STAFF COMPETENCY ISSUES IN LINEAR SCHEDULING APPLICATIONS

Linear scheduling method (LSM) is a scheduling method that is based on achieving a continuous flow of resources as well as precedence requirements. Although LSMs have recognized strengths in dealing with resource-intensive projects that are composed of repetitive activities, LSMs are not used extensively. This study proposes a staff-technology fit model that aims to measure the extent to which the features provided by LSM match scheduling staff experience, know-how and capabilities. The aim is to understand why LSM is not used as extensively as expected in construction scheduling. A questionnaire survey was administered to professionals listed in the directory of the Construction Management Association of America (CMAA) to measure staffing-technology fit in LSM applications. Research findings indicate that LSM applications satisfy user requirements in construction scheduling by (1) providing information that is useful to project participants depending on their position and function in the project organizations, (2) presenting graphics that are easy to understand, and (3) providing ease in communication. Research findings also reveal that LSM is not only a scheduling tool but also a control tool. However, the findings also point out that (1) LSM schedules require much time and effort to produce, (2) there are only very few commercially available software programs capable of running LSM schedules, and (3) there are not enough training opportunities for project managers and their staff to learn how to use LSM.
