INVESTIGATING THE RELATIONSHIP BETWEEN PLANNING RELIABILITY AND PROJECT PERFORMANCE: A CASE STUDY

摘要: Variability is an endemic problem in construction projects, which leads to the general deterioration of their performance. During last decade Last Planner System (LPS™) has been increasingly applied projects improve planning reliability as a strategy increase project LPS™ promotes series actions and methods reliability, monitoring Percentage Plan Completed (PPC) short term period. Nevertheless, there limited evidence studying properly relationship between In this paper, authors developed detailed research home building analyzing at activity level, order understand how changes levels impact over performance during phase. For doing so, two indexes are proposed: A index activity-based called Process Reliability Index (PRI), aggregated labour productivity project-based Project Productivity (PPI). At indicators compared with PRI. PPI PPC index. Statistical analyses for both were conducted showing positive robust trends when increased.
