Thorough literature survey on lean manufacturing and lean assessment has been carried out in order to achieve
the objective of this research. The existing and current model of leanness is identified and studied. However, the
emphasis of the research is more on the identification of indicators, practices or tools or techniques for the
implementation of lean in manufacturing. Keywords such as “lean manufacturing”, “lean production”, “lean
assessment”, “lean measurement” and “lean indicators” have been used throughout the literature survey on various
databases such as Scopus, Google scholar, ISI Web of Knowledge and so on. The survey has finally resulted in a
total of 25 articles for this assessment purpose, which basically focuses more on the determinants and key areas for
leanness measurement in manufacturing. The aim of the study is to determine, through literature survey, the most
used or common indicator and the usefulness of the indicators in the manufacturing industry. Thus, the frequency of
each indicator which has been mentioned by previous scholars has been used as the basic analysis in order to design
the conceptual model
