The numbers aren't intended to be particularly accurate nor would they be presented as such – it's just a way to get people to realize that lots of little frustrations add up to significant money.

we’ve shown our potential customers also how to speed people up with or social-knowledge tool (~2000), but I’m deeply suspicious with numbers. They communicate precision when I have the feeling there is none.

You're right, you can massage the numbers – the key is to *show* the client how you'll save that time. We quite often hand over the keyboard in demos so that people can try doing the things they do every day that frustrate them and slow them down. Once we get people to take a good look at our product we have an amazingly high rate of sale. Admittedly, we also happen to solve one of the biggest frustrations for end users – the editor. There aren't many areas that are as frustrating to users and that they spend so much time using to make that calculation obvious.

“Conservatively I’m going to assume that we can save each one of these people 10 minutes a day.”

and have been doing the same ROI considerations. But I never found them very convincing. You usally
can massage the numbers as you see fit, for example “people 15 minutes a day.” Is this wrong? Right?
It makes a great difference in the sum if you use 10 or 15 minutes.
