Vestas has designed a process for developing the most reliable and most tested turbines in the industry. It's a systematic approach we follow to design solutions that have the characteristics of Six Sigma, and live up to customer expectations. We call it the 'Vestas Product Development Process' and the four most important aspects of this are Identify, Design, Optimise, and Verify. At the start, we 'Identify' the exact needs of customers and stakeholders so that we can match the new design to these requirements with the optimum technical solution. Obviously, this plays an important part in the 'Design' stage. Here, we focus on the key measurable characteristics of a product or process. These are called 'Critical To Quality' measures - or CTQs for short. And, they include all the performance standards and specification limits that must be met. In considering functional requirements, we develop and evaluate alternative concepts. This enables us to select a 'best fit' concept, deploying CTQs and predicting sigma capability. Next, let's look at the 'Optimise' stage. This is where we refine the technical solution to ensure a robust design with a predictable performance. This involves the use of process capability information and a statistical approach to measuring tolerance both in the overall product, and in the detailed development of all components. In the next stage the designs are verified. At each step of the process, the design can be changed and refined to ensure the optimal certainty of the design's qualifications. This also involves going through every aspect of the supply chain to assess the suitability of the design for production, transportation, construction and maintenance. To summarise, our unique 'Vestas Product Development Process' is applied at all technical levels, from development of the overall product down to the detailed development of all components. This means it supports the verification and integration of components, as well as the overall verification of the turbine.
