Developing the Theoretical Foundations section requires a step-by-step approach as described in the table below. To begin, researchers identify the models, theories, or concepts that are relevant for the problem statement. For a quantitative problem statement, researchers identify a model or theory for each variable. It is also important to ensure a validated instrument or data source exists to collect the data for each variable.

If the researcher were trying to determine whether there is a relationship between spirituality in leaders and the organizational climate they develop, they would need one model for the variable, 'leadership spirituality,' and one model for the variable, 'organizational climate
