Abstract:
This empirical investigation has attempted to reveal the effect of six extrinsic
factors namely salary & benefits, working conditions, policies & procedures, relationship with
supervisors, coworkers, and subordinates on the individual job performance of engineering
staff at a leading, highest graded construction company in Sri Lanka. The study was conducted
as a longitudinal case study research with mix method where quantitative findings were further
validated by the insights from a qualitative study which highlighted the importance of
perception of such factors over the mere provision or presence of them. The study found a
positive correlation with higher predictability of variance of all six extra-individual factors
with job performance of engineering staff as possible causes for the decline of individual
performance. This could lead to a conclusion that extrinsic factors cause greater influence than
intrinsic factors over the performance of engineering staff at the concerned organization.
Findings were further reviewed using Herzberg’s Two Factor theory, performance equation
of Cerasoli, (2014) and MARS model of behavior.
