What is Informational/Instructional Design?

Ahh just like that other post I did, this seems like one of those topics that almost answers itself. However what is it really? Well in short the designing of a piece which informs the user in a simple yet effective manner. Like other design the layout of an informational design piece is important, as is any use of logos or brand names, however the information be it visual, audio or language based must be recognizable and be able to provide the end user with the information they require. It is important that the end user of an information design piece be considered when designing an information piece, because if they can not understand it then the design has essentially failed as is mentioned by Erik Spiekermann (2002). Instructional design is on the whole quiet similar however instead of informing the user of something, it instructs them on how to do something. Again the ability of the instructions to be displayed in a way that makes them understandable for the user is the key issue, while layout and style take a secondary position. However in saying that should the layout be confusing or unappealing in either situation the user may potentially choose not to use the design, or may not be able to locate it.
