Survey of Motivations, Benefits, and Implementation Challenges of Last Planner System Users

The number of construction project managers initializing the use of the Last Planner System of Production Control (LPS), an operating system for project management designed to optimize work flow and promote rapid learning, is rapidly increasing, motivated by industry trends and testimonials of its perceived benefits. This study, limited to the building sector, is a systematic literature and testimonial search of the perceived motivations and benefits or challenges for choosing LPS. It substantiates the claims of those perceptions through a structured survey of senior and mid-level managers. Quantitative statistical tools infer that practitioners who use LPS experience more reliable planning, better supply chain integration, and less work flow time. However, managers who directly implement LPS are faced with external resistance from clients and subcontractors, and feel that their organization does not offer the necessary incentives for adopting LPS, indicating a possible clash of paradigms. The case studies and testimonials were available in the literature referenced in the paper, but the survey and the method for analysis are new and have not been published elsewhere, either wholly or in part.
