To summarize the theoretical framework, the basic conceptual framework of logistics, supply
chain management and its cycles and the activities within them are discussed above. Lean
supply management is explored in detail explaining about lean waste and ways to prevent it
by lean tools & methods and its benefits. The lean system model developed by Shingo is
advancement/improvement in lean practice. Similarly green supply chain management is
explored in detail about explaining motives for GrSCM, its activities and the benefits.
Advanced green system model helps us to understand the green management system which
involves waste reduction techniques to give desired green business results. The perspectives
of lean and green supply chain paradigms are visualized and inferred about their interface,
implementation strategies drivers, barriers and benefits.
With the knowledge gained and with the scope to explore the case companies for relevant
information, questionnaire is prepared and the case companies’ results are projected in
chapter 4. Having described about supply chain, Lean, Green and their Integration, the way
that these have contribute for improving the supply chain are analyzed and discussed in the
chapter 5. Many important factors based on their influence over the supply chain are
considered for building the model which is discussed in chapter 6.
