Abstract:
Research Questions: 1) Does the use of Last Planner (LP) improve project performance? 2) Does Integrated Project Delivery (IPD) show different project performance? 3) Do IPD projects use LP?
Purpose: The first objective is to figure out the relationship between IPD, LP, and project performance.
Research Method: survey of ‘Lean’ projects known to adopt LP, including IPD projects, to determine the correlation between LP implementation and Project performance (cost reduction + time reduction); and a T test between IPD and non-IPD projects.
Findings: 1) There is significant correlation between the degree of implementation of LP and project performance; 2) IPD projects do not show significantly different performance from that of others not adopting IPD; and 3) IPD projects do not show significantly different implementation of LP from that of others but their implementation is near to significance
Limitations: Limitations in sample size and data quality reduce the credibility of generalizations.
Implications: This exploratory research revealed interesting and important relationships between project structures and practices on the one hand and project performance on the other.
Value for practitioners: The findings from this paper can be used by industry practitioners to design project delivery systems for better performance.
