Definition - What does Seamless Integration mean?
Seamless integration is the process where a new module or feature of an application or hardware is added or integrated without resulting in any discernable errors or complications.
It simply means that whatever change is being applied to a system, it happens without any negative impact resulting from the integration. It is often used in the context of software and systems development, as well as for computer hardware.
Techopedia explains Seamless Integration
The term seamless integration is used in the event that a new application, module or device is added and works smoothly with the existing system. It is also used to describe a future upgrade to an existing system, to assure stakeholders that there will be no problems resulting from the integration. A common example of this, or at least the lack of it, can be seen with many mobile applications where a feature update often results in multiple bugs and may even result in the application not working at all for some hardware configurations.
Seamless integration is the result of careful planning which may even have started during the design phase of the system or application. Serious integration testing is also conducted on a dummy or backup system before the integration is applied to the actual system, just to make sure that all the bugs and possible complications are removed.
