Study Notes

Enterprise Architecture Patterns and Anti-patterns

Enterprise Architecture Patterns (EAPs) are reusable design solutions for common architectural problems
They help avoid repeating past mistakes
EAPs have a consistent structure, starting with a descriptive name and problem definition
Examples include layered and client-server patterns

The Pattern Catalog

Categorizes patterns into Business, Infrastructure, and Support
Patterns within each category can use or provide interfaces to other patterns
O-shaped connectors represent provided interfaces and U-shaped connectors represent usage of an interface

Types of Patterns

Business Patterns: Directly related to core business processes, use depends on specific industry (e.g., finance, healthcare)
Support Patterns: Related to typical support functions, including human resources, finance, and logistics
Infrastructure Patterns: Provide essential, often invisible services for all patterns, crucial for effective operation

Enterprise Architecture Pattern (EAP) Example

Visual diagram illustrating a client-server architecture with components (e.g., client, server, broker, models) and interactions
Layer structure is depicted with various components within those layers

Single Sign-On (SSO) Example

SSO is an access control method for multiple software systems
Users can access the entire system with a single ID, provided over an IP network
Diagram shows interconnected systems (e.g., business applications, portals, workflow engines) using SSO

Web and EJB Operations Example

Diagram describes general operation process of web and EJB elements
Web elements depend on database resources and notice management interacts with numerous related databases

Anti-patterns

Anti-patterns are flawed solutions to common problems, potentially making the situation worse
Examples include:
- Donkey in a tiger skin: implementing an EA initiative without relevant groundwork
- Zealotry: excessive focus on theoretical EA over practical implementation
- Process without people: creating processes without considering responsible parties
- Non-political: ignoring organizational politics during program creation

Dell IT Transformation

Dell, a major computer manufacturer, broadened into IT services
Rhonda Gass leads IT strategy, using a three-year roadmap based on Enterprise Architecture (EA)
Significant investments are included in the roadmap across numerous programs (Global Quote to Cash, Global Service Delivery, etc.)

Creeping Diversity Problem

Dell's expansion into software involved acquiring companies with diverse systems
Integrating these systems created inconsistencies and difficulties
Existing systems made adaptation for new capabilities impossible; required a more focused and organized approach

Rationalization (Planning) Process

Dell's IT infrastructure rationalization focused on standardizing diverse systems
Process included understanding the current state of IT and business processes and aligning them
Enterprise vision blueprint guided projects, defining strategy, goals, and objectives

Driven by Architecture

Dell's current approach emphasizes logical, cross-domain processes, unlike prior emphasis on physical processes
Teams focus on core process areas (e.g., Develop, Market, Sell, Fulfill, Support) to enhance customer value chain

Future State Reference Architecture

Dell has created a comprehensive and detailed model/blueprint for their future state architecture.
Diagram displays visual representations of various systems (e.g., inventory, disposition applications) and their connections.

Creating Business/IT Alignment

Dell aligns IT investments with reference architecture prioritizing highest return
Architecture review boards ensure consistent implementation and adherence to established standards
Periodic review ensures projects are on track toward a three-year reference architecture goal

Process Center of Excellence (COE)

COE emphasizes process-driven approach to transformation
Focuses on key areas for development, market, sell, fulfill, and support across an organization.
Includes business priorities, and interdependencies between processes.
