Continuous improvement (CI) systems still have room for improvement due to the difficulty in sustaining the system and attaining a high level of employee participation. This study looks to analyse the level of implementation in manufacturing companies of 16 CI routines, and how these routines foster CI and employee participation. Based on a general survey of CI managers from Spain which yielded 147 valid responses, a Cluster Analysis (CA) and a Factorial Analysis were performed in order to group both responses and the variables used into more comprehensive categories. Statistical tests were run to test for significant relationships. This paper introduces a new perspective on the issue of CI maturity levels by using CA to group companies into three categories based on the score of a set of 16 CI enablers, which were in turn reduced to four factors using Factor Analysis, allowing for the identification of improvement challenges depending on the maturity stage of each company. Three different maturity groups of companies were identified, named as Leaders, Followers and Laggards. Results show that companies with better scores on these factors believe to have more sustainable CI systems and a higher level of employee participation.

Purpose Environmental management (EM) is becoming increasingly important in all types of organizations. The food industry represents the top industrial sector of the Spanish economy; however, there is still little knowledge about how it is managed environmentally. The purpose of this paper is to present a descriptive analysis of the Spanish food sector. Design/methodology/approach This study undertook a descriptive analysis based on probabilistic sampling surveys from food companies in Spain. The survey was sent out to 900 companies obtaining 128 answers. Findings The results of this study show that companies with an EM standard tend to have a more developed system and a greater presence of EM tools and actions. Moreover, statistical differences were identified among the characteristics of companies and various factors that affect the evolution of their EM. Originality/value There are no studies that reveal a clear picture of the status of EM in the Spanish food industry. This study presents a clear starting point that might help policy makers, consultants, researchers and other parties to set new improvement routes so companies do not get stuck in their progress toward environmental excellence

Manufacturers have become progressively more aware of their operations' impacts on the triple bottom line (social, environmental and financial), and they are under increased pressure to account for their resource consumption and environmental footprint. These challenges are forcing companies to implement and combine different management approaches, such as ¿green¿ and ¿lean¿, to meet the needs of the ever-changing market demand. Using semi-structured interviews in 58 different companies, this paper shows how manufacturing companies carry out manufacturing and environmental practices. This study contributes to the current debate in the literature on environmentally friendly manufacturing by arguing that companies with advanced manufacturing practices do not engage in proactive participation in environmental management with tactical and strategic practices inside their organizations. Following that, some considerations for correctly measuring the environmental efficiency in companies are presented. The findings and recommendations of this study can be used to fully utilize the potential of environmental practices to simultaneously improve manufacturing productivity and environmental performance and to identify trends in organizational development.

Continuous improvement (CI) is still one of the strongest ways for companies to achieve process excellence in order to survive in nowadays¿ competitive environments. Yet, it is still very difficult to implement and sustain CI systems, mainly because of the difficulty in engaging people in these activities. Based on an exhaustive literature review, followed by a three-round Delphi study with Spanish experts, this paper helps to assess what the main elements are with respect to the CI system that could motivate employees¿ intention to participate in CI activities. Main results show 44 elements grouped into 10 factors that could affect employees¿ intention to participate. These factors were structured into a more comprehensive model following an interpretive structural modelling approach.

Purpose - Despite significant amounts of environmental management tools that are available for companies to use, no model guides them toward environmental excellence. As a consequence, the purpose of this paper is to develop an environmental management maturity (EMM) model that helps companies that are on the path toward environmental excellence. Design/methodology/approach - An iterative process was used to develop this model, starting with some semi-structured interviews with 19 companies within the Basque Country and two workshops with environmental experts. Following these steps, the initial version of the model was developed. Data from subsequent surveys carried out in Spanish and Italian companies, and a survey and semi-structured interviews in companies in the UK were incorporated into the model, yielding the final, more robust version of the EMM model. Findings - The EMM model proposes six maturity stages: legal requirements, responsibility assignment and training, systematization, ECO2, eco-innovative products and services, and leading green company. Each stage details a series of elements: description, agents involved, policies, tools, indicators, structure, and behavior over time graphs. This research confirms that a company's environmental management evolves through several distinctive stages, regardless of the industrial sector. Originality/value - The proposed model concludes that the defined maturity stages provide valuable guidance for industrial firms as it helps them identify their maturity stage as well as the steps they should follow to move to the next stage.

