How Do Library Consultants Assess Library Performance?
The Visual Scan in Practice
Talk to a Consultant
TL;DR
What You Need to Know
Library consultants assess performance through structured, stakeholder-facilitated walkthroughs that reveal how patrons actually use space, not how planners assumed they would. The Visual Scan translates observable behaviors, seating patterns, and service adjacencies into quantifiable programming evidence that supports renovation, reorganization, and capital decisions. Findings from a Visual Scan connect directly to space priorities, bond campaign justification, and adjacency planning that serve a community for decades.
The Director Who Knew Something Was Wrong
A library director at a mid-sized regional university calls us. Not because the facility is failing in any obvious way. Gate counts are steady, staff are conscientious, and the catalog is current. She calls because something feels off every time she walks through the building. The twelve carrels designated for individual quiet study are perpetually empty, while three mismatched armchairs near the north-facing windows are perpetually full. Students cluster at tables closest to the circulation desk, apparently seeking proximity to the service point even when they have not asked a question. The third floor, which once housed a busy reference collection relocated to storage three years ago, now functions as an improvised lounge. Nobody planned it that way.
She is not wrong that something is off. She is simply working without a methodology for reading what she is seeing. What looks like spatial drift is actually a legible message. Patrons are telling her, through their bodies and their choices, exactly which parts of the building are working and which are not. The armchairs at the windows are telling her that natural light and soft seating near a low-noise zone serve a real need. The cluster at the circulation desk is telling her that the reference function has migrated toward the entry rather than remaining anchored at a remote desk. The improvised third-floor lounge is telling her that informal social learning is underserved and that people will create what they need if the institution does not.
Reading that message accurately, systematically, and in enough depth to justify a capital investment is precisely what the Visual Scan is designed to do. It is not a tour. It is structured assessment grounded in behavioral observation, facilitated with the community members who carry the local knowledge administrators cannot always see, and translated directly into the spatial and service recommendations that drive renovation programming, organizational realignment, and capital requests.
Why Observation Is the Foundation of Library Performance Assessment
When library directors ask how consultants assess library performance, they often expect an answer built around surveys, usage statistics, and peer benchmarking. These tools have value. They do not have primacy. The most reliable evidence of whether a facility is performing is the behavior of the people inside it. Surveys capture aspirations and complaints after the fact. Observation captures reality in real time.
Research published in Library and Information Science Research by Given and Archibald documents what practitioners have known for decades: patrons persistently use spaces differently than planners intended. In a large urban university business library, patrons gravitated to specific zones for laptop use despite the library having designated entirely different areas for that purpose. The mismatch between design intent and observed behavior was not visible in any survey or circulation record. It was visible only when someone systematically looked at where people actually sat and what they actually did.
The ethnographic literature on library study behavior adds another dimension. A study conducted at Brock University documented what the researcher called an ebb and flow to library use: students working individually, migrating into groups, then returning to solitary work, often within a single sitting. This behavioral rhythm demands spatial flexibility rather than rigid zone designations, yet most libraries are planned around fixed categories of use. The honest assessment reveals that the categories frequently serve the institution's organizational logic more than the patron's cognitive workflow.
A further complication is that absence is as informative as presence. The consultant trained in structured observation watches for the patron who does not appear: the graduate student who needs a long, undisturbed table with a power source and a quiet neighbor and leaves within ten minutes because no such configuration exists. The community member who needs a semi-private space for a sensitive information consultation but finds only open tables in full view of the entry. These unmet needs do not register in gate counts or satisfaction surveys. They register only in observation informed by a deep understanding of what a library can and should be. For what a library consultant does at the highest level of practice, reading absence is as essential a skill as reading presence.
- Observation reveals the gap between designed intent and actual use, which surveys cannot capture.
- Patron behavior is spatial: where people sit, move, and cluster is as telling as what they say about the library.
- Absence of expected users in a zone signals unmet need, not contentment with the status quo.
- Behavioral patterns repeat across time, making them reliable evidence for capital and programming decisions.
What the Visual Scan Reveals: Reading the Spatial Narrative
The Visual Scan is a structured, facilitated walkthrough of the library environment conducted with community members and key stakeholders. It is the methodology through which Aaron Cohen Associates translates observable patron behavior into the spatial and service evidence that drives design solutions across every library type we serve, from academic and public institutions to law firms, medical centers, corporate research environments, government libraries, archives, and special collections. The scan is not a single pass through the building. It is a time-stratified observational exercise conducted at different hours and across multiple days, because the library serves different populations at nine in the morning, at noon, and at seven in the evening, and those populations behave differently.
