Despite the widespread organisational adoption of e-procurement systems, we continue to witness disappointing performance outcomes from their implementation. This can be explained largely by the failure of many organisations to translate the initial adoption decision, made at an organisational level, into individual-level acceptance of e-procurement by an organisation’s employees. The purpose of this paper is to examine the key antecedents of the technology acceptance model (TAM) for employees expected to use e-procurement systems in their day-to-day activities.

In this study, the authors apply and extend the TAM to examine the factors that influence the acceptance of e-procurement by individual employees. The authors’ focus is on the potential role of user-perceived e-procurement quality dimensions as the antecedents to the TAM’s cognitive mechanisms of perceived usefulness and perceived ease of use. The structural equation model uses the survey data collected from 139 e-procurement users at a university in the Netherlands.

The results confirm the core TAM relationships within an e-procurement context. Extending the TAM model to explore the antecedents, the authors find that the e-procurement quality dimensions of processing, usability, and professionalism impact the levels of individual employee e-procurement acceptance. Interestingly, the system-level dimensions (processing and usability) appear to play a greater role than the support dimensions (professionalism) in these cognitive mechanisms.

The findings indicate that the need for e-procurement training and on-going support may be lessened by initial effective design covering system navigation and system usability and by ensuring that an e-procurement system has expedient information and product flows between the buyer and supplier.

To the authors’ knowledge, this is the first study to explore the TAM and, more critically, its antecedents within an e-procurement context. It is also the first to empirically validate this extended model. Finally, by shifting the focus from the more typical organisational-level adoption to an individual employee acceptance unit of analysis, the authors provide a better understanding of how organisations can gain the most from investments in e-procurement and other similar e-supply chain management technologies.

Despite significant investment in e-procurement by many organisations, perceived failings in the quality of such technologies and of the support provided to use them – termed here e-procurement quality – continue to generate resistance from internal customers who must assimilate e-procurement into their daily routines. Hence, the purpose of this paper is to advance the understanding of e-procurement quality from an internal customer perspective and to develop, refine, and validate construct measures.

Research was undertaken in the UK and the Netherlands incorporating a literature review, a qualitative study with 58 interviews, a quantitative study with 274 survey respondents, and a replication study with 154 survey respondents.

Analysis reveals that e-procurement quality comprises five universally applicable dimensions: processing, content, usability, professionalism, and training. A sixth dimension, specification, appears to be applicable, but context specific.

The study represents one of the most extensive investigations of e-procurement quality to date and is the first to examine its underlying dimensional structure. The multi-item scales developed and validated using a mixed-methods process are suitable for theory building and testing, as well as providing useful diagnostic value to practitioners.

Contemporary supply chain relationships inherently rely on delegation of work between organizations and, thus, are subject to agency problems for which a wide range of governance mechanisms exist. This review of agency theory (AT), across four distinct fields, explains the connection between governance mechanisms and supply chain relationship types.

The study uses a systematic literature review (SLR) of articles using AT in a supply chain context from the operations and supply chain management, general management, marketing, and economics fields.

The authors categorize the governance mechanisms identified to create a typology of agency relationships in supply chains.

The developed typology provides parsimonious theory on different forms of supply chain agency relationships and takes a step towards a “supply chain-oriented agency theory” explaining and predicting relationship types and governance in supply chains. Furthermore, a future research agenda calls for more accurate measuring of agency costs, to examine residual gains alongside residual losses, to take a dual-sided perspective of agency relations and to adopt AT to examine more complex supply networks.

The review provides a menu of governance mechanisms and describes situations under which these mechanisms could be deployed to guide managers when developing their supply chain relationships.

The first review to combine and elaborate views from four major disciplines using AT as a lens to supply chain relationships. Expanding the traditional set of governance mechanisms provides academics and practitioners with a bigger “menu” of options to consider.

The purpose of this paper is to report on research into the impact of two sequential dimensions of strategic purchasing – purchasing recognition and purchasing involvement – on the development and deployment of dynamic capabilities. The authors also examine how such dynamic capabilities impact on both cost and innovation performance, and how their effects differ for service as opposed to manufacturing firms.

The authors test hypotheses using structural equation modeling of survey data from 309 manufacturing and service firms.

From a dynamic capability perspective, the analysis supports the positive relationships between purchasing recognition, purchasing involvement, and dynamic capability in the form of knowledge scanning. The authors also find support for the positive impact of knowledge scanning on both cost and innovation performance. From a contingency perspective, data supports hypothesized differences caused by industry, whereby service-based firms experience stronger positive linkages in our model than manufacturing-based firms. Finally, emerging from the data, the authors explore a re-enforcing effect from cost performance to purchasing involvement, something that is in line with the dynamic capabilities perspective but not typically addressed in operations management (OM) research.

The research offers a number of theoretical and managerial contributions, including being one of a relative few examples of empirical assessment of dynamic capability development and deployment; examining the enablers of dynamic capability in addition to the more commonly addressed performance effect; assessing the contingency effect of firm type for dynamic capabilities; and uncovering a return (re-enforcing) effect between performance and enablers of dynamic capabilities.

This paper presents the analysis from a study into the key lessons learned from e-procurement implementation across a range of UK public sector organisations. The literature relating to e-procurement implementation and operation is reviewed, identifying five main themes addressed by the current literature: impact on cost efficiency; the impact on the form and nature of supplier transaction; e-procurement system implementation; broader IT infrastructure issues; and the behavioural and relational impact of eprocurement. The research carried out was intended to explore the perceptions and reflections of both 'early' and 'late' adopters of e-procurement. Seven key lessons are drawn from the study and presented here. We conclude by proposing areas for further research, including the need for research into failed eprocurement projects.

