Abstract: | This study primarily aimed at investigating empirically the relationship between
Kaizen 5S (housekeeping), waste (Muda) elimination, PDCA analysis and
productivity improvements among manufacturing firms in Ethiopia using the
Structural Equation Model (SEM). The study targeted 30 export-oriented
manufacturing firms. However, in order to overcome the problem of common
method biases, the data were collected from multiple respondents in each firm. The
questionnaire was distributed to 313 respondents that were selected proportionally
from 30 industries. The data for the study were collected through a five-point Likert
type questionnaire. Kaizen implementation practice was examined through
housekeeping (5S), Work standardization (PDCA), and Waste (Muda) elimination,
and productivity through the cost of production, labor and capital utilization. The
Structural Equation Model (SEM) was employed to investigate the direct and
indirect relationship between the variables. The SEM direct effect result indicated
that the firm’s 5S implementation practice was directly related to the elimination of
the seven deadly wastes and continuously improved the manufacturing process
through solving problems in the best scientific way. Furthermore, the 5S, waste
elimination, and PDCA Analysis of Kaizen continuous improvement methodologies
were perceived as methods for adding to productivity and efficiency in the
production process. Moreover, the SEM bootstrapping result indicated the fact that
PDCA analysis partially mediated the causal relationship between kaizen 5S
(housekeeping) and productivity. |
