The Enterprise Architecture team has a lifecycle of its own, but doesn’t operate in a vacuum. The Enterprise Architecture capability fails if it is seen too much as blue sky thinking in an ivory tower.

The Enterprise Architecture team will interact closely with all the other management processes in an organisation, especially the IT management processes. When all these processes work together effectively, an enterprise will be able to successfully manage strategic changes and drive business transformation effectively and efficiently. Often in organisations little thought has been given to the integration of the EA processes to the other management processes. This contributes to making the EA team into an ivory tower, seemingly unconnected with everything else. The aim of this post is to shine some light the EA lifecycle and its interactions.

One of the goals when establishing or maturing an enterprise architecture capability is to make sure that the enterprise architecture a fundamental and normal part of the business-as-usual decision making flow rather than considered as an afterthought.

Too often I have seen major changes apparently started directly at the project initiation phase before there has been any serious appraisal of the business fit, technical fit and feasibility of that change undertaken, not least by the enterprise architects.

The Enterprise Architecture capability is driven by understanding the business strategy and strategic scenarios which drive the business and IT enabled changes in an organisation. It is there to ensure that any strategic change is viable in the future, but it also identifies the dependencies, feasibility, risks, issues, costs, and informs the subsequent investment decisions that need to be made.

The current state and future state enterprise architecture models will be developed (typically using the TOGAF ADM).

In the EA roadmap, the strategic changes will be prioritised and arranged into a meaningful sequence to inform the decisions made by the programme and project portfolio management and before any projects are initiated.

The Enterprise Architecture capability will govern what parts of the future state enterprise architecture are developed and delivered by the projects, and thereafter ensure that the delivered solutions and services remain compliant with it. The compliance stage will also capture and approve any innovations that are identified as useful. The enterprise architecture team and/or a technical design authority will provide design assurance for the projects, to ensure that principles, standards, patterns, policies and guidelines are being followed.

It’s worth noting that the EA lifecycle is not a part of the project solution development lifecycle as many organisations seem to imagine it is, but is a separate lifecycle that operates in parallel at a strategic level. Neither is the EA lifecycle the same as the TOGAF Architecture Development Method.

After a solution has been delivered, the enterprise architecture team will harvest the results in order to update the current state enterprise architecture, to measure performance and to publish a dashboard for the senior management team.

The following diagram illustrates the major stages and processes that are undertaken by an Enterprise Architecture team, for each iteration they undertake.

EA lifecycle


These Enterprise Architecture processes can be best understood in the wider scope and context of all the processes defined by the COBIT5 framework for the governance and management of enterprise IT.

I’m surprised that COBIT is not used more in UK based organisations, but it is more popular in Europe. I would recommend COBIT5 is used as a broad framework for assessing the risk and value of IT and the governance of all IT management processes.

The following view is broadly based on the COBIT processes, and illustrates the position of the Enterprise Architecture processes relative to the other IT management processes identified by COBIT.

EA processes

Starting from the Strategy & Vision there is an overall clockwise cycle through all the processes. The Enterprise Architecture capability is responsible or accountable for the processes shown in red, and is consulted and informed about the other processes. The responsibilities will, of course, vary in each organisation and in many cases the enterprise architecture team will be additionally responsible with many more of the Solution Development processes (for example, Select, Acquire, and maintain COTS software products).

In a more mature enterprise Architecture environment, all these processes will be expected to consume and contribute to the knowledge, information and models held in the Enterprise Architecture repository (illustrated in the centre of the diagram). The management dashboard of performance metrics, charts and graphs will be generated from the EA repository.


The above diagram is based on the COBIT processes. The latest version of COBIT5 is more explicit about enterprise architecture than earlier versions were.  The following table shows the COBIT5 processes that directly relate to or are supported by an Enterprise Architecture team and an Enterprise Architecture Governance Board.

