Is e-commerce the same as e-business?

While some use e-commerce and e-business interchangeably, they are distinct concepts.
In e-commerce, information and communications technology (ICT) is used in
inter-business or inter-organizational transactions (transactions between and among
firms/organizations) and in business-to-consumer transactions (transactions between
firms/organizations and individuals).
In e-business, on the other hand, ICT is used to enhance one’s business. It includes
any process that a business organization (either a for-profit, governmental
or non-profit entity) conducts over a computer-mediated network. A more comprehensive
definition of e-business is: “The transformation of an organization’s processes to
deliver additional customer value through the application of technologies, philosophies
and computing paradigm of the new economy.”
Three primary processes are enhanced in e-business:5
1. Production processes, which include procurement, ordering and replenishment
of stocks; processing of payments; electronic links with suppliers; and
production control processes, among others;
2. Customer-focused processes, which include promotional and marketing efforts,
selling over the Internet, processing of customers’ purchase orders and
payments, and customer support, among others; and
3. Internal management processes, which include employee services, training,
internal information-sharing, video-conferencing, and recruiting. Electronic
applications enhance information flow between production and sales forces
to improve sales force productivity. Workgroup communications and electronic
publishing of internal business information are likewise made more
