3 PurposeThis presentation focuses on delivering rapid assessments of the enterprise architecture capability of an enterprise. It works from the following basis:The EA framework selected is TOGAFTMThe assessment gauges the following:The readiness of the enterprise to deliver EAThe maturity of any existing EA artefacts and processes within the enterpriseThe suitability and integration points with other crucial enterprise functions such as the project office, operations management and risk managementThe assessment is based on industry best practices as well as innovative and pragmatic new methods for delivering the best value to money EA effort.
4 What is Enterprise Architecture? What is an Enterprise?TOGAF says: “A collection of organizations that has a common set of goals such as a Government agency or entire corporation, division of a corporation or single department or geographically distributed organizations under common ownership”What is Architecture?TOGAF says: “A formal description of a system, or a detailed plan of the system at component level to guide its implementation.”OfficiallyAn enterprise paraphrased according to the Oxford English Dictionary is one or more individuals that strive for a common goal.An architecture according to the Oxford English Dictionary is the art or practice of designing and constructing buildings or the conceptual structure and logical organisation of a computer system.The common theme then comes to that enterprise architecture is the practice of designing and constructing enterprise systems. The changing industry point of view is that this is not restricted to enterprise computers systems.
5 What is TOGAFTM?TOGAFTM is a framework for the design and implementation of an enterprise architectureTOGAFTM helps an enterprise design, evaluate, and build the right architectureKey to TOGAFTM is the Architecture Development Method (ADM) which is shown on the right.TOGAFTM ensures effective design and procurement specifications that facilitate open systems implementationEnable benefits of open systems to accrue with reduced riskA key to the TOGAFTM method are building blocks, explained on the next slide.
6 What are Building Blocks? A building block is defined by TOGAFTM as a package of functionality defined to meet business needs. Often the words “component”, “artefact” or “object” can be used to describe a building block.Building blocks should be seen in the wider scope of a defined and bound object or component which must have the following:Defined contents and boundariesInterfacesMetricsIn architecture, building blocks represent systems and represent the components used to build systems.In conducting architecture, the architecture itself and the framework that it is governed by are also represented as building blocks. For instance, a process, principle or policy would be seen as a building block.Most building blocks interoperate with other building blocksBuilding blocks are a useful concept not only from an architectural point of view but also from an implementation and governance point of view.Building block should have metrics associated with them in both the Enterprise and the Solutions ContinuumsBuilding blocks are found in all four of the architecture domains that are shown on the next slide
7 What are the Architecture Domains? Business ArchitectureDefines business strategy, governance, organization, and key business processesData ArchitectureDescribes structure of logical and physical data assets and data management resourcesApplication ArchitectureProvides a blueprint for individual application systems to be deployed, interactions with one another, and relationships to core business processesTechnology ArchitectureDescribes physical software and hardware capabilities required to support deployment of business, data, and application servicesSecurity ArchitectureDefines security considerations throughout the entire enterprise and across all domains. In most cases this domain is considered a cross domain function rather than a separate domain.
9 MethodThe method used to conduct the assessment has the following foundation:A industry standard EA framework is utilised, in this case TOGAFTM is chosenSets of required deliverables are discovered and distilled into cohesive components (in the TOGAFTM case, building blocks)Through integration with other frameworks and crucial enterprise functions such as programme and operations management these building blocks are rationalised into a single setThus the architecture becomes part of important programme management documents such as the PID (project initiation document)Chosen metrics are then applied to the building blocks to ensure their suitabilityThus each architecture building block can be tracked according to its maturity or cost/benefit or key risk indicatorsExisting building blocks are identified and the capability to deliver the required building blocks is examinedA gap analysis is conductedA plan and report are generated, enabling the EA effort to move forward
10 DeliverablesThe deliverables (building blocks) that are examined through this assessment are based on the TOGAFTM frameworkThey are then expanded, examined and then rationalised using other industry frameworks depending on the specific enterprise. Examples of these frameworks could include PRINCE2, ITIL and COBIT.Metrics are used to gauge the deliverables, enabling proper management of EAArchitecture assets (building blocks) are expensive to develop and maintain and through providing metrics we can assess on an ongoing basis both the value of having those building blocks as well as having an architecture for them.Recommendations are made on repositories for deliverables and processes surrounding the lifecycle of those deliverablesRepositories are logical, structured storage for architecture. They enable us to trace and analyse the very complex structures that enterprise architecture creates as well as enabling efficient maintenance
11 ProcessThis is not a linear process but rather a set of steps with predecessors.A number of these activities will take place in parallelThis process is designed to fit with the TOGAF ADM as well as industry standard architecture development processesSelect frameworkSlide 12Define EA deliverablesSlides 12 to14Examine other framework deliverablesSlides 12, 14Integrate and rationaliseSlides 13, 14Apply metricsSlide 13Analyse existing deliverablesSide 14Explore capability for new deliverablesSlides 14, 15Conduct gap analysisSlide 15Generate report and plan to deliver EA
12 Other Functions and Frameworks Other frameworks and functions within the enterprise cannot be ignored during the assessmentThe programme office form a vital component within the EA lifecycle and must be fully integrated into the process and must buy-in to the requirements for the EA deliverablesOperations management deliver the real world benefits of EA through operating the assets and capabilities designed through architecture. Operations management are also responsible for delivering key information that feeds back into the EA lifecycle to sustain it.Risk management must input into the types of deliverables that are required to enable pragmatic and successful risk managementGovernance must be integrated into the EA effort from two points of view:Outward – architecture forms part of implementation and operations governanceInward – architecture frameworks, processes and deliverables must be governed externally to the architecture effort
13 Rationalise and Measure Deliver of a rationalised set of deliverables enable all functions to understand the enterprise wide scope of EA, while creating a highly supportive environment for EAThis focuses on the delivery of assets such as integrated project architecture and project documents as well as living architecture building blocks being used in operational managementImportant metrics are applied to the deliverables ensuring (examples are provided in brackets):The deliverable value is understood (cost/benefit)The current and future requirements (maturity, completeness)The current and future state (life-cycle and relevance)The current and future integration with other functions (compliance)Business based metrics such as CSF, KPI and KRI are utilised to ensure that business understanding and appreciation of the architecture deliverables are achieved.Mature and industry standard frameworks such as COBIT are utilised to ensure completeness of the exercise
14 Existing AssetsExisting EA deliverables are examined for their applicability and measured according to the previous steps. This ensures that any deliverables that are brought forward are done on a cost/benefit and risk mitigation basisExisting repositories of assets that may exist such as programme office libraries, operations management CMDBs (Change Management Database) and KDBs (Knowledge Database) are examined for integration and existing asset valuesExisting functions are examined for process and deliverables that will support the EA effort.This step is important in facilitating the creation of the most efficient EA effort possible.
15 Analyse and ReportA gap analysis will reveal the required EA deliverables to drive the selected effort forwards as well as highlight any requirements for ongoing effort and capability creationThis effort focuses on the delivery of significant details with the TOGAF phases highlighted on the rightThe reports are distilled into practical business focused presentations with clear and cohesive action plans
