ABSTRACT
Trust” is not only an important factor in establishing harmonious personal connections but also the key to whether the long-term relationship among organizations could be sustained. If trustful relationship cannot be built between two parties involved, then many other control mechanisms, such as contracts, should be relied on to make sure the easy going of transactions.
However, departments of the organizations are not completely self-contained; they quite need other departments within the same organization to offer necessary resources and aids timely, which is the so-called “interdependence among departments,” or “interdependence” for short. Consequently, specific department should engage in interaction with others within the same organization to make sure the expression of performance of the department.
The main research objects of this study are those stated on the membership roster of Lighting Appliances of Taiwan Electrical and Electronic Manufacturers' Association (TEEMA). There are 251 firms in total. Of the initial questionnaires mailed, 104 were returned. In the survey, 91 participants responded with usable questionnaires, resulting in a 36.25% response rate. Below are conclusions drawn out of this study：
1.Marketing department considers most that it is highly interdependent with production department (73.63%；67/91). This conclusion is consistent with the researches of Thompson (1967) and Porter (1985), who think these two departments are highly interdependent. Marketing department considers most that it has low interdependence with human resources department (52.75%；48/91). This conclusion is consistent with the researches of Thompson (1967) and Porter (1985), who think these two departments are lowly interdependent.
2.All absolute values of t-value of the LISREL ESTIMATES (MAXIMUM LIKELIHOOD) λX between indicator variables of interdependence, trust among departments and interdependence, trust among departments are greater than 1.96; it means that all estimating parameters have approached a significant level of 0.05. Therefore, indicator variables of interdependence, trust among departments all have significant representation for interdependence, trust among departments. It means that these indicator variables are all important reference indicators of interdependent, trust extent among departments. Adopting them can effectively represent interdependent, trust extent among departments.
3.Marketing and production (human resources) departments, in respect of interdependence, low and high interdependence have significant differences. It means that the level of interdependence will affect willingness of cooperation among departments; i.e., the higher the interdependent extent, the higher the willingness of cooperation among departments; in respect of trust, low and high trust have significant differences. It means level of trust extent will affect willingness of cooperation among departments; i.e., the higher the trust extent, the higher the willingness of cooperation.
4.ANOVA and post-comparisons both reveal that there exists an interaction between marketing and production (human resources) departments, which means that the willingness of cooperation between these two departments is affected by interdependence and trust; i.e., when there exists a high interdependent relationship, the willingness of cooperation among departments will not be affected by the level of trust extent; but, when there is low interdependence, trust will play an important role. It may be the reason that low trust decreases willingness of cooperation among departments or high trust increases willingness of cooperation among departments.