Environmental management has become a fundamental concern for organizations, customers, and citizens, yet there are few environmental management metrics that guide toward environmental excellence. This research presents a detailed qualitative model of the evolution of environmental management of a firm through the definition of maturity stages and causal influences. The model provides a technique for assessing maturity stages as well as steps that can assist or negate their ecological advancement. The causal-based classification helps companies to understand the need for nontechnical elements in the process, such as top management commitment. This article also contributes to the literature on integrative multimethod research, as it brings together several approaches to environmental management.

Implementing continuous improvement (CI) systems is one of the most effective ways to increase operational excellence. One pillar that determines the success of a CI strategy is a climate of commitment and participation among workers. Recent work has focused on identifying organisational factors that directly influence worker participation. However, when analysing these elements, the importance that middle managers have when creating a work environment that enhances employee involvement stands out. The aim of this paper is to identify specific middle manager trustworthy behaviours that impact the level of commitment and participation in a group of line workers in a specific CI environment. To accomplish this, we present a list of specific behaviours based on a concept mapping conducted among a representative group of industrial supervisors and operators in the north of Spain. These identified behaviours define managerial practices that could directly enhance the level of worker commitment and participation.

This study focuses on how innovation capability can be developed within a company and how information capability is integrated into the innovation process. Innovation, helped by elements that generate and share knowledge, is generated through different practices. Thus, the present study develops an analysis of the role of information capability in innovation through the assessment of the direct experiences of managers from innovative companies located in Spain through grounded theory methodology. Our findings suggest that strategy promotes the appropriate culture and values that are aligned with innovation in the company. Strategy also establishes and acquires the resources, both internal and external, that an organization needs in order to achieve competiveness through innovation. Moreover, the organizational culture and resources support the information capability, and this information capability in turn supports the knowledge management which supports and develops innovation. The contribution of this research is the proposal of a framework that explains the elements that underlie innovation management in companies. The paper contributes to a deeper understanding of how to use information capability and knowledge management as potential sources of innovation.

El trabajo en equipo es una de las competencias clave para el desarrollo de muchos profesionales, más si cabe, para el de los futuros ingenieros. Es por ello que dicha competencia se debe definir primeramente en los planes de estudios de estas titulaciones como posteriormente debe controlarse y asegurarse la adquisición de la misma por parte de los alumnos. El artículo que aquí se presenta propone un modelo que sirve de referencia para entender los factores y procesos que surgen del desarrollo del trabajo en equipo y lo completa con la definición de unas herramientas que sirve para evaluar el grado de consecución de la competencia por parte de los alumnos a lo largo de un grado en ingeniería industrial. El modelo se ha probado en base a datos experimentales realizados en una escuela de ingenieros española, aunque está diseñado para que pueda adaptarse a cualquier nivel educativo en el que el trabajo en equipo sea definido como una competencia a desarrollar en el alumno.

Purpose The purpose of this paper is to describe a readiness programme designed to increase employees¿ awareness of order and cleanliness as a way of building the necessary foundation for implementing and sustaining continuous improvement processes. In this paper, the authors propose a new readiness programme based on the principles of 5S, with the aim of strengthening employees¿ motivation and involvement prior to 5S being implemented. Design/methodology/approach The research is based on case study methodology, followed by a programme of four structured activities. The validity of the programme is shown through the implementation of the activities in two different organizations. Findings The readiness programme was applied before 5S was successfully implemented. The degree of awareness and motivation of the programme participants improved as a result of these activities. Moreover, the activities increased people¿s motivation to participate in improvement activities. Originality/value Applying a readiness programme before implementing 5S can help organizations to achieve and sustain improvement activities, thus increasing worker commitment and motivation.

