The process used to research and create the NMC Horizon Report: 2015 Library Edition is very much rooted in the methods used throughout the Horizon Project. All editions of the NMC Horizon Report are produced using a carefully constructed process that is informed by both primary and secondary research. Dozens of technologies, meaningful trends, and critical challenges are examined for possible inclusion in the report for each edition. Every report draws on the considerable expertise of an internationally renowned Panel of Experts that first considers a broad set of important emerging technologies, challenges, and trends, and then examines each of them in progressively more detail, reducing the set until the final listing of technologies, trends, and challenges is selected.

Much of the process takes place online, where it is captured and placed in a the Horizon Project wiki, where all the work of the project makes its home on the web. The Horizon Project wiki is intended to be a completely transparent window to the all of the work of the project, and contains the entire record of the research for all the various editions.

The procedure for selecting the topics that will be in the report includes a modified Delphi process now refined over years of producing Horizon Reports, and it begins with the assembly of the Panel of Experts. The panel as a whole is intended to represent a wide range of backgrounds, nationalities, and interests, yet each member brings a particularly relevant expertise. To date, hundreds of internationally recognized practitioners and experts have participated in the Horizon Project Panel of Experts; in any given year, a third of Panel of Experts are new, ensuring a flow of fresh perspectives each year.

Once the Panel of Experts for a particular edition is constituted, their work begins with a systematic review of the literature — press clippings, reports, essays, and other materials — that pertains to emerging technology. Panel of Experts are provided with an extensive set of background materials when the project begins, and are then asked to comment on them, identify those that seem especially worthwhile, and add to the set. The group discusses existing applications of emerging technology and brainstorms new ones. A key criterion for the inclusion of a topic is the potential relevance of the topic to teaching, learning, research, or creative expression. A carefully selected set of RSS feeds from dozens of relevant publications ensures that background resources stay current as the project progresses. They are used to inform the thinking of the participants throughout the process.

Following the review of the literature, the Panel of Experts engaged in the central focus of the research — the research questions that are at the core of the Horizon Project. These questions were designed to elicit a comprehensive listing of interesting technologies, challenges, and trends from the Advisory Board:

    1. Which of the important developments in educational technology catalogued in the Horizon Project Listing will be most important to academic and research in libraries within the next five years?
      1. What would you list among the established developments in technology that some libraries are using today that arguably ALL libraries should be using broadly?
      2. What developments in technology that have a solid user base in consumer, entertainment, or other industries should libraries be actively looking for ways to apply?
      3. What are the key emerging technologies you see developing to the point that libraries should begin to take notice during the next four to five years?
    2. What key trends do you expect to accelerate technology adoption for academic and research libraries?
    3. What do you see as the significant challenges impeding technology adoption for academic and research libraries during the next five years?

One of the Panel of Expert’s most important tasks is to answer these questions as systematically and broadly as possible, so as to ensure that the range of relevant topics is considered. Once this work is done, a process that moves quickly over just a few days, the Panel of Experts moves to a unique consensus-building process based on an iterative Delphi-based methodology.

In the first step of this approach, the responses to the research questions are systematically ranked and placed into adoption horizons by each Panel of Experts using a multi-vote system that allows members to weight their selections. Each panelist is asked to also identify the timeframe during which they feel the technology would enter mainstream use — defined for the purpose of the project as about 20% of institutions adopting it within the period discussed. (This figure is based on the research of Geoffrey A. Moore and refers to the critical mass of adoptions needed for a technology to have a chance of entering broad use.) These rankings are compiled into a collective set of responses, and inevitably, the ones around which there is the most agreement are quickly apparent.

From the comprehensive list of technologies originally considered for any report, the twelve that emerge at the top of the initial ranking process — four per adoption horizon — are summarized. Once this “short list” is identified, the group, working with both NMC staff and practitioners in the field, begins to explore the ways in which these twelve important technologies might be used in academic and research libraries. A significant amount of time is spent researching real and potential applications for each of the areas that would be of interest to policy-makers, leaders, and practitioners.

For every edition, when that work is done, the interim results are written up. With this information, the “short list” is then ranked yet again, this time in reverse. The six trends, six challenges, and six developments in technology that emerge are those detailed in the NMC Horizon Report: 2015 Library Edition.
