If you have to create a written report in PowerPoint, here's a good discipline to enforce on yourself for clarity and flow:

Write the headlines on each page in such a way that if they were the only things read, your audience would get the report's main messages.

Since many readers will do little more than a quick scan of the document, this approach creates a greater likelihood you'll get your points across to both skimmers and those who do spend more time with the report.
