To do so correctly, it is vital to understand how the results of techno-economic studies are produced, what can be inferred from them, and where the potential weaknesses of the study are. One method specifically developed to evaluate and communicate the strength of quantitative science for policymaking is the Numeral Unit Spread Assessment Pedigree (NUSAP) method, which includes pedigree analysis to provide a systematic qualitative assessment of the strength of quantitative information and models.
