I bet you didn’t know this about simplicity in UX.

Go walk into a restaurant, sit down, and glance at the menu. The options are clear, neatly categorized, and easy to scan. You place your order, and within minutes, your food arrives.

You feel good as everything was effortless, right? But behind that effortless experience is a carefully designed system absorbing the complexity so that you don’t have to deal with it.

The best businesses operate this way. They don’t eliminate complexity; they hide it from you. For instance, take these giants as examples;

• Google instantly sifts through billions of pages, and filters out the noise, to provide you relevant answer in mseconds.

• Flipkart stores your details and optimizes logistics to ship so you only have to tap 'Buy Now,' and your order is placed.

• Zomato coordinates with the restaurant, delivery partner, optimizes the route, and updates ETAs, all seamlessly to simply show you “Your order is being prepared."

This is Tesler’s Law, or the Law of Conservation of Complexity, in action. It states that complexity in a system can’t be removed, only shifted.

And, almost every other process has an unavoidable level of complexity. The key is to decide who has to deal with it, the business or you as a user.

So, the companies design systems where all the hard work happens behind the scenes, such that the experience for customers feels obvious, natural, effortless, and seamless.