The aim of this review and of the papers in this special issue is to critically examine different approaches to teaching operations management (OM) in order to provoke and stimulate educators within the discipline.

The papers within this special issue include empirical assessments of a problem‐based learning enterprise resource planning (ERP) simulation; a computer‐based learning tool for material requirements planning (MRP); a simulation of assembly operations; an operations strategy innovation game; an extension of the production dice game; an experiential teaching method in different class settings; and problem‐based assessment methods in OM. A variety of data are used to support these empirical studies, including survey, interview, and observational data.

The papers within the special issue support the argument that OM is well‐suited to more applied methods of teaching focusing on the application of subject knowledge to real‐life situations through a variety of techniques.

It is hoped that this review and the papers within this special issue act to stimulate educators to re‐evaluate their approaches to teaching OM and encourage them to consider adopting experiential teaching methods, business simulations, role‐plays, group exercises, live cases, and virtual learning environments, instead of, or in addition to, the more conventional lectures that typically dominate many OM modules around the world.

A special issue on teaching OM appears timely given the significant changes to both the university landscape and to the nature of the discipline that we have witnessed over the last quarter of a century.

This paper aims to examine the preferences of students towards different teaching methods and the perceived effectiveness of experiential teaching methods in different operations management (OM) modules.

Student perceptions of different teaching methods and various aspects of an experiential teaching method, in the form of a business simulation game, are examined using survey data from 274 respondents in four small post‐experience and two large pre‐experience OM modules.

The paper's analysis suggests that traditional and experiential teaching methods are both popular with OM students, whilst independent teaching methods are less well liked. Analysis also shows that students on both kinds of OM modules perceive most aspects of the experiential teaching method used in this study (The Operations Game) very positively.

This research study was confined to a particular type of experiential teaching method – a business simulation game. There is a need for further research to investigate the perceived effectiveness of other experiential teaching methods, such as role‐plays and live cases. Furthermore, the paper does not examine the use of experiential teaching methods that do not require the physical presence of students.

For OM educators, the paper clarifies how they might incorporate experiential teaching methods in different class settings. Whilst experiential teaching methods are typically used for small post‐experience modules, these data indicate that the method can also be used on larger pre‐experience modules with great success. The paper also notes a number of challenges involved in using experiential teaching methods on both kinds of module.

This is the first known study to directly examine the perceived effectiveness of an experiential teaching method in both small post‐experience and larger pre‐experience OM modules.

Whilst e‐procurement has significant potential to reduce the purchasing costs of an organisation, the realisation of these savings requires user compliance. The purpose of this paper is to examine the extent to which user‐perceived e‐procurement quality (EPQ) (operationalised through the dimensions of professionalism, processing, training, specification, content, and usability) influences both system and contract compliance.

User perceptions of EPQ were examined in four UK organisations using survey data from 274 respondents.

Strong evidence was found of a positive relationship between user‐perceived EPQ and both system and contract compliance. System compliance was most strongly influenced by professionalism and content dimensions, whilst contract compliance was most strongly influenced by processing, specification, and content dimensions.

Data were collected from e‐procurement users in four organisations, which may limit the extent to which findings can be generalised.

User perceptions of e‐procurement provision significantly influence system and contract adoption. Practitioners should pay attention to management of different dimensions of perceived quality as they may have different effects on both contract and system compliance.

This paper is the first to empirically assess the relationship between user‐perceived EPQ and compliance. Its findings challenge the assumption that the monopolistic dynamics common within internal services, such as e‐procurement provision, are sufficient to ensure compliance. Dissatisfied individuals invariably find ways to circumvent mandatory systems and contracts.

The paper examines the moderating role of a purchasing function's absorptive capacity (AC) on the relationship between the use of electronic purchasing tools and category level purchasing performance. The authors argue that an e‐purchasing tool may not in itself positively influence performance unless combined with AC as a human interface to maximise its information and transactional improvement potential.

Survey data collected from 297 procurement executives of large companies in ten countries are analysed using confirmatory factor analysis (CFA) and hierarchical moderated regression.

The results demonstrate few significant direct effects of e‐purchasing tools on category performance. All performance measures studied are enhanced when dimensions of AC and their interactions with the e‐purchasing tools are added. Specifically, buyer competence, manager competence and communications climate have performance‐enhancing effects. In some cases, AC on its own appears to increase performance more than e‐tools.

This paper is the first to study the moderating effects of AC on the relationship between e‐purchasing tool usage and category performance. Its findings support the view that simply implementing technology does not lead to performance improvements, but that a human interface is required to maximise the information and transactional improvement potential of e‐purchasing tools.

This paper aims to build upon the debate in the service quality literature regarding both the theoretical and practical effectiveness of expectations data in the measurement of internal service quality (ISQ). Gap‐based and perceptions‐only approaches to measuring ISQ are tested and their respective benefits and limitations evaluated.

The internal service context used in this study is the provision of e‐procurement software, training, and user support in four organisations. The two approaches are evaluated in terms of reliability and validity, as well as pragmatic aspects of survey administration.

The various tests carried out indicate that both the gap‐measure and perceptions‐only measure are reliable and valid, the latter being the marginally higher performer. Both approaches were found to have benefits and limitations, and so the empirical study, combined with contributions from the literature, generates some understanding of the internal service context in which the two approaches might be appropriate.

The survey was based on an internal e‐procurement service; as such, the variables and dimensions selected to measure ISQ in this context inevitably limit the scope of the research.

For operations managers, the paper clarifies the basis on which they might choose between the two approaches to ISQ measurement.

This study is the first to directly test and compare the relative merits of these two approaches to ISQ measurement. The paper also offers insights as to the operational contexts in which each approach might be appropriate.
