An executive summary or abstract goes here. Should focus on the main findings and recommendations.


Open online communities like Wikipedia, OpenStreetMap, WikiHow, Zooniverse, and Imgur support self-organized, cooperative work by distributed networks of volunteers. Both CSCW researchers and industry practitioners who support these open collaboration systems (OCSs) communities seek to build understanding about the nature of open collaboration. However, there are few opportunities for academic and industry researchers to communicate and collaborate.

On March 14, 2015 in Vancouver, British Columbia we brought together stakeholders across the OCS research ecosystem to discuss the state of open collaboration research and practice, and to develop recommendations for advancing the field of OCS research and improving outcomes for OCS creators, contributors, users, and community organizers. We developed a program around two broad questions:

  • What are the most pressing questions pertaining to our scientific understanding of OCSs?
  • How can we improve collaboration and data-sharing between academia and industry?

The workshop was held during the annual Computer-Supported Cooperative Work and Social Computing (CSCW) conference of the Association for Computing Machinery (ACM). CSCW was chosen as a venue because a large volume of high quality research on OCSs is published in its annual proceedings.


This document is intended to provide scholars, designers, managers, and communities with a set of relevant, current considerations for OCS research and practice agreed upon by leading researchers in the field. This document can serve as a reference point for future research, to direct new work and help justify it. OCS stakeholders may use it to identify knowledge gaps, research opportunities, and design directions, and to argue both the academic merit and practical utility of specific new initiatives that were called for in this workshop.


The program consisted of a series of ~45 minute breakout sessions interspersed with lightning talks and roundtable discussions. During each breakout, a team of 4-5 participants discussed issues related to the workshop’s themes (Access and Theory), taking notes on a dedicated etherpad. Throughout the day, select participants from OCS organizations and academic institutions gave 6-8 minute talks that focused on their research (in the case of academics) or the history and dynamics of the OCSs they support (in the case of industry professionals).

During ‘Access’ breakouts, teams focused on challenges that various stakeholders (e.g.. professors, research scientists, community contributors) face related to data sharing, as well as strategies for facilitating more effective collaboration, proposals for best practices, and a frank discussion of incentive structures within their organizations.

During ‘Theory’ breakouts, teams assessed the state of OCSs research, examining issues such as the potential benefits and limitations of current theoretical approaches, and the generalizability and practical applicability of findings from the current body of research, published in ACM conference proceedings and elsewhere.

After each round of breakout sessions, one member of each team summarized the team’s key findings and questions for the rest of the workshop participants, who had the opportunity to question and comment during an informal roundtable discussion. During the afternoon breakouts, teams focused on synthesizing and prioritizing their notes from the morning session into 2-3 main points.

After the workshop a self-selected group of organizers and participants performed an additional synthesized the [six] groups’ notes, and grouped them together under four thematic headings (Practical theory, Comparative analysis, Shared research infrastructure, and Collaborations). The writers then proposed a set of concrete steps for all members of the OCS research community, based on the issues and proposals raised during the workshop. We believe that the considerations, priorities, and recommendations presented here represent a basic consensus among a diverse set of stakeholders that can help build and sustain a community of practice around OCSs that spans individuals, institutions, disciplines, communities, and technologies.

Research directions[edit]

In this section, we provide a summary of recommendations for the future of the field that emerged from the workshop. These recommendations are provided to highlight perceived gaps in our current understanding of OCSs or in our approach to OCS research and design, to direct attention to emerging research opportunities, and to help develop a consensus around “best practices” for collaborative work in our community. The recommendations are grouped according to four general themes: Practical theory, Comparative analysis, Shared research infrastructure, and Collaborations.

Practical theory[edit]

There is a substantial gap between theory of OCSs and practice. While “A/B tests” are common in industry, they tend to be used “atheoretically”, or only to address immediate questions about a specific software change. Academics work to push theory forward, though not necessarily to get their design recommendations implemented. As a result, design and evaluation of living OCS systems is seldom informed by theory.