COBIT5 reference Process
APO03 Managing Enterprise Architecture
APO02 Define Strategy (in this context this usually means the IT strategy)
APO04 Manage Innovation (via the Enterprise Architecture Governance Board)
BAI08 Manage Knowledge (via the EA Repository)
BAI06 Manage Changes (i.e. Strategic changes and IT enabled Business changes that drive the future state enterprise architecture)
MEA03 Monitor and assess compliance with external requirements (via the Architecture Governance Board)
APO05 Manage Portfolios (with EA Roadmap)
APO011 Manage Quality (via EA Appraisals)
APO012 Manage Risk (via EA Appraisals)
EDM01 Set and Maintain Governance Framework
EDM02 Ensure Value Optimisation
EDM03 Ensure Risk Optimisation


The following table shows who is Responsible, Accountable, Informed or Consulted in regard to the services provided by the Enterprise Architecture team and an Enterprise Architecture Governance Board.


Implementing the EA lifecycle and integrating it with the IT management processes in an organisation will help the Enterprise Architecture capability to avoid the challenges and misperceptions that it is some kind of ivory tower that can be wilfully ignored and disbanded when looking for budget cuts.

Senior management teams will instead come to appreciate the valuable contribution that Enterprise Architecture makes to strategic planning, appraising investments in change, driving business transformations, finding opportunities and innovations, and to understand the value EA has to the organisation as a whole.

Outside In

24 June 2013

How often do you see customer journeys, customer events and scenarios modelled in an Enterprise Architecture model? Not often, if at all I suspect.

In my opinion, the ‘Enterprise’ in Enterprise Architecture should include all those stakeholders that are engaged with an organisation. This include all those suppliers and service providers to the left hand end of the Value Chain, and the Customers at the right hand end. In this post I’ll be focusing on the Customers that are consuming the products and business services that are the outcomes of the Value Chain.

This is the view that the Customers have from the outside of an organisation looking in. This perspective should drive what a business does.

In most organisations however, the Enterprise Architecture is usually focused on the organisations internal workings, the inside out view of how an organisation can become more efficient, leaner and reduce cost, as a way of making more profits. The focus is on delivering better software faster, improved processes, commoditised infrastructure, reusable IT services, providing a self-service internet to replace face to face contact with the customer and so on.

The business strategy may look at the customer and market segments and the drivers for strategic change, but this is often as far as it goes. The rare organisation models the customers journey and the customers perspective and if they do then its rare to find the customer journey modelled in the Enterprise Architecture.

Organisations often try to reduce the direct interaction they have with their customers by removing phone numbers from their web sites, and providing limited set of services and FAQs. Customers are forced to waste many minutes on the telephone, selecting endless options in an attempt to get a human voice to speak to. Companies are afraid of this because of the costs of complaint handling.  To be fair, a number of organisations have implemented a live chat IM service on their web sites and high value customers do often get a live account manager to speak with. But what about the rest of us everyday customers?  It still seems like businesses are  lacking a good understanding of  their customers behaviour.

Digital Businesses and Digital Customers

Every business is now a digital business. It’s the same for customers (i.e. all the consumers, customers, potential customers and contacts) who are also increasingly digital using technologies like smartphones, social networks and broadband. They are using their own devices (such as iPads and other tablets) to research potential products and business services that they wish to purchase from businesses. They browse social networks and conduct searches to determine what product or business service best suits them. They have mass access to huge networks of information such as Google to help them.

Customer behaviours are changing, but does your enterprise architecture model know that? Does it model what the customers’ own processes are? Does it model the events that originate from a customer? Does it model what the various scenarios that there are in the customer journey? In my experience the answer is typically ‘No’ to all these questions. In my experience even when an organisation is modelling the customer journey then it is never included in the future state enterprise architecture.

What is the customers’ processes? Customers will conduct a search and discovery process, engage with the business to select, negotiate and make a purchase. If the business is lucky then the customer will re-engage to make future purchases, but if they screw up the customer will get annoyed and tell all their contacts on social media about why they are no longer buying. Companies are seeing the increasing power of customers but how many are trying to understand them and model their behaviours?

Enterprise Architecture, or more specifically, the Business Architecture within the Enterprise Architecture discipline should cover the customers’ interactions with a business, understand what they are saying on social media.

