Development of lean production system using value stream mapping approach: A case study
by NAVEEN VIRMANI, Vikram Sharma
Abstract: Intense competition in global market is encouraging management to search for new ways to reduce cost and improve profits. Manufacturing firms are realizing that cost reduction through waste elimination can improve their competitive potential. Lean production concepts can be employed for waste elimination. However, managers find it difficult to identify the key areas for waste elimination. The field of lean production has offered VSM as a visualization tool to identify waste elimination opportunities. Using this tool, it is possible to map the current state and accordingly analyze for achieving waste elimination. In order to illustrate this aspect, the case study presented in this paper shows the way the firms can apply VSM for identifying the potential areas for applying this waste elimination technique. The purpose of this research is to examine value stream mapping (VSM) implementation in a gear manufacturing company located in national capital region of India. The case study shows that the production time, inventory and defects can be reduced significantly. Thus, VSM assists the managers to envisage the current level of wastes occurring in an organization and the future means of eliminating them.

by Shyam Murali C, Prabukarthi A
Abstract: The objective of the study is to improve productivity of a furniture manufacturing company. Demand forecasts play a crucial role in productivity, improvement and production planning analysing the problems associated with it and there by tackling over production and shortage. Demand forecasting was analysed using three (Simple moving average method, weighted moving average method, Seasonal regression method) different methods in which seasonal regression was found to be more accurate for the current scenario. This method reduces the deviation of forecast by 17.37% which will result in better visibility thus by improvement in productivity. Preliminary survey showed that there were some processes that lead to overall increase in production lead time and industry is not keen in operating the second shift particularly in painting department, which leads to under-utilization of resources. This research work opted for an exploratory study using the Time study analysis and Value stream mapping(VSM) to identify bottleneck processes. Brainstorming session was conducted to plot cause and effect and there by priorities the causes to tackle. Simulation analysis was performed to understand the utilization of man-machine using the current and alternative method. The proposed methods improve the operator utilization to 54% from 29% and output by 50%.
Transformational Leadership as an Antecedent for Organizational Commitment and Job Performance in the Banking Sector of Jordan
by Mohammed Iqbal Al-Ajlouni, Nawaf Alghusin
Abstract: Guided by social-exchange-theory, present study examined transformational leadership (TL) as an antecedent for organisational commitment (OC) and its subsequent influence on job performance (JP). Through using a structured self-administered questionnaire, data were collected surveying (439) non-executive employees operating in (15) banks listed in Amman-Stock-Exchange through non-probability purposive sampling. Structural-equation-modelling using SMART-PLS was utilised and the result reported that TL components achieved 44%, 42.5% and 35.4% of the variance in affective, continuous and normative commitment respectively. Idealised influence did not have any significant effect on any level of OC, whereas intellectual stimulation influenced the three levels of OC. Individualised consideration influenced only affective and continuous commitment, and inspirational motivation influenced only normative and continuous commitment. Moreover, only affective commitment was significant in influencing JP and accounted for 82% of the variance. Following the results, discussion and implication were provided. Also, directions and suggestions for future researches were presented.

Dynamic Slicing of Aspect-Oriented Software: An UML-based Approach
by Jagannath Singh, Abhishek Ray
Abstract: In this paper, we propose a technique to compute the dynamic slice of UML models for aspect-oriented software. The UML architectural model for aspect-oriented software represents the core components, aspectual components and the relationship between them. Firstly, we construct aspect-oriented model dependence graph (AOMDG) as an intermediate representation of the UML model for aspect-oriented software. AOMDG is a combination of aspect-class dependence graph (ACDG) and aspect-sequence dependence graph (ASDG). ACDG is constructed by using a set of class and set of aspect class diagrams and ASDG is constructed by using a set of sequence and aspect sequence diagrams from the UML architectural model. Then, we propose an algorithm to compute the dynamic slice by traversing AOMDG by marking and unmarking the nodes for a particular scenario during run-time.

