Ball valve production – efficient und effective!
Our company objectives which, in accordance with the EFQM model (European Foundation for Quality Management) go right down to employee level, set the guidelines for our activities. Key figures allow us to objectively evaluate all improvements. Through BSC (Balance Score Card) and analysis of bottlenecks, all employees are working on the right things. LEAN methods and Six Sigma help us to make the right decisions so that we can work efficiently and effectively, even in difficult situations. Because we know that our customers set us high demands. Stable processes have the highest priority so that we can further strengthen our status as a reliable partner. IT-supported processes in planning and in modelling, help us to create and evaluate “best practice” solutions in order to transfer these or adapt them to other products or processes.
Ball valve quality – a key issue!
For this reason, we constantly use a wide range of different methods for improvement in order to continuously work on improving our competitive position. To achieve this, on the one hand we rely on our well trained staff and, on the other, on statistical methods which form the cornerstones of quality assurance. We have decided on the Six Sigma management approach since the quality improvement processes are carried out according to the DMAIC process and the real cause of a problem can also be found with complex problems. Further employees are trained in these methods on an annual basis so that we can be a strong partner at our customers´ side. For us, it is important to generate perceptible added value for our customers and thus further strengthen our exceptional position.
