Social capital as a facilitator of successful buyer-supplier performance management

Performance management in supply chains is an increasingly important, rapidly developing but challenging area. It may benefit from sufficient levels of social capital, such as frequent interactions between buyers and suppliers. However, social capital has not yet been studied as a facilitator of performance management. To bridge this knowledge gap, we examine buyer-supplier performance management and social relationship characteristics as perceived by suppliers. We analyze empirical data gathered through a survey of 482 suppliers by employing PLS-SEM and PLS-MGA. The findings elaborate on the role of cognitive, relational, and structural capital in performance management activities within a buyer-supplier relationship. Moreover, the results demonstrate how a supplier's positive perception, in the form of preferred customer status, can be facilitated through performance management activities. The findings reveal that there is a difference in the role of structural and relational capital between key and non-key supplier groups in performance management activities. We conclude that successful performance management in buyer-supplier relationships requires more than simply a system for sharing information. The mature use of performance measurement is also essential, with cognitive capital being especially beneficial in this endeavor.     

Examining transformational leadership,job satisfaction,organizational commitment and organizational trust in Turkish hospitals: public servants versus private sector employees

Leadership, job satisfaction, organizational commitment and trust have become important processes for healthcare management in recent years. One of the contemporary human resource management functions in the organizations involves engaging in leadership development, improving organizational trust and organizational commitment and increasing job satisfaction. Considering the rapidly changing healthcare technology and higher levels of occupational complexity, healthcare organizations are increasingly in need of engaging in leadership development in any given area of expertise to address ever-changing nature of the industry and the delivery of quality of care while remaining cost-effective and competitive. This paper investigates the perceptions of both public servants and private sector employees (outsourcing) on transformational leadership, organizational commitment, organizational trust and job satisfaction in Turkish healthcare industry. Additionally, the paper analyzes the predictability of organizational commitment based on employee – both public servants (physicians, nurses, administrative personnel and other healthcare professionals) and private sector employees (outsourcing) (auxiliary services such as administrative assistants, security personnel, kitchen, laundry and housekeeping employees) – perceptions of transformational leadership, job satisfaction and organizational trust. Using a survey instrument with items adopted from the transformational leadership inventory (TLI) [Podsakoff, P. M., MacKenzie, S. B., Moorman, R. H., & Fetter, R. (1990). Transformational leader behaviors and their effects on followers' trust in leader, satisfaction, and organizational citizenship behaviors. Leadership Quarterly, 1, 107–142], the organizational commitment questionnaire [Meyer, J. P., & Allen, N. J. (1997). Commitment in the workplace: Theory, research, and application. Thousand Oaks, CA: Sage], the organizational trust inventory (OTI) [Cummings, L. L., & Bromiley, P. (1996). The occupational trust inventory (OTI): Development and validation. In R. Kramer & T. Tyler (Eds.), Trust in organizations: Frontiers of Theory and Research (pp. 302–330). Thousand Oaks, CA: Sage] and job satisfaction survey (JSS) [Spector, P. E. (1985). Measurement of human service staff satisfaction: Development of the job satisfaction survey. American Journal of Community Psychology, 13, 693–731], this quantitative study was conducted among 2108 healthcare employees (public servants and private employees) in two large government hospitals in Turkey. The study findings indicate a significant difference between the public servants and private sector employees in terms of their perceptions on two dimensions of transformational leadership (being an appropriate model, providing individualized support), overall transformational leadership and one dimension of job satisfaction (communication). The two dimensions of job satisfaction – operating procedures and communication – as well as organizational trust were the significant predictors of organizational commitment of public servants, whereas the two dimensions of leadership – individualized support and fostering the acceptance – as well as the two dimensions of job satisfaction – promotion and contingent rewards – and organizational trust were the significant regressors of organizational commitment of private sector employees. In addition, there is a significant difference between the predictors of the dimensions of organizational commitment (transformational leadership, job satisfaction and organizational trust) in terms of public servants versus private sector employees. Finally, organizational trust has a significant effect on overall organizational commitment as well as its three dimensions for public servants and private employees.     

