On-demand

On Demand Software Delivery describes software delivered to the customer via a network (similar to the internet) as a service. This was originally a revolutionary concept in the late 1990’s. The software market is now in an evolutionary stage as businesses and the software vendors serving them become serious about "on demand software delivery". The current market has proven that "on demand delivery" is in demand now and demand will grow substantially in the coming years. Research firm IDC predicts that by 2008, subscription license revenues will hit $43 billion worldwide, or 34% of the total software market.

On Demand Business is the current (2005) slogan of IBM. The IBM On Demand glossary [1] gives the following definition of an on demand business: A company whose business processes—integrated end-to-end across the company and with key partners, suppliers and customers—can respond with flexibility and speed to any customer demand, market opportunity or external threat. An on demand business has four key attributes: it is responsive, variable, focused and resilient.
