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.

了解信息相互依赖性的本质并为模块化信息系统开发项目开发控制组合


为了更好的治理，信息系统开发 (ISD) 项目通常根据客户需求进行事前分解，以创建独立的模块。遵循这种模块化方法可以独立、高效地构建 ISD 项目工作。然而，鉴于 ISD 工作的综合性质，维持 ISD 项目内不同模块之间的信息流至关重要。通过对六个 ISD 项目的深入研究，我们发现 ISD 项目模块之间存在四种类型的需求信息相互依赖关系。接下来，我们确定适当的控制组合来管理不同类型的模块间需求信息相互依赖性。结果表明，不同类型的需求信息相互依赖，需要通过不同的控制组合进行治理。我们的研究通过确定微妙的机制为 ISD 文献做出了贡献，通过这些机制，通过应用适当的控制组合可以更好地管理需求信息的相互依赖性。我们的研究还为 ISD 项目治理提供了重要的实际意义。
