Abstract

The Last Planner System (LPS) promotes collaboration to plan, prepare and execute work systematically. Make-Ready Planning (MRP) is a key LPS component, connecting mid- and short-term planning by proactively identifying and removing constraints. However, systematic deficiencies in MRP implementation have been observed, and MRP assessment mechanisms are limited to constraint management indexes and qualitative assessment of practices. Hence, finding easy to apply ways to quantitatively assess MRP collaboration and its impacts on LPS performance is identified as research opportunity. To address this, a Design Science Research approach was used to propose a methodology for evaluating MRP collaboration using Social Network Analysis (SNA) of objective LPS information captured by existing Information Technology (IT) support systems. This approach allows for the creation of a directional social network of interactions between constraint removal (source) and task execution (target) last planners. Assessing the average degree, centrality, heterogeneity, number of connected components and density allows to identify collaboration improvement opportunities as well as understanding the impact of collaboration on LPS performance, as the project progresses.