An initial approach is to speak with customers and use a thinking framework such as VPECT to determine their Values, Policies, Events, Content, Trust Relationships.


They can also use the less engaged PEST analysis for strategic market research.


Results of conducting VPECT analysis and PEST analysis should be recorded in the enterprise architecture models and associated to a representation of the customers journey

How should we model the Customer Journey and the different customer scenarios?

For a start, each scenario in a customer journey will be triggered by one of more of the Events discovered by VPECT analysis and be concluded by something of Value delivered back to the customer (Content).

What does the Event trigger? For me the best representation is a sequence of Business Services, in what might be called a Service Flow diagram.

This is much the same as a Process Flow diagram but from the external perspective. For a customer interacting over the internet, the Business Services might involve a Browse Service, A Product Detail Service, A Product Price Service, A Payment Service and a Fulfilment and Delivery Service. The Outside In service flow view is later mapped to the Inside Out process flow view

Customer Journey model

Customer Journey model

It’s easy to see that an organisation may not itself directly provide all these Business Services (for example the Payment Service may be provided by PayPal or similar, and the Fulfilment service may be provided by DHL or similar)

What also need to be modelled are the Customers own goals and objectives and how the scenario of service based interactions supports the customers goals.  Key measures should also include:

  • How much did the customers have to invest in the interaction (in time, and navigating complex interfaces, breaks in the interaction, confusion) to complete it?
  • How much they enjoyed the interaction (customer satisfaction feedback)?
  • How many customers abandoned the attempt early?
  • How many customers complained to their social media contacts afterwards?
  • How many customers complained directly to the business?


Another question that needs to be addressed is what channels and multiple channels do customers use? Customer these days are much more likely to use multiple channels at different times, rather than just a single one:

  • Search the internet with their iPad or smartphone at home
  • Switch to using their desktop PC at work
  • Use the telephone, email, IM message or SMS message for clarification on product details, prices and discounts
  • Hand off the desired purchase to their purchasing department to use corporate discounts to make the actual purchase
  • Expect an email or letter with their receipt, complemented by an SMS message to their mobile device and copy to the purchaser

Channel strategies don’t often allow for a customers’ use of multiple channels and for account information being passed around during an interaction with the customer. Businesses often manage different channels with different functions and organisation units. This results in confusing and frustrating transfers between departments. How often have you called a business, given your contact and customer account details, only to be handed off to another department who asks you all over again for that same information? It’s extremely annoying and it’s this kind of symptom that undermines the customers’ experience and sends them tweeting negative remarks.

One to One marketing

One-to-one marketing refers to marketing strategies that are designed as if they apply directly to an individual customer. Information is collected about customers’ needs, customer segments that they fall into, their preferred channel, their lifetime value to the business and which products and business services they are likely to purchase.

See the books by Don Pepper and Martha Rogers: The One to One Future and the One to One Field book.

What one-to-one marketing misses is more of an Outside In perspective, going much further in understanding the values that a customer needs and their own processes that customers follow (formally or informally).

The book I recommend is ‘Outside In: The Power of Putting Customers at the Center of Your Business’ by Harley Manning, Kerry Bodine et al.

Total Unified Customer Communication

Typically organisations still tend to communicate with their customers in a disjointed and unconnected way. Invoices, statements, receipts, marketing literature, pricing deals, discounts, marketing campaigns, letters, emails, IM messages, data streams etc.. are all sent from many different departments who have no idea about the incoming or outgoing communications that have already been received or are being made by other departments. The result is customer confusion. To be fair, the situation is not so bleak for business customers, as it is for individual personal customers, but increasingly it’s difficult to tell the difference and negative social media discussion will also impact the business customers.

Instead of just silo based incoming communication with customers we need to get a total view of all the customers interactions both incoming and outgoing to the business, and within social media, centralising all interactions, via multi channels, with a Customer Communication Management (CCM) system. Curiously I’ve never seen a Customer Communication System in any future state Enterprise Architecture model and the recommendation to include one has fallen on deaf ears.  One to one marketing should become one to one multi-channel total customer communication.

