659 Background: In order to reduce long waiting times, a one-stop fast-track multidisciplinary outpatient clinic for gastrointestinal malignancies was initiated. Lean Six Sigma (LSS) is a combination of Lean-management and the Six Sigma methodology. LSS incorporates means to systematically identify and address suboptimal performance of a process. Lean and Six Sigma have their origin in the manufacturing industry, like the Toyota car factory, with largely homogenous products. In contrast, a complex high care oncology facility deals with heterogeneous patients. Our aim is to use the tools and strategies of LSS to increase the number of patients with an admission time (AT) of five days or less to ≥ 85% and to ensure that ≥ 90% of referring physicians receive the decisions formulated at the Multidisciplinary Team Meeting (MDTM) within one day. Methods: We have applied the DMAIC-cycle (Define, Measure, Analyse, Improve and Control) to our processes. The DMAIC-cycle is the management cycle of Lean Six Sigma. Results were measured before implementation of LSS and after for at least one month. Results: After implementing LSS causes for lags in AT, as well as for sending the documented decisions were identified. The lags in AT included patient delay, incomplete referral, official holidays and absences due to medical conferences. After the obstacles were successfully addressed we increased the percentage of patients with an AT ≤ 5 days from 48% to 70%, a 45% improvement. Causes for lags in sending the decisions, included verifying and signing the missive. Currently 99% of referring physicians receive the decision formulated by the MDT in ≤ 1 day. This is a substantial improvement from 2% to 99%. Conclusions: Lean Six Sigma is applicable in a multidisciplinary high care medical facility. Obstacles in the logistics of a complex medical facility can be identified and greatly improved.

Six Sigma Methodology

This paper presents a continuous improvement (CI) project based on the application of Lean Six Sigma (LSS) methodology. This project was carried out at coffee manufacturing industry located in northern area of Malaysia. The focus of this presented CI project is to improve the weight inconsistency problem of coffee powder packaging. The presented CI project was mainly guided with Six Sigma methodology of Define, Measure, Analyze, Improve and Control (DMAIC) steps, and related Lean tools applications. The step of Define summaries the overall view of CI project. In the step of Measure, current level of sigma based on defect per million of opportunities (DPMO) calculation was determined. Initially, 6% of rejected products were recorded, which it presents the sigma level at 3.1. In the step of Analyze, a series of team-based activities towards root cause identification was carried out. It included the applications of cause effect (CE) analysis and possible causes prioritization and close observations on packaging process. In the step of Improve, the related Lean tool was proposed to improve the problem under study. In the final step of Control, related supportive actions were suggested to sustain the effectiveness of the proposed solution. There are fourteen possible causes are initially identified in CE analysis and based on team’s evaluation process of possible causes prioritization four causes are collectively to be the most possible of root cause(s). Three close observation sessions were carried out to finalize the most possible root cause of the problem. Result strongly suggested that the high variation of coffee powder’s size and inconsistency is the root cause. An improvement strategy based on Lean Manufacturing approach called ‘poka yoke’ is proposed. The proposed improvement strategy was then validated based on real packaging process scenario. Result shows that the proposed improvement strategy is significantly effective to solve the problem with 0% of reject product was recorded so far, where it is not only produced the product within the acceptable weight of 215 and 208 grams, but also presents the reduction of weight fluctuation that close to ideal weight of 208 grams.

Critical Success

At the global level, the service industry represents a critical component for the economy and its growth trend is above of the other sectors. This sector alone is responsible for 63% of the gross domestic product and 45.5% of labor occupation worldwide. Despite its role in modern economies, the sector receives very little attention. In the literature, the authors have found the efforts that have been made to increase the efficiency and productivity of this type of organizations: adapting philosophies, tools, and/or techniques that were born to achieve this goal in the manufacturing industry, such as Lean manufacturing, total quality management, six sigma, lean six sigma, among others. The objective of this study is to perform an exhaustive literature review of the critical success factors reported in diverse studies of the implementation of these tools or philosophies in the service sector, as well as their differences, similarities, and results.

Six Sigma Methodology

This article seeks to discuss how project management can help the Lean Six Sigma methodology impact project outcomes. It is found that projects managers play a vital role in the successful implementation of the LSS tools and on meeting customer requirements. This article analyzes and identifies the factors and constraints that projects face with the implementation of Lean Six Sigma methodology within the project management perspective. Further, this study provides a comparative analysis of different studies based on LSS tools and analyzes their applicability in different industries. This study found that there is a strong need for project management concepts and tools in the LSS methodology and vice versa. The article also identifies specific concepts and tools of project management that can help to improve the likelihood of success of LSS projects and initiatives. This article discusses how these project specific concepts and tools can be effectively used in LSS environments.