Purpose: Achieving employee participation in continuous improvement (CI) systems is considered as one of the success factors for the sustainability of those systems. Yet, it is also very difficult to obtain because of the interaction of many critical factors that affect employee participation. Therefore, finding ways of measuring all these critical factors can help practitioners manage the employee participation process accordingly. Design/methodology/approach: Based upon the existing literature, this paper presents a 4-Phase (9 steps) diagnostic tool to measure the main determinants associated with the implementation of CI systems affecting employee participation in improvement activities. Findings: The tool showed its usefulness to detect the main weaknesses and improvement opportunities for improving employee participation in CI through the application in two different cases. Practical implications: This diagnostic tool could be particularly interesting for companies adopting CI and other excellence frameworks, which usually include a pillar related to people development inside the organization, but do not include tools to diagnose the state of this pillar. Originality/value: This diagnostic tool presents a user's perspective approach, ensuring that the weaknesses and improvement opportunities detected during the diagnose come directly from the users of the CI system, which in this case are the employees themselves. Given that the final objective is to identify reasons and problems hindering employee participation, adopting this user's perspective approach seem more relevant than adopting other more traditional approaches, based on gathering information from the CI system itself or from the CI managers.

Las empresas de hoy en día se encuentran inmersas en una feroz competencia por sobrevivir y sobresalir. Para ello, la clave de la excelencia está en desarrollar estrategias globales orientadas hacia la mejora continua de los procesos en la organización. No obstante, uno de los principales obstáculos a superar en ese camino hacia la excelencia es precisamente lograr la participación y compromiso de todos los trabajadores de manera sostenida en el tiempo. Este problema aparece citado en repetidas ocasiones en la literatura, pero las razones por las cuales las personas deciden o no participar de estas iniciativas siguen sin estar del todo claras. Este artículo busca aportar en el conocimiento de la relación entre los sistemas de mejora continua y la intención de participar de los trabajadores. Mediante una encuesta a empresas españolas, se detectó que aquellas empresas que puntúan alto en una serie de hábitos relacionados con el éxito de los sistemas de mejora continua, consideran que sus sistemas son más sostenibles en el tiempo y que sus trabajadores están más comprometidos. A la luz de estos resultados, se desarrolló un Panel Delphi para profundizar acerca de cuáles son los elementos claves que los gerentes deben de tener en cuenta a la hora de desplegar los sistemas de mejora continua, con el objetivo de fomentar la participación de todos los trabajadores, obteniéndose como resultado una lista de elementos claves.

This research focuses on the evolution of environmental management within firms. It is based on a survey and semi-structured interviews conducted among UK companies. Building on an evolutionary conceptual model, consisting of several maturity stages, we identify milestones', i.e. common practices companies engage in when progressing through specific maturity stages. Whilst clear commonalities can be identified, most notably linked to the order of maturity stages they progressed through and the emergence of commonly acknowledged practices linked to the individual maturity stages, the results also reveal a number of within-sample patterns regarding the companies' progression through the different maturity stages. It can be concluded that the maturity stages and practices identified in this research can provide valuable guidance for firms aiming to make progress in environmental matters, as they help them to identify in which maturity stage they are and sets out steps that they can take to move forward.

An extensive literature review was carried out to detect why design of experiments (DoE) is not widely used among engineers in Europe. Once 16 main barriers were identified, a survey was carried out to obtain first-hand information about the significance of each. We obtained 101 responses from academics, consultants and practitioners interested in DoE. A statistical analysis of the survey is introduced, including: (a) a ranking of the barriers, (b) grouping of barriers using factorial analysis, (c) differences between characteristics of respondents. This exploratory analysis showed that the main barriers that hinder the widespread use of DoE are low managerial commitment and engineers¿ general weakness in statistics. Once the barriers were classified, the most important resultant group was that related to business barriers.

The 5S methodology is a very appropriate way to initiate and achieve the process of continuous improvement. This paper studies management practices in successful Japanese companies in order to determine what 5S principles are behind them. After visiting and conducting interviews at five different plants, a multi-case study analysis was developed to identify the key aspects of the success of the implementation of 5S in Japan. Although each of the companies studied is different, there are commonalities that provide for interesting learning. As a result, best managerial practices based on 5S principles are explained, and the most important principles associated with the success of the 5S method are described and discussed.

