A synthesis reaction or direct combination reaction is one of the most common types of chemical reactions. In a synthesis reaction two or more chemical species combine to form a more complex product.
A design review is a milestone within a product development process whereby a design is evaluated against its requirements in order to verify the outcomes of previous activities and identify issues before committing to-and if need to be re-prioritise-further work.
The Detailed System Design translates the functional design requirements specified in the General System Design (GSD) into a detailed set of system requirements; this includes detailed system flows, program specifications and database specifications that are required to construct the application.
