This study attempted to investigate the process and barriers of flow of technical information in KWPA. A survey method was used to collect the data. Interviews with some key persons were also conducted. The target population included both experts and technical managers, and the information output of technical departments. Descriptive statistics and Spearman's rank correlation coefficient were applied to analyze the data. Results showed that overall production and use of technical information are relatively satisfactory, and the respondents generally used the technical. Lack of a holistic view of information management and systematic access to information were major drawbacks. The authors suggest applying a holistic view for information management to systematize the production and use of information and reduce the costs.