El objetivo de este estudio es analizar si la gestión y el uso de la información es eficiente en empresas comprometidas con la gestión de la calidad y si depende del sistema de gestión de calidad adoptado por la organización. A partir de una revisión bibliográfica hemos establecido un conjunto de buenas prácticas que conducen a la gestión y el uso eficiente de la información en la organización. A continuación, usando un cuestionario, hemos recogido la percepción de los directivos sobre el nivel de adopción de las prácticas establecidas. Los directivos pertenecían a dos tipos de organizaciones: empresas que han adoptado la ISO9000 como sistema de gestión de calidad y empresas que han adoptado el modelo EFQM de calidad total. El estudio contribuye a lograr un conocimiento más profundo de la gestión y uso eficiente de la información como fuente de ventaja competitiva para la organización. El nivel de adopción de las prácticas que conducen a la gestión y uso eficiente de la información es elevado en las organizaciones comprometidas con la gestión de la calidad. Además se han detectado diferencias que dependen del sistema de calidad adoptado por la misma. Los datos se han obtenido de muestras pequeñas de empresas de diferentes regiones del mundo. Por otro lado, sólo se han tenido en cuenta dos sistemas de calidad

One of the most important enablers of continuous improvement sustainability is ease of communication, and doing so in a way that can be understood by all employees and allows information to flow rapidly throughout the company. Visual Management (VM) provides significant benefits in communication and standardisation which boosts the effectiveness of improvement systems. This article presents an in-depth literature review about the concept of VM and its benefits, and provides results from an exploratory study carried out in the Basque Country that aims to ascertain the usage of VM in 52 companies. Based on a literature review, 20 different VM elements were identified for improving the workplace. The implementation of these elements was studied, as was the relationship of VM with employee participation systems. The results of this study show a general moderate implementation of VM tools in companies with implementation levels differing according to company size. Some of the lowest scores are detected in the areas of visual control of quality, the displaying of indicators and process visibility. Moreover, statistical differences were identified between the implementation of suggestion systems and improvement teams and the implementation level of VM tools.

Explore the development of the information capability in companies committed to quality management and explore whether the development of information capability depends on the quality management system adopted by the company. The efficient use and management of information can be considered a capability for a company. From a review of the literature we first define information capability related practices. Then, through a questionnaire, we captured the perception of managers in two types of companies regarding the existence of information practices. We contacted companies that used ISO 9000 as their quality management system and companies that were committed to the EFQM excellence model. The paper contributes to a deeper understanding of the information capability construct. According to the results, companies committed to quality management have developed the information capability. Also, this study shows the differences in its development in terms of the quality system adopted by the company.The data has been obtained from small samples of companies from different regions in the world. Also other quality management systems could be considered.

Experimenters should be aware of the possibility that some of their observations may be unavailable for analysis. This article considers different criteria to assess the impact that missing data can have when running three-level designs to estimate a full second-order polynomial model. Designs for three to seven factors were studied and included BoxBehnken designs, face-centered composite designs, and designs due to Morris, Mee, BlockMee, DraperLin, Hoke, Katasaounis, and Notz. These designs were studied under two existing robustness criteria: (i) the maximum number of runs that can be missing and still allow the remaining runs to estimate a given model; and (ii) the loss of D-efficiency in the remaining design compared with the original design. The robustness of three-level designs was studied using a third, new criterion: the maximum number of observations that can be missing from a design and still allow the estimation of the given model with a high probability. This criterion represents a useful generalization of the first criterion, which determines the maximum number of runs that make the probability of estimating the model equal to one. The new criterion provides a better assessment of the robustness of each design than previous criteria.

Teamwork is one of the most powerful tools to ensure success across any activity. The purpose of this paper is to examine the factors that actively contribute to the effectiveness of teams. This research looks at two different types of teams: care delivery teams representing healthcare and improvement teams representing the manufacturing industry. The aim is to provide greater knowledge about the application of team work factors in different environments. Design/methodology/approach -- Qualitative interviews about teamwork factors were conducted with 17 leaders of teams from healthcare and 22 leaders from manufacturing industries. The responses were categorized into different levels according to the application of each factor. Then, the factors were analyzed to draw conclusions about the different approaches to teamwork and their application. Findings -- Most of the factors analyzed are highly applied in both sectors. However, we found significant differences between hospitals and the manufacturing industry when it comes to factors such as strategies, feedback on results, leadership, participation and communication. Originality/value -- Measuring each factor in two different sectors (healthcare and industry) has yielded noteworthy findings and the best practices for their implementation

