Abstract:

The writers at Software Publishing Corporation faced the challenge of reducing the page count of their manuals by more than 50%—without sacrificing quality, extending the schedule, or starting from scratch! They found that approaching this daunting task from several different directions at the same time proved to be the most effective. While the following tips apply primarily to DOS and Windows software manuals, the tips are a good starting point for streamlining any documentation set. The benefits include cutting dollars from the per unit cost of goods and promoting greater customer acceptance of documentation as a learning tool.