The primary data the scan collects falls into several categories. Seating utilization patterns document which seats are occupied, which are perpetually empty, and which have been physically rearranged by patrons to suit needs the original layout did not anticipate. Traffic flow and navigation paths reveal which routes patrons actually take through the building, often quite different from the circulation sequence the architect intended. Service desk adjacency relationships show whether reference, circulation, and technology help functions are positioned close enough to the patron concentrations they are meant to serve. Collection access patterns indicate whether shelving locations are generating active browsing or whether whole ranges of the collection have become effectively invisible.
Environmental signals matter as much as behavioral ones. Lighting quality influences the distribution of individual study. Noise gradients determine where focused cognitive work is possible and where it is not. Furniture scale and arrangement signal to patrons whether a space is welcoming or institutional, collaborative or solitary. Ethnographic observation at Brock University found that dimly lit areas produced more resting behavior while brightly lit areas produced more engagement and social activity, a finding with direct implications for positioning quiet study away from high-brightness entry and service areas.
One of the most instructive insights the Visual Scan produces comes from what researchers at Purdue University discovered when they assessed their Wilmeth Active Learning Center, a 179,000-square-foot facility that integrated library space with active learning classrooms. When active learning classrooms were placed adjacent to collaborative library space, students arrived before class, stayed after, and drew their instructors into the library alongside them. Instructors began holding office hours in the library because that was where their students already were. The practical effect was that the building's active use extended across a dramatically longer daily span than a conventional library arrangement would produce. Adjacency created behavioral possibility that no programming announcement could have achieved. This is the central principle the Visual Scan is designed to surface: the spatial relationships between functions determine what the library makes possible for the people it serves.
The scan also surfaces service configuration problems that are invisible from behind a desk. A reference desk positioned at the far end of a long building requires patrons to walk past every alternative before reaching help, and most will not make that journey. A technology cluster placed adjacent to a quiet reading room creates noise conflict that gradually empties both zones. These patterns are invisible in a usage report and fully legible in a well-conducted walkthrough. They translate directly into the adjacency planning and strategic library development that guide enduring institutional investment.
- Seating utilization, traffic flow, service adjacency, collection access, and environmental signals are the primary observation categories.
- Observations must span multiple times of day and days of the week to capture the full behavioral range of the library's community.
- Patron rearrangement of furniture is evidence, not violation: it shows what configuration the space needs to provide.
- Adjacency between functions determines behavioral possibility, as demonstrated in active learning center research at Purdue University.
- Environmental factors including lighting, noise gradients, and furniture scale shape patron distribution in measurable, plannable ways.
Core Observational Competencies
What the Visual Scan Measures
Each competency below represents a distinct observational discipline that Aaron Cohen Associates applies systematically during every Visual Scan engagement. Together they convert raw behavioral observation into defensible programming evidence for renovation, reorganization, and capital investment decisions.
Documenting which seats are occupied, perpetually empty, or physically rearranged by patrons to reveal the gap between designed intent and actual spatial need.
Tracing the routes patrons actually take through the building, often diverging significantly from the circulation sequence the architect intended, to identify friction points and missed adjacencies.
Assessing lighting quality, noise gradients, furniture scale, and sight lines to understand how physical conditions shape patron distribution in ways the space plan did not intend.
Structuring the walkthrough group to surface distributed institutional knowledge from frontline staff, community users, subject experts, and facilities personnel simultaneously without premature consensus.
The Stakeholder Dimension: Why Facilitation Multiplies Insight
The Visual Scan is a facilitated exercise, not a solo inspection. This distinction matters more than it might appear. An administrator walking through a library sees it through a lens shaped by organizational responsibility, institutional memory, and the assumptions that accumulate from knowing a space very well. A consultant walking alone sees it through a professional lens trained by hundreds of prior assessments but necessarily lacking the local knowledge that only community members carry. Neither perspective alone produces reliable programming evidence. The combination does.
Van House and colleagues, writing foundationally in the library assessment literature, emphasized the effectiveness of collaborative efforts in measuring library service quality. Their argument applies with full force to facility assessment: involving diverse stakeholders surfaces distributed knowledge that no individual possesses. A frontline circulation staff member knows exactly where the heaviest patron traffic creates bottlenecks during the morning rush. A subject librarian knows which collection areas generate genuine browsing versus directed retrieval. A student knows which furniture becomes physically uncomfortable after ninety minutes of study. A faculty member knows which spatial configurations discourage the collaborative work their assignments require. A facilities manager knows where the mechanical systems create noise problems the staff have long since stopped noticing.
