As discussed earlier as well, the product owner is the face of the customer, hence, it is really important for the product owner to stay in constant contact to understand the vision better and take updates on the product. The frequent interactions allow the product owner to stay up-to-date with feedback, MARKET situations or any change in the requirement. This not only helps the product owner but it also builds a level of trust and confidence among the customers. In a few of the organizations, this INTERACTION is being handled by the product managers, thus, these two roles can fill in the gap wherever required. 

The regular interactions also help in aligning the expectations from the customers, the product owner can, from time to time, showcase the developed product and ask for the feedback. In this manner, if something was missed out in the INITIAL discovery phase that can be catered now. If we talk about SCRUM, there are no product managers, but in agile, we have product managers sitting above the product owners and looking at the product at a higher level. The product managers are more into the market side whereas the product owner’s involvement is more with the development team.