Companies will want to differentiate their products and business services and to compete with other businesses and therefore they will need to innovate. Understanding their customers’ perspectives and their customer journey scenarios will be a key innovation for any business. This will require that the future target Enterprise Architecture model includes these views and connect them to the rest of the model.

As Business Capabilities are directly derived from the corporate strategic plan and are designed to satisfy the enterprise’s business strategies, goals and objectives, so they provide an excellent basis for the creation of an Enterprise Architecture Roadmap.

What are Business Capabilities?

A Business Capability represents the ability of an organisation to perform an activity that results in an outcome of value. Business Capabilities are as far as possible expressed in terms of those business outcomes and value. As far as I know the concept originated from MODAF and was later adopted by TOGAF. See

Many Enterprise Architects and organisations fail to really use them, but in fact they are slowly becoming a common EA deliverable and a way of developing a target operating model view.

The key to their increasing popularity is because the Business Capabilities are expressed in terms of business outcomes and value rather than in purely functional or IT terms (i.e. Not just in terms of business unit needs or in terms of IT Solutions) thereby ensuring IT alignment with the business. Being expressed in terms of outcomes and values also means that Business Capabilities are tied to the outside in perspective of the Customer Journey and Strategic Scenarios, rather than the inside out perspective.

A good book to read about the outside in perspective is “Outside In: The power of putting Customers at the Center of Your business” by Harley Manning et al.

In order for an organisation to perform an activity, many parts of the organisation need to be involved. Consequently a Business Capability is modelled as grouping of other EA concepts including the following:

  • People
  • Organisation Units
  • Functions
  • Processes
  • Business Services
  • Information & Data
  • Application Services
  • Applications
  • Infrastructure Services
  • Infrastructure

In this way a Business Capability can be seen as a cross cutting slice through a typical enterprise architecture model.

A Business Capability is used for managing units of strategic business change and providing the mandate for programmes and project portfolio. Subsequently, project will develop a solution that either creates a whole new Business Capability or updates a Business capability by implementing a Capability Increment.

Thus, Business Capabilities and Capability increments provide the basis for the development of the EA Roadmap.

Business Capability Model


Figure 1: Example Business Capability Model Source: UK Government Reference Architecture (UKRA) v1.0

This diagram illustrates the start point for a Business Capability Model. This is a static view based on the style of IBM’s Component Business Model. This is a style diagram that has become quite popular.

The whole matrix represents all the Business Capabilities that the organisation performs. Each cell is a Business Capability.

The Columns usually reflect the high level value chain for the organisation or are major groupings of Business Capabilities that are meaningful to the business.

The Rows reflect the fundamental purpose of a Business Capability and there are normally three rows:

Row Aligned to the Viable System Model (VSM) system type
Direct (or Strategy) System 5 and system 4
Control (or Management) System 3, system 3* and system 2
Execute (or Operate) System 1

For details about VSM, the Viable system Model see and my earlier blog posts.

Business Capabilities also have dependencies between them. I.e. one Business Capability has to exist before another Business Capability can be achieved.

Implementing Business Strategies requires new or changed Business Capabilities, but for the most cases we are just changing some aspects of the Business Capability rather than introducing brand new ones. This is the Capability Increment.

Relationship between Business Capabilities, Enterprise Architecture and projects

Figure 2: Diagram showing Business Capabilities Source: TOGAF

The diagram above shows the relationships between Business Capabilities and Capability Increments, and also related the Enterprise Architecture development method phases and definition of work packages for the Programme and Project Portfolios.

Capability Increments document the changes to each Business Capability that are needed to implement the Business or IT Strategies.

Each Business Capability is decomposed into one or more Capability Increments that are typically implemented at different points in time and in different Transition Architectures. Each Capability Increment represents a unit of change.

Capability Increments also have dependencies between them. I.e. one Capability Increment has to be implemented before another Capability Increment can be achieved.

