In this paper, Lean Six Sigma tools and techniques were utilized to determine the root causes of waste in a water bottling process and proffer solutions to remove these sources of waste in order to produce only standard quality items with minimal to zero waste generated, and also to attain a reduction in production cost. The Value Stream Map (VSM) tool was used to highlight the sources of waste in the current state of operations at the plant, as well as to proffer an improved future state of the production processes at the plant. Also, the Define-Measure-Analyze-Improve-Control (DMAIC) framework of Lean Six Sigma methodology was employed to statistically analyze the root causes of waste in the plant. The analysis showed that the major sources of waste which constitute approximately 80 per cent of waste in the plant are water volume variation, alignment error in the shrink wrapping machine and manual inspection. After implementation of the proposed solutions, manufacturing lead time and cycle time are expected to reduce by approximately 42.1 per cent and 22.2 per cent respectively, with a reduction of 2 quality inspectors in the bottling process, leading to a drop in labour cost.

This work presents results of improvement in the productivity of Arthrospira platensis (spirulina) in a company dedicated to its production. The six sigma methodology was applied in production processes that require the use of bioreactors. Starting from the analysis of the current state, aspects, physical and chemical variables that directly influence the productivity achieved were identified. Various culture media were tested and subsequently scaled for industrial production. In addition, the incorporation of carbon into the culture medium was controlled, optimizing the range of potential hydrogen pH. The identified parameters were measured and six sigma methodology strategies were assigned. An improvement in productivity corresponding to 66% was verified with the same quality of final product. Keywords: Six sigma, Bioreactors, Productivity, Arthrospira platensis. References [1]E. Ariawan and A.

Six Sigma and Lean Manufacturing are the two most popular and successful programs espoused by the industries over the last few decades. Many companies such as Toyota, Danaher Corporation, General Electric, Motorola and many others have achieved impressive results by implementing either a Lean or Six Sigma methodology in their organisation. Six Sigma, originated in Motorola in mid 1980s, brought revolution in the industries worldwide and has become the long term business strategy to achieve competitive advantage and to excel in operations excellence. Six Sigma is widely recognized as a methodology that employs statistical and non-statistical tools and techniques to maximize an organization’s Return on Investment (ROI) through the elimination of defects in processes (Antony et al. 2011). Lean Manufacturing, on the other hand, was another quality initiative proposed by Americans in response to compete with Japanese manufacturers and its superior manufacturing techniques (following the concept of Toyota Production System (TPS) to resolve quality problems in their organization) as their import became serious concern to western producers.

The delivery process of any IT organization depends on the effective software development methodologies. Along with conventional software development methodologies, corporates are also found to adopt various quality standards in order to enhance their development methodologies. Although there were substantial researches work carried out in past, majority of the study discusses about the theoretical implementation of quality standards. Due to various intermittent impediments, e.g., requirement volatility, skill gap, schedule slippage, etc., the standard quality models are very often violated in real time environment leading to degradation in development methodologies. Hence, this manuscript discusses an integrated framework using Scrum, Lean Six Sigma, and Agile which has been formulated on the basis on existing flaws in software development methodologies and propose some of the potential features to enhance it.


Lately, value stream mapping (VSM) is integrated with tools and techniques that belong to other areas of knowledge such as risk management (RM). It is well known tool in showing the value, value stream and the flow which represents three of lean manufacturing (LM) principles. This integration, gives more benefit in covering two of VSM issues such as considering the variability and uncertainty of production processes. In this paper, a model named variable value stream mapping (V-VSM) that integrates the two was showed, explained and tested. The model helps to generate the VSM in a dynamic way with the identification of current and potential risks. These risks might happen in the future bringing a strong impact on not reaching the main objectives in the defined time and cost. The model has been tested by conducting a case study in food sector. A current state map was built using both models, traditional VSM and VVSM. The results showed the effect of variability and uncertainty on the total cycle time (CT) and lead time (LT) values, where the traditional VSM failed to show it by being a static tool. Comparing the results of both models show the differences in presenting the real state of manufacturing environment..

This paper purpose is to investigate the benefits of Lean Six Sigma to the Malaysian automotive industry. Lean is an approach that seeks to improve flow in the value stream and eliminate waste. It’s about doing things quickly. Six Sigma uses a powerful framework (DMAIC) and statistical tools to uncover root causes to understand and reduce variation. It’s about doing things right (defect free). As global competition continues to grow, the pressure to improve becomes more andmore intense. Thus, a combination of both Lean and Six Sigma is born. This method provides an over-arching improvement philosophy that incorporates powerful data-driven tools to solve problems and create rapid transformational improvement at lower cost. Thus, this paper also tries to examine how the Lean Six Sigma can contribute and brings a positive impact to the automotive industry in Malaysia.

CV Marga Jaya (Pabrik II) adalah perusahaan yang bergerak di bidang pembuatan paving/conblock secara masal. CV Marga Jaya (Pabrik II) selalu berusaha mengurangi pemborosan yang terjadi selama proses produksi paving/conblock. Pemborosan yang terjadi antari lain, adanya produksi berlebih, transportasi, waktu menunggu, dan cacat yang berlebih.  Lean Manufacaturing merupakan pendekatan yang bertujuan untuk merampingkan proses dengan mengurangi pemborosan yang terjadi selama proses produksi. Pendekatan konsep lean manufacturing dimulai dengan membuat big picture mapping, dilanjutkan dengan waste assessment model (WAM), diagram cause and effects, value stream analysis tools (VALSAT), usulan perbaikan waste yang terjadi, dan pembuatan descrete event simulation (DES). Hasil yang didapat bahwa waktu menunggu yang terjadi diperbaiki dengan menggunakan conveyor, produksi berlebih yang terjadi diperbaiki dengan melakukan perencanaan produksi, dan cacat berlebih yang terjadi diperbaiki dengan menggunakan 5W+1H dengan sebelumnya menggunakan konsep lean six sigma dan didapat nilai sigma sebesar 4,31 sigma. Simulasi proses menunjukkan dengan mengurangi pemborosan, kemampuan produksi naik 15,36% (penjemuran 30 hari) dan 147,20% (penjemuran 7 hari).
