Kasutuslihtsusnõuded

Kasutuslihtsusnõuded, commonly translated as usability requirements, are a set of criteria that define how easily and effectively a user can interact with a system, product, or service to achieve their goals. These requirements focus on the user experience, ensuring that the interface is intuitive, efficient, and satisfying to use.

Key aspects of usability requirements often include learnability, efficiency, memorability, error prevention and recovery, and satisfaction. Learnability refers to how easily new users can perform basic tasks. Efficiency measures how quickly experienced users can perform tasks. Memorability addresses how well infrequent users can re-establish proficiency after a period of not using the system. Error prevention and recovery concern how the system helps users avoid errors and recover from them when they occur. Satisfaction relates to how pleasant the system is to use.

Establishing clear usability requirements is crucial during the design and development phases of any project. They guide designers and developers in creating user-centered solutions and provide a benchmark against which the final product's usability can be evaluated. These requirements are typically derived from user research, competitor analysis, and an understanding of the target audience's needs and capabilities.

Meeting usability requirements leads to increased user adoption, reduced training costs, fewer support calls, and ultimately, greater user satisfaction and loyalty. They are an integral part of ensuring that technology serves its intended users effectively and without unnecessary frustration.
