"Compare notes" means to exchange information and observations with others to gain a better understanding of a particular situation. However, there are several other phrases that can be used to convey the same meaning. For example, "compare experiences", "collaborate insights", "share viewpoints", "exchange thoughts", "discuss findings", "pool observations", "review data", "combine knowledge", "compare analyses", "assess feedback". Each of these alternatives has its own nuance and emphasis, but they all imply a willingness to work together and learn from others to achieve a common goal or improve performance. Whatever phrase you choose, the key is to be open and receptive to the perspectives of others and use that information to make informed decisions.
