# How to use this book

Richard Feynman was famous for explaining hard ideas in simple words. His
learning method is easy:

1. **Learn one small idea.**
2. **Close the page.**
3. **Explain it as if you are teaching a child.**
4. **Notice where your explanation becomes fuzzy.**
5. **Study that small gap, then explain it again.**

This book follows that pattern. Each section has:

- a plain explanation;
- one example;
- a memory hook; and
- a **say it back** challenge.

Do not try to memorize every sentence. Build the picture in your head.

<div class="big-idea">
<strong>Your finish line:</strong> You can explain TOGAF without using the word
“TOGAF” in the explanation.
</div>

## Our one example: Sunny Toys

Sunny Toys has ten shops. It wants customers to:

- see which toys are available;
- buy online;
- collect from any shop; and
- receive the same good service everywhere.

Today, every shop works differently. Stock numbers are often wrong. There are
three customer lists and five old applications. Sunny Toys needs coordinated
change—not just a new website.

We will use Sunny Toys for the whole book.

<div class="teach-back">
<strong>Say it back:</strong> What are the five steps in the Feynman learning
loop? Explain them without looking.
</div>

# 1. What TOGAF is

Imagine a town wants to build homes, roads, schools, pipes, and parks.

If every builder works alone:

- one road may end at a wall;
- pipes may not reach the homes;
- two schools may be built where only one is needed; and
- the town may spend money without becoming a better place to live.

The town needs a shared plan. It also needs a way to create, check, and update
that plan.

An enterprise has the same problem. Its “roads and buildings” are:

- people and teams;
- business capabilities and processes;
- information;
- applications;
- technology; and
- projects and products changing all of them.

**Enterprise Architecture** is the shared picture and decision discipline that
keeps those parts moving toward the same outcomes.

**TOGAF** is a framework for doing Enterprise Architecture. It gives you:

- a repeatable method;
- a shared vocabulary;
- ways to describe architecture;
- analysis techniques;
- governance practices; and
- advice for building an architecture capability.

<div class="big-idea">
<strong>Shortest correct explanation:</strong> TOGAF helps an organization
understand where it is, decide where it wants to go, plan the changes, and keep
delivery moving in that direction.
</div>

## What TOGAF is not

TOGAF is not:

- a finished architecture you can copy;
- a software product;
- a diagramming language;
- a project management method;
- a command to create every possible document; or
- a rigid waterfall.

It is a **method and toolbox**. You choose the parts that help with the real
decision.

## Three words that sound bigger than they are

| Word | Simple meaning |
|---|---|
| Enterprise | The organization or part of it that we are studying |
| Architecture | The important structure, relationships, and rules |
| Framework | An organized set of ideas and tools for doing the work |

<div class="teach-back">
<strong>Say it back:</strong> Explain TOGAF using the town analogy. Then explain
why TOGAF is not a finished town plan.
</div>

# 2. The whole TOGAF story

Every useful architecture journey answers the same questions:

<div class="journey">
  <div><b>1</b><span><strong>Why?</strong><br>Why must we change?</span></div>
  <div><b>2</b><span><strong>Who?</strong><br>Who cares, and what worries them?</span></div>
  <div><b>3</b><span><strong>Now?</strong><br>What matters about today?</span></div>
  <div><b>4</b><span><strong>Future?</strong><br>What should tomorrow look like?</span></div>
  <div><b>5</b><span><strong>Gap?</strong><br>What must change?</span></div>
  <div><b>6</b><span><strong>Order?</strong><br>What should happen first?</span></div>
  <div><b>7</b><span><strong>Build?</strong><br>Are we following the plan?</span></div>
  <div><b>8</b><span><strong>Learn?</strong><br>Did it work, and what changed?</span></div>
</div>

For Sunny Toys:

1. **Why?** Customers leave because stock information is wrong.
2. **Who?** Customers, shop staff, managers, finance, security, and delivery
   teams all care about different things.
3. **Now?** Each shop has separate processes, data, and applications.
4. **Future?** One joined-up buying and collection experience.
5. **Gap?** Shared stock data, clearer ownership, connected applications, staff
   training, and reliable technology are missing.
6. **Order?** Clean stock data before promising real-time availability.
7. **Build?** Check each release against the agreed requirements.
8. **Learn?** Measure collection success, stock accuracy, customer happiness,
   cost, and new risks.

