Master plan and notional Target Architecture inherit the top down and vertical architecture theory from traditional architecture development method. It is the first architecture theory among the Light Enterprise Architecture concept of vertical, horizontal and circular architecture theory.



LEA takes the light approach to conduct master plan and the notional target architecture because it is futile to design a frozen blueprint in an organic enterprise.



LEA adopt the ideal of master planning comes from city planning. Master plan and notional target architecture represent the construct and the notion of enterprise target architect. However, it serve as the mean of Enterprise Architecture rather than the end. EA is not only about drawing some high level architecture drawings. It is long term guideline not only for the enterprise mechanical architecture but also used to facilitate collaboration and knowledge sharing.



It is intended for both business and engineering community. It shows how business take advantage of different resources which include not only IT but also human and financial resources. It is not intended as the guideline on how to design or create these resources. EA should not be confused as the enterprise wide solution architecture.



Master plan and notional architecture is delivered in architecture drawing sets and spread sheet for the purpose of intuitive and comprehension by the business community. The notional architecture drawing is not as rigid a the engineering blueprint, It is flexible and creative.

  • “ System implementations make business and break through process change possible and business managers should partner with IT, not the reverse. But the reality is that when there is not clear business vision driving decisions with an organization, it is often difficult for IT to decline the leadership role in Enterprise Engineering efforts.  As a result, IT is often blamed for the failure to successfully transform an organization through implementation of systems when in fact, it is the lack of strategic business vision and leadership from the outset that led to the failure to achieve desired outcomes. Thus IT managers and organizations should not accept responsibility for driving an organization transformation without understanding the accompany risks and only after failing to recruit the necessary business leadership and vision to lead the effort.” -   Susan Grovant [Grovant, 1998 ]

Master Plan and Notional Target Architecture Master Plan and Notional Target Architecture Presentation Transcript

  • LEA Master Plan & Notional Target Architecture John Chi-Zong Wu [email_address] www.liteea.com
  • Presentation Goal
    • Distinguish EA from Enterprise wide application development
    • Introduce the concept of master plan and notional architecture.
    • Adopt the master plan concept from city planning.
    • The notional architecture is a high level architecture on how business community take advantage of technology evolution.
    • The notional architecture is a top down architecture approach in vertical direction.
    • It inherit the classical EA model and frame work.
    • LEA leverage on FEA and C4ISR approach to prepare the notional architecture drawing sets in the layers of Business, Application, Data and technology .
  • The vertical alignment Architecture
    • It is the vertical architecture theory in the LEA architecture directions as shown on the following figure.
    • It is the high level Enterprise mechanical architecture to describe long term enterprise structure.
  • Why master plan and notional architecture?
    • Master plan and notional architecture is the overall guide line and long term plan.
    • It is the beginning of EA rather than the end.
    • It is fundamental to support:
      • Business community comprehension of EA.
      • The light version of Enterprise Architecture.
      • Identify the enterprise line of business.
      • The cross cutting architecture.
      • The collaboration.
      • The knowledge management.
      • Segment architecture.
  • The light version of classical EA
    • Mater plan and notional architecture is the light version of the good old EA practice.
    • Master plan: The holistic long term plan for the enterprise.
    • Notional Architecture is the high level architecture plan
    • Master plan and notional architecture is business orientated.
      • It plans how business community take advantage of technology evolution.
      • It should be intuitive and comprehensive without special architecture training.
  • Beyond IT
    • Business analyst must take business, Finance, Human and IT resources into consideration.
    • LEA use architecture principle beyond IT architecture.
    • This presentation illustrate the master plan concept from the aspect of IT.
    • IT applies to all the following area:
      • Business architecture
      • IT resources architecture.
      • Financial resources architecture
      • Human resources architecture.
  • The level of effort
    • Master plan and notional target architecture dose not require significant investment of time and resources.
    • The goal is to establish the enterprise architecture guideline and principle rather than design the enterprise wide solution architecture blueprint.
    • It is a flexible practice for business community comprehension.
    • Master plan and notional target architecture should not take longer than six months.
  • Drawing sets & spread sheets
    • Master plan and notional architecture is prepared in drawing sets and spread sheets.
    • The architecture drawing sets consist of :
      • The Business Architecture
      • The Application Architecture
      • The Data Architecture
      • The Technology Architecture
    • Enterprise Architects are trained to prepare the architecture drawings as the traditional architects do.
    • EA is analogy to city planning.
    • The enterprise master plan is adopted from popular city planning practice as shown on the figure.
    • The mater plan is a holistic and long term planning which serve as the architecture principle.
    • It out line the plan on how business take advantage of different resources.
    • It is a collaborative effort.
    Adopt Master plan from city planning
    • The enterprise master plan is prepared using the enterprise maps.
    • The enterprise maps does not only describe the as is environment but also the future environment.
    • The master plan is created on a additional layer of the enterprise map.
    • The master plan layer use different legend to indicate the master plan.
    Enterprise Map Enterprise Master plan use enterprise map
  • The Notional Target Architecture
    • Notional Target architecture elaborate the master plan.
    • The notional target architecture inherit the classical EA model and framework.
    • The notional target architecture consist of the following products
      • The business architecture
      • The Application architecture
      • The data architecture
  • The Alignment Architecture
    • Notional architecture is an alignment architecture.
    • The alignment framework orderly arrange how business takes advantage of technology evolution.
    • It is not the solution architecture to design the applications.
    • In a layman’s term, It only concerns about how to use the vehicles instead of how to build a vehicle.
    • Notional architecture have exclude the technology architecture design.
  • Leave the detail for solution architecture
    • Notional Architecture is the long term architecture plan and guide line.
    • It is not a real architecture blueprint for construction and making transition plan.
    • Segment architecture elaborate the notional architecture plan to close business performance gaps.
    • Solution architecture design the detail architecture blueprint for construction.
  • The notional architecture model
    • The notional target architecture inherit the classical EA approach at the very high level.
    • EA apply architecture principle not only on IT but also on human, financial and industrial resources.
    • Use IT to illustrate the notional architecture approach.
    • The same architecture principle applies to every area.
    Business Knowledge Skill Ability Application Human Resources IT Resources Financing Resources Information Technologies
  • The notional target architecture framework
    • Notional Target architecture elaborate the master plan.
    • The notional target architecture inherit the classical EA model and framework.
  • Recommended architecture drawings
    • LEA recommend the following diagrams in preparing the notional architecture drawing sets.
    • Many EA projects have created useful architecture drawings which serve good examples in preparing the notional target architecture.
    • The diagrams are parallel to the products define in the US DoDAF (Department of Defense Architecture Framework).
    • Although each architecture drawing appears to be a simple graphic, It is the result of architects hard work.
  • Notional Business Architecture
    • The notional business architecture
      • Concepts of operation.
      • The business function.
      • The location.
      • The organization.
    • The enterprise activities and business processes are modeled in the Enterprise master plan.
  • Concept of operation
