<p> The purpose of this study is to identify the suppliers’ involvement in innovation and New Product Development (NPD) of wind turbine manufacturing. In this thesis we analysed the sources of innovation and also explored the benefits that the companies derive when they involve the suppliers in the process of innovation and NPD. We present results from the study of 31 wind turbine producers across the globe including, small, medium and large companies. The conclusions are that most of the companies claimed that they involve suppliers in innovation and NPD. In the theory chapter, we have presented different techniques of suppliers’ involvement in innovation: <strong><em>to</em></strong>, <strong><em>with</em></strong> and <strong><em>by</em></strong> (Wintelism) the suppliers. Most of the companies use ‘’<strong><em>to</em></strong>’’ the suppliers technique when they involve suppliers in innovation. Improved quality, lower cost and utilising the suppliers’ knowledge & expertise are the main benefits that companies receive when they involve suppliers in innovation and product development.</p>