<div class="memory">
<strong>Memory hook:</strong> Why → Who → Now → Future → Gap → Order → Build →
Learn.
</div>

<div class="teach-back">
<strong>Say it back:</strong> Close this page and draw the eight questions as a
circle. If one question is hard to explain, that is your next study gap.
</div>

# 3. The ADM: TOGAF's main method

The **Architecture Development Method**, or **ADM**, is the heart of TOGAF.

It organizes architecture work into:

- a setup phase;
- eight lettered phases, A through H; and
- Requirements Management in the middle.

Use this mnemonic:

<div class="mnemonic">
Prepare A Business; Connect Digital Execution For Governed Horizons.
</div>

That gives you **P-A-B-C-D-E-F-G-H**.

## Preliminary Phase — Prepare

**Simple question:** How will we do architecture here?

Before planning Sunny Toys, the organization agrees:

- who makes which decisions;
- which method and documents are useful;
- which principles guide choices;
- where architecture knowledge is stored; and
- how architects work with leaders and delivery teams.

**Main result:** a working architecture capability—not merely an architecture
team.

## Phase A — Agree the Architecture Vision

**Simple question:** Why are we doing this, for whom, and how big is the work?

Sunny Toys agrees:

- the desired customer outcome;
- the sponsor;
- stakeholders and concerns;
- what is inside and outside scope;
- high-level baseline and target;
- success measures and risks; and
- permission to continue.

**Main results:** the **Architecture Vision** and **Statement of Architecture
Work**.

## Phase B — Business Architecture

**Simple question:** How should the business work?

Sunny Toys designs:

- the buy-and-collect value stream;
- shop and online capabilities;
- staff responsibilities;
- customer service;
- business rules; and
- ownership of stock accuracy.

**Main result:** business baseline, target, and gaps.

## Phase C — Information Systems Architectures

Phase C contains two domains.

### Data Architecture

**Simple question:** What information do we need, and who looks after it?

Sunny Toys defines:

- one meaning for Product, Shop, Stock, Customer, Order, and Collection;
- an owner for each important kind of data;
- where trusted data comes from;
- how it moves; and
- privacy, quality, retention, and access rules.

### Application Architecture

**Simple question:** What applications and services use that information?

Sunny Toys decides how the website, stock service, payment service, shop
application, notification service, and reporting tools work together.

**Main result:** data and application baselines, targets, and gaps.

## Phase D — Technology Architecture

**Simple question:** What technology lets the target work safely and reliably?

Sunny Toys chooses the needed:

- platforms and hosting;
- networks and shop connectivity;
- identity and access services;
- monitoring and backup;
- integration technology; and
- technology standards and lifecycle rules.

**Main result:** technology baseline, target, and gaps.

## Phase E — Opportunities & Solutions

**Simple question:** How do we turn all the gaps into sensible pieces of work?

Sunny Toys groups changes into work packages:

1. create trusted stock data;
2. connect shop systems;
3. launch online ordering;
4. add collection notifications; and
5. improve reporting and operations.

It may define **Transition Architectures**—safe intermediate states on the way
to the target.

**Main result:** work packages and candidate transition architectures.

## Phase F — Migration Planning

**Simple question:** What should happen first, and can we really do it?

Sunny Toys compares:

- value;
- cost;
- risk;
- dependencies;
- people and skills;
- readiness; and
- time.

**Main results:** a prioritized **Architecture Roadmap** and an executable
**Implementation and Migration Plan**.

## Phase G — Implementation Governance

**Simple question:** Is delivery building what was agreed?

Sunny Toys:

- agrees responsibilities and review points;
- checks important requirements;
- reviews evidence;
- handles justified exceptions; and
- avoids turning governance into a slow approval queue.

**Main results:** Architecture Contracts or equivalent agreements, compliance
evidence, decisions, and managed deviations.

## Phase H — Architecture Change Management

**Simple question:** Has the world changed enough to update the architecture?

Sunny Toys watches:

- business outcomes;
- customer behavior;
- operating problems;
- new laws and risks;
- technology changes; and
- architecture debt.

A small change may update one decision. A big change may start a new ADM cycle.

**Main result:** a living architecture instead of an old document.

## Requirements Management — the center

A **requirement** says what must be true.

