P3P3 — Mid-Level Professionalhigh0.90approvedglobalv1

Focuses on the design, analysis, and development of mechanical systems and components — leveraging parametric CAD modeling, engineering design calculations, and simulation (FEA, tolerance/interference analysis) to take products from concept through manufacturing release. Distinct from sibling electro-mechanical/mechatronics focuses (which center on integrated electrical-mechanical control systems, PLC ladder-logic, robotic actuation, and instrumentation) and from drafting/CAD-technician focuses (which center on detailing and documentation rather than design ownership). This focus owns the mechanical engineering discipline: structural design, design-for-manufacturability, failure investigation, and architecture of mechanical solutions. NOTE: the source evidence describes a four-tier progression (Junior 0–3, Mid 3–8, Senior 8–15, Principal 15+); the P6 and P7 bands below extrapolate the single 'principal' evidence bucket and should be validated against the function's actual top-band scope before publication.