Assessment of Sand Reclamation Techniques and Sand Quality in Thermal Reclamation
by Suyog B. Rayjadhav, Digvijay A. Mhamane, Vasudev Shinde
Abstract: In foundry, sand-moulding takes maximum share of production than other moulding methods. So the foundry requires huge quantity of sand daily. To safeguard environmental issues it is necessary to reuse the sand repeatedly otherwise it also increases disposal cost. In view of increasing demand from environmental and economic aspects, the assessment of sand reclamation systems becomes outmost importance. This study illustrates the various sand reclamation techniques like dry, wet, thermal, cryogenic and microwave reclamation in term of their procedure and assessment. The thermal sand reclamation system is developed comprising of sub units like fluidised bed combustor and fluidised bed sand cooler for 20 kg sand capacity and tested for chemically bonded sand casting. In the present study, developed thermal sand reclamation system is tested and results are compared with different sand reclamation systems. The no-bake-sand can be satisfactorily reclaimed by newly developed thermal sand reclamation technique with appropriate sand quality.

Matrix Based Tolerance Analysis for Multi-Component Selective Assembly with Geometric and Dimensional Features using Genetic Algorithm
by A.K. Jeevanantham, Chaitanya S.V, Rajeshkannan Ananthanarayanan
Abstract: Tolerance analysis (TA) is a method of investigating how the geometric and dimensional tolerance (GDT) deviations in each component propagate and affect the functional requirements of the product. Total deviation in an assembly fit can be controlled by selecting the components of the assembly through a purposeful strategy, called selective assembly (SA). In this paper, the matrix model of TA is applied in SA. The surface-based and shape closure analyses are done using the principles of TTRS and MGDE, and the assembly fit is modelled in terms of displacement matrices. The conventional method of dividing the components into groups only by the deviation on dimensional tolerance (DT) alone is replaced by integrated GDT. The effect of rotational displacements in component features on assembly fit is verified. A two-dimensional, worst case, rigid TA in SA is demonstrated. The best combinations of assembly components are obtained through genetic algorithm.

Leagile manufacturing paradigm in the production of jet pump
by K. Balakrishnan, S.R. Devadasan, Thilak VMM, D. Selvi Soundaram
Abstract: One of the types of pumps that find high demand from the customers is jet pumps. Today, pump manufacturing companies are required to produce conventionally designed jet pump as well as improved and innovative forms of the same to meet the demand of several customers. This kind of demand can be fulfilled only when leagile manufacturing paradigm is implemented around the production of jet pumps. In order to have a successful implementation of the same, while pursuing the research reported in this paper, a model named as 'pumping for leagility' (PFL) was designed and applied in the case of producing jet pumps in a typical Indian pump manufacturing company. The PFL model has eight steps comprising of 31 activities. By applying PFL model, the nuances of developing leagile manufacturing paradigm in real-time practice was examined and the extent of implementation in the production of jet pump was studied.

Empirical Study of the Performance of Ontarios Pulp and Paper Mills Using Bootstrap Data Envelopment Analysis
by Mohamed Dia, Shashi Shahi
Abstract: Ontario's pulp and paper mills have been facing extreme competitive pressures due to declining markets and low-cost competition from around the world, which have affected their performance and relative technical efficiency. This study uses a non-parametric technique, bootstrap data envelopment analysis, in analysing the operational efficiency of 23 pulp and paper mills in Ontario with sample data collected over a period of 17 years (1999 to 2015). The results indicate low levels of efficiencies due to the management of operations as well as the scale of operations, especially during the economic downturns. In addition, we noticed regional differences in the operational efficiencies of these mills. These results provide comprehensive details to mill managers to reallocated future resources.

Modeling Construction labour productivity using Evolutionary Polynomial Regression
by Zahra Zangenehmadar, Sasan Golnaraghi, Sabah Alkass, Osama Moselhi
Abstract: Construction projects are labour-intensive and labour costs are a substantial percentage of total budget. Impaired labour productivity causes an increase in construction project schedule. Labour productivity is one of the most frequently discussed topics in the construction industry, and modelling labour productivity by utilising different techniques has been getting more attention. It is a challenging task as it requires identifying the influencing factors as well as considering the associated interdependencies. This paper investigates the application of evolutionary polynomial regression (EPR) for modelling labour productivity in formwork installation. EPR is a data-driven hybrid modelling technique based on evolutionary computing and has been successfully applied to solving civil engineering problems. Results obtained from the EPR model were compared with the outcomes of three other methods: best subset, stepwise, and general regression neural network (GRNN). Results demonstrate the predictive superiority of the developed EPR model for nonlinear problems based on statistical performance indicators.

