Which guiding principle encourages improvement based on user feedback?

The guiding principle that encourages improvement based on user feedback is "Progress iteratively with feedback." This principle emphasizes the importance of continuously seeking and incorporating feedback from users throughout the development and delivery process. By engaging with users and understanding their experiences, organizations can make informed decisions and adjustments that enhance the value of their services.

This iterative approach allows teams to refine their offerings incrementally, rather than attempting to deliver a perfect solution all at once. It also fosters a culture of collaboration, as teams are encouraged to actively solicit input and react to user needs. This not only leads to better alignment with expectations but also enhances user satisfaction and engagement.

In contrast, the other principles, while valuable in their own right, do not focus specifically on the aspect of feedback. "Keep it simple and practical" promotes minimizing complexity, "Focus on value" centers on delivering what matters to stakeholders, and "Optimize and automate" entails improving efficiency. Though these principles contribute to overall service delivery and improvement, they do not directly highlight the importance of iterative progress driven by user feedback.
