Abstract

The Last Planner System (LPS) has been the focus of several studies in the Lean Construction community. Many papers have reported its implementation in different types of projects around the world, and more recently some quantitative studies attempting to evaluate its impact have been published. This paper aims to evaluate the impact of the LPS from a different perspective. Instead of using performance measures, this study is based on the perceptions of people involved in the implementation of the Last Planner System in construction sites. A survey was carried out with a sample of construction companies from the South of Brazil. In each company, interviews were undertaken with representatives from three managerial levels: site engineers, foremen and crew leaders. The results point out different perceptions for each of those levels. While most benefits perceived by engineers and foremen are concerned with the planning process itself, crew leaders have emphasize the indirect benefits of the system, such as reliability of material delivery and site organization. Moreover, understanding the perception of the main people involved with the implementation of LPS provides some indications of what is often misunderstood about this system, making it possible to identify improvement opportunities.