BC and CI

Figure 3: Capability Dependency Model

The diagram above shows the dependency relationships between the Business Capabilities and between the Capability Increments.

The Capability Increments can be rearranged to show the dependency order in which they need to be applied. This sequence forms the basis for the EA Roadmap.

EA roadmap

Figure 4: EA Roadmap structure

Often it is may be useful (and politic) to represent several tracks in the EA Roadmap. For example tracks may be introduced for Strategic changes, Business changes and IT changes, since Capability increments may be identified in such a way that they can be implemented in parallel.

The Capability Increments can be grouped into Transition Architectures. A Transition Architecture is an intermediate Architecture model somewhere between the current state and the future (target) state Enterprise Architecture model being aimed for. A Transition Architecture will typically be aligned to intermediate and temporary stages in implementation.

Groups of one or more Capability Increments will provide the mandate for a solution or service to be developed in a project.

A Business Capability Model should be at the core of all Enterprise Architecture Models.

Often the Architecture Vision Model or Core Model is produced as a Business Capability Model to provide a strategic view that helps all stakeholders in an organisation to develop a common understanding of what needs to be done and what needs to be changed.

EA Voices

16 June 2013

I have recently come across a web site EA Voices (‎) produced by John Gøtze

This is described as an Aggregated Enterprise Architecture Wisdom and I have found it to be a good collection of articles and recommend it to all Enterprise Architects out there.


What is Enterprise Architecture

Enterprise Architecture is essentially a strategic planning discipline for ensuring that all the strategies of an enterprise are well executed. How should we measure it and how it is performing?

First it’s best to clearly understand what Enterprise Architecture is and who it is for.

Enterprise Architecture bridges the gap between those decision makers who come up with new strategies and objectives and those who are involved in enterprise transformation and investments in change. It is about what the enterprise can do now (baseline capabilities) and what it wants to be able to do in the future (target capabilities).

Enterprise Architecture is all about keeping an organisation robust, viable and continuing to satisfy all its stakeholders in the future, who are interested in the enterprise succeeding and continuing to succeed i.e. the CxOs, Shareholders, Customers, Partners, Suppliers etc.

The Enterprise Architecture deliverables are a conceptual blueprint or Target Operating Model that explicitly defines the mission, vision, strategies, objectives, principles, standards and business capabilities at the strategic level, as well as all the other elements (component types) in the enterprise that define how the business operates. These elements include business functions, business services, business processes, scenarios, value chains, value streams, products, application services, applications, technology and infrastructure and are defined within the following Architecture domains:

Architecture Domain Typical object types in the domain
Market/Environment Supplier, Partner, Shareholder, Stakeholder, Regulator, Customer, Contact, Prospect etc.
Strategy and Motivation Drivers, Mission, Vision, Strategy, Objective, Measure, Metrics, Principle, Standard etc.
Business Business Capabilities, Business Functions (Value Chains), Business Process, Strategic Scenarios (Value Streams), Events, Products, Business Services, Organisation Units, Persons and Roles etc.
Information Business Information, Application Data, Stored data (Databases, Files etc.)
Applications Application Services, Applications (Suites, Packages, Components etc.)
Infrastructure IT Infrastructure (Hardware, Nodes, Networks, Devices, Appliances, Servers etc.Physical Infrastructure (Buildings, Facilities, Vehicles, Machinery, etc.)

Enterprise Architecture also provides several different views of how an enterprise operates and changes, by maintaining a baseline enterprise (operating) model, target enterprise (operating) model(s) and a roadmap of changes to the enterprise’s business capabilities and investments in change ordered within an enterprise transformation roadmap.

Measures and metrics

A large number of organizations use Enterprise Architecture approach in order to plan strategic changes and manage enterprise transformations. Enterprise Architecture is not directly linked to a direct outcome but is usually indirectly related.

