Interesting debates are ongoing on how to develop practical implementation science competencies that can bridge the "know-do" gap in global health. We advance these debates by arguing that apprenticeship and mentorship models drawn from "art and craft" used in industry is the missing piece of the puzzle that will bridge the persisting gap between academics and real-world practitioners. We propose examples of such models and how they can be applied to improve existing capacity building programs, as well as implementation in practice.