Example: “A customer must only see stock that can be reserved.”

Requirements Management stays in the center because every phase:

- discovers requirements;
- uses requirements;
- tests requirements;
- changes requirements; or
- is changed by requirements.

<div class="adm-grid">
  <div><b>P</b><span>Prepare the practice</span></div>
  <div><b>A</b><span>Agree the vision</span></div>
  <div><b>B</b><span>Design the business</span></div>
  <div><b>C</b><span>Design data and apps</span></div>
  <div><b>D</b><span>Design technology</span></div>
  <div><b>E</b><span>Package the changes</span></div>
  <div><b>F</b><span>Prioritize the journey</span></div>
  <div><b>G</b><span>Govern the build</span></div>
  <div><b>H</b><span>Watch and adapt</span></div>
  <div class="requirements"><b>R</b><span>Requirements connect everything</span></div>
</div>

<div class="important">
<strong>Do not treat the ADM as a waterfall.</strong> You may revisit earlier
work, combine phases, run work in parallel, or use small cycles. Tailor it to
the decision, risk, and delivery speed.
</div>

<div class="teach-back">
<strong>Say it back:</strong> Draw P through H. For each phase, say its question
in one sentence. Put Requirements Management in the center and explain why.
</div>

# 4. The four architecture domains: BDAT

Use **BDAT**:

| Domain | Child-simple question | Sunny Toys example |
|---|---|---|
| **B — Business** | How do people create value? | Buy online and collect in a shop |
| **D — Data** | What information do they need? | Product, stock, customer, order |
| **A — Application** | What software behavior helps them? | Website, stock, payment, shop app |
| **T — Technology** | What machinery lets the software run? | Cloud, network, identity, monitoring |

The domains are different, but they must fit together.

If the business promises one-hour collection, then:

- Data must show trustworthy stock.
- Applications must reserve the toy.
- Technology must keep the service available.
- People and processes must prepare the collection.

Security, risk, privacy, integration, customer experience, and sustainability
cross all four domains. They are not decorations added at the end.

<div class="memory">
<strong>Memory hook:</strong> Business asks for value. Data carries meaning.
Applications provide behavior. Technology provides the platform.
</div>

<div class="teach-back">
<strong>Say it back:</strong> Pick a school, shop, or app. Give one Business,
Data, Application, and Technology example. Then name one cross-cutting concern.
</div>

# 5. The core language

## Stakeholder, concern, view, viewpoint

These four words form one chain:

1. A **stakeholder** is a person or group that cares.
2. A **concern** is what they care about.
3. A **viewpoint** is the rule for creating a useful picture.
4. A **view** is the actual picture made for this architecture.

Example:

- Stakeholder: shop manager
- Concern: “Will collection create long queues?”
- Viewpoint: show the customer and staff journey with timings
- View: Sunny Toys' actual collection journey diagram

## Baseline, target, gap, transition, roadmap

| Term | Simple meaning |
|---|---|
| Baseline | The important truth about today |
| Target | The future we intend to create |
| Gap | A difference that needs action |
| Transition Architecture | A safe intermediate version of the enterprise |
| Roadmap | The ordered path through the changes |

## Driver, goal, outcome, requirement, measure

| Term | Sunny Toys example |
|---|---|
| Driver | Customers expect online ordering |
| Goal | Make buying and collection easy |
| Outcome | More completed sales with fewer stock mistakes |
| Requirement | Reserved stock must not be sold to someone else |
| Measure | Collection success rate and stock accuracy |

## Principle, constraint, assumption, risk

| Term | Simple meaning |
|---|---|
| Principle | A lasting rule that guides decisions |
| Constraint | A limit we must work within |
| Assumption | Something we currently believe is true |
| Risk | Uncertainty that may affect an outcome |

Example principle: **Stock has one trusted owner.**

Example constraint: **The first release must use existing shop scanners.**

Example assumption: **Every shop has stable internet access.**

Example risk: **Old stock records may be too inaccurate for online promises.**

<div class="teach-back">
<strong>Say it back:</strong> Explain each chain without reading:
stakeholder → concern → viewpoint → view, and baseline → target → gap →
transition → roadmap.
</div>

# 6. What architects produce

TOGAF distinguishes three things.

