Even the most experienced designers with years of expertise can never be completely confident that they know exactly what users need, think, or how they behave. Usability testing plays a crucial role in addressing this uncertainty.

In addition to this, usability testing is conducted for several reasons:

• To identify usability issues. Usability testing helps identify any problems or challenges that users may face when using a product, such as confusing navigation or hard-to-read text.
• To ensure user satisfaction. By testing a product with real users, the product team can ensure that it meets the needs and expectations of the target audience. This can lead to increased user satisfaction and loyalty.
• To increase adoption and revenue. A user-friendly product is more likely to be adopted by users, which can lead to increased revenue and success for the product.
• To inform design decisions. The feedback and insights gained from usability testing can inform design decisions and help ensure the product is designed with users in mind.

While usability testing has many benefits, it is important to consider whether it is necessary and appropriate for the specific product and stage of development. Usability testing should not be conducted solely to validate preconceived ideas or assumptions.
