Evaluation of Baseline Schedule Metrics for Successful Project Schedule Performance

摘要

The development of a reasonable baseline schedule is a challenge for some construction professionals. Some construction projects experience schedule impacts or delays as a result of fatally flawed baseline schedules that produce an unreasonable forecasted completion. Accordingly, some organizations, public entities, private firms, software companies and consultants have developed checklists or guidelines for evaluating the mechanics of baseline schedules to improve the likelihood of forecasting a reasonable completion date. However, these guidelines have yet to be substantiated. The purpose of this paper is to identify and evaluate a list of industry-recognized metrics to determine whether a schedule is fatally flawed or suggests a reasonable forecast. Accordingly, this paper addresses the correlation between current Industry Metrics and developing a reasonable schedule. The findings are addressed after evaluating 27 current Industry Metrics against eight completed case projects within the commercial and university building sectors. The case projects are divided into two groups based on amount of delay. The analysis results show that between two groups there exist significant baseline schedule quality differences.
