Service quality, customer satisfaction, and behavioral intentions in the service factory

Festus O. Olorunniwo; Maxwell K. Hsu; Godwin J. Udo

Purpose – This study seeks to investigate, through the development of an operationalized service quality construct in the context of a service factory, whether the typology to which a service belongs may explain the nature of the service quality (SQ) construct and its relationship to customer satisfaction (SAT) and behavioral intentions (BI).Design/methodology/approach – An exploratory factor analysis used a sample from undergraduate student respondents. Then, a more representative sample of hotel guests was used, in a second‐order confirmatory factor analysis.Findings – The dominant dimensions of SQ construct in the service factory were found to be: Tangibles, Recovery, Responsiveness, and Knowledge. Further results indicate that, although the direct effect of SQ on BI is significant, the indirect effect (with SAT playing a mediating role) is a stronger driver for BI in the context of the service factory.Research limitations/implications – A notable limitation is that the present study focuses only on th...

A typology analysis of service quality, customer satisfaction and behavioral intentions in mass services

Festus O. Olorunniwo; Maxwell K. Hsu

Purpose – This paper aims to investigate the possibility that the typology of a service as well as the operationalization of the service measurement scale may determine the nature of the service quality (SQ) construct and its relationship with those of customer satisfaction (SAT) and behavioral intentions (BI).Design/methodology/approach – The study utilized the service classification scheme developed by Schmenner and concentrated on the mass service category as an example to illustrate the concept with data from retail banking.Findings – Confirmatory factor analysis indicated that “Responsiveness,” “Tangibility,” “Reliability,” “Knowledge,” and “Accessibility” dimensions contribute significantly to service quality. It was further observed that SAT fully mediates the impact of SQ on BI.Research limitations/implications – A notable limitation is that the present study focuses only on mass service and uses only one industry (retail banking) to illustrate the findings. Future research should examine other se...

Information sharing and collaboration practices in reverse logistics

Festus O. Olorunniwo; Xiaoming Li

Purpose – The purpose of this study is to investigate how the use of information technology (IT) and supply chain management initiatives (information sharing and collaboration) impact a companys performance in reverse logistics (RL).Design/methodology/approach – A survey based on a previous exploratory research and literature review was sent out to 600 US companies having substantial activities in RL. Issues addressed in the survey, such as IT types deployed, IT operational attributes, information sharing, and collaboration, involve multiple parties in multi‐tier RL networks, extending beyond a simple buyer‐supplier dyad.Findings – The results revealed that the type of IT used per se did not have a differential impact on a companys performance in RL. However, IT operational attributes positively affected RL performance and information sharing and collaboration are critical to RL performance.Practical implications – Investment in IT alone cannot improve a companys performance; managers should take full ...

An exploration of reverse logistics practices in three companies

Xiaoming Li; Festus O. Olorunniwo

Purpose – This paper seeks to report a case study that focuses on identifying what may be considered a typical or generic RL process flow as well as the key strategic issues that a firm may use for competitive advantage.Design/methodology/approach – The research involves mainly interviews and plant visits to three companies, all of which manage some RL activities.Findings – Highlighted are what type of RL process flow can be considered as generic, the type of technology innovation and IT a firm needs in order to operate an effective RL system and how these are integrated across the supply chain, the resource commitment (personnel, financial, upper‐level management) that a company needs to make to support successful RL efforts, and finally, the values firms derive from RL and the key performance indicators to measure these values for the RL operations.Originality/value – A typical returns flow process is provided that can guide managers efficiently on their RL activities. Strategic activities are also pres...

