THE ROOF OF THE QFD

1
THE ROOF OF THE QFD

• This set of slides is intended to help facilitate
  a group through the development of a roof for
  their QFD, and to translate their understanding
  into a communications plan.
• Please do not attempt to use these slides as part
  of a presentation until you have read and fully
  understood the relevant sections of Managing by
  Design, you know how each slide builds, and you
  are clear on the points you wish to make with
  them.
• There are some associated notes to guide your use
  of these slides.

ROOF OF THE QFD

• Now we have a house with Objectives, Measures,
  Targets, Process and Weightings
• What if everybody works flat out to achieve their
  targets?
• Will this have an impact on the performance of
  other processes?
• Will our processes work together?
• Or will one process negatively impact the
  performance of the other?

THE ROOF

• If efforts to improve process As performance
  are likely to contribute to an improvement in
  process Bs, and vice versa.
• If efforts to improve process As performance
  are likely to prove detrimental to process Bs,
  and vice versa.
• If efforts to improve process As performance
  are unlikely to influence process Bs, and vice
  versa.
• If efforts to improve process As performance
  are likely to contribute to an improvement in
  process Bs, but the reverse is true the other
  way round.

There could be synergy in working together to
achieve this. There should be consultation on the
implications. There is no real need to
interfere. There should clearly be some
communication.

THINKING THROUGH THE ROOF

• Take the seats allocated to your process
  according to this diagram.
• Discuss with the people opposite you the
  relationship between your processes - whether the
  process objectives place you in potential
  conflict or synergy.
• Mark your conclusions at the intersection of your
  processes in the triangle.
• On the basis of this reach agreement on the level
  of communication needed between your processes,
  and how this will be established.
• Move to the next seat on your right, except
  process 10 which stays put
• You have 5 minutes per conversation and then we
  will ask you to move to the next position
