I have also attached (page 3) a list of "data quality objectives" that I have successfully used to help define the "what" and "how" of an analytical program. If possible, please call me before tomorrow's teleconference. Feel free to share the attachments with anyone interested.

Why is the data needed? How will the data be used? How sure do we need to be? What is the minimum data to answer the questions? What is the cost of being wrong (right)? Can the question be answered with existing data? What are the time and resource constraints on data collection? What calculations, statistical or otherwise, need to be performed on the data in order to arrive at a result? R&S 143520
