Reasons to test your prototypes and features:
User testing helps you save time and money:
By detecting mistakes and usability concerns early on, you can ensure that the product you finally release is as bug-free and user-friendly as possible.
What happens if the testing step is skipped in order to have the product built as quickly as possible? You will spend a significant amount of time and money fixing the product after it has been released. This is not only infuriating, but it is also detrimental to the bottom line.
User testing yields surprising results: No matter how comprehensive your original user research was, or how certain you are that you have developed the best answer to your user's problem, fresh insights are always available.
Observing real consumers engage with an early version of your product will reveal flaws that you would not have discovered otherwise.
User testing increases user satisfaction: It is all about putting the user first in Design Thinking. By obtaining first-hand customer input, you may make more informed design decisions, thus boosting user happiness.
Prototyping and testing will keep you focused on the user at all times as a designer. Of course, happy consumers are excellent for business!
