Implementing Enterprise Architectures

If We Build It, Will They Come?

user compliance depends upon resolving four key issues
User compliance depends upon resolving four key issues:
  • Which standards are chosen and why?
  • What governance model best builds user support?
  • What benefits will the architecture deliver, to whom and when?
  • Which implementation strategies will grow user compliance?
enterprise architectures originated in the move to open systems and client server in the 1990s

Centralized

Hierarchical

Distributed

Heterogeneous

Enterprise architectures originated in the move to Open Systems and Client/Server in the 1990s
  • The mainframe management paradigm broke
  • The result: two of the most challenging IT management issues today:
    • The management of technological (and business process) complexity
    • The shared management of IT resources
architectures and standards reduce complexity
Architectures and Standards Reduce Complexity
  • Complexity is an enterprise problem, not a user problem
the choice of a standard is a tradeoff between granularity and workability
The choice of a standard is a tradeoff between “granularity” and “workability”
  • What is a standard?
  • Is a standard a “product”?
  • Does the standard need to be one “thing”?
  • How and when will the standard evolve?
standards provide strategic direction over time
Standards provide strategic direction over time

What Does the Standard Do?

  • Provides identity management services (e.g., authentication, authorization, personalization, certificate handling and other application development services) and central administration of IT assets.

Why is a Standard Needed?

  • To consolidate 3 current Directory Services products to one and to develop a full-function, common infrastructure for use by application developers. To comply with corporate standards effective June 2007.

What Should Users Do:

  • The strategic direction for Directory Services is MS Active Directory.
  • Novell E-directory and Lotus Domino will be stabilized, with no further enhancements. These products will be repaired as needed.
  • MS Active Directory will be operational during 1QFY07. Existing HQ server migration will be piloted in 1QFY07 with data migration completed by 3QFY07. Field office migration will be piloted 1QFY07 and completed by 4QFY07. Data migration from Novell to Active Directory will be completed by Oct 07.

What Should Users Avoid:

  • Further development using Novell E-directory or Lotus Domino.

Standard Timeline:

which standard to choose is a trade off

Economy of Scale

(Granularity)

User Compliance

(Workability)

Which standard to choose is a trade-off
  • Choose the most granular standard possible that users can and will adopt
today s enterprises have many is organizations
Today’s enterprises have many IS organizations
  • Each “owns” IT resources and functions
  • Each needs a “voice” if they are to work together to achieve a common goal
    • For many enterprises, EA is the first time they need to work together
  • Governance describes who is responsible for what and how decisions will be made
a constitution is a shared management model for peer organizations
A “constitution” is a shared management model for peer organizations
  • Preamble – the shared goals and benefits
  • Constituents – who is affected
  • Executive Responsibility –who is responsible for the architecture and standards
  • Legislative Responsibility – how will the “laws” be decided
  • Judicial Responsibility – what is the penalty for non-compliance
  • Amendments – how and when will the architecture and standards evolve
value propositions describe what benefits will be delivered to whom and when
Value propositions describe what benefits will be delivered, to whom and when
  • Enterprise architectures are developed by the enterprise, to solve enterprise problems, with the benefits accruing to the enterprise
  • For users, compliance is a trade-off between upfront costs and potential future benefits
  • Enterprise management and business unit management are different constituencies
value propositions must address the needs of each constituency
Value propositions must address the needs of each constituency
  • Enterprises want economy of scale
    • By standardizing the IT environment, complexity is reduced and consolidations become possible and support and service becomes focused
  • Business units want interconnectivity and interoperability
    • Access to enterprise resources, data quality, less rework, better support and service and lower costs
  • These are often “two sides of the same coin”
  • Two value propositions are needed, not one
value propositions must answer the wiffm question
Value propositions must answer the “WIFFM” question
  • Business Context
    • Mission (or business objectives)
    • Obstacles
    • Linkage
  • Benefits
    • Efficiency – cost and productivity
    • Effectiveness – value
  • Timing
winning implementation strategies recognize and mitigate these barriers
Winning implementation strategies recognize and mitigate these barriers
  • Seek breadth and depth
  • Focus on new investments
  • Find partners
  • Develop intercept strategies
  • Provide help
  • Market the successes
  • Compliance, like a snowball, grows over time as more and more users align with the architecture
to gain user compliance
To gain user compliance:
  • Choose standards for “workability”
  • Adopt a “shared management” governance model
  • Develop two value propositions
  • Develop implementation strategies that mitigate user constraints
  • Expect compliance over time
  • Develop and market the benefits “story”
