It takes time and effort to report and explain big problem. In a large organization, people reporting big problem may easily get themselves involved in the departmental conflict and politics. Thus, no matter they want to play politics or not, people in major organizations tend to distort the seriousness of problems. Furthermore, the direct feeling of the problems will be totally lost when they are passed on by several levels. The situation will be even worse if the management style of the companies are authoritative and bureaucratic.
Complicated organization blocks communication.
The complication of organization structure is usually determined by the quality of staff and management as well as the task complexity. Lower quality management and staff means more need of expertise and functional staff who cannot be clearly defined in accountability and responsibility, thus narrower span of control and more complicated organization structure. Therefore, low staff quality affects not only the staff's individual performance but also the effectiveness of the whole organization. Most of these barriers are indeed the result of poor ethics rather than poor skills. The possible solution in this respect is cultivation of characters and management by example rather than acquisition of knowledge and skills.
