One of the most dangerous combinations is not knowing the situation as a whole and having complete self-confidence. In the business world, it's more than typical. Because who knows everything?

The answer is good enough. Good enough is a tricky expression - similar to fair enough. What is good and what is enough?

Good is easy to describe - what is good for the firm's client. Enough is the key. Because enough is unfortunately the whole knowledge. So good enough mean the subset elements of the whole knowledge. What is relevant in the company's market. Industry knowledge can not be overcome, there is no panacea.
