Lesson of Quality Learned From Experience

In the Alpine Museum located inside our headquarters office, there is an exhibit of a product that was shot with a .45 magnum in 1981. This was back when Alpine had only just entered the American market, and when quality was still inconsistent — the customer who purchased the car stereo was dissatisfied by it, because the cassette inside would not eject properly, so it was returned. Today, it is a symbol for all Alpine employees of our obligation to offer premium quality products and services. It is a reminder that each and every Alpine product we deliver to the market is special from the end user's perspective, and the foundation of Alpine's evaluation in the market.

The Pursuit of Reliable Products

Automobiles operate in a wide range of environments. To ensure the reliability of our products, Alpine conducts testing and evaluation in even harsher environments than real life. In our reliability and evaluation centers, the robustness of our products is tested under various strict evaluation criteria, testing glare caused by sunlight, and durability against sand and dust, as well as temperature, humidity, vibration, shock, radio wave, and sound characteristic tests. Our test course reproduces severe road conditions, allowing us to confirm that even on rough roads, our products still work properly.

Improvement of Quality Inspection Capabilities

As products' technology improves and complexity increases, hard-to-detect defects can become more common as well. We have introduced nondestructive testing, combining high-sensitivity infrared cameras and the lock-in technique*1 at our Evaluation Center, and have put together a top-level inspection system that allows us to quickly and accurately analyze defects invisible to the naked eye, enabling us to improve quality through industry-leading inspection systems.

*1 Lock-in technique: A technique that allows the depth of heat-generating spots and heat sources to be specified in high resolution by adding pulsed micro voltage to the target.

Sharing of Information on Past Problems among Employees

We have established an “Exhibition Room for Important Quality Issues.” We use this room for training to ensure that information on past quality problems will not fade from memory, the most effective way to prevent recurrence. Displays include the actual defective items, descriptions of the incidents that led to quality problems and feedback from the customers that were affected by them.

Quality Management System (Global QMS)

Global standards for the quality management system (QMS) ensure that all departments and divisions at Alpine satisfy customers with a policy of quality assurance, which is essential to the pursuit of business activities.

Alpine has already obtained ISO/TS16949 automobile industry quality management standard certification for all production plants both in Japan and overseas; however, in September 2018, the international standard will be changed from ISO/TS16949 to IATF16949, which is more specifically intended for quality assurance in the automobile industry.
Ever seeking to increase quality, we have begun to apply the global QMS for the realization of global consistency in our products and services, because it is a priority issue in earning customer trust and ensuring satisfaction. In addition to this, we are also advancing efforts to acquire the new IATF16949 certification at all of our production plants, both within Japan and overseas.

We continue to improve this system in order to establish a globally standardized system that eliminates the occurrence of defects, while improving the QMS to enable it to be applied to new business fields.

Proper Manufacturing from the first step (Frontloading Activities)

Defects in products and services cause significant inconvenience to customers. Alpine conducts frontloading activities, which are quality assurance activities for the design, development, and manufacture of products, with the goal of following a policy of proper manufacturing in every process from the product planning stage. Specifically, we established a system of frontloading activities in the Quality Assurance Division to review product development processes from the perspective of quality, identify problems and institute measures. For products supplied to German automobile manufactures, we have implemented maturity level assurance (MLA) in accordance with the regulations specified by the Verband der Automobilindustrie e.V. (VDA: German Association of the Automotive Industry). We have developed a new memory function that records the history of operation in each product to ensure accurate analysis and early solution of problems.

Active Use of Quality Engineering (QE)

In order to meet the needs of our customers around the world, Alpine focuses on improving the robustness*of products to ensure that they perform as expected under conditions that exceed the limits of actual experience over a wide range of natural environments and road conditions.
Considering the importance of preventing quality issues, Alpine has adopted quality engineering (QE) concepts and methods for the comprehensive assessment of product function stability.

In the design and development stage, for example, we evaluate the stability of functions and optimize design parameters of both hardware and software while envisaging the manner and environment in which the product will be used.
In manufacturing, we apply QE concepts and methods to assess final product quality and optimize the processes to reduce variability in functional characteristics. We are also working to deepen our engineers' understanding of QE concepts and methods through in-house training programs, QE case study sessions, and QE reporting sessions. We continue working on the utilization of QE concepts and methods throughout our group to provide high-quality products that satisfy our customers.

*Robustness: The degree to which a supplied product can perform its intended function in any environment the customer might use it (hot/cold, humid/dry, dusty etc.)

Quality Evaluation Systems and Improved Product Quality through Close Attention to Customers

In order to provide customers with safe, high-quality products, Alpine is working globally to establish a quality guarantee system, as well as to improve overall product quality.
Through the acquisition of quality management system certifications such as ISO 9001 and ISO/TS 16949 at our plants worldwide, as well as through the establishments of quality centers in the US, Europe, China, and Japan, we are building a system that allows us to respond to our customers faster by being closer. Additionally, through the use of IT for DM (digital manufacturing) techniques in product development, as well as quality engineering in manufacturing processes, automation of production lines, and other changes, we are working to increase reliability and ensure high quality.

Through frontloading activities, we take part in the product development stage for products sold around the world.
My job is to draw up product certification plans during the early development stage, and to identify the aspects that involve quality-related risks, based on the information related to the products’ new functions and new technologies. I also organize the points to be evaluated, including data on defects that occurred in the past, as I work with the reliability evaluation staff to confirm the certainty of our products’ quality.
In the event that a problem is discovered in a product on the market, we work with the local quality center to quickly find a solution, then work with the Design Division to incorporate the countermeasures in the development of the next product, in order to prevent the problem from happening again.

Efforts toward Functional Safety for In-Vehicle Products

The need for safety in in-vehicle products increases as driver-assistance systems become more advanced and automatic driving systems are adopted, and Alpine has been one of the first to establish a productization process and system that comply with the ISO 26262 functional safety* standard for automobiles.
With the goal of developing human resources and an organization that can handle functional safety, in fiscal year 2017, we engaged in functional safety education for personnel in charge of engineering and production, and other activities to firmly establish the functional safety process at development and production sites.

Alpine Functional Safety Policy

“Alpine offers safe in-vehicle products that customers can use with peace of mind, through functional safety.”

* Functional safety: A concept of providing safety functions in order to reduce the hazard of harm to drivers, passengers, and others to a permissible level in the event of system failure.
