The professionals at Aleph Infotinuum Services contend that there is one mistake which is even bigger: pretending that the bureaucratic programming one received from one’s childhood schoolmasters can pass as surefire instructions for qualified business management.
Businesses don’t exist to provide jobs or to satisfy owners (e.g. shareholders). Businesses exist to serve consumers — and the extent to which the employees & contractors working for a particular business are successful at serving consumers determines shareholder dividend as well as the quantity of available jobs.
Despite what your associates fresh out of MBB (Master of Business Bureaucracy) school might think they’ve learned, business managers don’t exist to grow their employer’s business. Business managers exist to serve consumers — and the attitude they bring to such consumers-come-first duties determines their professional legitimacy (if not their material compensation amid an economic climate of too many MBBs confusing guild credentials with actual qualifications) as well as the long-term growth of their employer (as opposed to MBBs focused on short-term quarterly reports delivered to the bureaucrats pretending in turn to be their managers).
That’s not to say that it’s only ever a one-way street. Consumers who nickel & dime their various vendors sometimes find themselves shut out of future opportunities for meaningful association. Supervisors who nickel & dime the coworkers whom they pretend are beneath them sometimes find themselves without anyone willing to work either hard or smart — and if they insist that pleasing them is the only means toward pleasing the employer’s customers or clients, they are unqualified to call themselves business managers.
There is good news: after you come to terms with the big picture business management stuff, day-to-day pitfalls such as the ones outlined within the article linked below start to seem more like temporary annoyances than chronic pain points.