A deterministic model for planning production quantities in a multi-plant, multi-warehouse environment with extensible capacities

Joel K. Jolayemi; Festus O. Olorunniwo

Abstract We have developed a deterministic model for planning production and transportation quantities in multi-plant and multi-warehouse environment with extensible capacities. The model determines a production mix that maximizes total profit over a finite planning horizon. When production cannot meet demand due to lack of adequate resources, the model allows shortfalls to be met through subcontracting or the use of inventory. However, it does not allow subcontracting when adequate resources are available. When solved, the model produces the quantity of each product to be: (1) produced at each plant, (2) transported from each plant to each warehouse, (3) subcontracted at each warehouse, and (4) kept in inventory at each warehouse. Furthermore, it identifies the warehouses that need extensions at any period and the corresponding amounts of extensions needed. We also develop a procedure for reducing the size of the zero–one MILP problem that can be obtained during any application of the model. Numerical examples given to illustrate the model and to compare the full and the reduced versions of the model show that the model works well and that both the full and the reduced versions produce exactly the same results. Finally, we discuss the assumptions underlining the model and highlight the approaches that can be taken to eliminate or, at least, prevent errors that are associated with violations of the assumptions.

THE IMPACT OF MANAGEMENT AND EMPLOYEES ON CELLULAR MANUFACTURING IMPLEMENTATION

Festus O. Olorunniwo; Godwin J. Udo

Abstract Several empirical studies have dealt with the impact of cellular manufacturing (CM) on employees’ attitudes, job satisfaction, morale, and quality of work life. While the understanding of the impact of CM on these characteristics allows practitioners to identify the undesirable effects to avoid during CM implementation, research is lacking on which desirable sociotechnical job characteristics have significant impacts on the success of CM implementation. This study uses the sociotechnical system (STS) principles to identify three major categories of variables that are likely to impact CM implementation namely top management role, job design for operators, and cross training. Three different exploratory regression models were used to identify subsets of the variables that have the most impact on CM success. The results indicate, among other things, that CM implementation seems to be more successful if top management initiates the CM project, and if employees are cross-trained to run various machines and read blue prints. In addition, CM success seems to be enhanced if jobs are scheduled and tracked within the cells.

Strategic partnering when the supply base is limited: a case study

Festus O. Olorunniwo; Tony Hartfield

This study considers a supply‐demand situation where a product has only a handful of supply firms and a large number of purchasing firms and compares the attitudes toward partnering of firms which are already in partnering relationships with those that are not. Noting that only 27 per cent of the buyers are currently in any alliance relationships, and most are not planning to be in one, the study reveals that buyers expressed a lukewarm, and sometimes negative, attitude toward the formation of alliances. There are no attitudinal differences between firms in alliance relationships, compared with those without, in five of seven questions on alliance and in the relative importance given 14 of 15 purchasing criteria. With most suppliers willing to provide the buyers with the same benefits, irrespective of whether they are in alliance relationships, it appears that the limitations imposed by the small supply base tend to exert competitive pressures on the suppliers, discouraging buyers from forming partnership relationships.

A FRAMEWORK FOR MEASURING SUCCESS OF CELLULAR MANUFACTURING IMPLEMENTATION

Festus O. Olorunniwo

This paper analyses a part of the data collected in a survey of US firms that operate manufacturing cells. The paper identified two underlying dimensions or constructs that explain the relationships amongst the performance measures commonly used to assess the relative magnitude of success of cellular manufacturing (CM) implementation. These are: (1) delivery response (D R), and (2) quality-cost (QC). Scrap-rework and throughput time were identified as appropriate surrogate measures respectively for QC and D R, indicating that those two variables may suffice to monitor success of CM implementation. The firms report significantly greater improvements in D R variables than they do in QC. The paper also proposes a methodology to categorize relative success of CM implementation. Noting that no manager would volunteer to categorize his implementation efforts as a failure, the categorization scheme proposed can be utilized regardless of the firms claims. Interpreting success within the framework of the proposed...

Scheduling Imperfect Preventive and Overhaul Maintenance

Festus O. Olorunniwo; Ariwodo Izuchukwu

Although each maintenance task performed on an item of equipment may enhance its reliability, neither preventive nor overhaul maintenance can return the equipment to good‐as‐new condition. Applying the concept of maintenance improvement factors to both types of maintenance, mathematical models are developed that are used to generate preventive and overhaul maintenance schedules. Examples are provided to demonstrate the sensitivity of the schedules to model parameters.