Further, the academic distance between disciplines that tend to study different types of OCS makes generalization difficult. (Wiki, Open science, Open source, etc.) For example, papers that discuss the nature of Wikipedia seldom reference and integrate related work studying open source software or other crowdsourced projects. This has resulted in silos of proto-theory that are ripe for tearing down.

Theory-based research on OCSs should allow for comparative analysis and integration of findings across work contexts/communities/platforms. We identified three key areas of concern that would benefit immediately from more multidisciplinary, theory-driven research:

How can we socialize new volunteers in mature, complex OCSs?
With increasing norm complexity, it seems that this open socialization pattern stops working so well.[1][2] Attempts at formalizing mentor/mentee relationships have been unsuccessful -- largely due to the small scale at which the project operated and due to the difficulty of entrance for mentees. .[3] Experiments in introducing new means of socialization support have shown promise qualitatively, but improvements on newcomer retention have not been experimentally demonstrated.[4][5][6]
How can we make software changes without disrupting work practices?
Recently managers of OCSs have struggled to deploy improvements to mature OCS without causing substantial disruptions. For example, nearly every major software change that the Wikimedia Foundation has deployed to large, mature Wikipedia communities has been surrounded in conflict that pits the “staff” vs. the “volunteers” (e.g. new contribution mechanisms[1], WYSIWYG editor[2] and new media viewer[3]). Recent literature suggests that this is not a phenomenon that is limited to wiki medium (e.g. [7]). The CSCW literature has a celebrated history of calling attention to invisible infrastructures of socio-technical work practice[8], but there’s a lack of practical advice for managers of mature OCSs. Is there a way that software changes can be designed, developed and deployed in a way that minimizes this disruption?
What is a “normal” life-cycle for an OCS?
English Wikipedia is arguably the largest, mature, online open collaboration projects that has been studied in the CSCW literature. Recent work has explored declining trends in the community’s volunteer population[9] that seem to have been caused by increasing rule complexity and the need for efficient quality control processes[2]. While it’s clear that this trend has lead to decreased productivity, it’s not clear whether this is “normal” or even “healthy” for an OCS of this scale. If such declines in participation are undesirable, what strategies will allow the communities to recover? Addressing these questions is of critical importance to both the maintainers and community leaders of large scale OCS.

Comparative analysis[edit]

Performing comparative analysis between OCSs is difficult for many reasons, including incompatible data formats, inconsistent access to data, and incongruent metrics for activity, quality, contribution, etc. Most research studies focus on a single site, at a single point in time. This has lead to a lack of generalization: while some work has found evidence for ‘strong regularities’ in participation, but it is not clear, for instance, how to compare the work of power users in creating and curating WikiHow manuals and StackExchange Question threads.

Practical considerations govern many academic researchers’ decisions of which OCS to study. A large portion of academic work to date uses data from English Wikipedia because the data is open and the WMF hosts individuals who can act as liaisons. While Wikipedia is a rich and multifaceted data source, this focus on Wikipedia likely colors our understanding of OCSs generally. It is not clear, for example, whether Wikipedia’s exponential growth trajectory, followed by an extended plateau in participation, is characteristic of OCSs in general. This may be preventing advancement of the field and leading to ill-advised design decisions or misleading conclusions when dealing with other (smaller, non-wiki, differently-focused) OCS projects.

Further, many studies draw from a single theoretical framework, using one type of methodology or analysing an OCS at only one level. The tendency is understandable given the distribution of OCS researchers across myriad disciplines and departments, and the depth of expertise required to perform rigorous, theory-driven research. However, it has resulted in a lack of integrated theories about the nature of OCS and the siloing of the literature into different journals and conference proceedings.

Finally, “least publishable unit” approach to research, common in fields like HCI, encourages the proliferation of one off studies that limit their scope to a single moment in the lifespan of OCSs, rather than longitudinal studies focused on temporal shifts, trends, and cycles of activity.