One of the major concerns is the failure of many enterprises to actually measure the value of their current or baseline Enterprise Architecture. One is reminded of the old adage ‘What you don’t measure, you can’t manage’. When changes occur as a result of new strategies and target enterprise models, the subsequent enterprise transformation may well be many months or years into the future. Changes are delivered by other groups inside the enterprise or external solution delivery partners. If measures and metrics are not used and actively managed then it becomes rather difficult to compare the old baseline with the new baseline to see what value has been achieved.

Identify the Metrics

The measuring metrics will vary from one enterprise to another. As Enterprise Architecture exists to support the CxOs and decision makers within the enterprise then it is important to define the metrics from their perspective.

Metrics can be identified form a number of perspectives.

Broadly these can be grouped into:

Categories Description examples
Internal (Inside Out) metrics Metrics that measure the internal efficiency of the enterprise’s functions, processes, applications, infrastructure
  • Cost of business processes
  • Business Process efficiency
  • Operating expenses
  • Productivity
External (Outside In) metrics Metrics that measure the way the enterprise operates from the perspective of those stakeholders outside the enterprise.
  • Customer Satisfaction
  • Sales per customer
  • Profits per transaction
Change related metrics Metrics that measure how well the enterprise transformations are being achieved
  • Profits per Investment in change
  • Percentage of the target EA Model that has been implemented
  • Percentage strategies realised

More detailed metrics can defined for each Architecture Domain. Here below is a discussion of some of some potential metrics used for measurement of their enterprise architecture’s value.

CxO’s Metrics

The Enterprise Architecture is by definition the architecture of the enterprise, so the metrics also need to be defined from the enterprise or business perspective. The CEO and other CxOs are responsible for managing the enterprise so the metrics need to be ones that they are interested in and keen to measure. These may include:

  • Completed transactions
  • Revenues
  • Operating expenses
  • Profit
  • Revenue per dollar of operating cost
  • Profit per completed transaction
  • Productivity
  • Profits per investment

The trends and rates of change in the numbers are often more important than the actual numbers.

If the enterprise strategies and therefore the target Enterprise Architecture are not having an effect (directly or indirectly) on the numbers that the CEO is interested in, then the Enterprise Architecture is not being effective.

Customer experience metrics

One of the biggest contributions to Enterprise success and profits is the overall customer experience and satisfaction. There are three categories of Customer experience metrics:

Category Description Examples
Descriptive Metrics About what happened when a contact, prospect or customer engages with the enterprise
  • Call and email volume
  • Average call time
  • Calls lost
  • Website visits
  • Average transaction values
  • Average calls per customer
Perception Metrics What did the contact, prospect or customer think about what happened
  • Customer satisfaction with their experience
  • Goal completion rate
  • Complaint resolution rate
Outcome Metrics What will the customer do as a result of what happened
  • Likelihood of recommending
  • Likelihood to purchase
  • Actual purchases made
  • Returning customers
  • Churn rates
  • Value provided

These metrics measures how happy a customer or prospective customer is with the enterprise’s value proposition (their products and business services). What value is provided to the customer? This measure is becoming common with value based pricing approaches. How easy is it for the customers to do business with you? Do the enterprise business services provide for the needs of the customer’s own internal processes? Customer Satisfaction can be increased by better communication with them through their preferred channel, so a measure of Customer communications (messages and interactions, social media) can be useful.

Cost Benefit

Cost/Benefit ratio to measure the value of any new or changed business capability. This is used to compares the amount of money spent on the transformation (costs) to the amount of money that is being saved after the implementation of the changes (Benefits). These metrics are often measured in terms of money, but in fact the benefits may be non-monetary values such as increased sales, improved customer satisfaction, reduction of risks, increased flexibility, and improved platform for future change.

Productivity and Effectiveness

CEOs will be concerned with the effects of Enterprise Architecture and new investments on production, efficiency and effectiveness. Metrics in this area can focus on:

  • Reducing time to market for new investments in change
  • Integrating and improving business processes across the enterprise (including with partners)
  • Improving the ability to integrate data and interfaces across the enterprise (including with external partners)
  • Improving the ability to reuse business functions, business processes and application services
  • Increasing agility, flexibility and ability to rapidly change in the event of new strategic scenarios occurring
  • Increasing standardization
  • Reducing the time taken to develop solutions by maximizing reuse of enterprise architecture models

Governance and compliance

Enterprise Architecture ensures that the strategies of the enterprise are realised.

