The DITA 2006 conference has started its regular program. Dave Schell, the keynote speasker, presented some IBM experiences with publishing, outlining the costs of some of the previous ways of publishing product documentation, how those experiences informed on the design of DITA, and how the DITA model has brought about specific savings on several projects that have had one or more publishing cycles by now.

Cost avoidance is one of the key issues that Dave discussed. With traditional publishing, the cut/copy/paste penchant of writers was identified as one of the main causes for increasing the amount of review and update as various information sets "forked" from some original version.  In moving to a topic-oriented architecture, one team was able to relegate up to 80% of its information as "common", now completely out of the picture for ongoing review and translation and other handling. Another team working on a completely different product got up to 77% common reuse at the topic level (including some conref reuse as well--phrase-level reuse by reference).
