Understanding the nature of information interdependencies and developing control portfolios for modularized information systems development projects
通过深入分析六个信息系统开发项目，发现了四种跨模块的需求信息相互依赖类型，并针对每种类型提出了相应的控制组合，帮助项目经理更好地治理模块化项目。
For better governance, information systems development (ISD) projects are often decomposed ex ante, using client requirements, to create self-contained modules. Following such a modular approach allows independent and efficient structuring of ISD project work. However, given the integrated nature of ISD work, maintaining information flows across the different modules within ISD projects is essential. Through an in-depth examination of six ISD projects, we discover four types of requirements information interdependencies across ISD project modules. Next, we identify appropriate control portfolios for governing the different types of inter-modular requirements information interdependencies. Results indicate that different types of requirements information interdependencies necessitate governance through varying control portfolios. Our study contributes to the ISD literature by identifying the nuanced mechanisms through which requirements information interdependencies could be better governed by applying appropriate control portfolios. Our study also offers significant practical implications for ISD project governance.
