Expert as a service

Expert-as-a-Service (ExaaS) is an online delivery model of human consulting and/or automated knowledge transfer. Similarly to SaaS (Software as a service) the concept of ExaaS comes from the remote nature of processing data and/or providing service. The user of ExaaS accesses the service through a webpage, VoiP, IM, etc. or any related mobile app. Typical ExaaS providers are consultants, lawyers, physicians, teachers etc. 
Biztech Magazine claims that "...Everything as a service...Clouding Will Disrupt the World..." and according to Business2Customers magazine there are "...3 Reasons Why Experts-as-a-Service is the Future of Consulting..."
ExaaS is the general term for newer consulting or expertise based online services like CaaS (Consulting-as-a-Service) or JaaS (Justice-as-a-Service) 
CaaS companies or individuals deliver online consulting services (The Consulting-as-a-Service model (CONaaS) by Luke Marson, sales diagnostics by Miklos Kadar,
