In doing so, they aim to build a world-class economy. Their key priorities are to provide a range of high-quality services to: help new businesses get underway; support and develop existing businesses; help people gain the knowledge and skills they will need for tomorrow's jobs; and help Scottish businesses develop a strong presence in the global economy - building on Scotland's reputation as a great place to live, work and do business. As well as companies and individuals, they also work with universities, colleges, local authorities and other public sector bodies to achieve these goals.
