“…Savings were claimed due to lowered usage of a variety of resources. Examples include less employee time (e.g., fewer materials handlers and elimination of weekend cycle counting (Mistry, 2005a, 2005b), less overtime (Billesbach, 1994), shorter process time via better tooling (Deb et al, 2010), fewer production workers (Billesbach, 1994; Conti, 1996), and fewer hours lost to safety incidents and associated lower insurance premiums (Karuppan et al, 1996)); lowered inventory levels and associated holding costs (e.g., Billesbach, 1994; Kaplinsky, 1994); less need for facility space (e.g., due to less inventory on factory floor or in stock rooms [Kaplinsky, 1994; Mistry, 2005a, 2005b]), reduced use of material and labor (e.g., by reducing scrap and rework (Carmignani, 2017; Hung et al, 2011; Murugaiah et al, 2010; Orbak, 2012; Thomas et al, 2009), use of less or cheaper materials (Deb et al, 2010; Krovvidi et al, 2019; Randhawa & Ahuja, 2018) or by more exact filling of packages (Baia, 2015), less use of water (Kaushik & Khanduja, 2009; Pinto Jr. & Mendes, 2017), less energy consumption (Pinto Jr. & Mendes, 2017; Thomas et al, 2009), and lower production costs by rebalancing workers on machines (Kovács, 2020; Sarkar et al, 2015).…”

Even a cursory reading of the literature on process improvement shows that there are many accounts proposing that operational as well as financial gains can be made using methodologies like JIT, TQM, Six Sigma, and Lean. While some studies have investigated the statistical links between process improvement practices and corporate financial outcomes in large populations of firms, documentations of how individual firms can determine economic value derived from their own process improvement projects are scarce. We reviewed the literature, first ad hoc then systematically, to investigate the extent to which studies have covered the determination of process improvements' economic value in manufacturing companies postimplementation, and how such assessments are conducted. The results suggest that retrospective value determinations at the plant level are exceedingly rare. In fact, only 0.09% of 35,968 scholarly articles produced on process improvement in the period 1980–2020 have that focus. Since expenditures on process improvement have alternative uses, organizations should have at their disposal benefit determination frameworks so that financially efficient decisions can be made. Building on literature reviews and additional sources, this study proposes a set of principles and a model for cost–benefit determination that make up such a framework in the context of process improvement.

The cold-rolled coil is a raw material for manufacturing industries such as automotive, household appliances, property, and other industries that use steel plates. The production process during January - June 2020 was not good enough, so that the production process had a defect. The types of defects include stoppage marks, bad trimmer, and over the pickle. This study aims to measure Cpk, and sigma quality levels' process capability and analyze the root causes of low product quality. This study uses the Six Sigma method with the phase Define, Measure, Analyze and Improve. The results showed that Cpk = 1.27, and the sigma value of 3.86. Types of defects that occur are a 72,9% stoppage mark, 17,8% bad trimmer, and 9.3% over the pickle. Recommendations for improvements can be made by conducting training for employees, supervising production employees, periodic maintenance of machines/equipment, and controlling production processes. Six Sigma implementation can identify and improve the quality problems that occur.

Six sigma has been used in different industries to reach operational excellence. However, in the chemical industry, the application of this methodology is limited. This research presents an implementation of the six sigma method for ammonium nitrate (AN) content optimization in condensate production for a fertilizer company in Colombia. The paper aims to determine the levels for input variables in the process, to meet desirable standards for condensate quality in terms of ammonium nitrate content. Based on the DMAIC steps implementation, it was possible to establish the main variables affecting the condensate quality and their optimal levels to reach an ammonium nitrate content below 15,000 ppm. These results demonstrate the impact that a six sigma project may have on operational effectiveness and quality improvement for meeting the customer requirements.
