A technology demonstration or demonstrator model, informally known as a tech demo, is a prototype, rough example or an otherwise incomplete version of a conceivable product or future system, put together as proof of concept with the primary purpose of showcasing the possible applications, feasibility, performance and method of an idea for a new technology. They can be used as demonstrations to the investors, partners, journalists or even to potential customers in order to convince them of the viability of the chosen approach, or to test them on ordinary users.
Technology demonstrations are often used in the computer industry, emerging as an important tool in response to short development cycles, in both software and hardware development.
Demo Slam, a website from Google Inc., as launched with the slogan "Bring your creativity. Bring your tech. Just bring it in general, fool! Demo Slam is here!", was a large collection of technology demonstrations uploaded by users, and some of the Google executives as well, which will go to the 'Contender'.
Sales Engineering staff, often bearing the title Sales Engineer or Presales Consultant, will prepare technology demonstrations for business meetings or seminars to show capabilities of business products. This can include both software and hardware products, and can show multiple products integrating together. Usually a demonstration is less than a Proof of concept, but can come some of the way to showing how a business project may be justified. Large companies with tens or hundreds of Sales Engineers will often have a team who specialize in the production of demonstration systems and plans.
