Towards a model for the measurement of data quality in websites

Websites are, nowadays, the face of institutions, but they are often neglected, especially when it comes to contents. In the present paper, we put forth an investigation work whose final goal is the development of a model for the measurement of data quality in institutional websites for health units. To that end, we have carried out a bibliographic review of the available approaches for the evaluation of website content quality, in order to identify the most recurrent dimensions and the attributes, and we are currently carrying out a Delphi Method process, presently in its second stage, with the purpose of reaching an adequate set of attributes for the measurement of content quality.

An empirical assessment of customer satisfaction and quality of service: comparing SERVQUAL and SERVPERF

This paper assesses the validity and reliability of two instruments measuring quality of service, the SERVPERF and SERVQUAL scales, replicated in a novel cultural settings, a Portuguese energy company. To provide insights and strategies for managerial intervention, a relation between customers’ satisfaction and quality of service is established. The empirical study suggests a superior convergent and predictive validity of SERVPERF scale to measure quality of service in this settings when comparing to SERVQUAL. The main differences of this study with previous ones, are that this one resorts on a confirmatory factor analysis, the validation of the instruments is performed by using the same measures suggested by their creators and extends the line of research to a novel cultural settings, a Portuguese energy company. Concerning the relationship between service quality and customers’ satisfaction, all of the quality of service attributes correlate almost equally to the satisfaction ones, with a lower weight concerning tangibles.

On the survey results focus is on what meters and measurement systems companies use. It is also viewed what measurement problems companies have faced. In the applied part of the study harmonized performance measurement system is created. The framework of the measurement system is introduced and measurement system for the target company is created. The target company felt that the harmonized performance measurement system has good potential and continues to develop it further.

Measuring Cost of Poor Quality in Industrial Electronics

Quality is not only free but it can be a profit maker. Every dollar that is not spent on doing things wrong becomes a dollar right on the bottom line. The main objective of this thesis is to give an answer on how cost of poor quality can be measured theoretically correctly. Different calculation methods for cost of poor quality are presented and discussed in order to give comprehensive picture about measurement process. The second objective is to utilize the knowledge from the literature review and to apply it when creating a method for measuring cost of poor quality in supplier performance rating. Literature review indicates that P-A-F model together with ABC methodology provides a mean for quality cost calculations. These models give an answer what should be measured and how this measurement should be carried out. However, when product or service quality costs are incurred when quality character derivates from target value, then QLF seems to be most appropriate methodology for quality cost calculation. These methodologies were applied when creating a quality cost calculation method for supplier performance ratings.

Value added KPI service delivery with quality function deployment: Multiple case study in asset & real estate management

The aim of this study is to investigate value added service concept for an asset and real estate management case company. The initial purpose was to recognize the most value adding key performance indicators (KPIs) information delivered for its customers, real estate investors with value added service. The multiple case study strategy included two focus group interviews with five case interviews in total. Additionally, quality function deployment (QFD) was used in order to form up the service process. The study starts with introduction and methodology explaining the demand for the thesis study. The subsequent chapter presents the theoretical background on real estate management KPIs in four main points of views and quality function deployment from the service development point of view. The chapter also defines research gap for the case study. According to the case study interviews, the most favored KPIs to deliver for the clients are income maturity of lease agreements and leasing activity. These KPIs and quality characteristics are translated into the QFD. In total, the service QFD explains the service planning, process control, and action plan phases.

Quality cost in bus operations based on activity-based costing

The study of service quality and its implication for transport contracts has several approaches in research and practical applications, where the main emphasis is the consideration of quality from the user's point of view, thus obtaining a customer satisfaction index as a measurement of the overall quality with no further implications for service providers. The main aim of this paper is to estimate the real economic impact of improving quality attributes for a bus operator. An application of the activity-based costing methodology is developed for a bus contract in Madrid, using quality data from surveys together with economic and performance information, and focusing on headway as a quality variable. Results show the consistency and practicality of this methodology, overcoming simplifications from traditional procedures. This method is a powerful tool in quality-based contracting as well as for effective investment in transport quality under poverty funding constraints

