Some of the best restaurants in the world have open kitchens. Patrons can walk into the kitchen and see how their food is cooked and be part of the experience. The same applies to product conversations as well. You should let your customers peek into how you think as a team to design products, how your work together, how you turn concepts into ideas and how you take decisions.
While sharing and discussing product concepts, you will fail to capture ideas, misinterpret customer comments, and make mistakes. By keeping your work open within a trusted group of colleagues and customers, you have the opportunity to receive feedback from them and take corrective action.
Openness is one of the best ways to engage customers in your product conversation. It is important to notice that customers may not agree with everything you do. But at least they will know what you are doing and will appreciate the honesty.
