What Should You Include in a Tour Guide System Tender or Procurement Specification

A workable tour guide system procurement specification needs to say six things clearly: where and how the system will be used, what it must do, how performance will be verified, how delivery and acceptance will work, what support follows the sale, and how the fleet can grow. Everything else in the document is detail around those six.

Museums, heritage authorities, exhibition operators and public bodies often have to write a tender for an audio guide system without having bought one before. The usual result is a document that is either too vague, in which case every supplier quotes something different and nothing can be compared, or too specific, in which case it describes one product and quietly excludes the rest. A good specification sits between the two: it states the outcome you need and the evidence you will accept, and leaves the supplier room to propose the equipment. This article walks through what to write under each of the six headings and why.

Describe the Use Before the Equipment

Start with the place and the visitors, not with the product. Say what kind of site it is, how long the route is, how many people the system must serve at the same time at your busiest moment, how many languages are needed, and whether tours are led by guides, taken alone, or both. Add the physical conditions that affect radio signal and handling: thick walls, outdoor sections, noisy production areas, narrow spaces where cables cannot be run. A supplier who reads this can propose a fitting system. A supplier who reads only "supply 200 audio guide units" can only propose a number.

Write Functions as Requirements, Not Features

State what the system must let people do. For example, that a visitor can hear the correct explanation at each stop without pressing a button, that a guide can address several groups on separate channels at once, or that a listener can speak back to the guide. Avoid listing features by brand name or by a single supplier's term. If you need automatic playback at each stop, say that, and specify how many audio segments and languages you need to store. If you need both guided and self-guided use, ask for a system that supports both, so you do not end up buying two fleets.

Say How Performance Will Be Checked

This is the clause most often missing, and the one that matters most. Quoted figures for range, battery life and sound quality are measured in ideal conditions. Write into the document that shortlisted suppliers will provide sample units, that the samples will be tested on your own route, and what counts as a pass. A reasonable test covers the longest path you run, the thickest walls, a full set of units switched on together, the noisiest area, and a full day of battery use. Setting these out in advance protects both sides, because everyone knows what will be measured.

Delivery and Acceptance

Specify the delivery date or schedule, whether the order can be delivered in stages, and how you will accept the goods. Define how many units you will inspect on arrival, the period in which you can report faults, and what the supplier does about units that fail on arrival. If the system needs content recorded and loaded, say who produces it and when, and make delivery of the content part of acceptance. A tender that treats equipment and content as separate things often ends up with working receivers and nothing to play on them.

What the Supplier Owes You After the Sale

Support terms are a part of the price, and a tender should ask for them in the same way it asks for equipment. Ask for the warranty period and what it covers, how a fault is reported and diagnosed, how repairs or replacements are handled, how long spare parts will remain available and whether software updates are included. It helps to know what a clear answer looks like. In the YingMi M7C documentation, for example, main units carry a 2-year warranty, a fault is first diagnosed from a short video or description, a unit that has to come back is supported with return instructions and customs paperwork, and critical faults confirmed by the supplier are eligible for replacement within the warranty period. Spare parts are described as available long term and firmware updates as free. A tender that asks each bidder to state terms at this level of detail makes proposals easy to compare.

Leave Room for the Fleet to Grow

Venues expand, add languages and add routes. Ask whether units bought later will work with units bought now, how long the supplier expects to keep the model in supply, and whether the system can be customized if your needs change. Some suppliers offer OEM and ODM services for this. The M7C documentation describes a process that starts with confirming requirements for software and hardware, moves to sample creation with appearance, circuit board and software prototypes, and ends with testing and compliance before mass production. If customization matters to you, ask each bidder to describe their process in the same way.

A Starting Point You Can Adapt

Comparing the Bids You Receive

When the proposals arrive, resist ranking them by total price alone. Ask for an itemized quote that separates equipment, accessories, content and support, and put the support terms next to the price. A lower total that leaves out charging cases, content or repair coverage is rarely lower for long. Score the test results from the sample trial as heavily as the price, because they are the only part of the bid you have seen with your own eyes.
