Singh Department of Mechanical Engineering National Institute of Technology, Raipur 492010 Chhattisgarh, India vikkiswarnakar@gmail.com; shailvdy@gmail.com; anil.kr.tiwari@gmail.com; amitrajsingh1@gmail.com Abstract In present scenario manufacturing organizations are facing problem-related to quality, cost, and customer satisfaction in the current market. To overcome such situation manufacturing companies are ready to adopt continues improvement (CI) techniques which keep them stable in fluctuation in demand as per the market situation. Lean Six Sigma (LSS) continues improvement methodology which helps to improve the bottom line result of the company with the use of their tools and techniques. The successful implementation of Lean Six Sigma approach provides significant improvement in key metrics but deficiency of proper implementation of LSS provides a negative effect. To prevent such situation need to have knowledge about their failure factors. The study main objective is to assess the Lean Six Sigma critical failure factors (CFFs) for implementing their framework in manufacturing organizations. The leading LSS-CFFs for manufacturing organizations situated in India has been identified and selected through literature review and experts opinion. The model on LSS critical failure factors has been developed using ISM-MICMAC approach. The developed structured model will help LSS practitioners, consultants, researchers to anticipate the potential CFFs to implement LSS framework in their organization for continues improvement and achieve a leading position in a competitive market. Keywords Lean Six Sigma, Continues Improvement, Critical Failure Factors, ISM-MICMAC, Manufacturing Organization 1. Introduction Manufacturing organizations is one of the rapid growing sectors in India and it has tremendous impacts in the Indian economy. India is 5 th largest manufacturer within the globe with total manufacturing value added of over 420 billion USD in 2016. The average of seven percent growth has been achieved every year which account 16 to 20 percent total GDP in India (The Hindu, Business Line, 2018). Today due to increase in demands for quality products and services, manufacturing organizations are continues adopting continues quality improvement approaches such as Total Quality Management (TQM), Lean manufacturing (LM), Six Sigma (SS). The Lean manufacturing approach is used to eliminate wastes, continuously improve quality, and create value to customers (Grasso, 2005; Fullerton et al. 2014; Swarnakar and Vinodh, 2016). Six Sigma is a methodology which highlighted the variation in the manufacturing process and helps to reduce them through their statistical tools and techniques (Vinodh and Swarnakar, 2015). The combination of these both approaches (Lean Six Sigma) provides extensive benefits to the organization and improves the bottom line result. The concept of combining LSS principles began in the middle the to late 1990s. The adaptation of the LSS approach maximizes the value of shareholder through continues improvement (George and George, 2003). Numerous studies have reported the LSS framework implementation benefits such as increase in production utilization rate, reduction in defects, improvement in quality, improve production capacity, improvement in key metrics, eliminate non value adding activities (Lee and Wei, 2010; Bhuiyan et al., 2006; Kumar et al., 2006; Vinodh et al., 2011; Vinodh et al., 2014; Chen and Lyu, 2009; Chakravorty and Shah, 2012; Waite, 2013, Swarnakar and Vinodh, 2016) The successful implementation of LSS framework in a manufacturing organization resulted in benefits such as uninterrupted and defect-free production. It also helps to achieve a higher degree of competitiveness in a competitive market if implemented successfully. The deficiency of proper implementation will achieve the negative effects which cause decrease quality, dissatisfied customers, 2161