## Deliverable

A **deliverable** is a formally reviewed package of work.

Think: a school project handed to the teacher.

Examples:

- Architecture Vision;
- Architecture Definition Document;
- Architecture Requirements Specification;
- Architecture Roadmap; and
- Implementation and Migration Plan.

## Artifact

An **artifact** is a representation of architecture information inside or
alongside the work.

There are three simple forms:

| Form | It answers | Example |
|---|---|---|
| Catalog | What exists? | Application list |
| Matrix | How are things related? | Capability-to-application matrix |
| Diagram | How should we see it? | Application interaction diagram |

## Building block

A **building block** is a reusable unit of capability or solution.

- An **Architecture Building Block (ABB)** says what capability is needed.
- A **Solution Building Block (SBB)** says how it will be implemented.

Sunny Toys example:

- ABB: “Secure customer identity capability”
- SBB: “The selected identity platform and its configured services”

<div class="memory">
<strong>Memory hook:</strong> A deliverable is the reviewed package. An artifact
is a picture or structured list. A building block is a reusable piece of the
architecture or solution.
</div>

## The minimum useful architecture pack

Do not create documents because a framework has a template. For many
engagements, a small useful pack is:

1. outcome, scope, sponsor, and stakeholders;
2. principles, assumptions, constraints, and risks;
3. relevant baseline;
4. target choices across the necessary domains;
5. traceable requirements and decisions;
6. gaps, work packages, and roadmap;
7. governance and exception approach; and
8. measures of success.

<div class="teach-back">
<strong>Say it back:</strong> Explain deliverable, artifact, ABB, and SBB using
building a tree house as your example.
</div>

# 7. Reuse and the Architecture Repository

Imagine a kitchen.

The **Enterprise Continuum** is the labeling idea that sorts recipes and
ingredients from very general to very specific.

The **Architecture Repository** is the actual pantry, cookbook shelf, fridge,
and list that store and control them.

<div class="compare">
  <div>
    <strong>Enterprise Continuum</strong>
    <span>Classifies knowledge from generic to organization-specific.</span>
  </div>
  <div>
    <strong>Architecture Repository</strong>
    <span>Stores, controls, connects, and helps people reuse knowledge.</span>
  </div>
</div>

The Continuum has two related sides:

- **Architecture Continuum:** reusable architecture ideas and descriptions.
- **Solutions Continuum:** products, services, and implemented solutions.

Common Repository areas are:

| Area | Simple contents |
|---|---|
| Architecture Metamodel | Rules about the kinds of information and relationships |
| Architecture Capability | Roles, method, governance, skills, and tools |
| Architecture Landscape | Baseline, transition, and target descriptions |
| Standards Information Base | Approved standards, products, versions, and lifecycle |
| Reference Library | Patterns, templates, reference models, and lessons |
| Governance Log | Decisions, reviews, exceptions, risks, and debt |

Good repository content has an owner, status, version, and review date.

<div class="teach-back">
<strong>Say it back:</strong> Use the kitchen analogy to explain the difference
between the Enterprise Continuum and Architecture Repository.
</div>

# 8. Governance without becoming the architecture police

Governance means important decisions are:

- made by the right people;
- based on visible criteria and evidence;
- recorded;
- followed during delivery;
- allowed a controlled exception when justified; and
- improved using feedback.

It does **not** mean one central committee designs everything.

Think of road rules:

- rules make movement safer;
- signs make expectations visible;
- drivers still choose their route;
- unusual situations have an exception process; and
- accident evidence helps improve the rules.

## The governance loop

1. Agree principles and standards.
2. Define decision rights.
3. Make and record decisions.
4. Agree implementation responsibilities.
5. Review evidence of conformance.
6. Approve, correct, or manage an exception.
7. Measure the outcome.
8. Improve the architecture and rules.

An **Architecture Board** is one governance body. It needs a clear mandate,
authority, decision criteria, membership, and escalation rules. Low-risk
decisions should stay close to delivery.

An **Architecture Contract** is an agreement about responsibilities,
requirements, evidence, reviews, and exceptions. It does not have to be a giant
legal document.

