Ever lost your glasses only to be told they are someplace on your body obscured from your view?
(Like on top of your head?)
It happens.  People see things that are right up in their face.  And that's about it.  So, to make it easier to catch people's eye, we put books there, project slides there, and wave funny flags there.  Personal perspective, bias, and expectations make some things invisible to the active viewer and that's what is mean by "blind spots."
The worst part about blind spots is that we all have them.  Building trust in an organization is important because when it's coming from someone we know we can trust, instead of brushing away well-intentioned feedback, sometimes we can just look: the paper stuck to the heel of your shoe.  You know that don't want it there, but only when you're aware of it.  A friend who notices something because they're seeing you from a different perspective than you, can tell you about it.
"Thanks friend!  -You've got my back."
"And I've got yours.  -A friend in need..."
So, working together we can more quickly find errors, oversights, and omissions.  We fill in the gaps we missed, and none of us makes a fuss or keeps score all the time.  Trusting each other to tell when it really counts makes all the difference in both work effectiveness and efficiency.

Ever notice with the passage of time that great technological advances keep happening at an ever increasing pace?  Yet, people seem less and less satisfied with the quality of life they experience pervasively?  Subjectivity certainly enters the picture, yes.  But, what's going to make the difference for your customers, employees, strategic partners, and the organization as a whole?  All said, what supports the whole ecosystem of work in your world?
Is the question even answerable? - Not for most people. 
​However, I see an opportunity here.  I'm talking about something bigger than just turning a buck, or passing the buck.  We live in an age where anyone can invent entirely new paradigms for living, interacting, and interpreting what's happening all around us.  Focusing on what people outside the organization, such as customers want, makes all the difference in what we notice.  -What's missing.   What's working, and who cares?
Being attuned to what our social environment is pulling for has things jump out for us, which we never noticed before, and Real Options unfold for us to jump into action that never existed in our perception.
What can you do on a daily basis to attune to customer wants and needs?
