Thank you for the presentations today. I certainly appreciated the information.
I'll just pick up from where Mr. Arya left off.
You talk about rationalizing, about looking at our existing programs. One of the frustrations I've seen since I got here is the lack of measurements, or at least publicly disclosed measurements, of the success. What are the measurements? How do we determine whether a program internally is effective or not effective? What criteria do we use?
Could you tell me the three most important criteria you would use to determine whether a dollar spent is worth it or not?
