I loved the clear examples of goals vs. objectives vs. activities. It’s important to make sure as Cathy said that the activities being conducted are really in service of the overall goal or objective. And conversely, to identify activities that will help you meet the goals and objectives that you’ve identified as important.
I think each part of the research process has unique circumstances that can benefit from stakeholder input. For example, during formative research activities, working with stakeholders is critical in learning about the community and how it operates. Without this understanding, researchers could jeopardize their ability to work in a given region in an effective and respectful manner. The trials might not be acceptable or may not be designed in a way that is feasible to conduct. A study could be thwarted before it begins or recruitment may be slow because of a lack of stakeholder trust and support, or because it lack what is realistic for participants.
