Quality assurance is critical in software development. Without it, software development is like a house with poor walls – it can stay together but it probably won’t (and you’ll be stressed all the time).
Gem Develops commercial software is not going to be successful if there are faults in the usability. These can be anything from the usability of the UI to speed and safety of the software. There are many parts in software testing and all of them have to be taken care of so that the software can work the way it is supposed to.
