What should be considered during UAT to avoid issues post-launch?

The focus on performing User Acceptance Testing (UAT) with both peak load and average load simulation is crucial for ensuring that the system will operate effectively under various conditions after launch. By simulating peak loads, testers can identify potential bottlenecks and performance issues that may not be apparent under average usage scenarios. This proactive approach helps in understanding how the system's performance may be impacted when many users are accessing it simultaneously, thereby identifying and resolving issues before they affect end users.

Considering different load scenarios during UAT allows for a comprehensive evaluation of both the application’s performance and its ability to handle real-world user demands, leading to a smoother post-launch experience. In contrast, limiting testing to internal teams or focusing only on feature functionality does not provide a complete picture of how the system will perform under actual conditions. Additionally, overlooking user familiarity can lead to challenges in user acceptance and adoption post-launch, as users need to feel comfortable and competent using the new system.
