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.

Big Picture

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).

Purpose The purpose of this paper is to examine England’s Accident and Emergency (A&E) arm of the National Health Service (NHS). It considers the positive impact that Lean has had and Six-Sigma can have in A&E departments to improve the quality and reliability of the service offered, in an area that is facing performance challenges. Design/methodology/approach Independent variables average monthly temperature data (degrees Celsius) obtained from the Met Office and weekly A&E data, patient volume is analysed alongside the dependent variable, the percentage of patients seen in 4 h or less. Findings The model produced a robust positive impact when Lean Six-Sigma is adopted, increasing the likelihood of A&E dependents meeting their performance objective to see and treat patients in 4 h or less. Research limitations/implications Further variables such as staffing levels, A&E admission type should be considered in future studies. Additionally, it would add further clarity to analyse hospitals and trusts individually, to gauge which are struggling. Practical implications Should the NHS further its understanding and adoption of Lean Six-Sigma, it is believed this could have significant improvements in productivity, patient care and cost reduction. Social implications Productivity improvements will allow the NHS to do more with an equal amount of funding, therefore improving capacity and patient care. Originality/value Through observing A&E and its ability to treat patients in a timely fashion it is clear the NHS is struggling to meet its performance objectives, the recommendation of Six-Sigma in A&E should improve the reliability and quality of care offered to patients.

Pengendalian kualitas dapat dilakukan dengan berbagai cara, diantaranya menggunakan metode Lean Six Sigma. Metode Lean Six Sigma dapat menunjukkan jalannya proses produksi sehingga diketahui pemborosan, kecacatan dan proses terjadinya produksi melalui value stream mapping. Lean Six Sigma dapat diterapkan di bidang industri, satu diantaranya adalah perusahaan CV. XYZ. Perusahaan tersebut memproduksi wajan dengan nomor 10, 11, 12, 13, 14, 15, 16, 18, 20, 22, 24, 26, 28 dan 30. Wajan nomor 18 adalah wajan yang paling diminati konsumen. Tahapan dalam Lean Six Sigma dimulai dari define, measure dan analyze. Jenis kecacatan diklasifikasikan menjadi empat kelas yaitu sangat serius (A), serius (B), cukup serius (C) dan tidak serius (D) dengan jumlah observasi sebanyak 78 hari. Kecacatan terbesar terjadi di kelas cacat sangat serius yaitu sebesar 44,38%. Level sigma merupakan kemungkinan besar kecacatan yang akan terjadi jika memproduksi satu juta produk. Pada penelitian ini, level sigma yang dihasilkan kecacatan sangat serius adalah 3,2, sehingga dengan menggunakan nilai Defect Per Million Oppertunities (DPMO) dapat disimpulkan bahwa dalam satu juta produksi kemungkinan produk cacat sebesar 44.211 buah. Berdasarkan analisis Failure Mode and Effect Analyze (FMEA), diketahui penyebab kecacatan sangat serius dikarenakan material dengan nilai Risk Priority Number (RPN) sebesar 84. Sehingga dengan menggunakan kriteria penilaian RPN diketahui bahwa kecacatan yang disebabkan oleh material tergolong sedang.  Kata Kunci: Demerit, Failure Mode and Effect Analyze.

ObjectiveThe COVID-19 pandemic emphasises the need to use healthcare resources efficient and effective to guarantee access to high-quality healthcare in an affordable manner. Surgical cancellations have a negative impact on these. We used the Lean Six Sigma (LSS) methodology to reduce cardiac surgical cancellations in a University Medical Center in the Netherlands, where approximately 20% of cardiac surgeries were being cancelled.MethodA multifunctional project team used the data-driven LSS process improvement methodology and followed the ‘DMAIC’ improvement cycle (Define, Measure, Analyse, Improve, Control). Through all DMAIC phases, real-world data from the hospital information system supported the team during biweekly problem-solving sessions. This quality improvement study used an ‘interrupted time series’ study design. Data were collected between January 2014 and December 2016, covering 20 months prior and 16 months after implementation. Outcomes were number of last-minute coronary artery bypass graft cancellations, number of repeated diagnostics, referral to treatment time and patient satisfaction. Statistical process control charts visualised the change and impact over time. Students two-sample t-test was used to test statistical significance. A p<0.05 was considered as statistically significant.ResultsLast-minute cancellations were reduced by 50% (p=0.010), repeated preoperative diagnostics (X-ray) declined by 67% (p=0.021), referral to treatment time reduced by 35% (p=0.000) and patient Net Promoter Score increased by 14% (p=0.005).ConclusionThis study shows that LSS is an effective quality improvement approach to help healthcare organisations to deliver more safe, timely, effective, efficient, equitable and patient-centred care. Crucial success factors were the use of a structured data-driven problem-solving approach, focus on patient value and process flow, leadership support and engagement of involved healthcare professionals through the entire care pathway. Ongoing monitoring of key performance indicators is helpful in engaging the organisation to maintain continuous process improvement and sustaining long-term impact.

ABSTRAKDinamika dan perkembangan ekonomi global dapat memberikan sinyal positif terhadap pentingnya peningkatan pemberdayaan dan daya saing produk di pasar. Dibutuhkan pemikiran untuk membangun keunggulan kompetitif, yang menjadi dasar bagi peningkatan produksi dan daya saing bisnis. Peningkatan produksi merupakan serangkaian aktifitas untuk membentuk produktifitas. Bila salah satu aktifitas produksi mengalami kegagalam maka akan berpengaruh pada kualitas dan kapasitas produksi. Kegagalan biasanya terindikasi dari waste/ pemborosan yang muncul di sepanjang value stream. Terdapat indikasi defect yang tinggi melebihi 10% di sortir dan packaging process. Permasalahan utama adalah adanya waste/ pemborosan yang mengakibatkan penurunan kualitas dan kapasitas produksi. Paper ini akan mengidentifikasi waste yang terjadi di proses produksi, mencari akar penyebab terjadinya waste, dan membangun alternatif solusi perbaikan.  Diperlukan pemikiran kreatif untuk dapat menaikkan efisiensi sumber daya dan daya saing bisnis di pasar. Metoda yang dipakai untuk menyelesaikan permasalahan adalah Lean six-sigma. Konsep ini menelusuri permasalahan inefisiensi dengan cara mencari nonvalue added activity dari munculnya waste di sepanjang value stream.  Kemunculan waste selanjutnya diidentifikasi lebih dalam dengan root cause analisys (RCA) dan failure mode and effects analysis (FMEA). Hasil akhir dari FMEA adalah risk priority number (RPN) yang menggambarkan prioritas atas mode resiko untuk dilakukan perbaikan. Dari hasil prioritas dirancang 3 alternatif perbaikan yaitu pelatihan operator, pembuatan SOP proses produksi, dan pelatihan karyawan quality control.   Dengan pendekatan net present value (NPV), maka diperoleh nilai NPV yang positif, artinya alternatif tersebut adalah layak untuk dijalankan. Alternatif ini meningkatkan nilai sigma dari sigma awal sebesar 2,80 menjadi 3,30. Kenaikan nilai sigma akan memberi indikasi adanya penurunan tingkat defect per million opportunities (DPMO), dan berakibat pada penurunan biaya sampai 20%.  Kata kunci: daya saing, keunggulan kompetitif, Lean Six Sigma, RCA, FMEA, DPMO
