Putting a finger in the wind is to reach a corporate twaddle decision arbitrarily, with no clear rationale. This is often how business is done, based on a hunch or sometimes just the need to be 'doing something or looking busy'. Weather boffs and sailing types like to know which way the wind is blowing; of course it may not be (see above picture where there is a flat calm). So here the finger raising would be energy wasted and more useful things can be done with the no-longer-raised digit. Bonus tip: Try not to mix your office-speak expressions unless you are an advanced practitioner, e.g. "Don't put your finger in the wind and call it due diligence"!
