A comparative study in terms of adequacy and rigor between FEM, direct stiffness method and FDM in analyzing composite beam problems has recently been carried out by Ranzi et al. (2006).
This is exemplified by Spiegel et al., who describe moving from research for inquiry's sake to impact-oriented investigation while maintaining rigor in methods.
The Common Rule, WHO guidelines, and consensus statements have sought to distinguish research and QI based on the rigor of methods (internal validity) and generalizability (external validity) of the findings [ 4– 6].
Pursuit of the Ecuador Eco-Health initiative was a very ambitious undertaking – requiring moving from unidisciplinary to transdisciplinary teams, combining intercultural perspectives and moving from research for inquiry sake to impact-oriented investigation, while maintaining rigor in methods.

Defining the intended application of the biomarker (for example, will it be used for internal decision making, exploratory research, or as a diagnostic) will determine the rigor of method validation and assay documentation needed.
However, the qualitative and quantitative approaches meet the standards of rigor for both methods even though the integrated design requires structural changes in the methods themselves that may become harder to meet [ 29].
Given the rigor of quantitative methods and the subjective information gained through qualitative inquiry, the use of mixed methods is increasingly common in the assessment of HRQOL [ 51].
