SGER: High-Level Requirements

需求分析的失败越来越被视为系统设计中的一个关键问题。 由既定和稳定的组织工作流程模式产生的低层次要求相对容易理解，但较难确定由更广泛的工作流程体制和组织背景产生的高层次要求，这些背景决定了最终可以和不能用基于计算机的信息系统完成哪些工作。组织行动具有广泛自由度的环境，特别是当系统旨在改变组织行为时，设计师需要将搜索空间减少到可行的选项。 通过搜索空间定义和减少的战略来确定高层次需求的过程是使用Grossman、哈特和摩尔产权模型的增强版本来开发的，以在依赖于合同等非集成协调机制的复杂生产系统中创建任务责任和资产所有权的先验对齐模型。 这是用来确定一个有限的，但现实的工作流参数，框架的需求分析任务。 测试领域是先进的物流过程协调的信息系统支持的发展，但工作的结果将推广到更广泛的组织问题。http://www.ics.uci.edu/~king/hlr.html

Failure in requirements analysis is increasingly seen as a key problem in system design. Low-level requirements arising out of established and stable organizational workflow patterns are relatively easy to comprehend, but it is harder to determine high-level requirements arising from the broader institutional and organizational contexts of workflow that determine what ultimately can and cannot be accomplished with computer-based information systems. Environments with broad degrees of freedom for organizational action, especially when systems are intended to change organizational behavior present designers with the need to reduce the search space to viable options. The process for determining high-level requirements through a strategy of search-space definition and reduction is developed using an enhanced version of the Grossman, Hart and Moore property rights model to create an a priori alignment model of task responsibilities and asset ownership in a complex production system dependent on non-integrated coordination mechanisms such as contracts. This is used to determine a limited but realistic set of workflow parameters that frame the requirements analysis task. The test domain is the development of information system support for process coordination in advanced logistics, but the results of the work will be generalizable to a wider range of organizational problems. http://www.ics.uci.edu/~king/hlr.html
