Review: “Communities of Practice within and across Organizations. A Guidebook” (2nd edition) by Etienne Wenger-Trayner, Beverly Wenger-Trayner, Phil Reid and Claude Bruderlein
Most books on organizational learning describe what communities of practice are. This one tells you how to run them. The second edition of the CoP Guidebook, co-authored by four practitioners across corporate, academic, and humanitarian sectors, is the most practically grounded resource on the subject currently available.
Three Stories, One Toolkit
The book’s defining feature is its three-column narrative structure. Rather than illustrating theory with hand-picked case studies, it weaves together three genuinely independent journeys:
- Etienne and Beverly Wenger-Trayner, the conceptual backbone, drawing on over three decades of CoP consulting across private and public sectors
- Phil Reid’s Ignite initiative at JPMorgan Chase, a grassroots technology CoP network grown to cover a global workforce of over 55,000 people
- Centre of Competence on Humanitarian Negotiation (CCHN), a cross-organizational network of frontline humanitarian negotiators operating in conflict zones worldwide, convened by Claude Bruderlein under the International Committee of the Red Cross
Crucially, neither the Ignite nor the CCHN team were advised by Wenger-Trayner when they started. Both independently discovered the framework years later and found it gave them language for what they had already built. This convergence gives the book unusual credibility: it describes practice that emerged organically, not practice designed to confirm a theory.
Use Case 1: Starting a Community From Scratch
One of the most common needs for practitioners is knowing how and when to formally launch a community. Chapter 3 addresses this in detail. The authors distinguish between four different formation options:
- A community of practice for long-term, domain-centered learning partnerships
- A chapter for geographically local versions of a broader community
- A practice group for specialized sub-concerns within a wider domain
- A social learning space for more flexible, lower-commitment arrangements
This taxonomy alone is worth the read. Many organizations waste energy trying to build full-blown communities of practice when a lighter social learning space would serve the purpose just as well, at far lower cost. The book helps you choose deliberately rather than by default.
For the launch itself, the authors offer a counterintuitive concept: the non-launch. Instead of an elaborate kickoff event, a community can quietly begin with informal conversations, a small pilot group, and a value proposition tested before any formal announcement. The Ignite story illustrates this with a 2016 experiment at JPMorgan Chase that only became a named initiative once it had already demonstrated value.
Use Case 2: Facilitating Meetings That Generate Real Learning
Chapter 4 is the most immediately actionable part of the book. It provides over 20 concrete activity formats, each described with purpose, process, and variation options. For practitioners planning community meetings, these include:
- Case Clinic: a structured peer consultation where one member brings a real challenge and others offer perspectives, not solutions
- Design Clinic: collaborative prototyping of a new practice, tool, or approach
- Mutual Benchmarking: members compare their practices across a shared set of dimensions to identify gaps and innovations
- Fishbowl: a rotating inner circle discussion structure that surfaces diverse voices in larger groups
- World Café: small-group rotating conversations that build on each other across rounds
- Practice-Development Projects: multi-session community work to actually produce a shared artifact, methodology, or guidance note
- Storytelling: structured sharing of field experience as a learning resource for peers
- Post-Mortem / Project Review: collective reflection on completed work to extract transferable lessons
Each format is suited to different stages of a community’s life. The authors explain how to sequence them across a community rhythm, the mix of regular meetings and in-between touchpoints that keeps a community alive between annual events.
Use Case 3: Diagnosing a Stalled Community
Many communities of practice start with energy and then slowly lose momentum. Chapter 3’s section on the seven dimensions of maturity is designed precisely for this situation. Rather than a checklist, it offers seven reflective lenses for community leaders:
- Pushing the Practice: Is the community actually advancing members’ capabilities?
- Stewarding the Domain: Is the community maintaining and developing its knowledge base?
- Structuring the Community: Are processes and tools fit for purpose?
- Nurturing Identification: Do members feel they belong?
- Clarifying and Distributing Leadership: Is leadership too concentrated in one person?
- Cultivating Self-Awareness: Does the community understand itself?
- Orienting to the Context: Is the community responsive to its organizational environment?
The CCHN story shows how a humanitarian negotiation community applied this kind of self-diagnosis to evolve from informal peer exchanges into a globally recognized professional community, holding summits in Switzerland and influencing field practice across multiple agencies.
Use Case 4: Making the Case to Sponsors
Chapter 2, focused on the organizational perspective, directly addresses the challenge of sustaining institutional support. It describes sponsorship roles, community registries, induction processes for new staff, and the relationship between a social learning team and senior sponsors. This is especially relevant for organizations in international development, where CoPs often depend on donor goodwill and must justify their overhead.
Chapter 6 takes this further with the Value Creation Framework, which maps four cycles of value:
- Immediate value: the direct usefulness of a meeting or interaction
- Potential value: knowledge and relationships held in reserve
- Applied value: changes in practice that result from community participation
- Realized value: measurable organizational outcomes
The framework also integrates value-creation stories as qualitative evidence alongside quantitative indicators. For accountability-driven organizations, this gives CoP leaders a credible narrative for program reviews and donor reports, not just anecdotal praise.
Use Case 5: Scaling Across a Large Organization
The Ignite story at JPMorgan Chase is the go-to reference for anyone managing a multi-community initiative. Phil Reid describes how Ignite built a common brand, shared templates, training for community leaders, a community of community leaders, and a certification pathway borrowed from Agile methodology. The Ignite story demonstrates that scaling is not just about replication: it requires deliberate governance, visible sponsorship, and constant attention to the question of whether local communities feel supported rather than controlled.
The ABInBev appendix, added in the second edition, provides a useful counterpoint: a top-down initiated corporate CoP program with structured roles, a “Sensei” designation for master practitioners, and a content factory model. Comparing the two approaches helps practitioners understand what works in different organizational cultures.
Use Case 6: Cross-Organizational and Cross-Boundary Communities
The CCHN case is the book’s most distinctive contribution for readers in civil society, humanitarian work, and international development. It demonstrates how a community of practice can span multiple organizations, including direct competitors for funding and mandates, without dissolving into a network or task force. The key design principle is that members participate as individual learners, not as organizational representatives. This protects the psychological safety needed for honest peer exchange, even in politically sensitive contexts.
This model is directly transferable to cross-sector communities in areas like biodiversity finance, anti-corruption governance, or seed system development, where practitioners from governments, NGOs, and donors share challenges but are separated by organizational loyalties.
What the Book Does Not Do
The authors are honest about the limits of their approach. The book explicitly does not offer a single correct model to replicate. It does not provide ready-made metrics, and the three-column layout, though conceptually elegant, can feel dense when reading the PDF on a small screen. The printed color edition handles this better. Practitioners looking for a quick-start checklist will need to invest patience before the book rewards them.
Who Should Read It
| Role | Most Relevant Chapters |
| CoP initiative leader | 2, 6 |
| Community facilitator or leader | 3, 4 |
| Organizational sponsor | 1, 2, 6 |
| Evaluator or M&E specialist | 6 |
| New community member taking on responsibility | 3, 4 |
Verdict
The CoP Guidebook fills a genuine gap in the literature on organizational learning. It combines conceptual rigor with the kind of hands-on detail that practitioners actually need, without tipping into prescriptivism. The free PDF download makes it accessible to any organization regardless of budget. For anyone working with knowledge communities in complex, multi-stakeholder environments, this is a reference worth keeping open, not just reading once.
Highly recommended.
