Description: The ‘scenario’ refers to a narrative description of a specific situation in which a user interacts with a system. This concept is fundamental in software development and user experience design, as it allows designers and developers to better understand user needs and behaviors in concrete contexts. A scenario may include details about the environment, user actions, system responses, and expected outcomes. By creating scenarios, potential issues can be identified, usability can be improved, and it can be ensured that the system meets user requirements. Additionally, scenarios are valuable tools in various development methodologies, including agile and waterfall approaches, where they are used to define tests and validate functionalities from the user’s perspective.
