Decision tree approach for assessing the reliability of the method used for estimating each cost. The colour of the boxes indicates which decision was taken: green when material was deemed as of high reliability, red when material was deemed as of low reliability, blue when taking any decision needs further investigation. The intended purpose of this process was not to evaluate the quality, relevance or realism of the studies performed for providing cost estimates, but rather to assess if the methodology (i) has been reviewed and validated by peers or experts prior any publication, or (ii) if not, whether this methodology was clearly stated and demonstrated.
