You only need qualifications if they are a prerequisite for running your
business, for example, if you’re setting up as a dentist or consulting engineer. Otherwise,
they’re not essential, although they may give you credibility.
The business world and academia require a different or complementary skillset for
success. Strategic thinking and a broad range of skills are what counts. Research might
only be carried out on a 'need to know' basis because the key factor is to get things done.
