Abstract

The Critical Path Method (CPM), the Last Planner System (LPS) and location-based methods, such as the Line of Balance (LB), are discussed extensively in the technical literature about schedules. However, no discussion exists focusing on the differences and similarities of these methods in terms of their use in different countries. Using chi-squared and Fisher’s exact tests, this research compared three countries (Brazil, Finland, and United States) and the methods to evaluate both intra- and inter-country implementation to gain additional insights about their use. Results suggest statistically significant intra- and inter-country differences regarding how these methods are used, with a specific focus on mechanics in the countries, offering important information to address their various scheduling needs. The results reflect the current state of practice; engineering and construction managers should understand different ways of understanding scheduling. Such understanding can lead to more efficient communication with collaborators and when incorporating foreign teams in projects. The study identifies the need for further scientific explanation as to why these methods are used in the manner they are intra-country as well as adaptions made in inter-country relationships.
