Abstract:
The overall purpose of this research paper is to unearth current research gaps in relation to five variables i.e. quality of
work life, personality, organizational commitment, performance appraisal and job performance for future systematic
empirical investigations. Nine research gaps related to these variables have been identified through a desk research
study. The conceptual confusion is one of the research gaps and it relates to quality of work life as well as job
performance. Formulating working definitions for both constructs have the potential of minimizing the existing
confusion and disagreement. Different types of relationships among the variables were identified and consequently
those variables were labelled as independent, dependent, mediating and moderating variables. Finally a nomological
network providing associations among the five variables was developed. The literature survey, logical arguments and
general system theory provide a solid foundation for the developed frame work. Furthermore, the developed
nomological network was proposed to be tested empirically in the research setting of Station Masters of Railway
Department, Sri Lanka.
