I started this book because I kept running into the same conversation. A public manager or a nonprofit executive director would describe a hard choice — close a service to fund a better one, take on political risk for a longer-term outcome, spend money that will not show a return within the current electoral or funding cycle — and reach for a vocabulary that did not quite fit. The language of the market (efficiency, return on investment, willingness to pay) captured part of it but not the part that mattered most: that they were spending resources that belonged, collectively, to citizens, and needed an argument for why that spending was authorised. The language of pure democratic mandate captured another part — that a vote or a statute gives permission — but not the part where permission is not enough, because capacity to deliver still has to be built and evidence of value still has to be made. What was missing was a name for the third thing standing between those two: value that citizens, as a collective, would authorise spending collective resources to produce, and that an organisation is actually capable of delivering.

That third thing is public value, and the person who gave it its clearest working shape was Mark Moore, whose 1995 book Creating Public Value: Strategic Management in Government set out what this guide calls the strategic triangle: a public or social-sector strategy succeeds only when it holds together legitimacy and support (the authorising environment that permits and sustains the work), a public value proposition (what the organisation is actually trying to create for citizens and society), and operational capacity (whether the organisation can actually deliver it). Take any one leg away and the strategy fails, however sound the other two look on their own. A programme with legitimacy and capacity but no real value proposition is legal and deliverable but pointless. One with a compelling value proposition and capacity but no legitimacy will not survive contact with its authorising environment. One with legitimacy and a value proposition but no capacity is a promise the organisation cannot keep. Three decades of scholarship and practice since Moore's book — from Benington, Stoker, Osborne, Bozeman, Alford, and Bryson, Crosby, and Bloomberg, among others — have tested, extended, and argued with the triangle, and this guide draws on that fuller body of work rather than treating the original formulation as the last word. The triangle earns a book of its own because it is not a slogan; it is a discipline, with tools, failure modes, and a maturity curve, and public and social-sector leaders deserve those tools laid out with the same rigour that management theory affords the private sector.

This book is written for the people who carry that discipline in practice: permanent secretaries and agency heads, elected and appointed local-government leaders, nonprofit and social-enterprise executive directors, policy and programme directors, and the digital, finance, and operations leaders who serve them. If you have ever had to justify a budget line, a service redesign, or a hard trade-off to a board, a minister, a funder, or the public, this book is addressed to you directly.

The guide is organised into five parts, plus this preface as front matter. Part 1, Foundations, sets out why public value is different from market value or democratic mandate alone, and the models — the strategic triangle chief among them — that explain it. Part 2, Evaluation and Evidence, is the analyst's toolkit: valuing outcomes, building the case, and testing claims, from the public value scorecard to cost-benefit analysis, social return on investment, and evidence synthesis. Part 3, Systems, Governance and Priorities, covers how public and social-sector organisations are actually structured, funded, and held accountable — administration models, policy, finance, procurement, workforce, and risk. Part 4, Global and Societal Issues, moves beyond any one institution to behaviour, trust, climate, and the public conversation. Part 5, Digital, Software, and Technology, treats digital government, artificial intelligence, software, data, and cybersecurity as public value questions in their own right, not merely technical afterthoughts.

Every numbered topic follows the same structure, deliberately, so that once you know how to read one, you know how to read all thirty-three. Each opens with a one-sentence thesis, then builds the core concepts you need before the rest makes sense, then sets out best practices you can act on directly. Six discussion questions, each with enough briefing to use without the topic open, are written for you to take into a room with your own team. A worked example — always fictional, always clearly labelled as illustrative — shows the ideas applied to a scenario, followed by four sector lenses (local government, national government, social sector and nonprofit, and multilateral and international) that name what genuinely differs about applying the topic in each context, rather than repeating the topic with the sector's name changed. Each topic then names its common failure modes, offers a five-level maturity model (Initiate, Develop, Standardise, Manage, Orchestrate) so you can place your own organisation on the curve, and closes with a checklist and its sources. Topics are written to stand alone, so you can start wherever your own problem sits and expand an acronym or a term again even if you met it in an earlier topic.

The scope of this book is worldwide, and deliberately so. National governments, regional and local government, social enterprises, nonprofits and NGOs, and multilateral and international bodies all appear as first-class subjects, not as variations on a single national template. Where a named institution appears, it is there as an exemplar of a pattern — a way a certain kind of body has approached a certain kind of problem — not as the one right answer or the default case. This book does not assume any particular country's constitutional or administrative arrangement, and it asks you to translate its patterns into your own.

A short, honest note on how this book was made. It is written with the assistance of artificial intelligence, grounded in verified sources — Wikipedia references checked to resolve, claims drawn from the established public-administration and public-value literature and from bodies such as the OECD, the World Bank, and the United Nations, and figures described qualitatively rather than invented where a precise statistic could not be verified. Eleven of the fifteen locales this guide is published in — cy-gb and cy-001, both Welsh, es-001, Spanish, zh-cn, Chinese, ar-001, Arabic, hi-in, Hindi, fr-001, French, de-de, German, ja-jp, Japanese, ru-ru, Russian, and ko-kr, Korean — are AI-translated drafts, produced from the canonical English text and not yet reviewed by a professional editor in the relevant language; treat them as a working draft rather than a finished text, particularly for public-facing or funded use, until that review has happened.

Finally, a word on what this book is not, so that you calibrate your expectations correctly before you start. It is not a constitutional law textbook, a jurisdiction-specific compliance manual, an econometrics or statistics textbook, vendor documentation for any named platform, or a legal authority binding on any one jurisdiction; it describes patterns of practice, worldwide but not encyclopaedic, and leaves the law, the statistics textbook, and the compliance manual to their own specialists.
