There is one principle of organization that every human should adhere to, particularly people who design products. Day after day, I see companies break this rule, and it is 100% of the time to their detriment. In this article I will explain what that rule is, and what it means to product and service design. I’ll also raise the possible implications of this phenomenon on organizational management, collaboration, and general performance. The psychological phenomenon I will be discussing in this article is known as Miller’s Law. Rather than just tell you what Miller’s Law is, I ask you to take part in this exercise for a more immersive learning lesson.
