Define routes, zones and points of interest
Indoor navigation systems attract interest because they promise to solve a visible problem: people getting lost, asking staff for directions, or missing parts of a venue. Before committing budget and operational effort to any technology, the practical question is whether the problem is severe enough, frequent enough, and costly enough to justify a solution that itself requires ongoing maintenance.
Assessment at this stage is not about choosing between Bluetooth beacons, Wi-Fi positioning, or other signal sources. It is about establishing whether a location-based wayfinding system is the correct intervention at all, or whether simpler alternatives — better signage, revised floor plans, staff positioning — would address the same issue with less complexity.
A useful assessment starts with observed behaviour rather than assumed demand. Complaints about finding things, measurable dwell times in corridors, staff time spent giving directions, and visitor exit surveys all provide evidence. Without that evidence, a navigation project risks solving a problem that is minor or hypothetical.
The assessment also needs to distinguish between different types of wayfinding need. A large hospital where patients must reach specific departments within a time window faces a different problem from a museum where visitors wander at their own pace and may simply want to know what is nearby. The technology requirements, accuracy expectations, and failure consequences vary considerably between those scenarios.
Field verification and route modelling
Venues where indoor navigation commonly earns its place
Large, complex buildings with multiple floors, repeating layouts, or zones that look similar from the inside are the strongest candidates. Transport hubs, hospital campuses, conference centres, and large retail stores fit this pattern. In these environments, visitors genuinely cannot rely on visual landmarks alone, and wrong turns have a measurable cost — missed appointments, delayed departures, or abandoned purchases.
Museums and galleries present a different but legitimate case. Here the need is not usually about reaching a destination urgently but about ensuring visitors can find exhibits they want to see, follow a recommended route, or locate facilities. The value is measured in visit completeness and satisfaction rather than time saved.
Events and temporary venues can justify navigation when the layout changes frequently, visitors are unfamiliar with the site, and peak periods make staff assistance impractical. However, the temporary nature of the infrastructure introduces its own constraints, which are covered in the event wayfinding material elsewhere on this site.
Signs that suggest a genuine need
- Staff regularly report that giving directions occupies a significant portion of their working time, particularly at entry points and junctions.
- Visitor feedback, complaints, or survey responses repeatedly mention difficulty finding specific areas or facilities.
- Analytics or observation show that certain zones receive far less traffic than their function or content would suggest, indicating visitors are not reaching them.
- The building has multiple floors, a non-linear layout, or sections that are visually indistinct from one another.
- There are time-sensitive use cases, such as catching a connection or attending a scheduled session, where getting lost has a concrete consequence.
Signs that suggest indoor navigation may be unnecessary
- The building is essentially a single open floor plan where line of sight or simple overhead signage resolves most queries.
- Visitor flows are predictable and well-managed by existing physical wayfinding.
- The venue is small enough that most visitors orient themselves within a minute or two of entry.
- Staff are already positioned at natural decision points and can direct people without disruption to their other duties.
- The perceived problem is based on a few anecdotal complaints rather than observed patterns.
Keep routes accurate after building changes
Overestimating the problem
One of the most frequent errors is treating every "where is..." question as evidence that a technology system is required. In many venues, a modest investment in refreshed physical signage, floor markings, or better placement of information boards eliminates the majority of directional confusion. Indoor navigation should be considered only after simpler interventions have been evaluated and found insufficient for the scale of the problem.
Confusing navigation with content delivery
Some projects begin as a desire to push location-specific information to visitors — exhibit details, promotional offers, or contextual content — and drift into framing this as a navigation need. Pushing content to a known zone is a proximity marketing or information-delivery task, which has different technical requirements and different success metrics. Navigation specifically means helping someone move from where they are to where they want to go. Conflating the two leads to unclear requirements and disappointed stakeholders.
Assuming accuracy before measuring the environment
It is not possible to state what accuracy a system will achieve in a given building without measuring that building. Materials, ceiling height, rack shelving, temporary structures, and the number of people present all affect signal behaviour. Any assessment that assumes a specific accuracy figure — for example, claiming sub-metre positioning — without a site survey is unreliable. The correct approach is to treat accuracy as an unknown until a pilot or survey provides measured data.
Ignoring the ongoing operational burden
Indoor navigation is not an install-and-forget system. Beacons require battery monitoring and replacement. Maps must be updated when layouts change. If the system relies on a mobile application, that application requires maintenance, operating-system compatibility updates, and user support. An honest assessment includes an estimate of the annual operational effort required to keep the system functioning, not just the initial deployment cost.
Key checks before proceeding
- Quantify the problem. How many directional queries per day or week? What is the staff time cost? Are there measurable consequences like missed appointments or reduced dwell in key zones?
- Test the low-tech alternative first. Can improved signage, printed maps, or repositioned staff resolve the issue at a fraction of the cost?
- Clarify the user's device context. Will visitors use their own smartphones, or will the venue provide devices? If personal phones, what proportion of visitors can reasonably be expected to have Bluetooth enabled and a compatible operating system?
- Identify layout volatility. How often does the floor plan change? Frequent reconfiguration increases the mapping maintenance burden significantly.
- Establish a success threshold. Before any technology is selected, define what "working" looks like in concrete terms — for example, a reduction in directional queries of a specific proportion, or a measured increase in visitors reaching a particular zone.
- Review privacy obligations early. Even assessing whether navigation is needed may involve observing visitor behaviour. If the assessment moves toward collecting device signals or location data, UK privacy guidance on consent and data minimisation applies from that point.
If these checks confirm a genuine need that simpler methods cannot meet, the next step is to define the specific navigation requirements — accuracy, coverage areas, user interface constraints, and integration points — which is addressed in the following article in this guide.