How many business capabilities are being created, updated or removed? What capability increments are being turned into investment proposals and providing the mandates for new programmes and projects? How many capability increments are being delivered by the solutions that have been subsequently designed and developed? How well are the solutions in compliance with the target enterprise architecture model?


The Enterprise Architecture function will create a well-populated repository of knowledge about the current state of an enterprise and its planned future state vision. The enterprise Architecture models provide a knowledge base for CEOs, CxOs and other decision makers that provides answers to their questions. In essence an enterprise architecture model needs to be designed to answer all their potential questions. How well does it achieve that?

These questions can be about gaps, impacts, dependencies, probabilities of success and failure, risks, costs etc. One of the major concerns of Enterprise Architecture is to reuse the knowledge, information and data as required by various processes and applications throughout the enterprise. Metrics can include the percentage completeness of this knowledge base. How easily and readily available is this knowledge throughout the enterprise to those stakeholders who need it?

A Common Vision of the future state

The whole purpose of Enterprise Architecture is to align investments in change with the strategies for the future of the enterprise. The target Enterprise Architecture Model is the target operating model that provides a common vision for all parts of the enterprise, including internal business units and external partners. How complete is this model and all the associated diagrams and documentation? Is it readily available?

Enterprise Transformation

The target enterprise architecture model will reduce the time it takes to conduct a particular enterprise transformation, implement new and changed business capabilities and reduce solution design and delivery time and development costs by maximising reuse of the enterprise level models. It will provide standard components and ensure maximum reuse of them across the whole enterprise. Over time the enterprise architecture will ensure faster development, fewer failures and better alignment to strategic enterprise level requirements and continual improvement.


The Enterprise Architecture is often focused on improving or enabling various characteristics and qualities in the future.

Metrics can be based on these qualities can include:

  • Efficiency
  • Robustness
  • Reliability
  • Viability (ability to remain viable in a changed environment)
  • Flexibility (ability to automatically adapt when unexpected external changes occur)
  • Complexity
  • Agility (Ability to adapt to changing business needs)
  • Adaptability
  • Ease of integration
  • Amount of reuse
  • Support for innovation
  • Service level
  • Quality
  • Accuracy

In conclusion

Enterprises need to measure Enterprise Architecture by how well it improves the performance of the whole enterprise, meets its business needs, and supports its strategies and investments in change.

A friend of mine Ian Glossop, is doing a survey of views on Enterprise Architecture, and as many of you are Enterprise Architects he would appreciate your views on the subject.

I know your time is precious, and the survey is a little long,  but nevertheless may I urge you to take a little time to complete it.

The survey is implemented as a PDF form, with the ability to save the data you enter and so may be completed and emailed back to:

Ian Glossop (  at your convenience.

The form may be downloaded from here:

Ian is doing this as part of an MSc course in Technology Management with the Open University, so he would very much appreciate your help.

The thesis that Ian is testing is twofold really:

  • That there is a common core to the diversity of EA methods/methodologies and
  • That it is a new-ish (if you can call 25 years old ‘new’) integrative discipline.

If you would like a copy of the results, simply let Ian know and he’ll send you something in September or October.


Business Architecture

23 March 2013

Tom Graves recently participated in an Open Group TweetJam on Business Architecture. You can read about the results of this at

Unfortunately I didn’t hear about this in time to participate but I thought I’d record my own thoughts here.

The questions were:

  1. How do you define Business Architecture?
  2. What is the role of the business architect? What real world business problems does Business Architecture solve?
  3. How is the role of the business architect changing? What are the drivers of this change?
  4. How does Business Architecture differ from Enterprise Architecture?
  5. How can business architects and enterprise architects work together?
  6. What’s in store for Business Architecture in the future?

How do you define Business Architecture?

