Complacency

 When you are doing badly, you know you have to do better. So you work towards it. 

When you are doing reasonably well, it's tougher to be motivated. You might think, 

"I'm doing well. Why work harder?" 

And that's true of organisations as well. If you don't have obvious shortcomings, it's easy to fall into the complacency trap. And stop trying to be better. 

An example- IIMs think they are getting the best students. They could be, but even a low-ranked American university has more diversity in their student body. International diversity. I know, because i worked in one. Faculty diversity too. 

Just so you don't get complacent as an organisation, I suggest you revise goals every three years or so. And this applies to educational institutes as well as corporates. And see what happens.
