Rationale Enhancing product quality is the most economically viable path and one of the crucial strategies to ensure the sustainable development of a business, especially in challenging economic times like today. The key to improving a company's competitiveness lies in finding ways to reduce costs to maintain the lowest possible product price while continuously striving for quality improvement to ensure that its goods and services achieve the highest quality. For large global corporations, to ensure increased production output, profit growth, waste reduction, and product quality assurance, manufacturers must focus on investing in quality assurance from the raw materials stage to the finished product. Additionally, ensuring the quality of Measurement and Testing Equipment (MTE) is essential for the automotive manufacturing sector, such as Bosch.
Through the learning process at the university as well as internships at Bosch's factories, the author understands the influence of MTE on production quality at production lines. Failure to control the long-term measurement and testing capacity of MTE can affect product quality and erode trust with customers. Recognizing the importance of controlling the measurement and testing capacity of MTE and wanting to gain a better understanding of the significance of quality, the author decided to choose the topic: ANALYSIS OF THE MEASUREMENT AND TESTING PROCESS CAPABILITY FOR INSPECTION, MEASUREMENT, AND TEST EQUIPMENT AT BOSCH VIETNAM CO. Objective Analyzing the current state of the MSA evaluation for MTE at Bosch Vietnam, and proposing solutions for implementing digitization in the management of SP elements and re-doing MSA inspection using Type 7 in Booklet 10 - internal documentation 3.
Scope and object Object: The measurement and testing equipment inspection and measurement process capability at QMM6 is achieved through the measurement system 1 Scope: - Scope of space: MTE falls under the management authority of the QMM6 Department within Bosch Vietnam Co. - Scope of time: Analyze the current operational situation for MTE management at the QMM6 department from 2022 to 2023 - Scope of content: Quality control for the MTE units managed by QMM6 and the application of digitization for SM control in inspecting the inspection machine.

About Bosch Corporation 1. History and development of Bosch The Bosch Group is one of the leading technology groups in the world with its headquarters in Gerling, Germany.
The group was founded in November 1886 by Robert Bosch with the foundation of the “Precision Machanics and Electrical Engineering Workshop”. In its early years, the Bosch Group achieved significant successes. Starting from as early as 1897, Bosch began manufacturing and developing electronic devices, clock ignition systems, and other industrial products. Robert Bosch consistently focused on quality and innovation, which propelled the company ahead of its competitive rivals.
By 1898, Bosch had conquered the international market by establishing its first business office on Store Street, London. The company continued to expand its operations to various countries worldwide. Bosch not only opens new production lines but also invests in research and technology development. This has resulted in the group maintaining a leading position in the industrial and technological sectors.
The 1950s and 1960s marked a period of strong growth for Bosch. During this time, the group has become one of the leading manufacturers of automotive technology and electronic systems, contributing significantly to the development of the global automotive and electronics industries. From 1960 to 1980, Bosch underwent significant transformations as it developed into a diversified corporation. Lambda sensors, which detect the amount of oxygen present at the exhaust gas output of catalytic converters, were first produced by Bosch, which also held the top spot in the automotive electronics industry.
In 1978, Bosch introduced the Anti-Lock Braking System (ABS), a technology that became a standard and allowed drivers to maintain control over their vehicles during emergency braking. In 1987, Bosch further introduced the Traction Control System (TCS), which prevented wheel spin on slippery surfaces during acceleration. With the Electronic Stability Program (ESP) system, Bosch reached a technological milestone in 1995. ESP prevents wheel skidding and has sold millions of ESP brake systems since its introduction.
Overview of Bosch Vietnam Company Limited Ho Chi Minh City became the home of Bosch's first representative office. With two branch offices in Hanoi and Da Nang as well as a powertrain factory in the province of Dong Nai that manufactures continuously variable transmission belts (CVTs) for automobiles, Bosch has increased its presence in Vietnam since 2007. Furthermore, Bosch maintains an R&D center in Ho Chi Minh City for enterprise solutions and technology, as well as one for automotive technology. In June 2022, the Center for Research and Development of Technology and Enterprise Solutions increased the scope of its activities in Hanoi.
