Especially if it's from the board or your advisors. It's not only politically astute and helpful to "take the help" when it's offered, it actually can make your life easier. Often times the board has access to models, consultants, interns, and insights that you could only dream of.
It's not wrong to make them work and use their network to help uplevel your metrics, dashboards, or best practices. After all, if you're truly all in this together then they should want to help you achieve the best result possible.
So don't take offense or act like you know better than them and you don't need their help. True, you might know more, and you really might NOT need the help.
But do yourself and your team a favor and take it and see where it leads and what you learn.
