what are the three levels of disruption according to christensen's theory?
user
according to christensen's theory, there are three levels of disruption. 

the first level of disruption is low-end disruption, where a firm enters the market serving the needs of customers whose needs are not being met by existing technology. 

the second level of disruption is new-market disruption, where a firm offers a product that consumes a new market that was previously nonexistent. 

the third level of disruption is called sustained disruption, which is when an established firm successfully disrupts itself by maintaining the same set of users while introducing the latest technologies.
