Solving problems (vs. identifying them)
Often, we're hesitant to identify a problem out of fear we can't solve it. Knowing that we have to live with something that we're unable to alter gives us a good reason to avoid verbalizing it--highlighting it just makes it worse.
While this sort of denial might be okay for individuals (emphasis on might), it's a lousy approach for organizations of any size. That's because there are almost certainly resources available that can solve a problem if you decide it's truly worth solving.
Put yourself and your people on a path to finding problems without regard for whether or not they are capable of solving them. Queue them up, prioritize them and then go find the help your organization needs to solve them.
Just because you don't know what to do about it doesn't make it less of a problem.
