Last Planner Technique: A Case Study
Jesús M. de la Garza, Mun-Wei Leong · 2000
This paper presents the findings from the application of the Last Planner Technique to a project involving the construction of the Advanced Communication and Information Technology Center (ACITC) at the Virginia Tech campus. The scope of the case study was to measure the reliability of weekly work assignments. Data collected for a period of ten weeks was analyzed to produce five different Percent Plan Complete (PPC) ratios. These PPC ratios were used to compare the performance of weekly work assignments against weekly, monthly, and baseline schedules. Related information regarding the reasons for non-completion of work assignments was also collected. The paper concludes by recommending the use of weighting factors in the computation of the PPC ratios and the establishment of industry-wide benchmarks for PPC ratios.
