One way in which technology is adopted is when an existing process is automated and made more efficient, cheaper, or reliable. Another is when a technique or innovation is applied to an existing process to drastically alter the way it occurs. The disadvantage of the latter is that it requires the idea being sold to someone who has to change to adopt it, and thereby carries a risk of failure. Applying a technology to merely streamline an existing process is a simpler to adopt as the implementation merely involves oiling an existing solution.
