A guide to choosing telematics: key aspects and practical tips

Signing a contract with telematics service and fleet management system providers is a key moment in the work of every fleet manager. It is this decision that can determine whether daily duties will be streamlined or whether you will run into numerous difficulties for years to come. Which aspects are worth considering, and what thinking is essential when choosing the right solution?

Defining the company's hierarchy of needs as a starting point

Why start by defining your needs and weighting them? In an ideal world it would be easy to find a system that meets all our expectations. In reality, it is certain that there will be compromises. Decide what matters most in your view, taking into account the specifics of the industry you work in and the board's requirements for your work. Expectations and needs can differ widely. To highlight the importance of this point, below I illustrate an example hierarchy of needs for two different companies.

The hierarchy of needs of two different companies

It seems counter-intuitive, but not all companies put the quality of the GPS system first over additional features. What is more, some would even say that other, secondary features are more important. I will talk about them later on.

The test phase and collecting offers

Once your needs are defined, the search for providers and the test phase begin. At this stage it is worth creating a single comparison of all the systems tested, listing the features that correspond to your hierarchy of needs and the remaining additional options. The comparison should be built so that it brings the tested systems down to a common denominator as far as possible. The simplest way is to create a shared table, assigning a weight to each feature and scoring it. Weighted-average comparisons can always carry slight distortions due to poorly calibrated weights. I suggest using this kind of score as a reference point rather than the "final oracle" on which decision to make. When building such comparisons, take into account the different variants a given operator offers.

Save time, avoid chaos and gain full control over your vehicles

At this stage it is worth considering the following questions:

  • Are the features we originally deemed essential actually essential?
  • If you already have a system and are testing a new solution, it is a good idea to ask yourself: will the new provider broaden your fleet management capabilities while retaining the existing features you use with your current provider? If not, consider whether it will really be a change for the better.
  • Will the costs of the individual modules generate savings (both in time and in money)?
  • What does the cost structure for maintaining the system look like in relation to the planned budget? At this point you should also take into account the company's growth strategy and any changes to the fleet.
  • Will the provider ensure installation of the devices at every location you require?

Details worth paying attention to

CAN vs. OBD

As I mentioned at the outset, choosing a system will involve the art of compromise. This is exactly the decision you have to make when weighing up installing the tracker in the OBD port against a solution with the device wired directly into the CAN bus. Both systems have a range of advantages and disadvantages. Below is a table comparing the capabilities and risks of implementing each solution:

CAN OBD
Direct installation on the CAN bus gives far more data analysis options and, as a rule, greater accuracy. Unfortunately, question marks also appear. Currently most systems rely on a non-invasive connection to the CAN bus, but I recommend finding out to what extent the fitter interferes with the vehicle's electrical system, which may result in loss of the manufacturer's warranty and vehicle faults. Besides the manufacturer, it is also worth contacting the vehicle's owner in the case of leasing or long-term rental, and carefully checking the provisions of the individual contracts in this respect. Staying with installation, you need to consider the costs of a single installation and any transfers of devices between vehicles. On top of that there is the logistics of bringing the vehicle in for the service. Another downside of “hard-wired” installation is that in the event of hardware failure, the wait for a fitter means lost data and time, which could be avoided with trackers installed in the OBD port (you pull out the faulty module, assign the new IMEI number in the system, then plug in a device you can keep in stock. The whole thing takes 5 minutes. Easy installation also means easy removal by the vehicle user. Systems that serve vehicles this way should report that the device has been plugged in or unplugged, but from experience I know this does not always work correctly. It also often happens that the mechanical workshop that serviced the vehicle does not plug the tracker back in after running diagnostics, and the driver does not do so either (sometimes deliberately, but often quite unknowingly). Missing data caused by unplugging means no control, which leads to organisational mess and ambiguities that can no longer be cleared up. Suppose the device remained unplugged for 24 hours. During that time we cannot accurately verify how many km the driver drove privately, how many on business and how long they spent at a given customer. In this set-up it is also certain that such a tracker is easier to lose, which involves contractual penalties. The advantage here is the savings on installation costs, which do not exist, and the time saved on the installation itself.
The one-off installation costs mentioned earlier are incomparable with installing a GPS unit in the OBD port (there those costs simply do not exist). So the question arises: why consider this service at all? The answer, of course, is savings and the wealth of accurate data we can obtain. If an appropriate policy on the use of company vehicles is implemented and enforced, the company can save not only on fuel consumption (eco-driving policy) but also on a lower claims rate thanks to driving style analysis. With correctly implemented procedures and incentives, solutions of this type can pay for themselves, depending on the size and type of fleet in use, after a few, a dozen or sometimes only several dozen months. Be aware, however, that plans do not always work out. Access to vehicle data such as the odometer, fuel level etc. via OBD depends on the quality of the device but above all on the access granted by the manufacturer. As I mentioned earlier, with this type of device the quality and full reliability of the data often leaves much to be desired. Fuel analysis in terms of actual consumption, and verifying that refuelling matches the actual amounts on invoices, is usually out of the question. The same applies to analysing employees' eco-driving. In my experience, driving style data analysis made no sense. The systems picked up events that never happened, and fuel consumption analysis based on coefficients set manually by the provider showed that the vehicle was running on water or on jet fuel, burning 1,100 l/km.

