Abstract
Lean construction (LC) emphasizes the reduction and coping with variability. Nevertheless, a portion of variability is unavoidable, and it triggers manifestations of resilience, at the individual, team and organizational level. This paper compares the perspectives of LC and resilience engineering (RE) of variability. Three criteria are adopted for the comparison: (i) commonalities and differences between the concepts of resilience and making-do, as the last is relevant for the LC view of variability; (ii) types of variability each perspective emphasizes; and (iii) tools for the description of systems, which set a basis for the identification of variability. Concerning the last criterion, a comparison is made between Value Stream Mapping, which is derived from lean, and the Functional Resonance Analysis Method, which is derived from RE. Based on this comparison, learning opportunities for LC from RE are identified.