Internalization of quality management in service organizations

Purpose – The purpose of this paper is to analyze the internalization of quality management (QM) on the basis of quality certifiable standards – also referred to as meta-standards – in service organizations. More specifically, the paper analyzes the case of the internalization of a quality standard in the Spanish hotel industry. Design/methodology/approach – The paper examines the relationships between the measures of internalization, benefit, QM tools and motivation, using partial least squares in the framework of the structural equation modeling technique. Findings – The results show that the hotels that have internalized the standard to a greater extent are more likely to be driven by internal motivation, develop more QM tools and achieve greater benefits than the hotels with a lower degree of internalization. Originality/value – As previous studies have examined these issues in relation to the internalization of ISO standards, the present study adds to this important stream of research and contributes by advancing the understanding of these issues through the case of a specific standard for the hotel industry.

Service acculturation:a dyadic study of managerial and employee effects upon service firm performance

The majority of previous research into service quality and services marketing has concentrated upon the measurement of service quality outcomes, rather than the enhancement of the process by which service is delivered. In this study a conceptual model of the service acculturation process is proposed, modelling the input of service managers and employees in the delivery of service quality to customers. The conceptualisation is then empirically tested utilising a dyadic study of the New Zealand hotel industry. Results indicate that 1) a strong commitment to service is important for both managers and employees; and 2) that employees’ teamwork may have an adverse effect on perceived quality of customer service. Implications of the results and future research directions are subsequently discussed.

Outcomes of service encounter quality in a business-to-business context

Service encounter quality is an area of growing interest to researchers and managers alike, yet little is known about the effects of face-to-face service encounter quality within a business-to-business setting. In this paper, a psychometrically sound measure of such service encounter quality is proposed, and consequences of this construct are empirically assessed. Both a literature review and a dyadic in-depth interview approach were used to develop a conceptual framework and a pool of items to capture service encounter quality. A mail survey of customers was undertaken, and a response rate of 36% was obtained. Data analysis was conducted via confirmatory factor analysis and structural equation modeling. Findings reveal a four-factor structure of service encounter quality, encompassing professionalism, civility, friendliness and competence dimensions. Service encounter quality was found to be directly related to customer satisfaction and service quality perceptions, and indirectly to loyalty. The importance of these findings for practitioners and for future research on service encounter quality is discussed.

Quality-driven resource utilization methods for video streaming in wireless communication networks

This research is focused on the optimisation of resource utilisation in wireless mobile networks with the consideration of the users’ experienced quality of video streaming services. The study specifically considers the new generation of mobile communication networks, i.e. 4G-LTE, as the main research context. The background study provides an overview of the main properties of the relevant technologies investigated. These include video streaming protocols and networks, video service quality assessment methods, the infrastructure and related functionalities of LTE, and resource allocation algorithms in mobile communication systems. A mathematical model based on an objective and no-reference quality assessment metric for video streaming, namely Pause Intensity, is developed in this work for the evaluation of the continuity of streaming services. The analytical model is verified by extensive simulation and subjective testing on the joint impairment effects of the pause duration and pause frequency. Various types of the video contents and different levels of the impairments have been used in the process of validation tests. It has been shown that Pause Intensity is closely correlated with the subjective quality measurement in terms of the Mean Opinion Score and this correlation property is content independent. Based on the Pause Intensity metric, an optimised resource allocation approach is proposed for the given user requirements, communication system specifications and network performances. This approach concerns both system efficiency and fairness when establishing appropriate resource allocation algorithms, together with the consideration of the correlation between the required and allocated data rates per user. Pause Intensity plays a key role here, representing the required level of Quality of Experience (QoE) to ensure the best balance between system efficiency and fairness. The 3GPP Long Term Evolution (LTE) system is used as the main application environment where the proposed research framework is examined and the results are compared with existing scheduling methods on the achievable fairness, efficiency and correlation. Adaptive video streaming technologies are also investigated and combined with our initiatives on determining the distribution of QoE performance across the network. The resulting scheduling process is controlled through the prioritization of users by considering their perceived quality for the services received. Meanwhile, a trade-off between fairness and efficiency is maintained through an online adjustment of the scheduler’s parameters. Furthermore, Pause Intensity is applied to act as a regulator to realise the rate adaptation function during the end user’s playback of the adaptive streaming service. The adaptive rates under various channel conditions and the shape of the QoE distribution amongst the users for different scheduling policies have been demonstrated in the context of LTE. Finally, the work for interworking between mobile communication system at the macro-cell level and the different deployments of WiFi technologies throughout the macro-cell is presented. A QoEdriven approach is proposed to analyse the offloading mechanism of the user’s data (e.g. video traffic) while the new rate distribution algorithm reshapes the network capacity across the macrocell. The scheduling policy derived is used to regulate the performance of the resource allocation across the fair-efficient spectrum. The associated offloading mechanism can properly control the number of the users within the coverages of the macro-cell base station and each of the WiFi access points involved. The performance of the non-seamless and user-controlled mobile traffic offloading (through the mobile WiFi devices) has been evaluated and compared with that of the standard operator-controlled WiFi hotspots.

