Probably the single biggest category of negotiations that we do is with our existing customers and our new prospects at Responsys. Again, all over the map, just two observations I would make that might be somewhat definitive about my approach is, 1) discovery up front about what someone’s expectations and what they want to achieve, is by far the most important thing you can do. If you go into a discussion with a great knowledge of what you want but not very much knowledge about what your prospect wants, it's just lame. It's bad preparation because of course you know what you want. So, I really think preparation is important. One of the things you should realize is that, if it's a new customer, someone's been in the sales process and they should have done a good discovery about what the company was going through, what their business objectives were, how they measured success.

That's number one. If you know what they want, that helps a lot. Two is being comfortable on what point you have to be firm on. I think you'll find that the vast majority of people that have made it - by the time I get involve in a discussion, they pretty much decide that they want to work with Responsys.

If you blur it, you set yourself up for later dissatisfaction. So, if I say, "I might take the price a little lower but I'm not sure." All the other person just heard is "if I don't get the price lower, I didn't get the best thing I c...
