Our customers’ trust
Our Quality Assurance Department plays a central role in our “Attack V”
and other continuous improvement initiatives, with the goal of
making sure that our craftsmanship delights our customers and
convinces them to put their trust in us.
We strive to improve by continuously refining our quality, cost, and service.

As a manufacturing company, we aim to establish a CS (customer satisfaction)-oriented management system with the fundamental goal of creating satisfied customers.
This system is implemented through initiatives such as our Attack V and QCDDS improvement activities.



In order to consistently provide reliable products that delight our customers,
we established a Quality Assurance Department to carry out our “Attack” and other quality initiatives.
Goals and plans for these initiatives are set at the beginning of
each fiscal year.
(zero delivery time failures) by 2016.


Craftsmanship in our processes▶We aim to create mechanisms to prevent defects via jigs, tools, equipment, and error-proofing. We strive to build systems to guarantee operation and maintenance.
(3Z assurance activities)
Understanding that how we respond to a defective product can make or break a customer’s trust, we identify the causes of defects by FTA analysis, and treat our defect countermeasures as something to be managed by means of process quality matrices, work standards documentation, written inspection standards, 3Z assurance revisions, and error-proofing.
For newly-ordered innovative products, we work in project teams to meet customer quality requirements based on pre-production quality assurance activities (supplier master schedules).
Day-to-day management▶We use verification mechanisms to ensure the required quality characteristics in the initial-, middle-, and end-stage products, and to measure our process capability (Cpk).
Training-related▶We strive to improve the skills and quality of our personnel to foster a “community of craftspeople”. Priority management items are enforced repeatedly and routinely (at regular intervals). (Education and training)
We promote standardization of our work procedures, molds, jigs, and tools. (7 goals of standardization)
6-1▶Determine the correct way of doing a task.
6-2▶Standardize the work procedure so that it can be done the same way no matter who is doing it.
6-3▶Clarify the responsibility for each task so that the work proceeds smoothly.
6-4▶Make sure those who are new to the job are able to learn the correct way to do the work.
6-5▶Maintain skills and techniques, and ensure that the importance of these traditions is passed down in order to nurture the next generation of craftspeople.
6-6▶Clarify the contents of the work, and use this as an opportunity to further develop skills and techniques.
6-7▶Establish a “safety first” work environment that enables work to proceed safely.
To foster personal growth, we encourage continuous improvement in all operations, and we are never satisfied with the status quo.


VE (Value Engineering).
The Japan Quality Award is an awards program that comprehensively evaluates
a company’s human resources, technology, intellectual property, and other capabilities on a 1,000-point scale.
Busyu Kogyo hope to earn a Japan Quality Award by exceeding the ISO evaluation criteria.
・ Improve employee satisfaction
・ Transparency of salary system
・More full-time employment

To promote improvement activities,
we have been choosing a theme every five years since 1985,
with the goal of quality improvements that will lead to greater customer satisfaction.


“Aim for A rank” is an important initiative to provide 100% assurance while we continue to enforce our 3Z assurance even more rigorously. We will continue to win customer trust in our products by building a framework to carry out in-process quality assurance during single-piece flow production, without unnecessarily increasing the number of man-hours devoted to our 100% assurance actions.

Automatic 100% inspection
without human judgment

Checks using jigs and tools

Visual checks
・More in-house production of Busyu products
・Production with zero free time costs
・Zero defects, zero inventory,
time-shared delivery
・Review of production methods for
inventory minimization


・We will be sure to provide service that satisfies everyone, including customers, partner factories, suppliers, and our own people.
・We will use the “balanced scorecard” system to promote transformation “from the quality of the goods to the quality of work” in order to deepen the integration between our daily activities and our ISO 9001 and ISO 14001 activities.
