This research proposed the technique to identify an
appropriate process improvement area from the SPA
result and other factors by use of QFD. Effectiveness
was evaluated based on the real case study in an actual
project. As a result, we were able to confirm concrete
effectiveness to decrease rework within the range of
the proposal.
In the future, while increasing the application cases,
it is required to collect results into database, as
deployment table or a correspondence table, to clarify a
concrete usage method and its effectiveness. In
addition, to save time to create the quality table, by
classifying and patterning, system to re-use quality
table should be considered.
