Great rant but hardly the reality
Johann Hari's diatribe against the whole profession of management consultants was a great rant but doesn't represent the reality.
I'm sure there are good and bad consultants, but in 15 years in the profession I have never done a project that fits his "cut 30 per cent of the workforce" formula.
I have helped small technology start-ups to grow and expand; I have helped big firms to manage their R&D more effectively (often by doing more); and I have helped the NHS make sure that patients with major trauma are treated by doctors with enough experience to improve their chances of survival.
