Abstract
This paper is exploring the process protocol map in industrialized building systems. Several critical success factors were identified and classified in seven groups namely; just-in-time factors, total quality management factors, business process reengineering factors, concurrent engineering factors, last planner system factors, teamwork factors and value based management factors. Using the Delphi technique, factors were established first by experts of construction projects. Afterward, the groups of factors were confirmed by the construction industry experts using the questionnaires based on Fuzzy AHP techniques for factors comparison. Based on the results the lean construction critical success factors are concurrent engineering and just in time factors respectively, which are the most important critical success factors in lean construction projects according to the industrialized building system process protocol map.
