This document outlines a design specification for adding online video product demos to Centauri Systems' website. The specification addresses the user experience of reviewing Centauri's four products, selecting a product, viewing information and a demo video about that product, and then choosing to purchase the product or learn more. It was created for executives at Centauri Systems and engineers at Alpha Multimedia Company to design and develop the new website functionality. Representatives from both companies will review the specification to confirm the design and create a detailed low-level design.
