Worldwide package delivery company United Parcel Service (UPS) has three winners this year. All three - Cally Lau, Douglas Tse and Nancy Lee - said a professional knowledge of their market and a good understanding of customer needs were crucial to their victory. 'You must have professional knowledge, be up to date with market trends and have an understanding of customers,' said Ms Lau, a major account executive who has been with UPS since 1998. 'This helps to build up customer trust and encourages clients to stay with us.' Mr Tse, who has also been with UPS since 1998 and is a major account executive, agreed. 'It is important to provide the right result to satisfy customer needs. It is more complicated than just giving satisfaction to be successful,' he said. Ms Lee said 'excellence for knowledge' was her motto for success. 'We should know and understand what is happening because the customer may have problems, and we must suggest solutions for the problems to make them happy and satisfied,' said Ms Lee, who joined UPS in 2000 and is a major account executive. 'I am a bridge between the company and the clients.' UPS was founded in 1907 as a messenger company and has its headquarters in the United States. The company has evolved into a US$30 billion global corporation and its aim is to facilitate commerce. 'As the world's largest package delivery company and a leading global provider of specialised transport and logistics services, UPS continues to develop the frontiers of logistics, supply-chain management and e-commerce ... combining the flow of goods, information and funds,' it says.
