2. The question you are trying to answer should be understandable so people know exactly what it is you are trying to answer.
3. It has a process and the steps are easy to follow so it can be replicated accurately for the purpose of further research.
4. It is done in a way that makes sure no unexpected things cause change to the outcome. It's like when you're trying to find what you're allergic. You don't eat a bunch of foods and wait for a reaction, you eat one thing at a time so that way you're not missing any factors.
Does that make sense?

The systematic naming of chemicals is the IUPAC name (International Union of Pure and Applied Chemistry).
Here are the purposes to use it:
1/ It identifies exactly one chemical.
2/ All people over the world can understand it, wherever they are, whoever they are.
It looks like how we recognise the number 1 - 2 - 3: the Americans call them One Two Three, but the Russian call them Odin Dva Tri, etc
Hope this answer can help you!
