The Last Planner System (LPS) has been successfully implemented in both design and construction phases of projects, but there have been raised questions if LPS in design needs to be changed to better suit the nature of design, due to the inherent differences between design and construction. The Norwegian contractor Veidekke has developed a method based on LPS for use in design called Collaborative Design Management (CDM). This paper looks at how CDM works in practice by doing case study of two projects where the methodology has been employed. We found that the use of CDM led to better communication and cooperation within the design team and a better understating of and commitment to the project. There are also indications that the methodology should lead to a more efficient and controlled design process which in turn would benefit the following construction process. Although we have seen positive effects from the use of the methodology, we have also found it lacking in some areas. Specifically the lack of a formalized weekly work plan, approach for constraint analysis and PPC measurements.
