Although failed designs are sure fun to look at and try to fathom how they happened, they also affect our lives in smaller or bigger ways. After the funny part fades away, then follows confusion, then frustration and annoyance. Some design fails can even be hurtful, unintentionally racist or sexist, and in some cases, a bad design can lead to physical harm, such as when a poorly designed machine or tool causes an injury.

This is a great example of how important it is to do a test before reaching a final result. Just imagine how many of these examples could have been avoided, if not all of them. So why do people miss such a crucial step? Well, one of the main reasons is resources. To do a test drive, in some cases, can be time-consuming and expensive, especially for small businesses or individuals who are making, for example, cake for their child's birthday.

However, keep in mind that the cost of not testing can be even higher. A bad design can waste resources, cost money, and harm a company's reputation. It may even result in legal liability in some cases if the design causes harm to users.

Overconfidence is another reason why people may avoid testing. They may believe that they have created a design that is error-free and does not need to be tested. This way of thinking can be dangerous because it can lead to the design missing potential flaws and weaknesses.

Luckily, most of the design fails here are rather harmless and will be more of a funny memory than a lifelong injury. It only depends on how you will look at it and whether you will try your best and learn from the failure or keep failing in the future until you do.
