Good arguments against low-end discruption.
From my experience in the industry, the model that Roose describes for banking very much applies for top management consulting as well.
What I'm seeing now is that Silicon Valley and Generation Y are breaking it – not to the degree that it doesn't work anymore at all, but diminishing the model's success of providing a massive competitive edge. In earlier days, the smartest, most ambitious people went into academia and public service. Later, they went into the financial services and management consulting. Now they're heading to tech companies, or (gasp) become entrepreneurs or freelancers.
With my work experience spanning one extreme mentioned in the article, Accenture, and the other one, IDEO, I can assure you that strong, tight, friendly cultures work way better at least in consulting.
Jugaad is a Hindi word meaning “the gutsy art of overcoming harsh constraints by improvising an effective solution using limited resources”; sometimes by bending the rules.
