"Quality doesn't happen by accident."

Robert Bosch

Our quality DNA

Since 1886, Robert Bosch has always placed the quality of his products as a fundamental value. Guaranteeing the satisfaction of our customers and compliance with their requirements on the products and services delivered remains our priority today.

Our 14 quality principles

Our 14 quality principles, resulting from 130 years of experience in the industrialization and manufacturing of our products, are executed on a daily basis by all of the Group’s 400,000 employees.

Stop sign

Customer requests are communicated within the factory and reviewed directly at the designed station. They are dealt with systematically and quickly with problem solving methods.

Andon rule

In the event of non-compliance or exceeding intervention limit in the value chain (Source, Make, Deliver), the employee must stop the process or inform hierarchy.


All directives and instructions for safety, environment, health and work are monitored. 5S standards are defined and respected.

Process parameters

All process parameters which influence product quality are clearly defined and systematically monitored according to the control plan. Confirmation of process ensures that the values and tolerances are respected for the defined process parameters. Deviations are systematically documented and removed in a sustainable manner.

Control measures

The process control plan defines the type and use of control and support means for each process. All means of control are calibrated and used only during their period of validity. Any suspicion of functional failure and damage should be reported.

Check the Checker

All tests / processes for detecting errors must themselves be regularly tested and approved. All inspection processes, including maintenance and adjustment processes, should be evaluated to prevent potential failures.

Total Productive Maintenance

For each station, a maintenance standard is defined and respected. The four-pillar TPM maintenance model, including self-maintenance and preventive maintenance, must be set up for each station. The roles and responsibilities of manufacturing and support services are clearly defined.

Tool life

Tools that have an impact on product quality are tracked and monitored. An alert system is set up to warn, planned or not, any tool replacement or maintenance needs. Each tool must be checked in relation to the peculiarities observed during assembly / disassembly. In the event of irregularities, precautionary measures must be introduced to ensure the quality of the products.


Every interruption of continuous production presents potential quality risks. This is why the definition of a standard is necessary. This standard must describe the management of components that are in the process of interruption. All equipment are evaluated regarding the quality risks associated with interruptions in accordance with a standard. After longer interruptions, the process must be validated again. Series change processes must be assessed by appropriate methods.


Components, products and containers are clearly identified throughout the value chain according to a defined standard, in particular via a strict color code. The products must be protected from environmental influences in accordance with the guidelines.

Alterations / Scraps

Scraps should be disposed of in accordance with a standard and unauthorized reuse of these parts should be avoided. If a touch-up is essential, it must be carried out on a validated installation and it is limited in time or quantity. A special authorization is as well needed. If the touch-up process is needed on a lasting basis, it should be integrated into a standard process.

Pieces fallen to the ground

"Parts that have fallen or cannot be affected must be discarded"; each employee must respect this principle, regardless of their assignment or hierarchical level.

Compliant product

During assembly or assembly processes, only the right product should be made available to the employee. All other states should be out of direct reach.

Residual quantities

Residual quantities must be clearly identified and stored in a safe manner. The FIFO principle must be respected. The maximum storage time must not be exceeded. When implementing a technical modification of the product, the residual quantities are taken into account.

Because quality is our priority, our site is certified by approved third-party organizations, allowing us to offer our customers services in accordance with standards in force.

Our quality laboratory

With an analysis laboratory offering many tools and skills, Bosch Mondeville uses all the best means to guarantee the quality of your products. Thanks to the samples taken on-line during production, our laboratory is a key element for the approval of parts.

Whether it is dimensional metrology, visual and material analyzes, thermal and mechanical tests or calibration, our quality laboratory has all the skills and resources necessary to ensure the quality of your products, regardless of the market in which it operates.

Dimensional metrology

  • Point-to-point contact measurements, continuous contact scanning, non-contact (optical)
  • Part or finished product approval
  •  Definition of measurement methods
  • Geometric characterization of tools
  • Geometric defect characterization (dimensional analysis)

Thermal tests and mechanical

  • Thermal shocks, VRT
  • Vibrations combined with temperature
  •  Thermal or climatic cycles
  • Healthy fog
  • Tension / compression test

Visual analysis, material

  • Metallographic cut
  • Optical microscopy with measurement
  •  Surface matter analysis


  • Multi-size calibration with issuance of calibration certificate / verification report
  • Definition of calibration procedure
  • Uncertainty calculation
  • Optimization of calibration intervals

Bosch Production System

The Bosch Production System is a set of principles integrated into our 4 manufacturing plants in order to adopt a lean organizational model. This model which is part of a logic continuous improvement, only releases added value and does not create waste. Recognized and proven, our production system differs from others in particular by its social dimension. Employees are placed at the heart of the system which makes it as unique as efficient.

Bosch système de production

Because we are aware that the success of a company does not only depend on the performance of a single service but on all of them, Bosch has created the Bosch Production System which manages processes holistically by considering the entire value stream. Coupled with a bottom-up approach, the BPS guarantees that all levels of the organization are involved.

In order to continually improve production flows, we have adopted the Shopfloor Management approach. Combined with high-performance 4.0 tools such as ActiveCockpit, this method allows us to manage the workshop as a whole and to follow a complete lean manufacturing approach.

Thanks to data mining, information circulates in real time and allows us to gain reactivity and agility.

Always with operational excellence as our main objective, we create stability in processes by standardizing the best of them.

Our results testify the efficiency of this production system with a service rate of 100% and a fault rate of less than 1 ppm in the automotive business.

8 BPS principles

The eight BPS principles form the basis of cooperation in design, sustainable removal waste and fulfillment of the agile ordering process.
