Good design is a lot harder to notice than poor design. - Don Norman, The Design of Everyday Things.
Those who have read the book must have read this statement. Well if you see it’s kind of true. Design that is good fits the needs of the user making the design invisible whereas designs that are bad somehow draw attention and one can actually notice the inadequacies. Good design acts as a mirror that actually shows you what they are while bad design quite does the opposite.
In today's world, designing a product while building a brand is as important as the product itself in order to garner the desired emotion/feeling of the user. For this to be successful, the real problem needs to be figured out and what and how this product is going to solve this. It should be designed in such a manner that a user doesn't have to spend more time figuring out how to use it, etc. This will ensure the user to use the product more and give them a good experience. It will give them clarity about the product, its features and help them achieve the desired objective they have in mind.
Bad design on the other hand will confuse the users making them leave the product. Products having bad design will impact the user experience negatively.
Good designs are simple yet aesthetic. Good design will fit perfectly in the users' needs making the whole experience seamless. Good designs are easy to understand, fulfill the user’s needs, and are problem solver.
Bad designs are generally confusing, have a bad layout. They have irrelevant content.
We still come across products which have bad design. So in order to ensure a seamless experience and get the users hooked to your product, it is necessary that it not only fulfill their needs but also do it delightfully. What they want to do but at the same time remove the pain points by not compromising with the look and feel of it.