Model and performance of a no-reference quality assessment metric for video streaming

Video streaming via Transmission Control Protocol (TCP) networks has become a popular and highly demanded service, but its quality assessment in both objective and subjective terms has not been properly addressed. In this paper, based on statistical analysis a full analytic model of a no-reference objective metric, namely pause intensity (PI), for video quality assessment is presented. The model characterizes the video playout buffer behavior in connection with the network performance (throughput) and the video playout rate. This allows for instant quality measurement and control without requiring a reference video. PI specifically addresses the need for assessing the quality issue in terms of the continuity in the playout of TCP streaming videos, which cannot be properly measured by other objective metrics such as peak signal-to-noise-ratio, structural similarity, and buffer underrun or pause frequency. The performance of the analytical model is rigidly verified by simulation results and subjective tests using a range of video clips. It is demonstrated that PI is closely correlated with viewers' opinion scores regardless of the vastly different composition of individual elements, such as pause duration and pause frequency which jointly constitute this new quality metric. It is also shown that the correlation performance of PI is consistent and content independent. © 2013 IEEE.

Az online fogyasztói elégedettségmérés hatása a vállalatok versenyképességére (Effect of the online-customer satisfaction’s measurement to the corporate’s competitiveness)

A versenyképes működés elengedhetetlen feltétele a fogyasztói elégedettség, melynek egyik meghatározó eleme az észlelt és elvárt minőség közti kapcsolat. A minőségi elvárások az internettel, mint napjaink egyik meghatározó csatornájával kapcsolatban is megfogalmazódtak már, így kapott jelentős szerepet az online szolgáltatás minőségének meghatározása, illetve ezzel összekapcsolódva az online fogyasztói elégedettségmérés. Jelen tanulmány első része szakirodalmi áttekintést nyújt az online szolgáltatás minőségének fogyasztói érzékelésével, értékelésével kapcsolatos elméletekről, melyek az online fogyasztók elégedettségmérésének alapját képezik. Ezután kerül sor a különböző mérési módszerek bemutatására, kiemelt szerepet szánva a szakirodalomban sokat tárgyalt E-S-QUAL és E-RecS-QUAL skálának. Az áttekintés középpontjában azok az elméletek állnak, melyek az online vásárlást is nyújtó honlapokra vonatkoznak. A cikk további része két empirikus kutatást tartalmaz. Az első az elégedettségmérés hazai helyzetét tárgyalja, a másik pedig a szakirodalomból ismert E-S-QUAL és E-RecS-QUAL skálákat felhasználva részletesen elemzi az elektronikus szolgáltatásminőség dimenziói és a fogyasztói elégedettség közötti fontosabb összefüggéseket, emellett röviden vizsgálja az alkalmazott skálák megbízhatóságát és érvényességét. A kutatás fő célja a gyakorlati szakemberek számára is releváns kapcsolatok feltárása és bemutatása. _______ A company’s competitiveness significantly depends on the satisfaction of its consumers, which is influenced by the relationship between the expected and perceived quality. As over the last decade internet has become a significant channel, in parallel its customers have built some expectation about the quality of different websites and online services. Therefore the marketing literature should focus on the dimensions of e-service quality (e-sq) and online-customer satisfaction. This study first resumes with different concepts of e-sq, which are the principles of the online-customer satisfaction’s measurement. Than the different e-sq measurement methods are reviewed and the dimensions of E-S-QUAL and ERecS- QUAL scales are deeply explained. The study is focusing on concepts relating to web shops. The next part of the article includes two empirical studies. The first is about the situation of satisfaction measurement at Hungarian companies. The other one analyzes the most relevant relationships between the dimension of e-sq and customer satisfaction based on the E-S-QUAL and E-RecS-QUAL scales for measuring e-sq and briefly outlines the reliability and validity of these scales. The main purpose of this empirical research is to summarise the managerial and practical implications.

