Relationships with Our Customers

Based on the "Customer First Principle", Kubota aims to offer products, technologies, and services that exceed customers' needs at a speed beyond their expectations. We seek what we have to do to maximize customer satisfaction based on the "Onsite" approach policy perspective, which includes going to the actual site, seeing the product, and confirming actual facts, and put into immediate action whatever we can.

Kubota will continue to promote initiatives in all aspects of its operations, including development, production, sales and services, aiming not only to improve sales and profits, but also to establish itself as "Global Major Brand" trusted by a maximum number of customers and capable of making a maximum contribution to society.

Production / Quality Control

Strengthening Production Systems

Building a global production system

In order to achieve the goal of becoming a "Global Major Brand," Kubota has established production bases around the world in locations close to their respective markets, with the mother plant supporting all the other plants in order to secure consistent quality. Furthermore, Kubota is promoting the deployment of the Kubota Production System (KPS) at each of its bases and implementing initiatives to raise the QCD level throughout the entire supply chain.

Deployment and dissemination of the Kubota Production System

Kubota Production System
  • Kubota’s basic principle for manufacturing
    Kubota aims to achieve manufacturing that impresses customers by offering products and services that exceed customers’ needs at a speed that exceeds their expectations.
  • Kubota Production System
    Kubota Production System (KPS) is the fundamental concept and perspective of the Kubota Group’s manufacturing.
    While adhering to the basic philosophy, KPS is based on “just-in-time” and “automation” and continuously pursues thorough elimination of waste.
In 2016 Kubota started deploying KPS throughout the company.
  • In Japan, activities for dissemination began from four major machinery-related sites (Sakai, Tsukuba, Utsunomiya, Hirakata Construction Machinery), and have now spread to 19 sites including other sites and affiliated companies.
  • Kubota will expand these activities to overseas. Kubota will also broaden the range of its KPS activities from plants to both upstream and downstream of its supply chain, such as suppliers, sales, dealerships, and logistics.

Maintaining and Improving Quality

Quality control in design and development

Photo:A design reviewA design review

Kubota endeavors to prevent quality problems, and a representative activity in this effort is the initiative to strengthen design reviews (DR). Integrating the DRBFM*1 approach, we discuss, test and verify even the smallest item changed when developing new products, and reflect the results in the product in order to prevent quality problems.

*1 DRBFM is the abbreviation for "Design Review Based on Failure Mode," a method of preventing potential problems from arising by focusing on changes in design and development.

Quality audits

Kubota periodically conducts quality audits for the purpose of providing its customers with even better products and services.

Raising awareness of quality

In November 2016, Kubota held a Quality Forum led by a visiting lecturer as an awareness-raising activity for improving quality.

The lecturer spoke about the value creation and quality assurance necessary for sustainable growth of a company, based on the theme “Implementation of the Quality-Creating Management at Toyota—to continually satisfy customers.” Around 400 people attended, including management, and renewed their awareness of the importance of quality management.

Ensuring Skills to Maintain Customer Satisfaction

Kubota holds the Kubota Group Technical Skills Contest

Every year with the aim of fostering a sense of unity and improving technical skills throughout all companies in the Group. During the contest for fiscal 2016, a total of 238 contestants from six countries (26 bases) put their technical skills to the test in 15 categories, including lathing, welding and machine maintenance. In this contest, representatives of suppliers who had won the preliminary contests participated for the first time.

This contest provides an opportunity to evaluate the skill levels and initiatives of each base and motivate the contestants to hone their skills even further. In FY2017 and the subsequent years, Kubota will continue to hold this contest as an opportunity that help further improve the manufacturing capabilities of the entire Group.

Fostering manufacturing personnel to establish Kubota as a Global Major Brand

Kubota promotes the Kubota Production System (KPS) at its domestic and overseas bases with the aim of becoming a "Global Major Brand." The "5-Gen Principle" is implemented to achieve site improvements necessary to advance KPS. The 5-Gen encompasses a philosophy based on the actual site (Genba), actual things (Genbutsu), actual facts (Genjitsu), principles (Genri) and basic rules (Gensoku). It is a place for fostering employees who will implement improvements aimed at closing the gap that can arise between the actual and the ideal. Approximately 470 people attended this training program in fiscal 2016.

Starting from 2014, Kubota has introduced the 5-Gen Dojo at its major overseas sites, with the goal of strengthening manufacturing capability and localizing human resource development.

In May 2016, Kubota established the 5-Gen Dojo in Thailand, where human resources capable of strongly promoting improvement are developed through lectures and on-site improvement training by local instructors.
