As a leader, your people will likely come and tell you they have solved a problem that has been plaguing your business. What they may mean, however, is that they have fixed it. Just because a problem goes away or is not occurring anymore does not mean that it has been solved.
When organizations run into problems they don’t know how to solve - really tough problems - the first step is often to call in a subject matter expert. Subject matter experts, be it the OEM (Original Equipment Manufacturer) or a local resource, will lean on their experience to try and draw out a solution. If the problem falls outside of their abilities, they’ll often proclaim the problem impossible.
