Deciding on the right mix of portfolio projects is crucial for the organization since poor decisions in its selection affect its value, resulting in a misallocation of resources and missed market opportunities. Despite the criticality of choosing an optimal project mix, portfolio decisions are often made in an equivocal environment where data is limited, resources are constrained, and projects are interdependent. These factors create considerable decision-making challenges and are the impetus behind this study's orientation toward decision styles and the match to its context. Dual-process theory (DPT) references two styles: rational and intuitive. Quantitative and analytical project selection techniques capitalize on a rational decision style. However, the tools are complex, assume the availability of information, and often do not account for project interdependencies. The parallel-competitive variant of DPT asserts that intuition is well-suited for decision-making in such environments. Yet, an intuitive decision style requires experience and can create biased outcomes. Extant literature revealed that combining both styles provides good results since it can counter the adverse effects of each type while exploiting its benefits. These findings led to the following question: To what extent does the decision style of project portfolio decision-makers predict project portfolio success? A non-experimental correlational study (N = 105) that relied upon senior management and C-Suite portfolio decision-makers from US companies was designed to answer the following: 1. To what extent does the rational decision style of project portfolio decision-makers at companies with 500 or more employees predict project portfolio success? 2. To what extent does the intuitive decision style of project portfolio decision-makers at companies with 500 or more employees predict project portfolio success? 3. To what extent do the rational and intuitive decision styles combine to predict project portfolio success for decision-makers at companies with 500 or more employees? The dependent variable of project portfolio success was regressed on three predictors, rational decision style, intuitive decision style, and the product of the rational and intuitive style (i.e., a combined style), using robust, weighted least squares regression. The main model was positive and highly significant (robust F[3, 101] = 74.69, p < .001). Simple slopes analysis revealed that the intuitive style strengthened the rational style, creating a positive interaction effect. The findings have broad implications. First, project portfolio decision-makers utilize intuition, with successful portfolios a predicted outcome. Such beneficial effects align with the parallel-competitive theory that places intuition on par with the analytical mind and holds theoretical significance. Thus, portfolio managers should feel free to apply intuitive judgment in addition to quantitative analytical techniques to portfolio decisions. Doing so can provide the decision-maker with the synergistic benefits of both methods, resulting in superior decisions than would be possible with either style alone.
