As world has witnessed that implementation of lean concepts in industries has resulted into enhanced productivity, better quality, higher profit, better customer satisfaction, sense of achievement in employees, better employee and employer relation, sense of belonging towards their work. In spite of these advantages lean philosophy has not caught the attention and imagination of top management in all kinds of industries for e.g. SMEs, service industries, system engineering and product development. The main reason of non-implementation of lean concepts can be attributed to various obstacles or barriers being faced by industries. Earlier research indicates that few of the barriers are known to the environment and attempts have also been made by researchers and experts in lean philosophy to establish a relationship between these barriers. In this paper the aim is the correct identification and confirmation of barriers of lean implementation in present scenario and establishing a relationship between them. It is also important to come out with the strategies to overcome the identified obstacles faced by industries in implementing lean philosophy. The approaches in this paper used are firstly in-depth knowledge of subject inanalysis by literature review, secondly by means of a comprehensive questionnaire circulated to various industries to collect the qualitative data, and lastly to validate the data and to derive the inferences. I. Introduction Lean manufacturing is a systematic way of finding all kinds of wastes (mudas) and then eliminating them by using lean principles and tools in order to improve the efficiency and effectiveness of an industry. Taiichi Ohno [1] invented this concept with the introduction of elimination of muda (waste) and introduced this concept in Toyota company and concept is also known as Toyota Production System(TPS).Lean manufacturing is based on three famous M’s [1] muda, mura and muri. These three terms are Japanese terms, muda means waste, mura means inconsistency and muri means unreasonableness. In lean manufacturing the main emphasis is on identification and elimination of all kinds of waste and waste can be attributed to all the activities which cost but do not add any value to the product. Seven types of identified mudas [1] which need to be eliminated are as under:- Over production.It means that items are being produced more than what is required keeping the demands into consideration. Waiting.Waiting for machine, material or any inputs come under the ambit of waste and results into loss of productive time. Unnecessary transport.Unnecessary movement of material, work-in-progress inventory and lack of transport results into loss of productivity. Excess inventory.Excess inventory will lead to losses and will not give the clear picture of reality in terms of supply chain management. Unnecessary motion.Any motion that does not add value is considered as unnecessary motion. Defects. If any defect occurs while manufacturing a product then repairs will cause additional cost. Over processing. If worker carries out operation more than what is required then it will be a waste of effort. A place for everything and everything in its place is the concept of 5 S and it entails the following:-  Seiri (sorting)  Seiton ( organise)  Seison (clean)  Seiketsu (standardization)  Shitsuke (discipline)  The five principles [2,3] of lean implementation which needs to be employed are as under:-  Define value as perceived by the customer.  Identification of value stream