‍Purchase vs. rental

Weighing up purchase against rental should not be as much of a puzzle as the question of installation method above. Everything rests primarily on your confidence in the quality of the hardware and software in use and on calculating whether and when such an investment could potentially pay off. Remember that if you decide to buy, you will still pay a subscription for access to the system and for the SIM cards in the tracker. Please also bear in mind that every device eventually breaks down, and the scope of the warranty in these cases is usually quite limited. When deciding to buy, we must be aware of possible unexpected costs of replacing devices during the year, which we do not face with rental (if the devices are not mechanically damaged, they are usually replaced without any problems). It is also obvious that before deciding to buy, rental seems the most sensible option for the first contract. The risk of buying devices straight after the test phase is being left with unsatisfactory hardware and software that you do not know what to do with.

Private/business journey identification and logging in to the vehicle

So far I have come across three solutions for logging in and identifying journeys. One is buttons in holes drilled into the vehicle's dashboard. When the button was pressed, the system identified the journey as private. Logging in was done by manually assigning the user to the vehicle in the system. This system caused a lot of problems, especially if users frequently swapped vehicles (it created a heavy workload for the employee operating the system). In addition, interference with the dashboard was received in various ways by new buyers when the vehicle was resold, not to mention situations where the vehicles were due to be returned to the leasing company. Below I propose two solutions that do not interfere with the vehicle and which I suggest considering during tests:

Solution Features and risks
User card / login tags Logging in is done by holding the card to a reader installed under or near the dashboard. Depending on the provider, the card serves only to identify the user, with driving modes switched in the app, or the card handles both (the user identifies a business journey with one card and a private one with another). An additional item we use is potentially an additional cost the user has to cover, and one more thing that can be lost or broken. With two cards per user, it is worth checking whether, after a journey, a correction can somehow be made if the wrong card was used for identification.
QR code Logging in is done by scanning a QR code, usually in the form of a sticker in the vehicle, with a phone using the app. The driving mode is changed via the app. I believe this login method is more convenient and potentially problem-free. The only obstacle may be a lack of internet on the phone, or technical problems with the app that prevent the journey from being identified.

Fleet management: supporting systems

More and more companies that deal only with vehicle positioning are expanding their services with supporting applications. With such solutions you do not have to look for external systems dedicated to fleet management and incur additional costs or, worse for the manager, run everything in spreadsheets. Systems of this type usually include tools such as:

  • Cost invoice import and cost centre management,
  • Applications for various types of requests from users,
  • Car sharing,
  • Scheduler,
  • Various registers: damage, tyres, certificates, contract parameters, etc.,
  • Vehicle handover reports,
  • Reports (environmental, statistical, automatic tax returns, VAT reports, etc.).

The solutions above significantly affect the quality and comfort of work of every specialist managing a vehicle fleet and are becoming an essential addition to the GPS services market. It is therefore worth taking into account the scope and costs of these services during testing.

SLA, the clause for hard times

An SLA (Service Level Agreement) is a clause in the main contract concerning the guaranteed level of service, which sets out standards and expectations regarding quality. Such clauses are appearing in contracts more and more often. Below are a few SLA provisions in the context of GPS services:

  • System availability: the provider guarantees system availability at a specified level (e.g. 98%). If availability falls below this level, the subscription fee for the month in question is reduced by a specified percentage.
  • Response time to a failure: in the event of a device failure, the provider is obliged to remedy the effects of the failure or take on the repair order within a specified time.
  • Guarantee of system development: when a company signs a contract for GPS services, it may happen that certain features are still under development but are promised to the tester soon. To protect the customer's interests, the contract may include a provision setting out detailed conditions and deadlines for implementing these features.