The purpose of this paper is twofold: to evaluate the importance of the factors reported in the literature as enablers of Continuous Improvement (CI) programmes and to determine the perception of managers of different companies in the Basque Country and Navarre (Spain) regarding the relevance of these factors to their improvement programmes. In total, 15 elements have been considered to be key issues for the sustainability of CI programmes. Semi-structured interviews were conducted with 36 companies in order to assess how the companies value the factors and how the factors are applied and measured. The findings regarding the application and evaluation of such factors have revealed that companies are focused on the agents associated with the achievement of results. Other factors, such as management commitment or the promotion of team working, are highly scored and applied, but few companies evaluate them or take actions to improve their application. This paper analyzes the application of some factors considered to be enablers or key factors for the sustainability of continuous improvement systems. Furthermore, it examines the mechanisms or indicators which are used by some companies to measure the application of those factors

Sectors associated with the distribution of products and goods have become more and more important in recent years. Globalisation and changing market demands are increasing competitiveness in these sectors, and as a result many companies have adopted new improvement methods to assure their survival. The adoption of improvement philosophies and a lean culture offer new opportunities to improve the quality and service of distribution networks and activities related with transport and warehousing. The application of these philosophies, widely used in industrial companies, has been little documented in distribution centres. However, these methods are difficult to implement in companies from the distribution sector due to the volatility of customer demand, the high degree of human participation and the demanding mechanical and repetitive activities in retail and storage activities. This paper presents a methodology for change management to adopt lean practices in distribution centres. The presented case study has been used to develop, test and refine the methodology. Results show that the methodology was suitable for establishing a lean culture in the company and it resulted in good outcomes in terms of productivity, employee attitudes and participation.

Purpose: The purpose of this paper is to see how quality management is carried out in hotels in the Basque Country, a region in the north of Spain with a long tradition in the tourist sector. Design/methodology/approach: The objective of the study was to establish what approaches to quality management are utilised by hotels in the region. The data were collated from information gathered via a survey conducted by e-mail. Findings : A large percentage of surveyed hotels implement a quality management system that has been designed in-house. A figure of note, is the fact that 79 per cent of participants claim their quality management system has been introduced successfully. The study also indicated that a significant number of hotels implement a policy of continuous improvement to the system, as hotels believe in the effectiveness of quality management systems and think that such systems have resulted in an increase in customers and profit. Originality/value: This study offers an understanding on the philosophy of quality management adopted by hotels in the Basque Country. Moreover, it provides empirical evidence on the perceived results of the implementation of quality management in hotels.

By means of a case study of an automotive manufacturer, this paper aims to study the impact of a continuous improvement (CI) programme on quality defects. The analysis aims to ascertain if several independent variables such as production, CIs, and shifts are correlated to each of two dependent variables: internal quality defects and auditor quality defects (detected in the line). We gathered daily data for each shift of internal quality and auditor quality in a 12-month period. The defects considered and analysed through this study amounted to more than 68,000. This analysis could be useful as a methodology to evaluate the CI programmes of other manufacturers, since there is very little literature in terms of case studies or examples that focus on the daily struggle that manufacturers face when transforming these strategies into working practices

Purpose ¿ Since the field of healthcare was a latecomer to the quality movement, knowledge transfer has generally flowed in one direction, from industry to healthcare. However, organisations can also be enriched by healthcare. In particular, this paper aims to show industry that important lessons can be learned regarding how teamwork is generally managed within healthcare. Design/methodology/approach ¿ To identify the useful lessons that healthcare can teach industry, the authors started with a brainstorming session among the members of the research team to pin-point the lessons based on their experience with healthcare and industrial environments. Afterwards, an exhaustive review of the relevant literature from the last ten years was carried out. Findings ¿ Industrial organisations need to develop teamwork frameworks focused on involving every employee in cross-disciplinary, empowered and trained teams. Moreover, from a team perspective, special care must be shown when defining clear roles, focusing on end clients, formulating shared objectives and facilitating internal communications. Practical implications ¿ The ten lessons from healthcare teamwork best practices believed to be the most important are given in the paper. Although some of these lessons may not be completely new concepts for industrial organisations, the paper shows how healthcare develops, spreads and applies these concepts in the real world. Originality/value ¿ The paper summarises, in ten useful lessons for organisations, healthcare's best teamwork practices in the literature

