> One of our product managers is a grandmother > However, she has frequently had insights and observations that none of us would have come up with > So yes, absolutely, unless your company wants to be in a very specific niche, the lack of true diversity in your company is a drag on your success. The conclusion you are drawing here, does not follow from your two observations above. The fact that your product manager has had insights, that nobody else had in team, does not mean a "lack of true diversity in your company is a drag on your success." Some diversity may help in certain situations and in others not. The above mentioned insights and observations might just be the result of competence and more experience of the product manager or incompetence of the rest of the team. There may be many other reasons. We don't know. We have one observation and should refrain from generalizing. That this is because of more diversity is just a speculation. A speculation that fits an often repeated narrative, but that doesn't make it a logical conclusion.
