3. Key Messages and Themes Creating scalable DITA projects

4. March 2007implementingDITA™: Setting the Stage4 Key Messages Increased complexity can result in both: - A significant increase in benefits - A significant increase in challenges Take the time to architect and plan well at the simple stage, so your more complex projects are “elegantly sophisticated,” not “a complex mess of spaghetti-docs.”

5. March 2007implementingDITA™: Setting the Stage5 Themes: Architecture and Content Benefits of complexity: sophistication! –Higher quality content –Opportunities for content reuse, collaboration, and customization –Opportunities for content integration and reuse (for example, documentation and training material) Challenges of complexity –Need for tight, centralized control and close collaboration

6. March 2007implementingDITA™: Setting the Stage6 Themes: Technology, Logistics Benefits of complexity: sophistication! –Faster response time –Tighter integration with product and related software (e.g., translation memory) –Ultimately cheaper Challenges of complexity –Technical complexity can increase beyond a typical writer’s comprehension –Potential loss of control of the process and tool choice –Significant start-up costs (time and $)

21. March 2007implementingDITA™: Setting the Stage21 Complex Project: Product Skytide Analytical Platform (www.skytide.com)www.skytide.com OLAP tool: “Enables the analysis of nonrelational data using traditional Business Intelligence techniques without requiring transformation of the data into relational format” XML-based (written in Java) Consists of Designer, Server, and SDK Works with DB2 9 (Viper) Can do business analytics and content analytics

22.

23. March 2007implementingDITA™: Setting the Stage23 Complex Project: Doc (continued) Target publishing environments –XHTML –PDF –JavaDoc reference material –Future: Context-sensitive help (on object properties) Specialization: Bookmap Customization (ditaval) –Windows/UNIX –PDF/non-PDF

24. March 2007implementingDITA™: Setting the Stage24 Complex Project: Doc (continued) Processing reuse –Three-tier build process: (1) product build.xml (2) generic doc build.xml (3) separate Ant script for each doc –Can build a complete release package (including docs) any time –Doc “unit test” takes place outside the top-level product build Informal content reuse –Shared content between documentation and training material –Estimated savings: 50-75%, 2 days to formalize 2-day training class

38. Lessons Learned The importance of “setting the stage”

39. March 2007implementingDITA™: Setting the Stage39 Lessons Learned Do at least two simple prototypes before tackling a complex project First prototype (3-4 weeks) –All new content (concepts, tasks, reference topics) –At least 2 output targets –2 tiers –Up to 50 topics –1-3 people (one being an information architect and one who is technology savvy) Second prototype (6-8 weeks) –Some new, and some migrated content –Focus on reuse, customization, specialization, linking strategies –3 tiers –Up to 100+ topics –4-6 people (one architect, one technologist, one editor)

40. March 2007implementingDITA™: Setting the Stage40 Lessons Learned (continued) Apply the lessons learned doing your simple projects to set the stage for your subsequent complex projects Enjoy your future successes!
