If you (restaurant operator) could create the best back office system to improve store performance

Imagine you could crack the whip and get some group of Mountain Dew-energized engineers to create whatever Back Office software you wanted... 

1) What's the most important thing you would look for (in general)?

2) What's the most important thing for labor scheduling?

3) What's the most important thing for managing inventory?

4) What's the most important thing for POS analytics? (What reports would you want to see or interact with)

Thoughts?
