Abstract for: Modeling the I-Corps Program Theory: A System Dynamics Approach to Understanding Translational Scientist Development

IntroductionThe National Science Foundation's Innovation Corps (I-Corps) trains researchers to evaluate commercial potential through intensive customer discovery. While evaluations demonstrate impact, the mechanisms driving capability development remain poorly understood. We developed a system dynamics model explicating program theory for Case Western Reserve University I-Corps@NCATS, identifying feedback loop structures that drive translational scientist capability development during and after this entrepreneurial training program for biomedical researchers and clinicians.
ApproachUsing Stella Architect, we constructed a conceptual model representing eight capability stocks linked through three primary feedback loops. The model simulates a single innovation team over 30 months: 6-month pre-program period (concurrent CWRU Translational Fellows participation), 2-month I-Corps intervention, and 22-month post-program period. Four intervention points represent pedagogical mechanisms. Model structure draws from Kolb's experiential learning framework and empirical I-Corps literature.
ResultsThe model demonstrates three feedback mechanisms: R1 (Customer Discovery Engine), R2 (Capability Development Engine), and B1 (Assumption Correction). During pre-program, capabilities show modest baseline development (translational skills: 0.40→0.44). I-Corps intervention produces clear acceleration (skills: 0.44→0.55). Post-intervention, reinforcing loops drive sustained growth, with skills reaching 0.75, networks 0.40, and humility 0.50 by month 24, demonstrating brief interventions produce lasting effects through feedback dynamics.
DiscussionThe model reveals I-Corps works through coordinated activation of three feedback loops, not individual skill acquisition. Long-term sustainability derives from self-reinforcing dynamics, explaining why brief interventions produce sustained effects. These findings suggest program improvements or adaptations should focus on strengthening feedback loop activation rather than lengthening program duration.
