Design for Manufacture

Lean companies

  • Have manufacturing people as members of the product development team with an effective voice in manufacturability issues
  • Provide mechanisms for design and manufacturing jointly to plan for modular assembly, cellular manufacture, mass customization, introduction of new technologies, quality and reliability, supplier requirements, etc.

Traditional companies

  • Show the manufacturing people the product design too late for some of their suggestions to be implemented
  • Decline to spend enough time with manufacturing to understand its issues
  • Use workload as the reason designers cannot spend more time with manufacturing
  • Resist using common components

Benefits of Lean

  • Produces product designs that can be manufactured easily and meet targeted quality, reliability, cost, and schedule goals
  • Reduces expensive late engineering change orders
  • Facilitates smooth ramp up to full production
  • Speeds the entire product development process by eliminating surprises and fumbles

"The great genius of Taiichi Ohno and his Toyota colleagues in post-war Japan was to see that Ford had discovered only the special case for lean thinking - high production volume with zero product variety, infinite model life, and completely stable demand."

"The PC uses fewer screws (four screws in the whole box vs. 15 in the previous design), instead using snap-in, snap-out parts, which Dell claims improves serviceability and decreases manufacturing times, lowering the overall cost to build a PC. Dell can manufacture 40 percent more of these small systems on the same production lines as standard-size OptiPlex computers."

"Dell says the Optiplex GX150 can also be more easily serviced. The PC has a clamshell-like design that allows it to be opened like a book for servicing. Inside the PC, Dell has implemented a color-coding scheme, which it says will make servicing much easier. The company has color-coded everything, including labeling all of the user serviceable items, such as memory, hard drives and graphics cards, with green."
