Grouping or chunking
Have you ever wondered why every book is divided into chapters and then into sections and paragraphs
We humans can’t consume or handle large amount of information but we love bite sized chunks of information
Examples
If I show you a washing machine and it has 100 buttons to do different functions and another one which has like 10 buttons which one will you prefer to buy.
SOLUTION: Group relevant controls together so they make sense to user