<div class="teach-back">
<strong>Say it back:</strong> Explain why good governance is like road rules,
not like one person driving every car.
</div>

# 9. The small toolbox of techniques

Use a technique only when it helps answer a question.

| Technique | Simple purpose |
|---|---|
| Stakeholder analysis | Find who cares, why, how much influence they have, and how to involve them |
| Business scenario | Turn a fuzzy problem into actors, steps, outcomes, measures, and requirements |
| Capability-Based Planning | Plan around abilities the enterprise needs, not only projects or systems |
| Value-stream mapping | Follow how value moves from a need to an outcome |
| Gap analysis | Compare baseline and target to identify change |
| Readiness assessment | Check whether people, skills, culture, funding, and governance can support change |
| Risk management | Find uncertainty, understand exposure, choose treatment, and keep watching |
| Trade-off analysis | Compare options using explicit criteria and consequences |
| Dependency analysis | Find what relies on what before creating the sequence |
| Transition Architectures | Define safe intermediate states |

## A simple trade-off method

When Sunny Toys must choose a solution:

1. State the decision.
2. Name the stakeholders and concerns.
3. Define criteria and constraints.
4. Create more than one credible option, including “do nothing” where useful.
5. Gather enough evidence—not endless evidence.
6. Compare value, cost, risk, uncertainty, and reversibility.
7. Let the person with the decision right decide.
8. Record the choice, consequences, and revisit trigger.

<div class="teach-back">
<strong>Say it back:</strong> Pick one everyday choice. Compare two options
using outcome, cost, risk, and reversibility.
</div>

# 10. TOGAF with Agile, products, DevOps, cloud, and security

TOGAF and modern delivery solve different parts of the problem.

- TOGAF helps decide the important direction and coordinate change.
- Product management keeps attention on persistent customer value.
- Agile creates short learning loops.
- DevOps makes delivery and operations fast and repeatable.
- Cloud provides on-demand technology services.
- Security and risk protect outcomes across every domain and phase.

They can work together.

Good modern architecture:

- works in small increments;
- gives teams clear guardrails and decision rights;
- records important decisions briefly;
- automates standards and evidence where possible;
- keeps architects close to products and delivery;
- uses operational data to update architecture; and
- escalates only choices with material risk or cross-enterprise impact.

Bad architecture creates a document mountain and arrives after all decisions
have already been made.

<div class="big-idea">
<strong>Useful rule:</strong> Centralize the decisions that require enterprise
coherence. Delegate the decisions that teams can safely make locally.
</div>

<div class="teach-back">
<strong>Say it back:</strong> Explain how TOGAF and Agile can work together.
Your answer must include direction, guardrails, short feedback, and learning.
</div>

# 11. How to start TOGAF in a real organization

Do not announce, “We will implement the whole framework.”

Start with a real business problem.

## Days 1–30: establish the minimum

- Confirm the sponsor and outcome.
- Identify stakeholders and decision rights.
- Agree a small set of principles.
- Tailor the ADM and minimum content.
- Create a simple repository structure.
- Choose one valuable pilot.

## Days 31–60: run the pilot

- Agree the vision and scope.
- Develop only the useful baseline and target.
- Trace requirements and decisions.
- Identify gaps and work packages.
- Build a practical roadmap.
- Work beside delivery teams.

## Days 61–90: connect and improve

- Run proportionate governance and exception handling.
- Measure value, speed, risk, and conformance.
- Reuse patterns and lessons.
- Fix unclear decision rights.
- Expand only what has proved useful.

## Common failure patterns

| Failure | Why it fails | Better move |
|---|---|---|
| Framework-first rollout | People see process, not value | Start with one outcome |
| Artifact factory | Documents grow; decisions do not improve | Produce only decision-useful content |
| Review-board bottleneck | Architecture becomes a queue | Delegate low-risk decisions |
| Ivory-tower target | Delivery evidence arrives too late | Work with product and delivery teams |
| Tool-led metamodel | The repository becomes the goal | Start with questions and users |
| Architecture without authority | Good advice can be ignored | Make decision rights explicit |
| Governance without feedback | Rules become stale | Measure outcomes and learn |

<div class="teach-back">
<strong>Say it back:</strong> Explain how you would begin TOGAF without saying,
“First, create every TOGAF document.”
</div>

# 12. One full Sunny Toys walkthrough

Here is the entire method in one short story.

## Prepare

Sunny Toys gives the transformation sponsor authority. A small Architecture
Board handles only cross-shop decisions. Product teams keep local delivery
choices within shared guardrails.

