This anthology from the Tetradian weblog explores how economics and enterprise architectures interrelate with each other, in business, in society, and with the wider world.

This book includes about 40 posts and 40 images from the weblog. These posts are split into six groups:

- Economics and Architecture: On Architectures - shows how architecture outlines key flaws in economics, and what it can do to help address them.

- Economics and Architecture: Business - illustrates how economics-level issues can impact everyday business.

- Economics and Architecture: Money - assesses how perspectives on money, price and value can both introduce useful ideas or constrain new possibilities.

- Economics and Architecture: Society - uses architectures-methods to explore effects of current economics at whole-of-society levels.

- Economics and Architecture: Futures - reviews economics implications highlighted by futures-analysis.

- Economics and Architecture: Beyond Money - explores an architecture-based thought-experiment on a form of economics that does not need money to function.

This anthology from the Tetradian weblog focusses on futures, and particularly the techniques and methods needed to guide change for an individual organisation, for a broader shared enterprise, or at a more global big-picture scale, and also across any timescale that may be required.

This book includes about 40 posts and 70 images from the weblog. These posts are split into four groups:

- Futures: Methods - outlines some of the methods and concerns in futures-work for architectures.

- Futures: Architectures - explore a range of issues where futures concerns intersect with architectures in a business context.

- Futures: Politics - uses futures-methods to identify a swathe of fundamental flaws in many current concepts of politics and society, and suggest what can be done to resolve those flaws.

- Futures: Assessments - applies futures-methods to assess potential challenges and options in broader social change, and also in architecture itself.

This anthology from the Tetradian weblog tackles the issues around power and responsibility - or lack of them - and how these affect not just our architectures and organisations but society as a whole.

This book includes about 40 posts and 50 images from the weblog. These posts are split into four groups:

• Power and Society: Responsibilities and Rights - assesses the relationships between rights and responsibilities, and how concepts of power underpin both.
• Power and Society: Architecture and Responsibility - reviews how issues around power and responsibility can impact on the requirements and concerns for our architectures.
• Power and Society: Irresponsibility - outlines the challenges that arise when individuals, organisations, industries or entire societies align around a systematic and often intentional irresponsibility.
• Power and Society: Power and the Person - explores how power-issues affect the individual, particularly in the context of work

This anthology from the Tetradian weblog explores the various forms of complexity that arise in enterprise architecture, and how to work with them.

This book includes about 40 posts and 95 images from the weblog. These posts are split into four groups:

• Complexity: Complexity and Chaos - explores core concepts around complexity in business and beyond.
• Complexity: Complexity and Sensemaking - shows how make sense of complexity in architectures.
• Complexity: Complexity and Method - introduces methods and practices to tackle complexity.
• Complexity: Complexity and SCAN - illustrates how to use the SCAN frame to map out, make sense of and take action on complexity.

This anthology from the Tetradian weblog provides checklists, models and schemas to guide sensemaking practice for enterprise architecture and a wide range of other related disciplines.

The book includes about 35 posts and 90 images from the weblog, and is split into three sections:

• Sensemaking: Making Sense - maps out a range of methods and options for sensemaking in enterprise architecture and beyond.
• Sensemaking: Metaframeworks - presents guidelines and worked-examples on metaframeworks (frameworks used to create sensemaking-frameworks) for enterprise architecture and more.
• Sensemaking: Seven Sins - introduces a set of seven common patterns of sensemaking-failure, and their implications in real-world practice.

This anthology from the Tetradian weblog explores the nature of value and its relationship with the role of enterprise architecture.

This book includes about 35 posts and 65 images from the weblog. These posts are split into four groups:

• Value and Values - outlines the practical meaning of ‘value’ and the distinctions between ‘value’ and ‘values’.
• Values and Quality - provides an overview of quality as an expression of values, and how to use this in enterprise architecture.
• Economics and Value - describes how money is only one subset of value, and the implications of this fact for enterprise architecture and business architecture.
• Effectiveness and Value - shows how values determine the practical meaning of ‘effectiveness’, and how effectiveness supports value in the enterprise.

This anthology from the Tetradian weblog explores notions of theory in enterprise-architecture and the like, from mainstream IT-centric views to whole-enterprise architectures and beyond.

This book includes about 40 posts and 65 images from the weblog. These posts are split into four groups:

• Theory: Patterns - reviews the underlying concepts and definitions for a wide range of architecture concerns and patterns.
• Theory: Technology - assesses how problems in technology and architecture often arise from a poor grasp of underlying theory.
• Theory: Science - considers how we need to use science itself to test the science we use in our architectures and more.
• Theory: Scale - explores how theory itself can break down at different scales, and will need to be adapted to work well in those contexts.

"Theory informs practice; practice reinforms theory". This anthology from the Tetradian weblog explores how theory and practice support each other, in the transition from initial plan to real-world implementation of an architecture.

This book includes about 35 posts and 45 images from the weblog. These posts are split into two groups:

- *From Theory* - outlines some essential theory and guiding-principles for working on enterprise-architectures and more.

- *To Practice* - provides practical guidance on common issues that can arise during development for various types of architecture.

This anthology from the Tetradian weblog focuses on tools and frameworks used in IT-oriented enterprise-architecture.

This book includes about 40 posts and 35 images from the weblog. These posts are split into two groups:

• Frameworks: IT-oriented - assesses key frameworks for IT-oriented architectures, and issues arising from usages of those frameworks.
• Frameworks: Zachman - reassesses the various elements of the row-and-column Zachman framework, in particular via the series of posts on ‘Rethinking Zachman’.

This anthology from the Tetradian weblog focuses on tools and frameworks used in various forms of enterprise-architecture, typically beyond IT alone.

This book includes about 35 posts and 75 images from the weblog. These posts are split into eight small groups:

• Frameworks: SCORE and Strategy - describes the purpose and usages of the SCORE tool for high-level planning and strategic review.
• Frameworks: Change-Mapping - addresses specific aspects of the Change-mapping framework for guidance of change.
• Frameworks: NOTES - introduces the NOTES framework, a story-oriented method for architecture development and validation.
• Frameworks: The This Game - presents a game-like method for modelling the elements of an enterprise.
• Frameworks: VPEC-T - discusses applications for the VPEC-T framework (Values, Policies, Events, Content, Trust) developed by Carl Bate and Nigel Green.
• Frameworks: Spiral Dynamics - outlines a reframe for the Spiral Dynamics model of social-dynamics.
• Frameworks: Other Frameworks - provides overviews and summaries for a variety of other tools and frameworks.
• Frameworks: Related-Themes - explores a wide range of other topics related to frameworks and tools for architectures.

This anthology from the Tetradian weblog presents a variety of posts on enterprise-architecture that either did not seem to fit any other category, or provided context for those uncategorised posts.

The complete book includes about 40 posts and 90 images from the weblog. These posts are split into four groups:

• Loose Ends: Perspectives - reviews a range of perspectives on enterprise-architecture and more.
