Okay kiddo, so you know when you play with your toys, you want them to work well and be fun to play with, right? Well, when grown-ups make computer programs or apps, they want them to work well and be useful to people. That's where ISO/IEC 25010 comes in.
ISO/IEC 25010 is like a group of rules grown-ups use to make sure their computer programs are good. It tells them what things they need to do to make sure their program is easy to use and doesn't have any problems.
For example, one of the rules is about how reliable the program is. That means that the program shouldn't break or stop working suddenly while you're using it. Another rule is about how easy it is to learn and use the program, so that people can understand how to use it without getting confused.
Overall, ISO/IEC 25010 helps grown-ups make sure that computer programs are helpful, easy to use, and don't have any problems. And just like how you like your toys to work well, grown-ups want their computer programs to work well too!
