IBM User-Centered Design for the Documentation Designer 
The user-centered design of documentation is an aspect of product design that has often been under-emphasized. Difficulties inherent in documentation design include obtaining user, feedback to high-level design objectives; extracting user. feedback specific to a product’s documentation. rather than to the product as a whole; and managing the various resource constraints inherent in product development. IBM User-Centered Design offers a solution to these difficulties by employing a set of user feedback methodologies from which the documentation designer, a member of a multidisciplinary design team, extracts pertinent data to set design objectives and follow through to low-level designs.