AN APPLICATION OF THE KANO MODEL AND RETAIL SERVICE QUALITY SCALE (RSQS) TO VIETNAMESE SUPERMARKETS
by Thu Ha Nguyen
Abstract: This paper presents the results of a study applying the Kano model for analysing, classifying, and prioritising customers requirements in the context of Vietnamese retail service. A questionnaire based on the retail service quality scale and Kano question form has been designed and collected data from 598 customers of Vietnamese supermarkets. The data has been analysed by Kano model and presented on the four quadrants of X, Y scatter. Analysis results indicate that among the 27 retail service quality attributes, 11 attributes are classified as must-be; five attributes for one-dimensional and seven attributes for attractive. Findings not only provide insight into how Vietnamese supermarket managers would satisfy and delight their customer satisfaction, gain the advantage competitive, and differentiate with their competitors but also prove that Kano model could be well applied with RSQS in the context of retail service environment.

What is the Role of Expert Intuition in Process Control?
by Venkat Pulakanam, Mark D. Hanna, Dirk Pons
Abstract: Rules of statistical process control (SPC) suggest that processes should not be adjusted by workers without an explicit data-driven management directive. By contrast, in many workplaces, workers are empowered to improve processes and seen as uniquely knowledgeable due to their experience in close proximity to the process. Thus, it absolutely is expected that operators will commit acts of personal agency as they apply their expert intuition. Based on observations of industry practice, we develop a description of expert intuitive process control (EIPC) and a conceptual framework which enables comparison of this approach to SPC and development of postulates regarding the contexts in which each approach is likely to be valued from a practical perspective.
Keywords: Statistical process control (SPC); personal agency; tacit knowledge; expert; intuition; Expert Intuitive Process Control (EIPC).
Productivity and Quality improvement through DMAIC in SME
by Janardhan K. Reddy, Soundararajan Krishnasamy
Abstract: During the past three decades, researchers have been advocating the application of define-measure-analyse-improve-control (DMAIC) phases of Six Sigma concept to achieve productivity and quality improvement in small and medium enterprises (SMEs). In this context, the research reported in this paper was carried out in a SME by applying DMAIC phases in the production of the castings of a component called balance weight. While executing the DMAIC phases, it was found that green sand moulding process had to be replaced with shell moulding process to avoid the increase in hardness and rejection of castings due to pin hole defect. On implementing this solution, the productivity increased by 50.42 units per hour and the quality level increased from 3.2 sigma to 4.4 sigma. Altogether, it was found that DMAIC can be used in SMEs to achieve productivity and quality improvement so as to acquire competitive strength.

Patient satisfaction in hospital emergency services: A perspective from the Portugal.
by Daniel Ferreira Polonia, Rui Diogo S. Santos, Ana A. C. Dias
Abstract: This research paper constructs and validates a conceptual model that identifies the determinants of patient satisfaction with hospital emergency services. The conceptual model is based on an extensive review of the literature on the subject and was validated by 400 interviews in four Portuguese NHS hospital emergency services. Analysis of the data revealed that there are five statistically significant variables that influence satisfaction, whereas satisfaction itself influences the loyalty dimension of the model. Although the sample was diverse and a significant number of patients were interviewed, the study only involved NHS users from one specific region of the country. Nevertheless, it proved possible to use the model to draw several managerial implications and these were analysed for ways in which patient satisfaction with the service could be improved.
Keywords: Service quality management; hospital emergency services; patient satisfaction; patient loyalty; healthcare services.
Defining the weights of the EFQM excellence model criteria for different business sectors
by Yannis Politis, Evangelos Grigoroudis
Abstract: EFQM model is Europes most prestigious award for organisational business excellence given to the best performing organisations in Europe. The aim of this paper is to propose a multicriteria approach to assess the weights of the models criteria based on the specific needs of different business sectors. For this reason a two stage process is proposed. In the first stage, criteria weights are assessed according to the rankings of a set of organisations with different scores on the EFQM excellence model criteria given by business experts from specific sectors or and participants of the quality award. The second stage concerns modifications and additional information or restrictions given by EFQM experts in order to improve the robustness of the preference model estimated from the previous stage. Considering that little can be found in literature concerning a general methodology for the construction of sector
specific models, the paper proposes a general approach to adjust the weights of the EFQM model criteria to better fit the specific needs of different business sectors.

