Question: I am using Tridion 2009 SP1 for a client, we have jsp pages and vb script. Our client wants to switch to Tridion 2011 and have told to investigate Experience Manager. I tried searching on sdllivecontent but could find anything with this word. Can anyone direct me what actually is Experience Manager so that i can get back to client and estimate the efforts required when i migrate to Tridion 2011

Answer: 
Experience Manager is the product formerly known as the SDL Tridion User Interface (UI) update, formerly known as SiteEdit.

You can find information on Tridon World for UI Update 
(<https://www.sdltridionworld.com/downloads/documentation/UIU4SDLT2011SP1/index.aspx>) if you have access, as well on SDL Live Content
(<http://sdllivecontent.sdl.com/LiveContent/content/en-US/UIU4SDLT2011SP1/concept_EDC411EF58BD4700A8B6BD996AB102F3>).

I suppose the reasoning behind the re-renaming of the product is due to its becoming more integrated into the main Content Manager Explorer interface.
See the naming history in the other answers, but the initial community posts were back when it was called New User interface.

In terms of project scope, **be sure to include time to work with the client to create and help setup their prototype content, content types, and page types**. These features were already a part of SiteEdit 2009, but are now easier to configure.

Page and content types allow authors the ability to create new pages and content; they're based on business needs but need IT or development to set them up.