A multi-level examination of quality-focused human resource practices and firm performance: evidence from the US healthcare industry

In today's business world, the role of quality has become ever more significant for organizations to compete in a global marketplace. Based on the quality management theory, this study empirically examines the relationship between quality-focused human resource practices (QHRP) and organizational performance outcomes. Data from 69 healthcare organizations indicate a strong support for this relationship. A Human Resource (HR) system focused on quality management was directly related to multiple dimensions of organizational performance outcomes (i.e., intangible – employee satisfaction and customer satisfaction – and tangible – profit). Specifically, two measures of QHRP, knowledge management and strategic management, were found to be positively related to the financial performance of firms implementing quality management. Process management is found to be negatively related to employee satisfaction. General Human Resources were positively related to both employee and customer satisfaction. Employee focus of the firms is also positively related to employee satisfaction. In addition, employee satisfaction is also related to both customer satisfaction and financial performance while customer satisfaction is found to be positively related to employee satisfaction. The findings indicate a generally strong positive relationship with the organizational performance outcomes. The results of this study are particularly important in showing HR's contribution to the organization's bottom line.     

Six Sigma: Definition and underlying theory

Six Sigma has been gaining momentum in industry; however, academics have conducted little research on this emerging phenomenon. Understanding Six Sigma first requires providing a conceptual definition and identifying an underlying theory. In this paper we use the grounded theory approach and the scant literature available to propose an initial definition and theory of Six Sigma. Our research argues that although the tools and techniques in Six Sigma are strikingly similar to prior approaches to quality management, it provides an organizational structure not previously seen. This emergent structure for quality management helps organizations more rigorously control process improvement activities, while at the same time creating a context that enables problem exploration between disparate organizational members. Although Six Sigma provides benefits over prior approaches to quality management, it also creates new challenges for researchers and practitioners.     

Exploring the efficacy of healthcare quality practices, employee commitment, and employee control

This exploratory study examines healthcare quality program practices, employee commitment and control initiatives, and perceived results by surveying the directors of hospital quality programs. U.S. hospitals are renowned to be among the highest in quality, but recent studies assert that the majority of error-related deaths per year are preventable. In response, healthcare organizations have adopted quality management programs. Employee commitment and control theories propose that employee initiatives are critical to patient safety. However, little research has focused on the efficacy of employee commitment and control initiatives for quality programs at healthcare organizations. This study examines the responses from Quality and Risk Directors of 372 U.S. hospitals. The results of structural equation modeling (SEM) demonstrate that perceived quantitative and qualitative quality program results are more highly related to employee commitment and control initiatives than they are related to quality practices.

Alignment mechanisms for supplier-initiated innovation: Results from the logistics service industry

In service outsourcing, buying organizations frequently experience shortcomings in supplier-initiated innovation. To address this problem, we develop a model that distinguishes two mechanisms for buyer-supplier alignment (i.e. relational and formal innovation alignment) and outlines how their effectiveness differs depending on the level of hierarchy in the relationship. Using data from the logistics service industry, it is shown that when the level of hierarchy is comparatively low, where buyers and suppliers interact participatively, both relational and formal innovation alignment are effective in fostering supplier-initiated innovation. Yet, as the relationship becomes more hierarchical and dominated by the buyer, the effect of relational innovation alignment diminishes and eventually turns negative, while the effect of formal innovation alignment is strengthened.     

The role of organizational cultures in information‐systems security management: A goal‐setting perspective

The aim of this research is to investigate the role of strong organizational cultures in setting information‐systems security goals. In doing so, we explore and discuss the concept of culture within three financial organizations with different social and organizational structures, and seek to demonstrate the importance of having a cohesive culture in efficiently setting information‐security goals. The relationship between goal setting, culture strength, and performance is also discussed, as there have been studies that indirectly indicate that such a relationship may exist. The contribution of this work to interpretive information‐systems research consists of its study of culture and goal setting in a security‐management context, and its grounding within an interpretive epistemology. In addition, this research promotes an interdisciplinary and interorganizational theory to foster dialogue that transcends industry‐specific contexts and explores different organizational practices that can improve leadership's role in human life.     

Performance management effectiveness: practices or context?

Although much research has focused on the technical or measurement issues involved in employee performance management, this study investigates the mutual influence of practices and context on performance management effectiveness. From a sample of 312 private and public sector organizations with 200 or more employees, the results indicate positive associations between practices – training and employee recognition – and performance management effectiveness. They further underscore the relevance of three contextual variables – culture, climate and the strategic integration of human resource management – as they are also related to more positive performance management outcomes. Implications for research and practice are discussed.     

