PowerPoint templates in big companies are a mess. When thousands of people start sharing PowerPoint files it will take less than 3 months for a corporate template to be vanished due to the many personal modifications and mistakes people make. Here is a survival guide.
- Create a simple template
- Use a PowerPoint expert to create it, not an Adobe Illustrator master, because you need to know how to set default colors, shapes, text boxes, page numbers, left-to-right orientation, etc.
- Create some sort of a box of drawing guides to limit the canvas and leave white space around the edges. Many people might ignore it, but they will have a mental urge to put things inside that box. Put the drawing guides on the master slide so they can't be moved by accident.
- Keep it super simple, I would go for one title slide and one regular slide maybe a separator
- Teach hygiene (this is the hard part). Ask employees every time they create a new presentation to start with this template. Every time. Even if they want to reuse 90% of an existing deck, have them open the clean template, copy paste the charts from the old file into it and save the file.
I wonder whether it is possible to do the hygiene thing with a macro button in PowerPoint automatically, it must be.
Given the above mess, you will understand why it is not possible to modify the slide template in my presentation app SlideMagic.
