Research Methods

Hierarchical Decision Modeling (HDM)

HDM is the primary methodology used in the research projects conducted by the Strategic Decisions Research Group. A hierarchical network of decision elements is formed by disaggregating the strategic decision into cascaded levels, then re-aggregating the decision by evaluating the impact of each element on the elements at the next higher level. Quantified expert judgments are incorporated into the evaluations. The results of HDM are the relative values of the decision alternatives typically listed at the bottom level of the hierarchy. Sensitivity of the final decision to changes in government policies or organizations’ objectives, goals and strategies are tested.

HDM is frequently combined with an optimization model to allocate resources to the alternatives consistent with their relative importance to the organization’s mission.

Process Modeling

Discrete and continuous simulation methods are used for modeling the consequences of strategic and tactical decisions and the interactions among the internal and external decision variables. Impacts of the changes in the internal and external environments are analyzed

Empirical Research

Multivariate statistical analysis is used in large-sample studies for conducting descriptive research to evaluate best practices or. Content analysis is utilized in interview-based studies for developing grounded theory.
