Everybody working in the production process at MMC is individually responsible for guaranteeing product quality.
One problem that we had was that our production systems were not well enough configured to allow each worker
to check the quality of their work. So, to make ISQC a reality, we first reconfigured one of the production lines at our
Nagoya plant. We undertook a large, cooperative study to analyze all the factors that could result in a defect. We studied
what types of operations were performed within each part of the process, what kinds of defects were associated with
this, and what could be done to prevent each type of defect from occurring. Using data collected for thousands of cases,
we worked out what methods we could apply to allow individual workers to guarantee the quality of their work.
Alongside this, we developed and introduced a new system called MICOS, which stands for Mitsubishi Inspection
Data Control System. This system allows each quality check to be recorded and stored. The huge amounts of data
generated can all be managed and accessed through handheld terminals that connect to MICOS through a wireless
LAN system. Each data entry records the person who performs each individual quality check, as well as when and how.
Combined with the new ethos in which each person has a clear responsibility for quality, this system is generating good
results. Naturally, we have also applied it to the GRANDIS minivan.
In addition, QC now plays an active role in our vehicle testing as well. QC function in the production area is involved
in the evaluation of vehicle testing at our technical centers from the earliest stages to ensure that the quality of all
aspects of the vehicle’s operation during development are reflected in the final production model.
The new thinking at MMC is that product quality is something everybody must work to create and preserve. This
atmosphere now pervades the entire process of development and production. We feel as if we must work as a team to
achieve this quality goal, and this feeling spans everybody from those working on the shop floor to the rest of the
organization. The results can be seen in the success of the new COLT and GRANDIS models.