Structured facilitation during the scan means organizing the walkthrough so that each participant's perspective is captured without group dynamics converging prematurely on consensus. The most valuable data often comes from disagreement: when a department head sees a thriving group study zone and a reference librarian sees the same space as a place where patrons regularly abandon research without resolution, both observations are correct and both are informative. One researcher studying student behavior in a library documented how his own initial bias led him to avoid observing a noisy group study area he had mentally categorized as unproductive, only to discover upon entering it that it contained the richest behavioral data in the building. Structured facilitation is designed precisely to prevent that error from compressing the evidence before it can be evaluated.
Across the library types we serve, the stakeholder composition changes but the principle holds constant. In a law library, the walkthrough group should include senior attorneys, associate researchers, and paralegal staff, because each tier uses the collection and space differently and each tier's workflow has distinct spatial implications. In a public library, a community member who depends on the library for job search resources sees adjacency problems that professional staff simply do not notice. In a corporate research environment, a product development team member can identify where the physical arrangement of information resources creates friction in a workflow that moves between the library and the research floor. In a medical library serving both clinical and academic staff, the distinction between quick reference lookup and sustained literature review demands spatial separation that only mixed-stakeholder observation will reveal. The Visual Scan is the structured mechanism for collecting all of that distributed intelligence and converting it into spatial evidence that a board, a donor, or a bond committee can act upon.
- Diverse stakeholder groups surface distributed knowledge that administrator or consultant observation alone cannot access.
- Structured facilitation prevents premature consensus and preserves the evidential value of disagreement between observer perspectives.
- Frontline staff, community users, subject experts, and facilities personnel each see different aspects of facility performance.
- Stakeholder composition should reflect the actual user population, varying by library type and institutional context.
- The facilitated walk builds institutional buy-in for recommendations because stakeholders have seen the evidence themselves.
The Visual Scan Protocol: Six Steps from Threshold to Recommendation
The Visual Scan is not a casual walk-through. It is a structured assessment protocol with discrete phases, each of which feeds the next. Applied consistently across library types and sizes, from a 5,000-square-foot special collections reading room to a 200,000-square-foot academic research complex, this sequence transforms observable patron behavior into defensible programming evidence. Here is how consultants execute it.
Step 1: Brief and Scope
Before anyone enters the building, define the assessment purpose: is this a renovation programming exercise, a capital justification effort, an organizational realignment, or a service planning initiative? The purpose determines which observation categories matter most. Establish a standard notation scheme for the walkthrough so that findings from multiple observers can be directly compared. Identify which time periods across the week will be covered and which zones of the building require particular attention based on known concerns. Share background data with participants in advance: recent gate counts, room reservation rates, reference transaction trends, and any prior survey results. The scan will interpret behavioral evidence; prior data provides the context for intelligent interpretation.
Step 2: Stakeholder Assembly
Constitute the walking group for diversity, not consensus. The goal is a range of perspectives that covers the full spectrum of library use. At minimum, include frontline staff from at least two different service points, two or three community members who represent different user groups, facilities personnel who know the building's physical systems, and the library director or a senior administrator. For academic libraries, include at least one faculty member and one student. For public libraries, include a board member and a regular patron from a demographic group the current configuration tends to underserve. For law, medical, corporate, or government libraries, include representatives from the professional staff who have the most demanding information workflows. Limit the total group to six to eight participants. Larger groups disrupt the space being observed and produce unwieldy debrief sessions.
Step 3: Time-Stratified Observation
Conduct the walkthrough at least three times across the same week, distributed across morning, midday, and peak evening hours. Do not average these sessions into a single composite picture. The morning population at an academic library is typically a different group pursuing different tasks than the evening population, and the building's performance for each must be assessed independently. For public libraries, weekend observations capture a family and community use pattern that is absent on Tuesday morning. For a corporate or law library, peak usage may be tied to client deadlines or court schedules rather than time of day. Document the time and day of every observation on every annotation sheet, because temporal context is essential for interpreting what you see.
Step 4: Annotated Floor Plan Documentation
Equip each participant with a printed floor plan at sufficient scale to support readable notations. Use a simple, pre-established notation key: seat occupancy codes such as occupied, available, and patron-rearranged; activity type indicators such as individual study, group work, active device use, social interaction, and transit; and environmental signal notes covering noise level on a three-point scale, lighting quality, furniture condition, and visible wayfinding problems. Encourage brief narrative annotations in the margins for observations the code cannot capture. The annotated floor plan is the primary deliverable of each observation session and must be specific enough to locate behavioral patterns precisely within the building. For large or multi-floor facilities, consider assigning different observers to different zones to achieve simultaneous coverage.
