One challenge in promoting an organization-wide change is tuning the message details correctly. When different people need the information at different times, and in different detail levels, the messages can become complex quickly. In this case for example, we had some technology users with compressed files and some with none. We had some users who were responsible for multiple computers. All had to migrated on a manageable and orderly schedule.
Our response was to develop a critical path to change that everyone had to follow with corollaries for special cases, like multiple computers. The images did some of the lifting for comprehension so we could use less copy overall.
The copy that was needed was left editable in PPT while the images were refined to tell the story with almost no reading required.
The final version of the PPT can be seen below. If you have a complicated change project to communicate, consider using visuals to help engage audiences and speed things along.
