Areas of Focus

Human Centered Design

Founded in design thinking, open thinking, and liberating structures principles, the DSD human centered design approach (ARC-TIC) employs tailored problem framing, innovative solution discovery, and creative adaptability to harness collaborative analytic potential and lead change. DSD applies this approach to internal and external efforts to ensure custom-designed ARC-TIC projects, including concept development, requirements generation, assessment development, remain as cutting edge as the solutions they provide.

Systems & Mission Engineering

Effective systems and mission engineering facilitate readiness and elasticity in the defense ecosystem and ensure the acquisition of systems designed to address critical challenges at the speed of relevance and overcome obsolescence, interoperability, and sustainment challenges. DSD plays a critical role in SE and ME application in curriculum and concept development and acquisitions analysis.

Mathematics & Statistics

DSD has a strong foundation in mathematics and statistics, which are core components of information, data, and decision science. Applications of mathematics and statistics have been used in creating linear regression, classification, and clustering models. DSD has directly applied this knowledge to build metrics, design experiments and surveys, and create probabilistic models for anomaly detection and survivability analysis.

Data Science

DSD possesses a wide range of data science capabilities, spanning from the initial phase of data processing, all the way through to data visualization. Through numerous projects from varied sponsors, DSD has honed these capabilities and can deploy them on a wide range of datasets, in a variety of industries. DSD has developed full scale machine learning applications, on a wide range of algorithms, including traditional regression, neural networks, decision trees, and Bayesian methods. In addition to these applications, DSD is well versed in cutting edge natural language processing techniques, utilizing tools and algorithms such as BERTopic to perform various NLP tasks, such as sentiment analysis, topic modeling, and text classification. Through these advanced algorithms, DSD is able to extract key and unique insights and uncover the meaning behind vast amounts of data.

Social Science

Social sciences offer a rigorous framework to assess complex threat realities. DSD leverages social science models, methodologies, and principles in support of efforts to understand and assess the threat environment the modern operating environment. Using both qualitative and quantitative approaches, DSD produces a range of products from decision models to operational concepts and strategies.

DAU, Department of Defense (DoD)

In response to Congressional tasking under the National Defense Authorization Act of Fiscal Year 2022, the Defense Acquisition University (DAU) leveraged VT-ARC to assess the status of the nation’s innovation and emerging technology adoption training programs for Department government civilian, contractor, and active-duty employees.
VT-ARC defined innovation, created a taxonomy and proposed an analytic framework to identify necessary workforce training components. After comparing numerous service-related approaches aimed at getting new innovations into operator hands, we identified recommendations regarding future capability development.

Human Centered Design Facilitaion DATAWorks 2024

First introduced in 1987, modern design thinking was popularized by the Stanford Design School and the global design and innovation company, IDEO. 1 Design thinking is now recognized as a “way of thinking which leads to transformation, evolution and innovation” 2 and has been so widely accepted universities, including Stanford and the University of Potsdam, offer graduate degrees in the discipline. Related to design thinking, Liberating Structures, are “simple and concrete tools that can enhance group performance in diverse organizational settings.” 3 Open thinking, popularized by Dan Pontefract, 4 provides a comprehensive approach to decision-making that incorporates critical and creative thinking techniques. Founded in these the principles from each of these approaches, the Decision Science Division (DSD) of Virginia Tech Applied Research Corporation human centered design approach employs tailored problem framing, innovative solution discovery, and creative adaptability to harness collaborative analytic potential, overcome the limitations of cognitive biases, and lead change. 5 DSD applies this approach to complex and wicked challenges to deliver solutions that address implementation challenges and diverse stakeholder requirements. This experiential session will provide attendees with some basic human centered design facilitation tools and an understanding of how these techniques might be applied across a multitude of technical and non-technical projects.