Equipment efficiency can be measured and improved by the availability, performance and quality rates provided by the overall equipment effectiveness (OEE) metric. Because today's managers operate in a complex manufacturing scenario, measurement systems play an important role in transforming data into decisions, and this task needs to be strengthened. Although sophisticated equipment and information technology systems are available, a methodology is required for understanding and managing data in order to make timely decisions regarding improvement. Thus, improvement needs to be supported by an easy-to-understand measurement system and a cutting-edge data-collecting technique. In order to assist not only managers and operators but also students and academia, this article presents a Plug&Lean system supported by a core element, the Plug&Lean wireless device, based on total productivity maintenance (TPM) and Lean methodology for providing a reliable diagnosis of the current state of equipment, to display graphical information about the equipment performance constraints towards to direct improvements activities. The aim of the Plug and Lean wireless device is to collect accuracy data with less effort from production equipment Two case studies are discussed to illustrate the applicability of the system.

Después de los planteamientos de Taylor y Ford, la industria japonesa, con su principal exponente Toyota, demostró que es posible tener un mayor nivel de flexibilidad y productividad a través de sus principios de Just in Time, polivalencia de la mano de obra, cero inventarios, producción en flujo continuo y mejora continua. Diversidad de conceptos, propuestas y hasta filosofías han surgido de las ideas originales de Taiichi Ohno y sus colaboradores y, en muchos casos, al querer ser implantados en la organización se pierde la esencia de lo verdaderamente importante. La finalidad de este artículo, resultado de una revisión bibliográfica sobre sistemas de mejora continua, es mostrar cómo interactúan los diferentes planteamientos desarrollados en torno al Sistema de Producción Toyota, y al mismo poner de relieve sus aspectos comunes y los puntos críticos a considerar en su implementación. Para tal fin, se ha recurrido a los conceptos originales de los principales autores como son Taiichi Ohno, Masaaki Imai, Hiroyuki Hirano, Shigeo Shingo, James Womack y Daniel Jones, todos ellos considerados gurúes de la mejora continua. Así, el artículo contribuye a una comprensión holística sobre la aplicación de los sistemas de mejora continua.Como síntesis conclusiva se extrae que, además del despilfarro considerado el centro de atención de los diferentes planteamientos, existe también un interés general por lograr la participación del personal en los programas de mejora a través del cambio de hábitos, capacitar permanente al personal en los fundamentos y técnicas sobre mejora, romper el círculo vicioso que asocia la mejora continua con la pérdida del empleo y, finalmente, generar un cambio de mentalidad como precondición al comenzar a implantar un programa de mejora continua. En este mismo sentido, la gestión de los procesos y el aprendizaje de las personas son dos aspectos que conducen, de manera interrelacionada, a que una organización mejore su productividad y competitividad.

After Taylor and Ford's approaches, the Japanese industry, with its main leading exponent Toyota, showed that it is possible to have a greater level of flexibility and productivity through its principles of "just in time, versatility of labor, any inventory, continuous flow production and continuous improvement. Diversity of concepts, proposals and even philosophies have arisen from the original ideas of Taiichi Ohno and his associates, however, when they are going to be implemented in a organization its key essence is lost. The purpose of this paper, result of a review of the literature on continuous improvement systems, is to show how different approaches developed around the Toyota Production System interact. At the same time to emphasize in their common and decisive points to consider in its implementation. For this task, it has to be turned to original concepts of the leading authors such as Taiichi Ohno, Masaaki Imai, Hiroyuki Hirano, Shigeo Shingo, James Womack and Daniel Jones. All of them known such as gurus in the field of continuous improvement. Thus, this article contributes to a holistic understanding on continuous improvement systems implementation. As a conclusion, besides the wasting considered the focus of attention of different approaches, there is also a general interest in engaging staff in improvement programs through the change of habits, permanent staff training in the improvement fundamentals and techniques, leaving behind the vicious circle that links continuous improvement with a condition of lacking work, and finally motivate a change of mind, create a climate of trust before starting to implement a continuous improvement program. In this sense, the management processes and the learning of employees working in harmony are two aspects that lead an organization to improve in both: productivity as competitiveness.

