What is the Zachman Framework for Enterprise Architecture?
IT is similar to a building construction and has increasing level or detail as you go down
Does the Zachman Framework have different models depending on the stakeholder?
Yes.
How many levels and perspectives did the initial Zachman modle of 1987 have?
5 Levels and 3 perspectives
What was added to the initial Zachman Framework?
- 3 new perspectives (6 in tital)
- a meta-model for the owner’s, designer’s and builder’s level
- defines 7 rules for the concretion of the framework
What are the 5 levels of the Zachman Framework?
- Scope description (ballpark view)
- Model of the business (owner’s view)
- Model of the information system (designer’s view)
- technology model (builder’s view)
- detailed description (out-of-context view)
What are the 6 perspectives of the Zachman Framework?
- Data description
- Process description
- Network description
- Persons
- Time
- Motivation
What does TOGAF stand for?
The Open Group Architecture Framework
What is the TOGAF Scope?
TOGAF emphasizes business goals as architecture drivers, and provides a repository of best practices e.g.:
- TOGAF Architecture Development Method (ADM)
What are the TOGAF long-term goals?
- an industry standard, generic enterprise architecture methods
- usable on its own or in conjuncture with product relevant frameworks
Which type of framework is TOGAF?
Business Transformation Framework.
How is capability incrementation done in TOGAF?
By the projects in the Project Portfolio and through the people, process and material dimension.
What is the structure of TOGAF organized along?
The structure and content of an Enterprise Architecture Capability
What is the TOGAF Architecture Development Method (ADM)
- an iterative method, over the whole process
- each iteration = new decision:
- enterprise coverage
- level of detail
- time horizon etc.
- decision based on: competence/ value accruing to the enterprise
What are the stages in the TOGAF (ADM)?
Preliminary
A. Architecture vision
B. Business vision
C. Information Systems Architecture
D. Technology Architecture
E. Opportunities and Solutions
F. Migration Planning
G. Implementation Governance
H. Architecture Change Management
What is the preliminary phase in ADM about?
- this phase prepares the organization for undertaking successful EA projects (undersatnding the business environment, high level management commitment, agreement on scope etc.)
What is the Architecture Vision about in ADM?
- Initiates on eiteration of the architecture process (sets scoes, contraints, expectations; required at the start of every architecture cycle)
- creates the architecture vision
- validates business context
- creates statement of architecture work
What is the Business Architecture Stage in ADM about?
- describe current business architecture
- develop target business architecture
- perform gap analysis
- define roadmap for transforming the business architecture
How does the TOGAF Architecture Content Framework look like?
On top you have the Architecture Principles, Vision and Requirements (Why questions)
What are the pros of TOGAF?
- pervasive in practice (there is a common understanding of terms)
- trainings are available
- certificates are available
- compliant tools are available
- internationally accepted
- open development
What are the cons of TOGAF?
- Inconsistencies between parts
- adaptation necessary
- learning TOGAF is not the same as mastering it
- there is a lack of concrete guidelines for the introduction of TOGAF
- there is a lean EAM countermovement to TOGAF
What is the motivation behind ArchiMate?
- precise documentation of the enterprise architecture level
- communication about architecture with others
- analysis of architecture before their implementation
What are ArchiMate’s layers and aspects?
Layers: Technology, Application, Business
Aspects: Information, Behaviour, Structure
What is ArchiMate’s generic structure?
Passive structure: objects
Behavior: Behavior elements, service
Active structure: Structure element, interface
What are recently introduced concepts in AchiMate?
- Business Goals
- Business Capabilities
- Achitecture Plateaus
- Change Programs