Step 5: Group Debrief and Pattern Synthesis
Within twenty-four hours of each observation session, convene the group for a structured debrief of no more than ninety minutes. Post the annotated floor plans from all participants and use them as a shared reference. Work through each major zone of the building systematically, asking participants to report what they observed without editorializing. Note agreements, which confirm reliable patterns, and disagreements, which often reveal the most instructive findings. A space that one observer read as underused and another observed as consistently repurposed is a space communicating a service gap. Record the debrief findings in a consolidated zone-by-zone summary that preserves both the observed pattern and the interpretive reasoning applied to it.
Step 6: Programming Translation
The final step converts observational synthesis into actionable spatial and service implications. For each major finding, ask: what spatial change would resolve this friction or honor this evident need? Which adjacencies should be maintained, which should be dissolved, and which new adjacencies would unlock behavioral possibility that the current layout prevents? Where does the evidence support expanding a function, and where does it support contracting one? These findings become the evidentiary foundation for capital planning and bond campaign development, space programming narratives, phased renovation sequences, and service reorganization plans. At Aaron Cohen Associates, Visual Scan findings are always connected directly to specific square footage allocations, seating configurations, and service positioning recommendations, because evidence that does not reach a decision is evidence wasted.
Library Environments We Assess
Putting It into Practice
What to Do
- Conduct observations at multiple times of day and across multiple days before drawing any conclusions. A single session produces a snapshot, not a pattern.
- Use a standardized notation scheme so findings from different observers are directly comparable in the debrief and synthesis phases.
- Include frontline staff and community members alongside administrators. Distributed institutional knowledge is the most valuable asset the Visual Scan collects.
- Triangulate what you observe with quantitative data: gate counts, room reservation records, technology loan logs, and reference transaction trends provide the numerical context that gives behavioral findings their scale and defensibility.
- Document the spatial location of every observed behavior, not just the behavior itself. Where something happens is as informative as what happens.
- Follow the scan with targeted patron interviews or brief surveys to answer the why questions that observation alone cannot resolve.
- Conduct the Visual Scan across different seasons or academic periods when the patron population shifts significantly. A library that performs well in October may reveal different strengths and weaknesses in January.
- Connect every observational finding to a specific spatial or service recommendation. Assessment without programming translation is an incomplete exercise.
What to Avoid
- Conducting the walkthrough with only library leadership present. Administrative perspective alone introduces systematic blind spots that are precisely the most consequential ones.
- Drawing conclusions from a single observation at a single time of day. Patron populations and behaviors vary enough across the week that any single session is misleading.
- Treating patron repurposing of designated spaces as a problem to be corrected rather than as evidence to be understood. When patrons persistently use a space differently than designed, they are providing reliable programming data.
- Allowing group conversations during the observation itself. Discussion during the walk contaminates the behavioral environment being studied and introduces post-hoc rationalization into real-time data collection.
- Separating the observation phase from the programming phase. A walkthrough that does not feed directly into spatial recommendations or service reconfiguration decisions leaves evidence unused.
- Relying solely on staff opinion of how patrons use the space. Staff perspectives are valuable but systematically filtered by role, location, and familiarity with the building.
- Ignoring environmental variables such as lighting, temperature, noise gradients, and furniture scale. These factors shape patron distribution in measurable ways and frequently explain behavioral patterns that otherwise appear random or inexplicable.
Questions to Ask During the Visual Scan
These diagnostic questions structure the debrief conversation and ensure that observational data is converted into spatial and service insight rather than anecdote. Each question is designed to surface a specific category of facility performance evidence.
- Where are patrons consistently ignoring designated seating and gathering in other locations, and what does that substitution reveal about what the designated area lacks?
- Which service points do patrons approach, and from which directions? Does the furniture arrangement and traffic flow support those approach paths, or create friction between patron intent and spatial reality?
- Where is the noise gradient misaligned with the patron mix? Are quiet carrels adjacent to high-traffic corridors, or are group study zones immediately beside individual reading areas?
- What behaviors are occurring in spaces not designed for them, and what unmet need does that improvisation signal?
- Are collection adjacencies serving active research workflows, or are they artifacts of historical shelving decisions that no longer correspond to how patrons actually work?
- Where do patrons appear to abandon their purpose and leave, and what were they most likely looking for when they arrived?
- How does the positioning of staff correspond to the concentration of patrons? Are the highest-need zones the most physically accessible to frontline service personnel?
- What environmental factors, including lighting, temperature, sight lines, and furniture scale, are shaping patron distribution in ways the space plan did not intend and the library has not yet recognized?