In the healthcare sector, teamwork is a key issue. Although the sector promotes research on improving the quality of teamwork, it rarely focuses on evaluating this process. This paper develops a methodological proposal for assessing teamwork effectiveness. The model considers 36 factors used to measure it, by observing the existence, importance and application level of these factors in the teamwork. The model was used to assess teams working in the public hospital network in the Basque Country (Spain). Methodology was of the exploratory type and developed with data obtained from interviews carried out according to a script based on the model's structure. The assessment was conducted through interviews in order to qualitatively assess the existence, degree and level of implementation for those factors. From applying the model to the practical case, conclusions are that most of the factors analyzed in those hospitals had medium and high scores; the lowest scores were for factors related to results, recognition, training and selecting team members.

As comfort has become an important factor in the lift industry, validated lift models are currently a significant research area. In this article, we present an analysis of a lift guiding system, which transmits vibrations to the cabin and affects passengers' comfort. The project consisted of determining the most important lift guiding system factors that affect a lift's comfort. The Design of Experiments technique was chosen as the best technique available to maximize the information gathered from the experiments. in order to carry out the experiments, a lift test rig was specially constructed in order to simulate a real installation. We screened and analyzed the influence of many factors on the response with an adapted factorial fractional design. This article shows the steps carried out in planning and analyzing the experiments, putting special emphasis on the planning during every phase of the DoE application. This research project was co-developed by a research center, a university and a well-known Spanish lift company. Copyright (C) 2009 John Wiley & Sons, Ltd.

An extensive literature review was carried out to detect why design of experiments (DoE) is not widely used among engineers in Europe. Once 16 main barriers were identified, a survey was carried out to obtain first-hand information about the significance of each. We obtained 101 responses from academics, consultants and practitioners interested in DoE. A statistical analysis of the survey is introduced, including: (a) a ranking of the barriers, (b) grouping of barriers using factorial analysis, (c) differences between characteristics of respondents. This exploratory analysis showed that the main barriers that hinder the widespread use of DoE are low managerial commitment and engineers' general weakness in statistics. Once the barriers were classified, the most important resultant group was that related to business barriers.

In the turbulent global environment in which organizations now compete, having reliable, accurate and readily available information is a key factor. Information is a strategic company resource. To the extent that TQM is an information-intensive management model, it is not unreasonable to assume that companies committed to TQM models should be efficient when managing information. This study has two main objectives. First, we aim to explore whether the information managed by companies committed to TQM models (in particular a quality management system based on the ISO 9000 international quality standards series) meets the dimensions required for information quality. Second, we aim to explore how information quality dimensions influence information consumers¿ overall feeling of being well informed in those companies. Using a quantitative approach, we used a questionnaire survey to capture the perceptions of managers in companies committed to a quality management system based on the ISO 9000 international quality standards series with respect to the information they managed. More specifically we applied a nonparametric test and performed a multiple regression analysis to address the objectives of the study. The analysis shows evidence that the information managed already meets many dimensions of information quality among the companies analysed.

Manufacturers have the challenge to increase productivity given complex manufacturing environments. A source that provides substantial levels of productivity is the overall equipment effectiveness (OEE) metric, which is an indicator to improve not only equipment utilization; but also the overall manufacturing operations, because of the valuable information that comes from the availability, performance and quality rates. Although information technologies have been introduced, companies use manually recorder data and have complicated measurement procedures. As a consequence, inaccurate information is generated and opportunities to improve productivity are missed. This paper presents a continuous improvement framework based on Lean manufacturing philosophy, operated by a system of wireless devices to support the real time equipment performance metrics. In order to validate the framework, results of a case study are exposed.

Manufacturers continue facing the never ending challenge of finding the best way to increase productivity levels in order to remain competitive. Significant level of productivity are given by the efficient utilization of production equipment, thus manufacturing companies use the overall equipment effectiveness (OEE) rate as an indicator to control equipment utilization related to the maintenance activity; however they do not take into account other valuable OEE-information to improve their entire manufacturing operations. This paper presents a continuous improvement model Plug&Lean-CiMo, whose aims are the accurate calculation of the OEE indicators, the appropriate classification of losses, and the systematic integration of lean manufacturing philosophy tools in an improvement methodology. The model has the advantage of using a portable wireless system to support the automated collection, of data to make the continuous improvement process easier. A case study is presented to illustrate the validation of the model.