To address these challenges, we call for an ecological approach to OCS research that examines systems across multiple dimensions.

comparison across time
More longitudinal research is required in order to increase our understanding of the trajectories, shifts, and cycles of activity over the lifespan of an OCS.
comparison across OCSs
More comparative research is required in order to increase our understanding of the influence of factors such as the size of a system, the type of work, and community dynamics on the character of an OCS. One underdeveloped area of research that we consider to be particularly important is analysis of what constitutes success and failure in different OCSs.
comparison across theories and epistemologies
In order to develop a coherent body of theory around open collaboration, we must understand the advantages and drawbacks of applying theoretical frameworks that were developed elsewhere. This involves critically assessing the suitability of theories and metaphors borrowed from other domains of science, such as biological ecology, organization science, and economics for OCS research. It will also be necessary to assessing the commensurability of findings from theory-driven studies with different epistemological bases (for example positivism vs. interpretivism).
comparison between levels of analysis
Open collaborations are complex socio-technical systems. Understanding these systems involves examining individual components (people, software features), aggregates (communities, platforms), as well as the interactions between the system and its context--the cultures, institutions, and infrastructures with which the system and its human participants are embedded. Comparing the explanatory power of theories that work at different levels of analysis (for example theories of individual motivation vs. social interaction vs. system dynamics), and evaluating the compatibility of research methods that operate at different analytical levels is of critical importance.

We recognize that current incentive structures for OCS researchers and practitioners often conspire against open data access, interdisciplinary research, and generalizability and reproducibility of research findings.

However, incremental progress can be made. Other organizations can learn from the Wikimedia Foundation’s model of releasing regular, open licensed database dumps and providing access to a full history via a live API. This strategy has encouraged many researchers to study Wikimedia Projects, and resulted in a wealth of actionable research findings, novel methods for data analysis, and innovative design prototypes.

Conferences and journals that seek to publish high quality OCS research can also learn from venues that have adopted more open approaches to review and access. Public Library of Science (PLOS) has been a pioneer in open access, with a review process that focuses on methodological rigor rather than disciplinary conformity. By doing away with explicit page limits and instituting a staged review process, the ACM Computer Supported Cooperative Work conference (CSCW) has demonstrated that it is possible to maintain high quality standards and a relatively high (~30%) acceptance rate while relaxing arbitrary constraints around the size of publishable “unit” of research.

Shared research infrastructure[edit]

Shared infrastructure for Open Collaboration Systems research is necessary now for a number of reasons, all of which center on a) leverage advantages of shared infrastructure, and b) intellectual cohesiveness advantages of shared infrastructure.

Both leverage and cohesiveness across disciplines are enabled by a shared infrastructure because OOCs are fundamentally distinct networking and collaboration phenomena that facilitate the collective construction of tangible or intangible products using flexible, distributed, and non-hierarchical forms of organization. The emergence of widely available, highly flexible, interactive information infrastructure technologies significantly altered the universe of feasible organization structures and strategies. OOCs represent a new class of organizing solutions, in which individuals self-organize in order to collaboratively produce any number of artifacts and experiences. OOCs differ from other popular online structures, such as crowdsourcing platforms or online social networks in significant ways. In crowdsourcing, the firm or client proposing the project typically controls the decision-making process. In online social networks, organized collective production is not usually a goal for participants. The evolution and potential of OOC structures and processes creates a need for the type of interdisciplinary community building proposed. OOCs now play a critical role across the many domains of society.

Developing a more coherent understanding of OOC’s through the development across datasets would further multiple intellectual disciplines, and yield economic, health and educational benefits for societies that are becoming more technologically mediated. A community of scholars dedicated to a more coherent unpacking of the success patterns, failure patterns and factors affecting growth and performance in OOCs will make concrete contributions to businesses, governments, and citizens. The current diffuseness of OOC research makes discipline specific findings difficult for society to utilize because most organizations lack the incentives, time, and capacity to parse and prioritize each scientific discipline’s unique perspective on OOCs. Presently, OOC researchers often lack the incentives, knowledge, and capacity to create truly sharable data resources. This communication and coherence gap around knowledge construction in OOCs limits the impact of OOC research and development. This proposed project is a first, but important step toward building a community that overcomes existing obstacles.

