This paper is based on the operationalization of flows and identification of wastes along these flows. Ideas are derived from this article for why and how to measure the flows in order to minimize wastes. The aim of this paper is to present the different existing flow concepts, as well as the characteristics, principles and preconditions proposed by the Lean authors for the sound process. For that, concepts of flow in the construction management field, from logistic and lean perspective, are presented in order to identify core principles which support the measurement of the flow and its potential wastes. In addition, three methods for the measurement of the flows are described. The present paper contributes with a better understanding of the nature of flow, and in particular, the process flow, the workflow and the physical flows, and their measurement.