Risk analysis on the current design of wooden-hulled boats with outrigger using fuzzy FMEA
by Miriam Bongo, Junny Ann Inot, Claitee Sebios
Abstract: In constructing wooden-hulled boats with outrigger, it is imperative to consider design factors that relate to safe operating conditions and sustainability. However, there exists no set of design failure modes in the literature specific to that of wooden-hulled boats with outrigger, thus, making it difficult for stakeholders of the maritime domain to understand fully the risks present in its design and construction. Therefore, this paper applies fuzzy FMEA to assess the risks involved in the design and construction of wooden-hulled boats with outrigger. The proposed methodology is applied in the Philippines, and it is found that high priority should be provided to failure modes pertaining directly to the type of wood used, being the primary component of wooden-hulled boats with outrigger, followed by failure modes specific on the design aspects. With such results, stakeholders are better facilitated on policies to be implemented to achieve an efficiently designed wooden-hulled boat with outrigger.
Keywords: wooden-hulled boat with outrigger; fuzzy FMEA; risk analysis; safe boat operations.
Cable Insulation Productivity Improvement using Lean Six Sigma
by Fikri Dweiri, Samar Ishaq
Abstract: Nowadays organisations are finding innovative ways to improve customer satisfaction and increase profitability. This can only be possible if they continuously and effectively improve their products and processes. The purpose of this study is to improve cable insulation process using Lean Six Sigma (LSS). Define, measure, analyse, improve, and control (DMAIC) and failure mode effect and criticality analysis (FMECA) were used to identify one of the critical problems which is break and crack in insulation layer of cables in a case company. The design of experiment (DOE) was used to reduce the occurrence of break and crack in cable insulation. Three main factors (supplier, temperature and pressure) each with two fixed levels were considered. The result showed that supplier and temperature are the only significant main factors at the 95% significance level. All interaction levels were not significant as well as the pressure main factor. The results show that risk priority number (RPN), which is an indicator for productivity improvement, was reduced from 745 to 205. Also the experiment produced fewer defects that lead to improve productivity.
Keywords: Performance improvement; production line; lean six sigma; FMECA; RPN.
Interactions Dynamics between the Performance Management System and the Quality Management System
by Mira Thoumy, Marie Hélène Jobin
Abstract: The purpose of this study is to characterise the dynamics between the performance management system (PMS) and the quality management system (QMS). We conducted a comparative case study between two university medical centres. We interviewed 41 participants from eight sub-units of analysis. We also conducted seven hours of meeting observations, 16 hours of management observations as well as a review of 46 documents that were submitted to us by the workers. Our results show that there are four types of possible interactions between the PMS and the QMS which are independence, antagonism, communication and collaboration. Moreover, there are three realms of interactions being the realms of structure, identities and practices. We found that the PMS and the QMS interact more in clinical units. The support services do not have well-developed performance and quality management. Also, the workers involved in operations are disconnected from the concept of performance.

An internal cooperation as a driver of total quality management
by Gun Jea Yu, Hojin Jung, Kyoung-min Kwon
Abstract: Much evidence has been presented on the critical factors for total quality management (TQM) and its effect on firm performance. Studies aiming to understand TQM have examined the moderators on the relationship between TQM and firm performance. Among these moderators, cooperation among teams and departments has been highlighted but rarely empirically tested. Thus, the paper investigates the conditions under which the effect of TQM is intensified using a sample of 565 firms in Korea. We confirmed that TQM is positively associated with firm performance. In addition, the cooperative internal environment, including the levels of cross-functional team (CFT) and of collaboration between R&D and manufacturing departments (CRM), positively moderates the relationship between TQM and firm performance. This study contributes to the current literature on TQM by considering and testing the moderating effects of collaboration environments.

