Six Sigma: hints from practice to overcome difficulties

Quality management in heavy duty manufacturing industry: TQM vs. Six Sigma

“…In the current situation of high global competition and a climate of cost reductions, Six Sigma achieves significantly more on areas (Grima et al, 2013), "where some existing TQM efforts In addition, it is believed that Six Sigma has risen from the ashes of TQM and its shortages by introducing new concepts and approaches (Black and Revere, 2006); with literature suggesting that Six Sigma application of root-cause techniques discovers variability, and ensures a more thorough search than any other previous quality improvement. Perhaps due to Six Sigma being data-driven, using measurements to analyse problems and thereby improve the process or outcome, and enabling organisations to position their quality improvement effort in comparison to others (Grima et al, 2013); all of which can be compared to TQM, which has no way to measure quality (Black and Revere, 2006).…”

In summary, it is argued that Six Sigma projects are Despite an obvious lack of criticism against Six Sigma except some methodology difficulties and implementation issues (Grima et al, 2013), some academics claim that it is merely an addon project management tool (Nonthaleerak and Hendry, 2008), and a repacked version of TQM which has simply added and retracted a few components and been flogged under a different name (Bergquist et al, 2005). Additionally, some researchers question Six Sigma's originality, claiming that it has been around for many years in the form of problem solving, team building, and SPC, and that there is nothing new about it (Reed, 2000).…”

Six Sigma through Poka-Yoke: a navigation through literature arena

“…Although the belt-based training system is prescribed as yet another cornerstone of Six Sigma framework, many case studies reporting only the implementation of DMAIC to achieve the goals of Six Sigma (without the implementation of belt-based training infrastructure) have been reported in the literature arena [8,15,30,[32][33][34]. In fact, during the conduct of the literature survey being reported here, as many as 21 papers dealing only with the DMAIC framework of Six Sigma could be encountered.…”

Use of Six Sigma and Kaizen Methods to Reduce Concrete Iron Defects (Case Study of PT. Hanil Jaya Steel)

“…[5] As a result of the empirical work the authors proposed a new specific and individualizedframework for the public sector called: "Kaizen projects conceptual schemes (KPCS), based on thecycle Plan-Do-Check-Act in order to form a theoretical and practical guide that can serve as a base forlocal governments seeking to implement Kaizen in their management. [9] The welding process in pipeline construction takes around 65% in the pipeline replacement project schedule and critical path for the project. From two previous segment, contractor have a reject welding ratio 14% and reject material 7%, so it will be reduce into less than 5% and 3%.…”

“…These improvements align with BSC Frame; Learning and innovation, Internal Process, Customer, and Financial. [10] Pere Grima, et al Have grouped some of the most frequently into four main areas: implementation and organizational aspects, compliance with the DMAIC methodology, statistical tools and techniques and implementation of project improvements and closures (Six Sigma: practice to overcome difficulties (Six Sigma : instructions from exercises to overcome difficulties,Pere Grima, Lluís Marco-Almagro, Sandrine Santiago & Xavier Tort-Martorell [11].Result shown that lean six sigma and continuous improvement (Kaizen) have positive influence for solving the problem of defect product [9].…”
