Processing Unstructured Organizational Transactions: Mail Handling in the U.S. Senate
研究美国参议院办公室如何处理选民关于立法问题的邮件，提出将交易处理系统视为组织信息系统，分析非结构化交易的设计与反馈机制，对管理信息系统设计有启示。
The conventional view of transaction processing, which has focused primarily on highly structured transactions, oversimplifies the information processing environment confronting most organizations. This exploratory field study investigates how U.S. Senate offices answer constituent mail on legislative issues. The study develops a model which views transaction processing systems (TPS) as an organizational information system. Using this model, the paper next develops the position that when TPS are viewed this way, the design and functioning of all TPS may be analyzed using the answers to three questions: (1) what transactions will be accepted by the organization for processing, (2) what rules will be used for processing transactions, and (3) how will feedback about these transactions be routed upward? Unlike most structured transactions, mail transactions are designed by the correspondent rather than the organization. As a result, the task of answering mail is characterized by low analyzability and high variety not found in most other routine transaction processing applications. Implications for the design of systems to support the processing of unstructured transactions in other contexts are discussed.
