This paper first endeavours to compare the original prescription of the traditional conceptual model of productivity and performance with TFV-theory through literature study. This comparison is carried out in the context of construction management. To investigate the differences in practice, two case study sets of data were analyzed. Performance data on each of the 27 tasks was evaluated from transformation, flow and value view. This exercise illustrates how a performance evaluation through the TFV-theory focuses, besides the transformations (T), on the delays and production rate differences (F) as well as on quality or safety performance (V). In so doing, it addresses the possible causes of poor performance, and also the related solutions. These causes and solutions remain invisible in productivity evaluations.
