Integrated Theory of Constraints, Lean and Six Sigma Process Excellence
Methodologies: A Study in the Indian Manufacturing Sector
Abstract
This study is to explore the advantages and obstacles of implementing
Theory of Constraints (TOC), Lean and Six Sigma in Indian manufacturing
organizations. The research also elaborates on the challenges of
implementing TOC, Lean and Six Sigma in manufacturing organizations in
India, along with the changes in the culture that are required for
providing a proper climate to ensure success in a long-term manner. The
methodology used in this study is a descriptive study, which explores
and looks for the factors that influence the impulse or motivation to
implement TOC, Lean and Six Sigma in Indian manufacturing organizations
and factors that inhibit the implementation of TOC, Lean and Six Sigma.
To achieve this goal of integrated TOC, Lean and Six Sigma, a
significant review of the existing literature of the subject area has
been done to prepare a framework with the help of statistics in view of
the critical success factors. This research is a flow and arranged a
type of survey of organizations that is conducted using MS-Excel and
SPSS 25.0. The number of participants selected using a purposive
sampling method in this study was 227 TOC, Lean and Six Sigma experts
and owners or CEOs of manufacturing organizations in India. TOC, Lean
and Six Sigma be used for facilitating the improvement processes in
manufacturing operations, quality improvements and productivity. As some
obstacles exist in implementing the integrated TOC, Lean and Six Sigma
approach, the improvement processes and outcomes of change in the
culture are noteworthy and worthwhile. The implementation of TOC, Lean
and Six Sigma has also some constraints, including cost limitations,
skill limitations, limited facilities and other such limitations. The
implementation of TOC, Lean and Six Sigma during and after COVID-19
pandemic is not yet a matter of urgency or priority, and hence, cannot
yet be applied.