Development and validation of a measurement instrument for studying supply chain management practices

It is widely argued that competition is no longer between organizations, but among supply chains. Effective supply chain management (SCM) has become a potentially valuable way of securing competitive advantage and improving organizational performance. This research conceptualizes, develops, and validates six dimensions of SCM practices (strategic supplier partnership, customer relationship, information sharing, information quality, internal lean practices, and postponement). Data for the study were collected from 196 organizations and the measurement scales were tested and validated using structural equation modeling. It is hoped that this study will provide a parsimonious measurement instrument to assess the performance of the overall supply chain.     

Multi‐Level Efficacy Evidence of a Combined Interprofessional Collaboration and Project Management Training Program for Healthcare Project Teams

Project work is essential for the improvement of healthcare organizations; yet, project management and collaboration in the project context are not taught to healthcare professionals. Three half‐day training workshops integrating project management and collaboration were designed and delivered to 14 interprofessional healthcare project teams. Multivariate measures were taken over the course of 36 weeks. Individual, team, and project‐level results showed high satisfaction and perceptions of utility; improved self‐efficacy for project‐specific task work and teamwork; increased goal clarity and coordination; and a significant impact on the functional performance of projects. This study provides initial benchmark measures regarding the pertinence of project management and interprofessional collaboration training for healthcare project teams.     

Understanding the dynamics of global supply chain sustainability initiatives: The role of institutional distance from the buyer's perspective

Research points to sustainable supply chain management as a core strategic goal for most global firms. However, managers continue to struggle with implementing successful sustainability initiatives both internally and throughout their globally dispersed supply chains. Using grounded theory, our findings uncover a potential explanation for how firms manage sustainability initiatives in the context of global supply chain management, from a buyer's perspective. Institutional theory of the firm is applied to help explain the challenges of developing and implementing global supply chain sustainability-related initiatives within buyer-supplier relationships. Analysis of the data from qualitative interviews show that institutional distance is an influential factor that produces mixed effects on the global buyer-supplier relationships in our sample in the context of buyer and supplier strategic orientation toward sustainability. The findings can help guide managers when approaching sustainability-related initiatives in the context of global supply chains. Theoretical and managerial implications are discussed as well as areas for future research.     

Impact of organizational and project factors on acceptance and usage of project management software and perceived project success

This study surveyed 497 participants to determine the factors that affect project professionals' acceptance of project management software and the perceived impact of software usage on their performance. The study finds that greater information quality and higher project complexity are the dominant factors explaining higher levels of system utilization, that greater system functionality and ease of use have a significant positive relationship with increased software usage, and that a strong positive relationship exists between higher usage of project management software and perceived project managers' improved performance. Inconsistent with prior research, more training was not found to be associated with project management software usage. The study explains more than 40% of the variation in project management software acceptance and adds project management software usage to project success factors by empirically confirming for the first time that project management software enhances project professionals' perceived performance and provides a positive impact on the results of their projects. The study provides practical implications for project professionals, their organizations, senior management, decision makers, software developers, and vendors. These findings support the call for further research that investigates the diffusion of information technologies in the project management field and their impact on project success and competitive position.     

ISO 9000 practices and financial performance: A technology coherence perspective

Attention to processes has increased, as thousands of organizations have adopted process-focused programs such as TQM and ISO 9000. Proponents of such programs stress the promise of improved efficiency and profitability. But research has not consistently borne out these prospects. Moreover, the expectation of universal benefits is not consistent with research highlighting the important role of firm-specific capabilities in sustaining competitive advantage. In this paper, we use longitudinal panel data on ISO 9000 practices for firms in the auto supplier industry to study two new issues related to the adoption of process management practices. First, we find that, as the majority of firms within an industry adopt ISO 9000, late adopters no longer gain financial benefits from these practices. Second, we explore how firms’ technological coherence moderates the performance advantages of ISO 9000 practices. We find that firms that have a very narrow or very broad technological focus have fewer opportunities for complementary interactions that arise from process management practices and thus benefit less than those with limited breadth in technologically related activities.

