For product of a certain size there are many people involved with research and feedback for each part/module of it. In addition, marketing and business people run their research as well.
Are there any best practices in documenting research and keeping research data that help balance the needs of each role and the user/customer?
Eg: Is the best practice to have one contact and notes space or separate lists that suit the need of each role? To keep notes? Or sum up, present, and trash notes.
Feel free to help me to make this question more specific - maybe it's too broad.
