- How can user perceived reliability be improved?
-

-
Lack of technical errors,
-
No installation problems.
Yes. If the user is unable to operate a service, it may be perceived as poor reliability though in the sense of technical reliability will probably not.
It is important -- or very important. If the users cannot operate a system, they will not use it. For Real-time systems with person-to-person communication, several results show it is essential.
It is here suggested 3 ways:
- Enhance user interface so it is easy to understand and operate – choose a system that can be operated by an end-user, not only demonstrated. The user need to be able to use the service anytime, and that is when the service is needed.
- Enhance technical reliability – this is mainly the service provider’s responsibility and can be revealed by talking to other users. If their attitude to technical errors is not acceptable, do something with it. The experience is that this will not solve by passive waiting.
- Be careful with installations – this is about installing, upgrading and remaining the installation. To install for first time may result in new demands: Am I able of getting a public, fixed IP- address with my subscription and am I able to traverse through the firewall? Upgrading the installation: This can lead to be asked question the installer does not know answer to (opening certain Ports, identify microphone driver or license key received some time earlier. Remaining the installation: This means that equipment used for the communication service (e. g. microphone, camera) has been borrowed for other purposes and need to be found and reinstalled.
