Master Plan and Notional Target Architecture

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
Many EA approaches use concept of operation drawing to communicate with business community.
Concept of operation is creative and flexible illustration of business operation.
Leverage on C4ISR OV-1 High Level Operational Concept Graphic.

Business function diagram
The notional architecture conduct high level business function decomposition.
The example drawing shows business function diagram the business function in tree structure.

The Business organization
The organization type.
The organization structure.
The organization internal logical node connectivity.
The external node connectivity.
Business reorganization
Similar to C4ISR OV-4 Organizational Relationships Chart

The Business locations
The location types.
The location structure.
The organization distribution.
The location connectivity.
Business location consolidation.
Similar to C4ISR OV-4 Organizational Relationships Chart

Notional Application Architecture
The notional application architecture
Enterprise Application concepts.
The business process/application components spread sheets.
Application system catalog spread sheets.
Application system interface diagram.

Process/ Application matrix
The process/application matrix in spread sheet describe the relation between business process and application components.

The Notional Data Architecture
The notional data architecture describe how business utilize information.
The business/information matrix in create, read, update and delete
The conceptual data subject area.
The high level data entities.

Enterprse Data Architecture
LEA practice to design the business architecture drawing set.
Information description
Information concept.
Information flow
Information entity relation.

The enterprise subject area modeling
Prepare the Subject Area Model. It identifies the organization’s high-level business
key business entities,
key relationships between the business entities,
key business entity to key business process relationships (i.e., map).

Process/data matrix
The process/date matrix in spread sheet describe the high level relation between business process and data.
It is also know as the CRUD matrix to show Create, Read, Update.

Human Resource Enterprise Architecture
Human Resources EA aligns human resource to business architecture.
The human resource EA model consist of the following layers:
Knowledge
Ability
Skills.
Business Skills knowledge Abilities

Financial Enterprise Archtiecture
Align financial resources to business architecture.
The financial Enterprise Architecture model consist of the following layers.
Financial knowledge
Financial execution.
Financial technologies.
Business Financial execution Financial Information Financial Skills

Apply architecture principle not only to IT but also to human resources and financial.
Mater plan and notional architecture in vertical architecture theory.
It is a matter of how to take advantage of technology rather than how to design the technology.
Master plan and notional architecture is the long term guide line rather the enterprise solution architecture blueprint.
Master plan and notional architecture is flexible based on need.
