“Reduction of work-in-progress” is one of the core heuristic approaches for reducing production cycle time according to modern production management theories. However, traditional management sees production as a transformation of inputs and outputs and, thus, usually ignores the large quantities of waste generated by excessive work-in-progress. In this context, this research has investigated the degree in which English and Brazilian construction companies currently apply this heuristic in construction. The analysis of empirical evidence confirmed that “reduction of work-in-progress” is not well understood among construction managers and there is great misunderstanding regarding the actual effects of work-in-progress on cycle time. The high process variability, the sequential mode of production and poor interface design between processes were major factors contributing to the poor performance of case studies in this respect.
