Follow departmental procedures and standardised work practices while actively contributing to their ongoing review and improvement.

Manage planning activities for New Product Introductions (NPI), product obsolescence, and the transition to in-house manufacturing by ensuring all production planning MRP parameters (e.g., production pools, routes, serialisation, and related settings) are correctly configured to support a seamless production launch.

Liaise with the Documentation & Data team to ensure new products are accurately configured across all warehouse entities prior to NPI release.

Coordinate warehouse stock run-down activities for obsolete products by balancing customer demand with warehouse replenishment, adjusting inventory parameters, and managing component consumption to minimise excess stock.

Participate in obsolescence review meetings, providing projected warehouse depletion timelines to support uninterrupted product availability, and communicate inventory run-down progress to Production, Engineering, and Machine Shop teams.

Contribute to cross-functional projects that impact production planning, including new product introductions, transition to in-house manufacturing, product obsolescence, and changes to processes, components, or manufacturing routes.
