Section 3.6.3 on folio 35, provides a specific ambience for the agreement “architecture” and “system” which is able-bodied accumbent with ISO/IEC 42010:2007 analogue acclimated by TOGAF 9.
”Architecture” is authentic as:
“The axiological alignment of a system, embodied in its components, their relationships to anniversary added and to the environment, and the attempt allegorical its architectonics and evolution.”

In ITIL V3, IT behavior and strategies are authentic by chief administration during the Account Strategy appearance of the account lifecycle. These behavior may be additionally be reused during the Preliminary Appearance of TOGAF 9. The Preliminary Appearance allows us to authorize the business context, adapt TOGAF, ascertain architectonics principles, and authorize the babyminding structure. Architectural Attempt are accepted rules and guidelines that abutment the way in which an alignment sets about accomplishing its mission. These attempt should be the antecedent for the conception of IT policies.
Service Architects and Designers will charge to accede several assets such as (budgets, infrastructures, applications, information, and people) and capabilities (management, organization, processes, knowledge, and people) of the alignment authentic by TOGAF 9. This will accept to be accommodating with the business requirements which may accept been calm from a Business Scenario (TOGAF). Using inputs from the business and Account Strategy in ITIL V3, the architectonics needs to booty into consideration, people, processes, products, and partners. Additionally designers will accept to booty into consideration, the vision, mission, goals, and objectives in adjustment to construe them into analytical success factors, key achievement indicators, metrics and measurements.
Documents in ITIL V3 may be advised as actuality artifacts in TOGAF 9. Artifacts abide of plans, affairs (Architecture affairs or added forms of contracts), job descriptions, authoritative structures, action workflows, procedures, instructions, configuration, diagrams, catalogs, lists, and databases amid abounding added certificate types.
One of the above difficulties for the artist will be to array through this affidavit and aish that which is obsolete, duplicated, incomplete, or erroneous. TOGAF with its Architectonics athenaeum may additionally advice to abundance abstracts accompanying to IT Account Management. You may additionally anticipate of accumulation a CMDB with an Architectonics Repository…but that would be addition affair to discuss.
Although affairs should be advised as documents, it is important to analyze and analyze through the myriads of affairs that are in use in the organization.

Some aspects may not be covered by architectonics domains such the Ambiance (heat, ventilation, AC, etc.), or the concrete workspace including assurance (this would be covered by Security Architectonics advised during the ADM phases).
Services would be a aggregate of the four domains.
The Account Architectonics activities and processes covers:
These processes can be advised back architectonics the Technology Architectonics with the Technical Reference Model (TRM).
Page 37 of the Account Architectonics book refers to abounding accurate practices accessible for designing, deploying, and operating account architecture. It lists Enterprise Architectonics frameworks, one of them actuality TOGAF!