A REVIEW ON SHORT-RUN UNIVARIATE QUALITY CONTROL APPROACHES
by Jeng Feng Chin, Chin-Kok Koh, Shahrul Kamaruddin
Abstract: Short-run control charts are used in situations where limited or no data exist about the process, and conventional statistical process control (SPC) charts are considered ineffective for estimating parameters, such as control limits, because they cannot be established in most cases. This study presents a contemporary review on developing various short-run univariate quality control approaches. Considerable literature is systematically collected on the basis of content analysis. Techniques are differentiated on the basis of repetitive and non-repetitive processes. Subsequently, the principles, data sample collection, performance criteria, robustness and applications of quality control approaches are reviewed.
Keywords: statistical process control; short-run; univariate; control chart.
Ripple effect of moral hazard: How do CSR misconducts impact firm performance in the dairy industry?
by Xiaohua Meng, Yunli Zhu, Meiling Zhong
Abstract: In this article we study how collective corporate social responsibility (CSR) misconduct affects the market performance of enterprises in the dairy industry. We do this by revisiting the melamine-tainted milk powder event in China. By comparing pre- and post-event retail data of three different types of infant milk powder manufacturers, as well as by analysing the cumulative abnormal returns (CARs) of those milk powder companies listed on stock markets, based on an event study approach, the ripple effect of China's melamine incident as an exogenous shock was investigated. The results show that industrial CSR misconduct has a suppression effect on the enterprises involved, overlapping suppression and spillover effects on domestic enterprises that were not involved, as well as spillover effects for foreign peers. Lessons from the melamine contamination incident and its policy implications should be valuable in promoting the CSR level and sustainability of other similar fast-growing industries in developing countries.

by Hayat Lionboui, Fouad Elame, Abdelghani Boudhar, Rachid Hadria, Brahim El Boukari, Tarik Benabdelouahab
Abstract: In order to improve socio-economic conditions in rural areas, the purpose of this study is to develop models for estimating wheat yield based on the use of agricultural inputs. The emphasis is not only on increasing production, but on economically efficient production that optimises productive resources. Thereby, a cost efficiency analysis for wheat producers was conducted based on a sample of 111 farmers in the Tadla Plain in central Morocco. To achieve this objective, two models devoted to wheat yield estimation in terms of costs and quantities of agricultural inputs were developed, based on stepwise regression approach. Furthermore, data envelopment analysis (DEA) method was used to analyse the cost efficiency of farms. Overall, this work separates the excess costs related to technical efficiency and economies of scale to cost efficiency in order to understand the type of actions that farmers can take to reduce production costs and ensure their resilience.

Firefly Enabled Agility Assessment in Manufacturing Systems
by Saleeshya P.G, NITHESH R, SANESHKRISHNAN K, SAIKRISHNA S
Abstract: The manufacturing processes have now evolved from dinosaur type of enterprise to lizard type known as agile manufacturing. Agility can be enhanced with some trivial change in firm's processes. In this study, an effort has been made to obtain the agility index of two different firms with their currently implemented agile enablers'. The two industries were identified based on the demand pattern, i.e., seasonal and volatile demand. The methodology of AHP is used to obtain effectiveness of the agile enablers. These effectiveness values are given as input to the FA to obtain the agility index in terms of 'response time between market and industry. Based on the results, the firms' can focus on the enabler with least response time to improve business performance through appropriate strategies. The response time of fashion firm is less than that of core-manufacturing firm. Hence fashion firms are more agile than core firms.

Co-deployment of quality standards: A systematic literature review
by DAHAR Hind, Ounsa Roudies
Abstract: Within a competitive environment marked by strong technological evolution, organisations have to be compliant at the same time with several repositories, norms or standards relating to quality of their processes continuous improvement. Diversity of standards can lead to different issues such as heterogeneity, redundancy and also increasing costs for their implementation in terms of time, resource mobilisation and budget. To solve these problems, the idea is to establish an alignment approach that guarantees the high level of quality wished by using several standards simultaneously. This article is a systematic review of literature specific to methods of alignment of norms and quality standards. We raise the problems caused by lack of alignment, and review existing approaches and their results.

