Shailendra had attached one on this topic in 2007 and people have commented on that. https://www.citehr.com/26154-ppt-com...y-mapping.html
One of the comments applies to you too.
Alibaba10 had commented thus.
Very well done presentation.
Only thing I'd suggest is that you hsould put less material on eah slide,-- only key points to serve as cues, not the entire text for the presenter to read out.
'Also, if you can add few graphics, it would make it more interesting.
keep it up.
Same applies to you.
