Systems Engineering Development Framework
The Systems Engineering Development Framework guides practitioners through the steps to build a successful career in systems engineering at NASA, identifying the APPEL KS courses and development activities that can support them and grow their competencies as they move from discipline engineer to subsystem lead, project systems engineer, and finally chief engineer. Terminology and responsibilities can vary by center: In cases where center titles differ from those listed, focus on the substance of the role to find appropriate learning and development opportunities.
