In one of my previous articles I wrote about ways to design for human attention. Attention is closely linked with working and short-term memory. However, this article is going to be focused on the entire human memory system. We have two main types of memory: short-term memory (STM) and long-term memory (LTM). In computer science terms, you might imagine short-term memory as RAM and long-term as the HDD. I will try to describe how they work, how we can design interfaces that eliminate confusion and how to lower the cognitive effort users need to make. All of this should result in a more human-centered user experience.
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.
