Abstract

Benefits derived from the conduct of Big Room are well established. At present, the lean practitioners have been focusing on tapping the potential of this technique by systematizing the processes associated with implementation of Big Room. But there has been no quantifiable metrics to measure the same. In this context, this paper reports a study undertaken to develop and implement Big Room Effectiveness Index (BREI) that assesses effectiveness of Big Room. This research study adopted action research approach in the context of an Indian real estate developer. A core group within this developer was formed to steer the initiative of BREI. Based on literature review and interactions within core group, 10 measures for assessing effectiveness of Big Room were identified, which are grouped under four categories: collaboration, look-ahead planning, knowledge building and tools used, and continuous improvement. The framework was codified with some flexibility to provide inputs like parameter weightages and rating of these parameters. The developed BREI was implemented in an ongoing real estate project. The BREI was plotted on a monthly basis and it provided valuable input to participants involved in the Big Room meetings and suggested areas of improvements.
