I've read How can I ask for candid feedback from my manager? and How politely decline positive feedback? and concluded that these answers were primarily for the individual, i.e. feedback to the performance of the individual.
My question pertains to the subject of a tool, dashboard, widget, script that I am demonstrating.
Ultimately, when I demonstrate a new dashboard to stakeholders, I answer questions that they have the moment of, i.e. when I am demoing dashboard 1, and a person has a question, I answer it right away or if I had thought of the problem, I've created slides/sections later to address it.
If the question was something I did not think of, I write it down for further investigation and get back to the question asker at a later time.
At the end of the demonstration, I always ask "ok, that about wraps it up, are there are questions or comments?" The responses I receive are generally along the lines of praise, i.e. "good work, I love !" instead of further feedback and features that I need to implement or problems to be addressed.
My question is how can I frame the conclusion of a presentation to solicit further issues with the product/deliverable/dashboard I am presenting instead of praise?
(Note, I am not admonishing praise, but rather I want to focus the Q&A on things I need to work on next)
