Decision analysis using virtual first-run study of a viscous damping wall system

An A3 is a problem-solving tool, however, it can be used in other ways and the corresponding A3 formats vary depending on the purpose of use. For example, Toyota uses three basic types of A3 reports (Shook 2008, Sobek & Smalley 2008): problem solving proposal status. This A3 is a summary of our research on Virtual First-Run Studies (VRFSs), therefore its story line represents the flow and structure of a scientific paper. In creating this A3, the authors attempted to structure it so as to add the most value to Lean Construction Journal readers. Only the information and data judged to be the most essential are presented in a logical flow to help readers quickly capture the key contents and results of the research. For a detailed description of the research method used, the case study itself, and evidence to support the conclusions, readers may want to read the full paper by Nguyen et al. (2009) published in the Proceedings of the 17th IGLC Annual Conference. This A3 is submitted by way of experiment to the Lean Construction Journal and we look forward to receiving further comments and suggestions from researchers and practitioners on the value of reviewing research results in this format. We would like to thank contributors to the Project Production Systems Laboratory (P2 SL) at the University of California, Berkeley, USA, for providing guidance and financial support of this research. We are also grateful to CPMC, Sutter Health, and HerreroBoldt at the Cathedral Hill Hospital (CHH) project for their generosity in providing training and unlimited access to project data and personnel.