This workshop proposal intends to advance the efforts to build interdisciplinary understanding of how to execute OOC research collaboratively, across communities and builds on one of the core aims of the OCDF virtual institute.

  • Comparative analysis and better cross-divide collaboration can be supported by centralized infrastructure.
    • Infrastructure: Dataset storage, Q&A, documentation, indexes, community, etc.
  • To create and maintain such an infrastructure, we will active participation by members of OCS enterprise and academic research communities both. There must be incentives for both sides to develop, maintain, and participate:
    • Industry: Industrial research liaison (force multiplier) -- Someone with the mandate to support external researchers -- maximize value of research community to industrial orgs.
    • Academic: formalize participation as “service work” -- develop relationships & community → advancement of the field
  • Use an open research community space to outsource industrial research liaison work
    • Works for Wikimedia (mailing list and IRC populated by many people who can answer questions -- most of whom are not staff)
    • it may be easier to join existing OCSs built around topic-focused, social Q&A, such as, than to try to create and maintain an entirely new forum.


  • We also identified strategies that can be used while infrastructure is in development:
    • Omnibus survey & cross-community surveys
      • Surveys perform many roles for community and researchers -- work together on common questions (cite social science survey thingie)
    • collaboration on projects/grant proposals
      • HOWEVER… Direct collaboration between industry and academia is difficult due to mismatched timescales of organizational needs, grants and open-ended work.
      • If academics and industry practitioners are aligned on problems/needs, then they should take advantage of the opportunity to work together.
      • In these cases, it’s easier to justify engineering and research support for academics and write that support into grant proposals.

Next steps[edit]

In this section, we describe the immediate next steps participants of the workshop and other OCS research should take. We’ve grouped the items by who should be responsible for implementing them: industry practitioners, academics or both in collaboration.

Industry practitioners[edit]

‘’’Formal recognition of research support’’’ Industry organizations can reap substantial benefits from external researchers. Spending even a small amount of resources on research support can lead to substantial value. For example mailing lists like wiki-research-l[10] and DERP proposals[11] have developed communities that provide a routing service to help researchers find datasets and related work around a platform. These lists can be developed and supported by a single person or small group of people part-time. Advocate for formal recognition of research liaison and advisory roles & responsibilities within your organization. ‘’’Release your data’’’ Make data available in ways that researchers need. This means releasing historical datasets and publishing APIs that make historical analysis possible. ‘’’Document for an academic audience’’’ Researchers will be more likely to study your community if your resources are well documented. Document your data sources, your processes/policies, and your “big questions” for researchers to reference in papers and grant proposals.


‘’’Write for an industry audience’’’ Make your research findings available to relevant industry practitioners and articulate their relevance to immediate problems that organizations face. ‘’’Formal recognition for collaboration’’’ Academic fields stand to benefit from improved collaboration between industry and academic. While this means the work ought to qualify as service work, it doesn’t fit into the current models. New models of service work will need to be developed around supporting collaborative research/data infrastructure maintenance. ‘’’Leverage your relationship with an OCS’’’ Approach OCS orgs with funding collaboration opportunities (e.g., NSF grants). While industry practitioners may not need the grant’s funding they may be willing to endorse and otherwise support projects that align with their goals.

Both in collaboration[edit]

‘’’Cross-community studies and grant proposals’’’ Gather researchers who have built expertise in different communities/datasets to study common phenomena (e.g. This is a temporary solution to the lack of shared technical infrastructure and common documentation. ‘’’Collaborate on shared infrastructure’’’ Both academics and industry researchers benefit from better platforms for sharing research proposals, datasets and results. Define roles and share responsibilities for the maintenance of this infrastructure. Use this platform to develop standard dataset/API formats and prototypical datasets.


While this workshop allowed us to come together, strengthen our community and start a call for new work in access and theoretical development, there’s still much work that will need to be coordinated. Future workshops should either focus directly addressing one of the next steps called out above (e.g. collaborating on shared infrastructure) or produce an expanded set of concrete next steps.
