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.
