“We’ve always done it this way” is not evidence.

How do you know whether a wayfinding system, user journey or environment will work before people have to rely on it?

For decades, much of wayfinding and user experience design has relied on professional judgement, accepted standards and precedent. These remain valuable, but they also carry assumptions. A solution may be familiar to the design team while remaining unclear to someone encountering the environment for the first time.

The consequences often become visible only after implementation. People miss decision points, interpret information differently than expected, hesitate at important transitions or ask staff for directions. By then, resolving the problem can involve retrofitting signs, changing information systems or accepting an ongoing operational burden.

Testing provides an opportunity to find these problems earlier.

Moving from assumptions to evidence

Evidence-based design requires more than asking users whether they like a proposal. It means observing how people understand information, make decisions and complete realistic tasks.

This can begin with an existing environment. Audits and gap analysis establish how the physical setting, wayfinding, information and operational processes work together. They reveal where journeys are well supported, where friction occurs and where gaps between individual systems create confusion.

Observation and user feedback add another layer. They help explain how people respond to the environment in practice, including the workarounds they develop and the points at which they need assistance.

Proposed environments can also be evaluated before construction. Virtual simulations allow participants to undertake representative journeys and tasks within a realistic version of the design. This makes it possible to examine wayfinding strategies, spatial clarity, information systems and critical decision points while there is still time to respond.

Eye-tracking can provide further insight into what participants notice, overlook or misunderstand. Combined with observation, participant feedback and spatial analysis, it helps reveal what is happening and why.

Testing the complete experience

Wayfinding performance cannot be understood by looking at signs in isolation. People use architecture, landmarks, lighting, sightlines, terminology, digital information and cues from other people to understand where they are and what to do next.

Their responses are also influenced by familiarity, ability, language, cognitive load, time pressure and emotional state. A system that appears logical under ideal conditions may perform very differently when someone is unfamiliar with the place, distracted, anxious or in a hurry.

Effective evaluation therefore considers the complete experience. Depending on the question, testing may focus on a single decision point, an information interface, a complete journey through a building or precinct, or the interaction between physical, digital and service systems.

Introducing HumanReady

HumanReady is Humanics Collective’s methodology for testing and evaluating wayfinding systems, user journeys and complex environments.

It brings together audits, gap analysis, behavioural observation and testing in virtual environments. The methodology can be applied to existing places, proposed designs or both, allowing findings from current performance to inform future decisions.

Testing can also be iterative. A design is evaluated, the findings inform changes, and the revised solution is tested again. This provides evidence that an intervention has improved performance rather than simply changed its appearance.

Better evidence supports better decisions

Testing cannot remove every uncertainty from a project. It can expose assumptions, identify avoidable problems and give project teams a clearer basis for deciding where changes and investment will have the greatest effect.

It also creates a shared evidence base when stakeholders hold different views. Discussions can move beyond individual preference towards observed behaviour and measurable performance.

Professional experience will always play an important role in design. HumanReady strengthens that experience by testing its assumptions against the people and situations the environment needs to support.

Because “we’ve always done it this way” explains the past. It does not prove that the design will work.
