Planning for Different Perspectives in Developing Validity and Efficacy Arguments

No field or profession can prescribe what is or isn’t validity or efficacy evidence. Different fields have distinctive ways of asking questions, addressing a literature, criticizing ideas, and presenting arguments. The differences make sense from a socio-cultural perspective as each of these stakeholders—you might call them customers if you are in marketing or users if you are in product development—is coming from a different culture of evidence and set of life experiences. But this seems chaotic if you are trying to collect validity or efficacy evidence and construct an argument with it.
