Maximising the economic and social impact of Six Sigma

This paper reports on how Six Sigma training can be made more effective. The research is empirically based. To date it has engaged with over 100 respondents from 60 different organisations around the world. The questionnaire has been derived from leading refereed sources and expert practitioner experience and addresses both success factor and tools issues from three perspectives: (i) academic, (ii) training, and (iii) practice to help maximise economic and social impact of programmes. This topic is important because the popularity of Six Sigma adoption in organisations has grown dramatically over recent years. This is probably because many accounts of great cost savings and quality improvements have been published by major international companies. However, other companies striving to emulate this success are finding that effective implementation needs experienced and well trained individuals. To date, there have been few such surveys and this work-in-progress benchmarking study provides unique insight.

Acceptability of Lean Six Sigma in a developing economy:results from exploratory research in Nigerian consulting companies

The application of Lean Six Sigma (LSS) varies in different regions of the world in terms of both level of understanding and acceptability. Employing a qualitative methodological approach, this paper aims to explore factors hindering the acceptability of the LSS initiative in organizations and list factors required for successful application and implementation in a developing economy from the perspective of LSS consultants. Using Nigeria as a case study, primary data were collected though a number of semi-structured interviews with representatives of leading continuous improvement consultancy firms in Nigeria. Finding draws out links between major factors such as drivers and motivation, LSS performance, marketability and challenges to the acceptability and applicability of LSS in Nigeria. Further findings highlight major factors such as lack of management buy-in, level of awareness, certification driven market, Nigerian environment and culture, etc as problems that hinder successful implementation of LSS in Nigeria. This paper contributes to the theoretical foundation of critical success factors required for the implementation of Lean Six Sigma, with results from the experience of a developing economy.

Aplicación de la metodología Six Sigma para solucionar problemas de calidad en una empresa metalmecánica

En la actualidad muchas compañías enfocan sus esfuerzos en la chequera del cliente generando con esto una cortina de humo al interior de la empresa que hace que se descuiden los costos, se conviva con actividades que no agregan valor y se desconozcan las causas de los principales problemas de calidad que afectan al cliente. Este es el caso de la compañía metalmecánica objeto de esta investigación, la cual venía sobrellevando altos niveles de inventarios, reprocesos, problemas de calidad, falta de corresponsabilidad del personal, y otras situaciones que la estaban dejando vulnerable ante la competencia. Este fue el motivo que inspiró esta investigación en aras de validar una metodología de mejora continua para identificar, analizar, proponer, evaluar y reducir los costos de no calidad y sus implicaciones, de una forma ordenada, rigurosa y disciplinada. Posterior a la implementación del plan de acción los resultados no se hicieron esperar y la compañía mejoró su servicio al cliente sin incurrir en excesos de inventario, al igual que disminuyó sus sobrecostos de producción, los cuales eran generados en gran medida por problemas de calidad. Pero lo más significativo es que asimiló que esta metodología es un proceso continuo que no puede parar y que todo el personal de la empresa debe estar implicado.

Six Sigman soveltamisedellytysten ja -apuvälineiden luominen

Diplomityön tavoitteena oli luoda soveltamisedellytyksiä ja -apuvälineitä Six Sigma -parannusprojektien läpiviennille Perlos Oyj Connectorsin meistoprosessissa. Työn teoriaosassa käsitellään Six Sigman perusteoriaa, organisointia ja soveltamista sekä suorituskykymittariston ja tiedonkeruumenetelmien luomista. Kirjallisuuden tarjoaman teorian jälkeen työssä tutustuttiin meistoprosessiin ja Perloksen tapaan soveltaa Six Sigmaa prosessien parantamiseen. Tämän perusteella kehitettiin tiedonkeruu-, dokumentointi- ynnä muita apuvälineitä parantamisprojektien tueksi. Lopuksi koekäytettiin luotuja välineitä meistoon tehdyn osittaisen Six Sigma -projektin yhteydessä. Luotettavan tiedon saaminen prosesseista on perusedellytys Six Sigma -projektien läpiviennille. Menetelmän kouluttaminen työntekijöille on myös tärkeää. Erilaiset dokumentointi- ja laskentakaavakkeet toimivat projektien läpiviennin ja seurannan tukena. Työssä luotuja tiedonkeruu-, koulutus-, dokumentointi- ynnä muita apuvälineitä voidaan käyttää jatkossa apuna Perloksella tehtävissä Six Sigma -projekteissa. Mittaristoa ja tiedonkeruuta tulee kehittää edelleen, jotta prosessien toimintaa voidaan analysoida tehokkaasti. Työn lopussa on ajatuksia Six Sigman käytöstä sekä tiedonkeruujärjestelmien jatkokehityksestä.

Seis sigma : um estudo aplicado ao setor eletrônico

A influência da cultura organizacional na adoção de práticas de qualidade Seis Sigma: um estudo exploratório no segmento de farmácia de manipulação do Estado do Rio Grand do Norte

In recent debates about the issues of quality, the theme organizational culture and Six Sigma has appeared ever more frequently. In this context several authors suggest that the adoption of Six Sigma practices is influenced by culture. This work focuses on the relationship of organizational culture and quality to the practices of Six Sigma quality. Thus a descriptive-exploratory and correlational study of forty pharmacies of manipulation from Rio Grande do Norte was undertaken. Data collection identified features of companies and the level of use of the practices of Six Sigma quality that have been identified in the literature. For the Organizational Culture evaluation was used the Competitive Value Model (Cameron & Quinn, 1996), tested on north-American organizations and considered a high value academic and professional instrument. This model has been involved with the taximetrics created by Cameron who classifies quality culture in four levels. The results suggest that the Group and Developmental cultures are associated with higher levels of use of the practices of Six Sigma quality than the Rational and Hierarchical Cultures. Regarding the levels of the culture s quality, the highest levels were most frequently cited in Errors Prevention and Perpetual Improvement and Creativity, being the last one more positively related to the Six Sigma indicators

Aplicação da metodologia seis sigma em uma empresa de médio porte do setor têxtil

The Six Sigma methodology has received considerable attention in the last two decades. This is due to its great potencial to reduce processes variability, through the use of accurate data, facts and statistical techniques. The methodology seeks to improve the quality of products and services, maximizing the company s financial performance. Specifically, its implementation and results in medium-sized textile enterprises is unknow, although there are signs that the methodology can be applied with success. Considering this scenario, the goal of this research is to describe the application of the Six Sigma methodology in a médium-sized textile company specialized in the production of male shirts in the satate of Rio Grande do Norte, Brazil. First, we present a literature review, seeking to highlight the themes of quality, Six Sigma and its methodology for improvement. Then, we show the implementation of the project selected, depicting the steps and procedures that must be performed. The results confirm the efficiency of Six Sigma in providing significant gains to companies. It is observed substantial improvements in the speed of product development and the flexibility of the parts produced, reducing the process lead time from 12.5 to 6.2 days, which means a performance improvement of over 50%. This leads also to cultural and behaviour change, creating motivation for implementation of new projects and a continuous search for knowledge
