Requirements

  • Essential Job Functions

  • Run time observations and build the standard work charts from them
  • Calculate takt, balance the line, and set the manpower from the balance
  • Design stations and layouts in SolidWorks — to scale, with walk paths and material locations
  • Design error-proofing in so the defect cannot be made, instead of inspecting for it
  • Run trials and DOE to set a capable, repeatable process window

  • Own validation (IQ/OQ/PQ), capability studies and Gage R&R
  • Lead root cause work (5 Why, A3) and close it with verified effectiveness
  • Train Supervisors, Team Leaders and operators — a process is not deployed until they are trained
  • Respond to floor escalations the same shift, at the machine
  • Experience, Knowledge, Skills & Abilities
  • TPS: takt, standard work, jidoka, poka-yoke, SMED, pull, 5S, value stream mapping, kaizen and A3
  • SolidWorks — parts, assemblies, 2D drawings, fixtures and to-scale layouts
  • Standard work charts and how to build them from a real observation
  • Workstation and cell layout — reach, motion, flow, spaghetti diagrams
  • Injection molding process and scientific molding basics
  • Cpk, Gage R&R, DOE and basic statistics
  • PFMEA, control plans and validation for regulated product
