What question should you ask to get feedback on whether the software met customer expectations?

The question regarding how the software has worked for what the customer was using it for is the most effective way to gauge whether it met their expectations. This question directly addresses the customer's specific needs and experiences, allowing them to articulate whether the software fulfilled its intended purpose and if it aligned with their expectations. By focusing on their actual usage and outcomes, you gain insight into the software’s performance and relevance to their tasks.

In contrast, asking about delivery timelines, installation problems, or new features does not directly assess the software's effectiveness in meeting customer needs. While these aspects may provide useful information, they do not capture the overall satisfaction with the software's functionality and usability in relation to the customer's specific goals. Thus, understanding the direct impact on the customer’s work is crucial for evaluating success and areas for improvement.