Business Architecture is one of the primary domains within Enterprise Architecture. It deals with the architecture of the business, ideally from a business perspective and is expressed in business terminology.

It should not really be considered a separate discipline from Enterprise Architecture but often is by those who persist in misunderstanding that Enterprise Architecture is only about IT and not about the whole of the enterprise.

Business Architecture deals with the structure and design of how an enterprise operates, makes money or delivers value, how it organises itself in order to provide products and business services to its customers, clients and consumers. It should be expressed independently of how the business architecture will be mapped to the underlying application architecture and infrastructure architecture, but is more connected to the business/contextual view of the information/data architecture and will include the organisation architecture.

Business Architecture is centred on the business and the business strategy, not on IT or on the IT Strategy and should not be considered just a source of requirements for IT projects (which is the impression that TOGAF gives of Business Architecture).

In general Business Architecture includes the following deliverables:

BizArch deliverables
A Business Architect is primarily concerned with supporting and advising the senior executives, providing advice and guidance, and influencing decision making for the Business Architecture domain.


What is the role of the business architect? 

As a specialised type of Enterprise Architect, they are in a leadership role, close to business management working for the CxOs to evaluate and elaborate possible future strategic scenarios.

They have a responsibility to guide, recommend and oversee the realisation of the business strategies identified by the CxOs, but they don’t control the business strategy or make the actual investment and strategic change decisions.

What real world business problems does Business Architecture solve?

As a type of Enterprise Architect, a Business Architect deals with strategic change, business transformation activities concerning topics such as:

  • Ecommerce changes
  • Consolidation
  • Cost reduction
  • Process improvement and efficiency
  • New organisation design
  • Mergers & Acquisitions
  • Reuse of shared services
  • New markets
  • Regulatory and legal changes

One should not forget that, by definition, an Enterprise Architecture model covers everything about the enterprise including the environment and market which it operates in, its Business Strategies, its Business Architecture as well as the rest of the Enterprise Architect domains.

How is the role of the business architect changing? What are the drivers of this change?

The role of a Business Architect is becoming much more distinct than it has been. many organisations are maturing their enterprise architecture functions that were previously just centred on IT architecture and are now specifically introducing a Business Architect role.

How the Business Architect role differs from other roles such as a Business Analyst, Business Change manager, Business Transformation Manager etc. is still playing out. I discussed this to some extent in a previous blog post – The difference between a Business Architect and a Business Analyst.

Another current difference is that a Business Architect is often closely associated with the Business units (and perhaps reports to a business line manager of sorts) and therefore is seen as being on the ‘Demand’ side of a business, whereas the rest of the Enterprise Architects (including IT Architects) are often lumped into the IT department and therefore are seen as being on the ‘Supply’ side. In theory, the Enterprise Architects, including Business Architects, should only ever be on the ‘Demand’side and not seen as part of IT. They should report to the CxOs, ideally seen as part of a CEO Office.

How does Business Architecture differ from Enterprise Architecture?

A Business Architect is a type of (a ‘real’) Enterprise Architect. Business Architecture is a sub domain of Enterprise Architecture.

EA domains

How can business architects and enterprise architects work together?

Of course they can. The distinction in the question is artificial anyway, since a Business Architect is just a type of Enterprise Architect that specialises in the Business Architecture domain.

But in reality many organisations do have an unfortunate  tendency to make up their own interpretation of what these roles actually are.

What’s in store for Business Architecture in the future?

We will see more and more Business Architecture roles in the future as organisations mature their enterprise architecture strategy and capabilities, and they realise that they need to get to grips with their business model and how it is realised. They will need Business Architects to help them do that.

Business Architecture

For most enterprises embarking on large scale strategic planning and business transformation programmes it is all about staying robust, viable and efficient, continuing to deliver good outcomes and value to their customers/consumers/clients in the future. Enterprises should be wanting to stay competitive and efficient and beat the competition.
If the enterprise is to succeed, it must make strategic decisions and investments in change based on a thorough architectural gap analysis/impact analysis that is only possible with business architecture as a key part of their enterprise architecture function.
