Schedule nervousness in a manufacturing system: a case study

Schedule nervousness has received significant attention from the academics for almost three decades. However, the majority of published works on schedule nervousness have relied upon experimental results as a basis for making conclusions and there appears to be very little field-based evidence presented in the relevant literature. This paper presents a case study of schedule nervousness based on field observations in a shoe manufacturing company in Indonesia. A model to quantify nervousness is also presented. This study provides an insight that schedule nervousness is an important issue in practice and efforts to quantify nervousness, as well as to understand how it occurred, are necessary in order to reduce nervousness.
