Continuous Process Improvement


For a Globally Successful Company the Continuous Optimization of Processes and Products is of the Utmost Importance

The Rosenberger Group therefore uses the so-called Lean Six Sigma (LSS) method - a proven and results-oriented Quality Assurance concept. The goal of this approach is to achieve increased quality, reduce costs and ensure a total focus on customer satisfaction. Following this strategy Rosenberger employees are empowered to make operational tasks more effective and efficient.  

The LSS method combines statistical instruments for measuring, analyzing, improving and monitoring processes with lean management approaches. The latter focus on economic efficiency and are customer oriented. Extensive monitoring and reporting measures are put in place for ensuring optimal flexibility when responding to changing conditions. For this purpose interdisciplinary teams at Rosenberger make decisions based on statistical data analysis - as part of the company’s holistic approach to problem solving.

  • Quality improvements
  • Process and product optimization
  • Error management
  • Efficiency improvements
  • Productivity increases
  • Clear process rules and standards

The Phases of the DMAIC Project Cycle

The core process of the LSS approach makes existing processes measurable and optimizes them:


1. Define
  • Definition of optimizable projects
  • Presentation of the key figure development
2. Measure
  • Recording of the actual state
  • Determination of possible influencing factors
3. Analyse
  • Identification of relevant influencing factors
4. Improve
  • Development of new process steps
  • Implementation of new process steps
5. Control
  • Monitoring of implemented solutions
  • Securing sustainable optimizations

Further Process Optimization Approaches at Rosenberger:

This means of lean management stands for the organization of the workplace with the help of five simple steps: selection, systematization, cleanliness, standardization and self-discipline. The organized work environment leads to efficiency and effectiveness.

A targeted and systematic application of team tools and statistical methods ensures a Six Sigma process capability is already in place pre-series.

This method is used for optimal analysis and efficient redesign in the production area.

The shop floor management places production at the center of value creation. With the help of this approach production processes are optimized within the framework of cooperation between managers and employees.

These organizational as well as technical measures ensure the changeover of a machine in less than ten minutes (Single Minute Exchange of Die). Set-up refers to the time from the last good part of the old production lot to the first good part of the new production lot.
