Well there is a saying ; a system is good as it operator . so investment in people is a must . Lots of companies spend millions on systems but they are not willing to spend maybe thousand on staff . I mean by staff qualified and the one who works smart and hard .
Want to be the best , compute , make profit and save cost then invest in people not in systems .
Good example telecom companies . They are selling same technology with maybe using same vendors . But what makes company better than other ?!
Simply people !