QUALITY AND PERFORMANCE IN SMALL ACCOUNTING FIRMS
by Bjørn Willy Åmo, Lars Kolvereid
Abstract: The purpose of this study is to investigate the relationship between three central dimensions of quality in small accounting firms and firm performance. The three dimensions of quality investigated are: human resource (HR) quality, information technology (IT) quality and service quality. Firm performance is measured in two different ways: perceived performance and return on sales (ROS). We tested the hypotheses in a sample of 506 small Norwegian accounting firms. The results indicate that service quality relate positively to perceived performance and ROS. Human resource quality is positively related to perceived performance, but not ROS.

Evaluation of Quality cost in a multinational company located in Tangier, Morocco
by Mohamed B.E.N. ALI, Dina BAGHDADI MAZINI, Said Barijal, Insaf GHAILANI
Abstract: This study aims to evaluate the cost of obtaining quality (CoQ) of a multinational company in Tangier specialised in wiring. It also tries to identify the measures that can reduce the cost of non-quality and improve productivity time and there by improve competitiveness. According to our study, the CoQ represents 14.5% of the turnover including 10.4% of non-quality (internal and external failures). An analytical study was carried out concerning the quantification of all the components constituting the internal anomaly. It showed that machine stops have a significant effect on the increase of internal failures. To detect the main causes of non-performance, DMAIC, SMED and AMDEC approaches were used to decrease non-productivity time. This allowed the company to gain 41.3 days/year relative to each machine, which contributed to increase productive time and to generate an annual financial profit of 361370.24 euros (as a reduction of the non-quality cost of 6.36%).
Keywords: COQ; Performance; DMAIC; Poor quality; AMDEC; SMED; Time of productivity.

by Vinícius Lemos, Vitor Bernardo, Ana Honda, Mateus Gerolamo, Cesar J.C. M. Costa, Andrew M. Bacelar, Leonardo P. Ruli, Matheus S. Dall\\'Agnol
Abstract: Healthcare organisations face many challenges regarding market competitiveness, client expectations and regulatory demands. Quality management systems (QMS) have emerged as effective support tools for managers and the demand for ISO certification has increased. However, the process of diagnosing the QMS before certification is often complex, time-consuming and expensive. This article proposes a framework for QMS evaluation consisting of a diagnostic tool for blood banks. The methodology combines a set of international quality standards, change management principles and process mapping tools. It can be applied through internal audits, thus it is useful for organisations that seek relevant certification to define the next steps to be taken for improvement. A case study in a Brazilian blood bank illustrates the results of the framework. The pilot of the diagnostic tool was successful in identifying gaps that required further development by presenting maturity levels for each requirement of the international standards.

by Arash Shahin, Namatolah Mohseni, Ahmad Reza Shakarchizadeh
Abstract: The aim of this study is to identify the conformity level between decision-makers' perception of customer needs and indicators of satisfying customers. For this purpose, the marketing and sales department of Esfahan Steel Company (ESCO) was selected for case study. The statistical population of this study included clients and decision makers. Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) was used for data analysis. Main findings revealed that decision makers do not properly understand clients' demands and expectations; and the actions have been taken based on imaginations rather than realities arising from customers' expectations. Furthermore, there is no suitable process through which the customer priorities influence organization's strategies. Customers' expectations were ranked and the results were taken for proposing priorities in developing suitable strategies and plans for continuous improvement.

Effort estimation of Web based projects: A systematic Review
by Dhiraj Kumar Goswami, Saurabh Bilgaiyan, Samaresh Mishra
Abstract: Lately, the importance of effort estimation of web-based projects has increased. Due to the web project's dynamic changes, it becomes more difficult to use a particular estimating method. According to The CHAOS Report1994, only about 16.2% of the web projects are successfully developed in a given budget and time. In the first half of this study, we have provided a systematic analysis of the effort estimation of web-based projects. This would be useful for users to gain more knowledge on effort estimation in web-based projects since very few research works have been carried out in this field. Nowadays, web projects are more complex and data-centric. So, the inclusion of the database in the estimation process becomes necessary. Secondly, we proposed an estimation model, where the database is taken into consideration for its effort estimation. The result that we found after utilising the model gave more accurate effort estimation.

