ABSTRACT Task analysis (TA) can contribute to work systems design, accident investigation, risk assessment, human error identification, planning, and training. Despite the advantages of existing sequential hierarchical methods, they decompose tasks into their structure focus on order in which are accomplished. They do not trace all interactions among elements/subtasks/operations at different levels. As complexity increases, keeping track may result poor, unwanted outcomes. This research introduces a approach TA that decomposes constituent functions, describes functionality overall system, traces (dynamic nonlinear) highlights role functional variability forming emergent is called task (FTA). A case study nursing was used demonstrate suitability FTA approach. The findings this show contributes modeling by building nonsequential, nonhierarchical model complex considering dynamic, nonlinear functions. also description explaining ways be It increases understanding, interpretation, how changes conditions shape good/acceptable poor/unacceptable complement adding some aspects, including functionality, nonlinearity, dynamics, emergence, does normally consider. highlight deployed as an alternative (or complement) other methods.
