What is Usability?
Usability refers to how easily and efficiently users can learn to use a product and achieve their goals. It’s a critical aspect of user experience, focusing on making designs intuitive, accessible, and satisfying to use.
Key Factors in Usability:
- Learnability: How quickly new users can understand and start using the product.
- Efficiency: How quickly users can perform tasks once they know how to use the product.
- Memorability: How easily users can remember how to use the product after a period of not using it.
- Error Management: How well the product helps users avoid errors and recover from them when they occur.
Example: A well-designed e-commerce website with intuitive navigation, clear instructions, and a streamlined checkout process is more likely to provide a positive user experience, leading to higher customer satisfaction and retention.
