The institute of management services offers courses for those who are already mid-career and qualified through work experience, and who wish to apply this kind of management technique to their own sort of work. It also offers certificates for new entrants into commerce, industry or public services with a couple of years' experience who will practise under supervision. It's perfectly possible. You would usually be taken on and put in a company's graduate management training programme. Typically, a combination of part-time study and work under supervision.
Employers usually expect trainees to become members of the institute of management services.
Thanks for the chat. We'll see about that . . .