## Agree

The vision is: “Customers can confidently buy online and collect from any shop
within two hours.” Scope includes stock, ordering, payment, collection, staff
workflow, and enabling technology. It excludes home delivery for now.

## Understand the business

The target value stream is:

**Find toy → reserve → pay → prepare → notify → collect → support**

Shop staff own physical stock accuracy. Customer service owns collection
support. Product leaders own the end-to-end outcome.

## Design information and applications

Product, Shop, Stock, Customer, Order, Payment, and Collection get clear
definitions and owners. A stock service becomes the trusted source. The website
and shop application use the same order and stock services.

## Design technology

The target uses secure identity, managed hosting, reliable shop connectivity,
monitoring, backup, and standard integration. Privacy and security requirements
apply throughout.

## Package and plan

Sunny Toys creates three transition states:

1. accurate shared stock;
2. online reservation with payment at collection; and
3. full online payment and two-hour collection.

The roadmap follows data dependency and business readiness, not excitement
about the website.

## Govern and learn

Each release supplies automated test, security, reliability, and stock-accuracy
evidence. Exceptions have an owner and expiry. Sunny Toys measures customer
completion, stock accuracy, collection time, support calls, cost, and incidents.

Those results update the architecture.

<div class="teach-back">
<strong>Say it back:</strong> Retell the Sunny Toys story without phase letters.
Then add the phase letters to each step.
</div>

# 13. The exam idea, simply

The current Enterprise Architecture learning path has two main levels:

## Foundation

Foundation checks whether you understand:

- core concepts and vocabulary;
- the ADM structure and purpose of each phase;
- foundational techniques;
- applying the ADM;
- governance; and
- architecture content.

The Part 1 examination uses 40 multiple-choice questions in 60 minutes, with a
60% passing score.

## Practitioner

Practitioner checks whether you can apply the framework to a situation.

The Part 2 examination uses eight scenario-based questions in 90 minutes. Each
question has four choices scored 5, 3, 1, or 0. It is open book using the
provided reference material.

## Use SCOPE for scenarios

1. **S — Stakeholders:** Who cares and who decides?
2. **C — Context:** What phase, scope, evidence, and constraints exist?
3. **O — Outcome:** What result or decision is needed?
4. **P — Proportion:** What is the smallest sufficient response?
5. **E — Evidence:** Which choice preserves traceability, trade-offs, and
   feedback?

Prefer answers that clarify outcomes and authority, address concerns, tailor
the work, maintain traceability, and enable governed delivery.

Be suspicious of answers that:

- create every artifact;
- skip straight to technology;
- centralize every choice;
- ignore stakeholder concerns; or
- treat the ADM as a fixed waterfall.

<div class="teach-back">
<strong>Say it back:</strong> Explain the difference between Foundation and
Practitioner. Then use SCOPE on a decision from the Sunny Toys story.
</div>

# 14. One-page memory sheet

## TOGAF in one sentence

TOGAF helps an organization understand where it is, agree where it wants to go,
plan the changes, govern delivery, and keep learning.

## The journey

**Why → Who → Now → Future → Gap → Order → Build → Learn**

## The ADM

| Phase | Remember |
|---|---|
| Preliminary | Prepare the architecture practice |
| A | Agree vision, value, scope, and authority |
| B | Design how the business creates value |
| C | Design data and applications |
| D | Design enabling technology |
| E | Package gaps into work |
| F | Prioritize the migration journey |
| G | Govern implementation |
| H | Watch change and adapt |
| Requirements | Connect and trace everything |

## The domains

**BDAT = Business, Data, Application, Technology**

## The content

- Deliverable = reviewed package
- Artifact = catalog, matrix, or diagram
- ABB = required capability
- SBB = implementation

## Reuse

- Continuum = classifies
- Repository = stores and controls

## Governance

**Decision rights → decision → agreement → evidence → compliance or exception
→ outcome → feedback**

## Scenario thinking

**SCOPE = Stakeholders, Context, Outcome, Proportion, Evidence**

# 16. Prove that you understand

Answer these aloud in simple words:

1. What problem does Enterprise Architecture solve?
2. What does TOGAF give you?
3. Why is the ADM not a waterfall?
4. What question does each ADM phase answer?
