Abstract:

Single sourcing sounds good, but can you justify it in your organization? Reducing the need to maintain multiple versions of content produces real savings and improves return on investment (ROI). On the other hand, implementing single sourcing can be expensive and slow, and information developers will be on the spot to continue delivering content through every stage of the process.
