TOGAF Origins
A customer initiative
A framework, not an architecture
A framework for developing architectures to meet different business needs
Not a “one-size-fits-all” architecture
Originally based on TAFIM (U.S. DoD)

Proof of application
Relevance to practical architectures (building blocks)
Enterprise Continuum (TOGAF in context)
Business Scenarios (architecture requirements)
Architecture views - IEEE 1471
Architecture Principles; Compliance Reviews
Extension to Enterprise Architecture
Brief review of development to date:
2H94 requirement - demonstrated real need
hand-picked group of customer & vendor experts (Architecture Task Force)
first version of Framework published Dec 95, as X/Open A/F
deficiencies, but demonstrated proof of concept
many had doubted feasibility of a consensus arch f/w
Arch Task Force continued, embraced work of OSF community
second version published as TOGAF, builds on XAF, integrates arch. work of OSF community => stable, robust f/w
case studies of TOGAF used in significant projects for design and procurement of open system solution
vendor commitments to develop mappings to TOGAF from own product architectures
NCR / OCCA there already, IBM / Open Blueprint committed, discussions ongoing with other vendors
Next logical progression - build critical mass
greater relevance to specific architectural implementations
address key deficiencies

TOGAF Scope
TOGAF covers the development of four related types of architecture:
Business architecture
Data or information architecture
Application architecture
Technology architecture

7. TOGAF Version 8 (“Enterprise Edition”)
An effective, industry standard framework and method for enterprise architecture.
Complementary to, not competing with, other enterprise frameworks
Use in conjunction with frameworks having defined deliverables more specific to particular sectors.
“Demystifies” architecture development
Emphasizes business goals as architecture drivers
A framework and method for achieving the “Boundaryless Information Flow” vision

TOGAF ADM Overview
An open, industry consensus method for IT architecture
Developing an organization-specific architecture to address business needs
Architecture views to ensure that complex requirements are adequately addressed
Practical, experience based guidance
Adaptable to specific needs of a project
This is an extract from the TOGAF 5 definition on the OG Web site. This underlines what I have already said, but expands on the process of defining the Target Architecture. There are some things to note:-
The TA is based firmly on business requirements - these come into play at (2) - Views - and (5) - Confirm Business Objectives.
The “Gap Analysis” (8) looks at business needs which are not met by the TA defined in (7), and determines how the TA needs to be added to in order to meet them.
It is not clear from the way Stage C is expressed that the output is the TA, as defined in (7) and refined in (8).

A Architecture Vision
H Architecture Change Management
G Implementation Governance
C Information System Architectures
Requirements
B Business Architecture
E Opportunities and Solutions
F Migration Planning
Prelim: Framework and Principles
D Technology Architecture
An iterative method
Each iteration = new decisions:
Enterprise coverage
Level of detail
Time horizon
Architecture asset re-use:
previous ADM iterations
other frameworks, system models, industry models,…)
Decisions based on:
Competence / resource availability
Value accruing to the enterprise.

12. Foundation Architecture: Standards Information Base (SIB)
20 September 2018
Foundation Architecture: Standards Information Base (SIB)
A database of open industry standards
The complete set of Open Group endorsed standards
Content determined by Open Group consensus process
Structured according to TOGAF Technical Reference Model taxonomy
Available for public web access
Gateway to many linked resources
The SIB lists all the standards and specifications recommended by The Open Group for use in open systems architectures.These comprise the current X/Open CAE Specifications, and relevant International standards adopted by The Open Group as having the same status as CAE Specifications. It also lists all the current X/Open branding definitions.
The tables are structured according to the service areas in the TRM and its taxonomy:
Data Interchange Services
Data Management Services
Distributed Computing Services
Graphics Services
Network Services
Object Management Services
Operating System Services
Software Engineering Services
Transaction Processing Services
User Interface Services
Internationalization Services
Security Services
System Management Services
There are hyperlinks from most entries in the SIB to details of the referenced specification or standard, held either on The Open Group web server (in the case of CAE Specs and branding definitions) or the web sites of other standards organizations (ISO, IETF, IEEE).

Not to complicate things, but there are further detailed views that need be exposed and models such as this one provide a little more detail that the level 1 diagram. This is the diagram that needs to be fully populated with the right things. Right now this is just been populated for demonstration purposes where it shows the level of detail we need to get to.
