Personally, I like the way John describes the shift from managing "a web page" to managing "a conversation" as we see systems of engagement emerge in the enterprise… but…
While the balance of the slide is specific to Enterprise IT and the companies that define the era include traditional enterprise players like IBM, Digital and Microsoft, it isn't clear to me that Google and Facebook have had the same level of ENTERPRISE impact (yet?).
If you dig a little at this line of thinking, you clearly see that each era was/is defined by a number of different sources of value and competitive advantage.
With a hat-tip to insights gained from the work of Geoffrey Moore, Umair Haque, John Hagel, Valdis Krebs and others, I like to describe the transition we're seeing in the enterprise applications industry this way:
Combining the two models, we have a hint at the opportunity for enterprise application vendors moving forward. Helping users manage conversations, relationships and transactions with and across the enterprise is a significant source of new value and growth.
A couple of questions to consider as the enterprise application industry evolves to a "network of information nodes":
1. Will Google or Facebook be "the best known" enterprise vendor as outlined by John in the Social and Cloud era?
2. What comes after the Social and Cloud era?
