Final answer:
Synchronous is NOT one of the four S's in deploying a successful ESN.
Step-by-step explanation:
The answer to the question is c) Synchronous.
In the context of deploying a successful ESN (Enterprise Social Network), the four S's refer to Support, Strategy, Sponsorship, and Synchronization. Synchronization is not one of the key pillars in the deployment process, and it refers to the coordination and alignment of activities within an organization. While it is important to have support, a well-defined strategy, and sponsorship from stakeholders, synchronous activities are not directly related to the successful deployment of an ESN.
