information Systems" by Evans and Hague is also considered a foundational concept in this area. Drivers: internal / external pressure enforce to change the system Aims & Directives: Aims:  Goals Objectives Requirements Directives: Principles (example: Principles can be associated with business, data, applications, infrastructure, or security) Policies (example: Members of the public have minimal access to data) Business Rules (example: A rule directs and restricts a procedure)
