Physical resources and capabilities1. Changi AirportThe government and SIA had jointly invested in Changi Airport. It includes facilities such as a hangar, maintenance center and catering center, facilities that can be used by SIA, but also by customers of other airlines. So these services in Changi Airport are not exclusive to SIA. Airport service is valuable and important for SIA or other airlines. Unique and very valuable bass, so it's not a SCA.2. Aircraft: SIA holds 22% of the total production of 747-400 aircraft in the world. These planes offer longer flight range, better fuel efficiency and a quieter cabin than other airlines. It is unique and valuable that SIA has strong competitive power to attract consumers and lower costs than other airlines. Even if other airlines want to buy more 747-400s they will use large sums of money, which is difficult. Finance: There are two sources for financing SAI: revenue and shareholder funds. Both are valuable because they are key factors to support SIA's operations. Two factors that contribute to SAI revenue are overall cargo and passenger seat, and they are not unique because each airline must contain these sales. While SAI Group's shareholder funds were sufficient to pay for the majority of its aircraft purchases in the future and recent past, shareholder funds had been growing at a rate exceeding S$500 million annually, as well as no debt for the group, so this strong financial position is unique when compared to others. However, shareholder funds do not represent a sustainable competitive advantage, as the process of raising funds is not complex, all airlines have such funds and it is easy to silence. Human resourcesSIA has a complete human resources management system that provides for the training and motivation of its employees. employee. We can find the SCA of human resources from two aspects: labor cost, training. SIA's labor cost is the lowest among all major airlines, not only valuable but also unique at that time. The gap between SIA and other airlines is not easy to bridge in a short time. But if other airlines make great efforts to reduce human resource costs, they will eventually catch up with SIA because it is not too complex, specific and can be learned from accumulated experience. SIA is only one company that wins the National Training Award consecutively for three years. SIA has invested a lot of money in the employee training program, as it believes that man is the essential factor for the success of the company.
