The first review of the proposed idea was done inside the R&D group (see Chapter 2, Section 2.2.1). It was shown in that review that the process can “make sense,” did correspond to a real need, and, on the face of it, was not scientifically incorrect. As a result of these early consultations, a “green light” was given to the promoters’ group for the commissioning of the literature survey, for the preparation of this preliminary process working definition and for their formal presentation for a second review in a larger forum.
