There is too much variation

Printers – Oil Filled Radiators – Phones – Inks – Cleaners  –


Printers :-

One manufacturer is advertising 6 different A4 models…

I had a Canon PIXMA 6550 until it died – I had to buy a Canon PIXMA 6850

Same printer but INK is Different  –  WHY ????

Think about the manufacturing costs by  “Too Much Variation”

  • New Tooling development costs
  • New Ink development and costs
  • Machine tooling set up costs
  • Assembly change over costs
  • Planning and scheduling issues
  • Quality and NPI planning issues
  • Inventory and warehousing costs
  • Supplier issues and extra cost to suppliers
  • Delivery issues and extra costs related to deliveries
  • Shops NOT having what the customer actually wants

The more variations made : –

  • The slower the manufacturing process –
  • The more manufacturing problems there will be –
  • The more rejects and scrap there will be produced –
  • The more difficult the customer will find it to choose –
  • The customer will NOT buy, “Frustrated”

Think about Mavis in Arkwright’s Shop.   –  2″  is too much choice !!!

Oil Filled Radiators:-

One manufacturer is advertising 12 models.

  • 0.5kW, 1.0kW, 1.5kW, 2.0kW, 2.5kW
  • 3 years guarantee, 5 years guarantee, 10 years guarantee,

WHY ??????

Henry Ford said:-

“You can have any colour you want as long as it is black”

Cars came of the production line every 60 seconds… “PROBABLY”

  • and they were cheap…
  • and they were  ‘Fit For Purpose’
  • and they were produced, ‘Single-Piece-Flowline’

Edwards Deming said:-

Adopt the new philosophy.

  • Design products and services to meet customers’ needs.
  • Put your customers’ needs first, rather than to competitive pressure.
  • Be prepared for change in the way business is done – Leading, not simply managing or reacting.
  • Create your quality vision, and implement it – “Fit For Purpose” not cheap and nasty.
  • Provide support and resources so that production levels and quality are achievable.
  • Look at how the process is carried out – Not just numerical targets.
  • Measure the process rather than the people behind the process.
