What Is Architecture?

“Fundamental concepts or properties of a system in its environment embodied in its elements, relationships, and in the principles of its design and evolution”

ISO/IEC 42010

“Fundamental concepts or properties of a system in its environment embodied in its elements, relationships, and in the principles of its design and evolution”

“Theoretically, architecture is the normative restriction of design freedom. Practically, architecture is a consistent and coherent set of design principles”

Why Practice Architecture?

Alignment -

Insight -

Quality -

7

Architecture aligns strategy to operations and business demand to IT supply, ensuring that changes are in line with strategy and goals

Architecture improves the quality of individual solutions, simplifying their development and maintenance en prolonging their life time

Architecture provides insight into the current and desired state of the organization, information systems and technology

Enterprise Architecture

Introducing TOGAF®

11



What is TOGAF®?

• Framework for Enterprise Architecture (EA)• Originally developed by the US government in

the 80s, now owned by the Open Group• De facto EA standard in the market• A description of processes, techniques and

products for EA• A generic framework that can be tailored to

the situation

12



TOGAF Overview

13



The Architecture Development Method

• The core of TOGAF

• A proven way of developing an architecture

• Specifically designed to address business requirements

• An iterative method

• A set of architecture views to ensure that a complex set of requirements are adequately addressed

14

Service Management

TOGAF® & ITIL®

17



What Is ITIL?

• Information Technology Infrastructure Library• Framework for IT service management• Owned by the UK government (OGC)• Meant to provide guidance to service providers

on the provision of quality IT services• 26 processes, organized into 5 core books

18



ITIL Processes

Service Operation

• Strategy Management

• Service Portfolio Management

• Financial Management of IT Services

• Demand Management

• Business relationship management

• Design coordination• Service Catalogue• Service level

• Release and deployment management

• Service validation and testing

• Change evaluation• Knowledge

How ITIL Relates To TOGAF

ITIL can be seen as an architecture for IT service management

Both frameworks provide guidance for designTOGAF describes design at an enterprise architecture levelITIL describes design at a solution (architecture) level

An architecture developed with TOGAF requires input from as well as provides input for ITIL processes

The repositories that support ITIL and TOGAF are related and should build upon each other

Governance

TOGAF® & COBIT®

25



What is COBIT?

• Framework for governance and management of enterprise IT (COBIT 5)– Meeting stakeholder needs

– Covering the Enterprise End-to-End

– Separating Governance From Management

• Umbrella framework• Description of all IT-processes• Driven by enterprise goals, and the IT-goals derived

from that• Supported by extensive implementation guidance• Owned by ISACA

26



COBIT Process Reference Model

27



How COBIT Relates To TOGAF

COBIT covers most of the activities of TOGAFDescribes them only at a high level

Provides a slightly different view on activities and deliverables

Covers only the IT-perspective; enterprise architecture also includes the business perspective

COBIT adds information to the TOGAF activitiesRelates them to generic IT-related goals and accompanying metrics

Adds architecture-specific process goals and accompanying metrics

Adds responsibilities for TOGAF activities in the form of a RACI Chart

COBIT puts TOGAF into context by relating architecture processes to all other IT-processes

Project Management

TOGAF® & PMBOK®

34



What Is PMBOK?

• Project Management Body of Knowledge• A set of terminology and guidelines for project

management• The Guide to the Project Management Body of

Knowledge contains a subset that is generally recognized as a good practice

• Describes inputs, inputs, tools and techniques • Owned by the Project Management Institute• Grouped into 5 process groups and 9 knowledge areas

35



PMBOK processes

36



How PMBOK Relates To TOGAF

Both frameworks provide activities, practices and deliverables for project management

PMBOK can be used to manage an architecture projectTOGAF can be used as a lightweight project management framework (not recommeded)

An architecture constructed with TOGAF should drive the definition of a project

Provides essential requirements to projectsProvides a scope to the project, expressed using models that are part of the architecture

Project deliverables should be checked for compliance with architectures that are constructed by TOGAF

Architecture Leads To Projects

Typical contents of an Implementation and Migration Plan are:•Implementation and Migration Strategy•Project and portfolio breakdown of implementation:

– Allocation of work packages to project and portfolio– Capabilities delivered by projects– Milestones and timing– Work breakdown structure– May include impact on existing portfolio, program, and projects

•Project charters (optional):– Included work packages– Business value– Risk, issues, assumptions, dependencies– Resource requirements and costs– Benefits of migration, determined (including mapping to business requirements)– Estimated costs of migration options
