Scheduling is a very crucial element in the management of projects, particularly the linear type of projects that follow a sequential pattern, such as highways, pipelines, and high-rise buildings. This paper compares two main scheduling techniques: the Critical Path Method (CPM) and the Line of Balance (LOB) technique. Despite the fact that CPM has been widely adopted in the construction industry for many years, LOB has particular advantages for projects with repetitive activities. This research investigates both methods' strengths, limitations, and situational applicability for linear project environments. This paper aims to assist project managers in determining which scheduling technique to adopt depending on the project characteristics, resources, and management goals and objectives based on the performance of the techniques in terms of certain parameters
