Direct knowledge of the underlying science is invaluable, and Quintessa staff include physicists, chemists, geologists and environmental scientists, educated to MSc and PhD level. But it is often the case that it is necessary to turn to leading scientists. Quintessa maintains a network of highly respected specialists who can advise on specific aspects with authority. We also understand the value of 'synthesising' what is often a lot of detailed information into what is most important. We seek to distil the key facts from large amounts of information, as well as highlighting the most important uncertainties. Methods such as FEP (Features, Events and Process) analysis can be very powerful tools for this.
