A national specialty sales training department for a large biopharmaceutical company was challenged by its stakeholders to develop a structured onboarding process that improved consistency and time-to-proficiency, while leveraging an online curriculum and peer mentoring. Prestera FX was asked to develop the mentoring framework, onboarding materials for new hires and their peer mentors, as well as training for those peer mentors. We established a mentoring skills framework by benchmarking key success factors for mentors, then used that model as the basis for the onboarding materials and training. The process, tools, and best practices were implemented through an elearning module and in-person workshop.
