This article provides a conceptual overview of task analysis, which is an inherently multimethod approach. The authors present the method as a step-by-step illustrative template for researchers who seek to develop qualitatively rich models of change and quantitative measures that correspond to these change models. The current article provides an epistemological framework to develop both descriptive and causal models of change. It also offers a comparison with other methods of inquiry that are exclusively qualitative in nature and do not explicitly highlight the use of theory in model development. In addition, the authors describe recent developments in task analysis for dynamic modeling. In tandem with this, they articulate advances in the relationship between task analytic construct development and measurement development.
