Many of us share Atlas's assessment of the user edit as a very powerful and inexpensive tool for improving both products and product documentation. Certainly, there is extensive scientific evidence that methods like the user edit can provide valid and detailed information about human performance (Ericsson and Simon, 1991). Karen Schriver has accurately outlined the role that Atlas's article played in the extensive developments that have occurred in document design since the 1980s.
