Which of the following describes post-launch research?

Post-launch research is essential for evaluating how well a product performs in real-world settings once it has been launched. It focuses on gathering feedback from actual users to understand their experiences and any usability issues they may encounter. This type of research helps designers and product teams gather insights on user interaction, identify any obstacles users face, and assess whether the product meets its intended goals. By analyzing this feedback, teams can make informed decisions about potential improvements or features for future updates, enhancing overall user satisfaction and the product's effectiveness.

The other options refer to different stages of research: the first option relates to market research before a product hits the market, the third option focuses on gathering initial user desires during the development phase, and the fourth is about evaluating design processes rather than user experience after a product's release. These contexts do not align with the primary goal of post-launch research, which is centered on assessing usability after the product has already been made available to users.