by M. Santhose, V. Senthil, S.R. Devadasan, K. Balakrishnan
Abstract: Right from the days of their release, ISO 9000 series standards-based quality management system (QMS) has been implemented in large number of organisations. Whenever revisions were made, organisations tuned their QMS to adhere to the respective revised version of ISO 9000 series standards. This kind of need has arisen now due to the release of ISO 9001:2015 standard. In the context of observing this need, the survey reported in this paper was carried out with the objective of exploring the nuances of ISO 9001:2015 standard and its implementation trend in organisations. The results of this survey have indicated that the organisations are now slowly turning their QMS to adhere to the stipulations of ISO 9001:2015 standard. Further, in this article, the need of integrating total productive maintenance (TPM) with the ISO 9001:2015 standard-based QMS is pointed out. This article is concluded by claiming that such integration and its implementation will enable the modern organisations to attain world class manufacturing goals.

Proposal of a causal model to measure the impact of quality on industrial performance: A case study from Moroccan context
by Mohamed B.E.N. ALI, Saif Rifai, Said Barijal, Otmane Bouksour
Abstract: This article aims to measure the impact of quality practices (summarized in five practices: Leadership, Strategy & Planning, Human Resources, Partnerships & Resources, Process Management) on the overall performance (summarized in four axes: Customer, financial, Internal Process, organizational Learning) of the young manufacturing enterprises in the growth phase. Using structural modeling on a sample of 80 enterprises, we concluded that, generally, quality practices positively impact the overall performance. However, an invalid link was detected between ''Human Resources'' and ''Management Process". Also a weak association was noted between ''Partnerships & Resources '' and ''Management Process''. It should be noted as well, that these two practices (''Human Resources and ''Partnerships & Resources'') had little indirect impact on performance. Indeed, to further improve the performance of the young enterprises, the owner-managers of such enterprises must seek constant improvement of quality practices especially those that have weak associations: ''Human Resources'' and ''Partnerships & Resources''.

Productivity Growth in Indian Telecommunications Equipment Industry
by Dipayan Datta Chaudhuri, Aashish Yadav
Abstract: This study has analysed whether the high growth rate in telecommunications service sector has a favourable impact on productivity growth rates of the telecommunications equipment industry in India. In this study, the total and partial factor productivity growth rates are measured for the telecommunications equipment industry during 19992016. The translog index is used to estimate the total factor productivity (TFP) growth rate of this industry in a five input KLEMS framework. The period of study is divided into two sub-periods, i.e., 19992007 (sub-period I) and 20082016 (sub-period II). The annual growth rate of total factor productivity is estimated to be 3.56% in sub-period I and 2.22% in sub-period II. It has been observed that the growth rate of gross value added (GVA) has decelerated between two sub-periods as the industry has become more import-centric due to implementation of the information technology agreement.

Waste Analysis Framework for Lean Production: Pilot Study in a Healthcare Setting
by Seyed-Hadi Mirghaderi, Zahra Akrami, Ali Naghi Mosleh Shirazi
Abstract: This paper utilises the constructive research approach for developing a systematic and step-by-step waste analysis framework. The purpose is to facilitate the implementation of lean operations in organisations. The suggested framework consists of seven steps: 1) finding the cause of wastes, 2) finding solutions, 3) diagramming the relationship among wastes, causes, and solutions, 4) estimating the cost of wastes, 5) determining the weight of wastes, 6) clustering wastes and 7) ranking waste clusters. By implementing the proposed framework in a hospital ward, which tends to be a lean healthcare system, we found that there are three clusters in 20 wastes. Then, we ranked the clusters concerning the cost and importance of the wastes. Real-world results confirmed that this method has the capability of providing a scientific way for the selection of a cluster of wastes with higher priority than others and subsequently, facilitating removal of the cluster.

On Modeling the Determinants of Total Factor Productivity in the MENA Region: A Macro-Micro Firm-Level Evidence
by Chahir Zaki, Nesreen Seleem
Abstract: Using enterprise surveys for MENA countries, this paper estimates total factor productivity (TFP) and examines its determinants. Our contribution is twofold. First, we provide TFP estimates by country and sector for the MENA region and examine how TFP changes by export status, age, firm size, formal status and ownership. Second, we combine both micro (firm level) and macro (nation level) determinants of TFP. Our findings show that among micro determinants, owning a foreign certification is positively associated to TFP. Yet, macro determinants (trade policy and institutions turn to be more important than micro ones.