Intelligent outcome measures in liaison psychiatry:essential even if not desirable. Commentary on... a multidimensional Framework for Routine Outcome Measurement in Liaison Psychiatry (FROM-LP)

Service development is guided by outcome measures that inform service commissioners and providers. Those in liaison psychiatry should be encouraged to develop a positive approach that integrates the collection of outcome measures into everyday clinical practice. The Framework for Routine Outcome Measurement in Liaison Psychiatry (FROM-LP) is a very useful tool to measure service quality and clinical effectiveness, using a combination of clinician-rated and patient-rated outcome measures and patient-rated experience measures. However, it does not include measures of cost-effectiveness or training activities. The FROM-LP is a significant step towards developing nationally unified outcome measures.

Quality improvement within nonprofit social service providers

As a relatively new phenomenon in 2009, Swedish nonprofit social service providers proposed quality improvement as a way to reduce mistakes, use resources more effectively and meet the needs and expectations of clients in a better way. Although similar experiences have been studied in health care, the transfer of quality improvement to nonprofit social services gives a possibility for more knowledge on what enables, and constrains, systematic quality improvement in this specific context. This thesis is based on five years of supporting quality improvement in the Swedish nonprofit welfare sector. Specifically, it builds knowledge on which active mechanisms and enabling or constraining structures exist for nonprofit social service quality improvement. By studying quality improvement projects that have been conducted in the development program Forum for Values, critical cases and broad overviews are found valuable. These cases have resulted in four papers on quality improvement in nonprofit social services. The papers include: critical cases from a nursing home for elderly and a daycare for disabled children (Paper I); a critical case from a sheltered housing (Paper II); an overview of performance measurements in 127 quality improvement projects (Paper III); and an analytical model of how improvement policy and practice are bridged by intermediaries (Paper IV). In this thesis, enabled or constrained events and activities related to Deming's system of profound knowledge are identified from the papers and elaborated upon. As a basis for transforming practice into continuous improvement, profound knowledge includes the four knowledge domains: appreciation of a system, theory of knowledge, understanding of variation and psychology of change. From a realist perspective, the identified events are seen as enabled or constrained by mechanisms and underlying regularities, or structures, in the context of nonprofit social services. The emerging mechanisms found in this thesis are: describing and reflecting upon project relations; forming and testing a theory of action; collecting and displaying measurable results over time; and engaging and participating in a development program. The structures that enable these mechanisms are: connecting projects to shared values such as client needs; local ownership of what should be measured; and translating quality improvement into a single practice. Constraining structures identified are: a lack of generalizable scientific knowledge and inappropriate or missing infrastructure for measurements. Reflecting upon the emergent structures of nonprofit social services, the role of political macro structures, reflective practice, competence in statistical methods and areas of expertise becomes important. From this discussion and the findings some hypotheses for future work can be formulated. First, the identified mechanisms and structures form a framework that helps explain why intended actions of quality improvement occur or not. This frameworkcan be part of formulating a program theory of quality improvement in nonprofit social services. With this theory, quality improvement can be evaluated, reflected upon and further developed in future interventions. Second,new quality improvement interventions can be reproduced more regularly by active work with known enablers and constraints from this program theory. This means that long-lasting interventions can be performed and studied in a second generation of improvement efforts. Third, if organizations integrate quality improvement as a part of their everyday practice they also develop context-specific knowledge about their services. This context-specific knowledge can be adopted and further developed through dedicated management and understanding of variation. Thus, if enabling structures are invoked and constraining structures handled, systematic quality improvement could be one way to integrate generalizable scientific knowledge as part of an evidence-creating practice.
