“BeaM!” is a production management system that aims at supporting a BIM-integrated application of Lean Construction Management methods on construction sites. In particular, an advanced variant of the Last Planner System is integrated with BIM information on data processing level. This paper transfers the theoretical concepts of the “BeaM!” production management system into functional requirements for software implementation. The functional requirements are introduced along with a set of use cases and actors. Furthermore, a first prototype built using these functional requirements is presented. The prototype has been demonstrated to and evaluated by a total of 20 domain experts from practice to evaluate the prototype and its underlying functional requirements. Following a Design Science Research approach, the evaluation is focused on practical utility and applicability of the prototype. Findings as obtained from the demonstrations and expert interviews are presented and future development directions are outlined in this paper.

“光束！” 是一个生产管理系统，旨在支持精益施工管理方法在建筑工地的 BIM 集成应用。特别是，Last Planner System 的高级变体在数据处理级别与 BIM 信息集成。本文转述了“BeaM!”的理论概念。生产管理系统转化为软件实现的功能需求。引入了功能需求以及一组用例和参与者。此外，还介绍了使用这些功能需求构建的第一个原型。该原型已经向总共20名来自实践的领域专家进行了演示和评估，以评估原型及其底层功能需求。遵循设计科学研究方法，评估的重点是原型的实际效用和适用性。本文介绍了从演示和专家访谈中获得的结果，并概述了未来的发展方向。