The benefits of global teams for international organizations: HR implications

Abstract

In this special issue we aim to advance the theoretical, conceptual and empirical knowledge about the relationship between global teams and human resource management in international organizations. We argue that although the prevalence of global teams in international organizations is rapidly rising, simultaneously affecting the management of firms on global, regional and local levels, the response of firms and scholars alike to such changes has been slower, especially in the area of IHRM. The HR function in organizations could play a vital role in understanding, managing and leveraging the benefits of global teams to ensure that they contribute positively to the performance of firms, organizational units, and people. We demonstrate that there is still a disconnect in this respect and we highlight several areas in which the increasing use of global teams may challenge our conventional understanding of IHRM issues, and at the same time offer solutions for improvement in international organizations. The selected articles in this special issue provide both theoretical and practitioner implications by highlighting the need to explore the relationship between global teams and IHRM more generally and fully, as well as the need for HR practitioners and IHRM scholars to focus more on the ‘human’ and less on the ‘resources’ aspect. We trust that readers of this issue will agree that the articles all offer novel insights into key issues that open new avenues for further research in this nascent yet promising area.     

How do lean management organizations behave regarding training and development?

This paper analyses the role of training and development in lean management organizations. The hypothesis is that organizations characterized by lean management have a distinctive profile in terms of training and development. Specifically, it is hypothesized that lean organizations have the following features to a higher extent than non-lean organizations:

? employee involvement in training and development

? use of work groups for quality, product development and task flexibility

? attribution of importance to training in quality, customer orientation and people management

? line management responsibility for training and development of the employees

? use of job enlargement

? information of employees about management decisions

? use of team briefings and quality circles.

The analysis shows that it is possible to identify a relationship between lean management and training and development, although the statistical results could have been more significant. It is also discussed in the paper to what extent country-specific variables dominate (or are dominated by) company-specific characteristics. The general finding is that company-specific impact seems to be stronger than country-specific variables.

In general, it can be said that the lean management pattern as a company-specific variable is characteristic for most countries analysed (although to a varying degree). It is, however, sometimes confounded by country-specific variables. For instance, Turkey does not follow the general pattern, and the hypothesis can be supported only in selected minor areas. Hence, in this case country-specific variables outweigh company-specific variables. In most other countries, this is not the case.     

The effects of IT-enabled supply chain process change on job and process outcomes: A longitudinal investigation

Prior research on information technology (IT)-enabled supply chain management (SCM) has primarily focused on macro-level issues (e.g., IT capabilities related to SCM, and SCM design and optimization) and outcomes (e.g., firm performance). There has been limited research that focuses on micro-level outcomes related to employees who actually execute SCM processes in organizations. These employee-level outcomes are important because successful implementation of SCM systems and processes hinges on SCM employees’ support and commitment. I develop and test a model positing that SCM employees’ perceptions of changes in their work process characteristics, i.e., process complexity and process rigidity, following a new SCM system implementation will influence their job outcomes, i.e., job performance, job satisfaction, job anxiety, and job security, and their perceptions of process outcomes, i.e., process performance and relationship quality. The model incorporates a holistic appraisal of the extent of change—change radicalness—as a mechanism between work process characteristics and outcomes. The model is supported in three studies conducted in the context of three different SCM system implementations (N = 278, 282, and 304, respectively). In particular, I found that individuals perceived a significant change in their work process characteristics following an SCM system implementation, and changes in work process characteristics had a significant impact on job and process outcomes. These findings contribute to the information systems and operations management literatures and their intersections by offering insights on challenges related to IT-enabled SCM innovation implementation in organizations.     

ORGANIZATIONAL CONTEXT AND THE INTERPRETATION OF STRATEGIC ISSUES: A NOTE ON CEOS’ INTERPRETATIONS OF FOREIGN INVESTMENT*

This paper explores the relationship between organizational context and the interpretation of strategic issues by examining the hypothesis that CEOs' interpretations of foreign investment in the USA are influenced by the organizational context in which they are embedded. Three aspects of organizational context - the global business experience of the firm; the firm's level of organizational inertia (as represented by firm age and size); and the resources available for responding - are examined as predictors of CEOs' perceptions of foreign investment as a threat or an opportunity. Analysis of data from 320 organizations, controlled by industry, shows that global business experience, firm size, and perceived capability are significant predictors of the perception of threat and opportunity. the discussion addresses the implications of these findings for future research on issue interpretation and organizational context.
