Comparison Disruptive Innovation versus Blue Ocean Strategy
Jorge Possollo, Member
Disruptive Innovation (DI) can also be completely new, if you have a new market disruption as you can read in Christensen's work.
In practical applications, I believe they are quite similar, DI theory being more academic and BOS being more practical, they can be applied in a variety of scenarios but I have found DI works at its best in company start-ups, whilst BOS is slightly more effective analysing existing businesses, but you can really get a kick out of combining the 2.
Basically 2 very effective differentiation / strategic positioning tools that can really be effective.
