MODULE 4.2 TOGAF (OPEN ARCHITECTURE FRAMEWORK)

architecture development method

may be used with other frameworks

togaf standard ver 9.2

improved guidance, improved document structure, error correction

togaf - content framework

more consistent output handling
architecture repository

major components of togaf

- architecture capability framework
- architecture development method
- architecture content framework
- enterprise continuum

architecture content framework

considers EA as CLOSELY INTERRELATED ARCHITECTURES

architecture content framework

- business architecture
- data architecture
- application architecture
- IT architecture

data architecture + application architecture

logical level

application architecture

eventually leads to IT initiatives

architecture development method decides on

- breadth of enterprise coverage
- level of detail
- time horizon
- architectural assets to be leveraged
(BLAT)

classification scheme (explicit categorizations of modules) + taxonomy

togaf lacks in ___

domain: business

strategy, governance, organization, key processes

domain: data

logical/physical data ASSETS and data MANAGEMENT

domain: application

BLUEPRINT for individual app deployment, interactions, relationships to core business processes

domain: technology

IT infrastructure; HW/SW capabilities

domain: data + application

logical

architecture development method

starts with business architecture

information systems architecture (adm)

where DATA and APPLICATION domains are dealt with

information systems architecture (adm)

where to make roadmap of initiatives

technology architecture

determines hardware and software for implementing initiatives

opportunity and solutions

comes after identifying initiatives, what can give competitive edge

togaf - modular structure

isolation of specific guidelines
incremental adoption

togaf

high level framework for enterprise software development

architecture capability framework

addresses org, processes, skills, roles, responsibilities to establish EA

architecture capability framework

everything is heavily justified, that they're ready for EA, will allocate resources, is capable

core of togaf

architecture development method and content framework

enterprise continuum

illustrates how architectures are developed across a continuum

enterprise continuum

includes:
- foundational through common systems architectures
- industry-specific architectures to an enterprise's own archi

enterprise continuum

leverages on looking at architectures on different levels

enterprise continuum

useful in long-term, not immediately (not really useful in project)

system - domain - organization - industry (sdoi)

spectrum used to note best practices that can be carried over to the next level

business architecture

conceptual level, purely business level

architecture development method

iterative - for each iteration, FRESH DECISION

architecture development method

might need customization

architecture development method

methodology, tells what to do/produce

mda

togaf can be paired with ___ if company wants to be better in software development

supported architectural domains

- business
- data
- application
- technology (bdat)

domain: technology

overlapping

architecture development method

has 8 steps that may be done simultaneously or parallel

preliminary (adm)

bypassed but takes a while to be finalized

architecture vision (adm)

how ea can be beneficial to enterprise, bypassed

business architecture (adm)

can start here esp if no business knowledge as it tells a lot about business processes, industries
--> business capability

information systems architecture (adm)

identifying IT initiatives

migration planning

how to transition from one system to another

implementation governance

deployment where rules will be followed

architecture change management

seen after system deployment

business vision and drivers
business capabilities

togaf positioned in a way that it's aligned with 2 business foundations:
