Mass-spectrometer users were developing instruments for their own purposes on a lab-by-lab basis, modifying and experimenting with them at a rapid rate.
Feedback from the field and effective communication about needs and problems were critical to CEC's success in building and marketing mass spectrometers.
Sibyl Rock was engaged in developing the instruments and the procedures for their use.
She was also a key person assisting Consolidated's customers in the use of those instruments and techniques, including the use of Cliff Berry's analog computer.

Rock understood the technical aspects of how the instrument worked and the mathematical aspects of the calculations it was supposed to compute.
Because she worked closely with CEC's customer base, she also understood the instrumentation needs of CEC's growing list of customers.
Rock collaborated with Harold Wiley, manager of chemical instruments, to review both old and new instruments, assessing their operational status and identifying needed improvements.
Rock continuously drew upon her knowledge of the latest methods used by customers and their critiques and problem reports about the instrumentation, to improve CEC's products.
