Abstract
Every member has to decide on nonprogramed problems quickly, because the organizational environments are changing. In nonprogramed decision-making, he/she synthetically uses the grapevine (i.e. the rumor), in which value does not become defined, as well as formal information to make decision. The information quality in an organization is the usefulness of the information concerned in decision-making. In order for information to be useful to decision-making, information is shared by continuous communication before decision-making, and it is necessary to agree on the semantic interpretation of ambiguous information among members. However, communication may be divided or make a decision-making person fall into a surfeit of information conversely. Therefore, in this paper we paid attention to the organizational communication, and mentioned the method for improving information quality by continuous communication.
