What is Enterprise Continuum?
a tool for categorizing architectural source material — both the contents of the organization’s own Architecture Repository, and the set of relevant, available reference models in the industry.
The practical implementation of the Enterpr ise Continuum will typically take the form of an ______ _________.
Architecture Repository
The architect would seek to re-use as much as possible from the ____ _________ that was relevant to the project at hand.
Architecture Repository
Architecture development is a _____________, and _____________ ___________
continuous, cyclical process
Architecture Development Cycle
Key Points
1. The ADM is iterative, iterative decision making
2. These decisions should be based on a practical assessment of resource and competence
availability
3. As a generic method, the ADM is intended to be used by enter prises in a wide var iety of
different geographies and applied in different ver tical sectors/industry types
ADM Basic Structure?
1. Preliminary

[Requirements Management]
2. Architectural Vision
3. Business Architecture
4. Information Systems Architecture
5. Technology Architecture
6. Opportunities and Solutions
7. Migration Planning
8. Implementation and Govenance
9. Architect Change Management
What is the ADM?
The ADM is a generic method for architecture development, which is designed to deal with most system and organizational requirements.
What is an an ‘‘enterprise-specific’’ ADM.?
the tasks before applying the ADM is to review its components for applicability, and then tailor them as appropriate to the circumstances of the individual enterpr ise.
Compliance with the ADM is fundamental to the ________ of the architecture, to ensure that all considerations are made and all required deliverables are produced.
governance
The major infor mation areas managed by a gover nance repositor y should contain the following types of information:
1. Reference Data
2. Process Status:
3. Audit Information:
Scoping the Architecture
There are many reasons to constrain (or restrict) the scope of the architectural activity to be under taken, most of which relate to limits in:
1. The organizational authority of the team producing the architecture
2. The objectives and stakeholder concerns to be addressed within the architecture
3. The availability of people, finance, and other resources
Four dimensions are typically used in order to define and limit the scope of an architecture:
1. Enterprise Scope or Focus:
2. Architecture Domains:
3. Vertical Scope or Level of Detail:
4. Time Period:
What is Enterprise Scope or Focus?
What is the full extent of the enterprise, and how much of that extent should the architecting effort focus on?
What is Architecture Domains?
A complete enterpr ise architecture description should contain all four architecture domains (business, data, application, technology)
What is Vertical Scope or Level of Detail?
To what level of detail should the architecting effort go? How much architecture is ‘‘enough’’? What is the appropriate demarcation between the architecture effort?
What is Time Period?
What is the time period that needs to be articulated for the Architecture Vision, and does it make sense?
What are the objectives of the Preliminary phase?
1. To review the organizational context for conducting enterpr ise architecture
2. To identify the sponsor stakeholder(s) and other major stakeholders impacted by the business directive to create an enterpr ise architecture
What are the objectives of the Preliminary phase?
3. To ensure that everyone who will be involved in, or benefit from, this approach is committed to the success of the architectural process
4. To enable the architecture sponsor to create requirements for work across the affected business areas
What are the objectives of the Preliminary phase?
5. To identify and scope the elements of the enterpr ise organizations
6. To define the ‘‘architecture footpr int’’ for the organization
What are the objectives of the Preliminary phase?
7. To define the framework and detailed methodologies that are going to be used to develop enter prise architectures
8. To confirm a gover nance and support framework that will provide business process and resources for architecture governance
What are the objectives of the Preliminary phase?
9. To select and implement supporting tools and other infrastructure to support the architecture activity
10. To define the architecture principles that will for m par t of the constraints on any architecture work
