Implementing lean manufacturing system: ISM approach
Abstract: Lean Manufacturing
System has emerged as an important area of research in Indian context. The
requirement of Lean Manufacturing has increased due to defects in products
(semi finished and finished) and subsequent increase in cost. In this context,
this study is an attempt to develop a structural model of the variables,
important to implement Lean Manufacturing System in Indian automobile industry.
Design/Methodology/Approach: Various variables of lean manufacturing
system implementation have been identified from literature review and experts’
opinions. Contextual relationship among these identified variables has been set
after carrying out brainstorming session. Further, classification of the
variables has been carried out based upon the driving power and dependence. In
addition to this, a structural model of variables to implement lean concept in
Indian automobile industry has also been developed using Interpretive
Structural Modeling (ISM) technique. Questionnaire based survey has also been
conducted to rank these variables.
Findings: Eighteen variables have been identified from the literature and
subsequent discussions with experts. Out of which, nine variables have been
identified as dependent and nine variables have been identified as driver. No variable
has been identified as linkage variable and autonomous variable. From the model
developed, ‘Relative cost benefits’ has been identified as top level dependent
variable and top management commitment as bottom level most independent
variable.
Research limitations/Implications: The model so developed is a
hypothetical model based upon experts’ opinions. The conclusions so drawn may
be further modified to apply in real situation.
Practical implication: Clear understanding of interactions among these variables
will help organizations to prioritize and manage these variables more
effectively and efficiently to draw advantage from lean manufacturing system
implementation.
Originality/value: Through this paper we contribute to identify the
variables to implement lean manufacturing system in Indian automobile industry
and prioritize them. The structured model developed will help to understand
interdependence of the variables of lean manufacturing system implementation.
