The construction industry in Germany has not succeeded in significantly improving productivity in recent decades, despite advances in prefabrication and automation. A lack of information exchange between project phases and participants leads to inefficien cies. Germany is heavily influenced by the HOAI, which follows a linear-sequential pro cess comparable to the waterfall model. This strict division into many project phases also leads to fragmentation of information, fostering a "silo mentality" and interface problems. For simple or repetitive projects, the waterfall-like project management approach may work well. However, given the complexity of construction projects and the increasing shortage of skilled workers, Germany is forced to develop alternative options for project execution. This thesis addresses the challenge of identifying suitable models of proceeding and project management approaches that can help overcome these issues. The current sta tus is examined and compared internationally. The goal is to gain insights in other coun tries and uncover best practices that can be implemented in the German construction industry. A systematic literature review forms the basis for identifying relevant models, which were further explored through expert interviews. Initially, the study addresses models of pro ceeding in general, before focusing on the construction industry. It was found that for complex construction projects with unpredictable conditions in a dynamic "VUCA" project world, predictive, also called traditional approach is not sufficient and adaptive ap proaches are needed. Relevant approaches identified include Lean Construction with the Last Planner System for the execution phase, Agile Design Management for the con ceptual phase and Integrated Project Delivery (IPD) to optimize collaboration and over come fragmentation of information. Due to limitations in time, the international comparison was reduced to one country. Hereby, the United States (US) were chosen as Lean Construction and IPD were devel oped there. Despite the limitations in finding experts in the US for an interview, the study provides valuable insights into the models of proceeding in both countries and their po tential applicability to the German construction industry. Based on the findings, a model was developed, that offers suggestions for using individual methods in the German con struction project process.      «
