"There are two ways that big advances happen in business IT. One way is
top down: the powers that be - IT departments and corporate executives
- make a decision to bring a new system into a company, and employees
are required, either happily or unhappily, to use the system. (...) The other way is bottom up: individual employees or business
units begin using a new technology, without any formal imprimatur from
higher-ups, and it proves so valuable that IT departments and corporate
execs have no choice but to embrace it."
