Inventory management: Is there a knock-on effect?

Over the last several years a number of independent empirical studies have shown that organizational performance is related to a portfolio of management techniques, clearly demonstrating that there is no single “silver bullet.” In fact, these studies indicate that performance is positively correlated with the number of techniques employed and the depth of their implementation. Operational outcomes in areas like product quality, on-time delivery and productivity, as well as market measures like margins and export sales are both positively related to the implementation of a variety of techniques. This paper explores the relationship between the use of effective inventory management practices (as reflected in inventory turnover) and the implementation of other manufacturing practices. The hypothesis is that effective inventory management practices have a positive knock-on effect on the implementation of other practices. Since organizational performance is related to the implementation of multiple practices, the knock-on effect should have a positive effect on performance as well. The results show that inventory turnover is significantly related to the implementation of other techniques and weakly related to an index of overall company performance. This suggests a positive knock-on effect, but that it takes more than inventory management to achieve high levels of performance. Having established the knock-on relationship adds more evidence to the notion that management excellence in one area begets management excellence in others.     

Strengthening B2B brands by signalling environmental sustainability and managing customer relationships

Resource depletion and environmental pollution concerns are forcing manufacturers to pay greater attention to environmental sustainability. This is especially so for business-to-business (B2B) manufacturing firms who intensively use natural resources in their operations and are blamed for observable impacts on the environment. Despite investments in environmental sustainability practices by B2B manufacturers, studies provide little explanation about the extent B2B manufacturers obtain a positive brand image and superior market performance through environmental sustainability. Furthermore, research has not identified organisational practices that strengthen the path from environmental sustainability to market performance. Drawing on signalling theory, the customer relationship management (CRM) literature, attitude theory, and data collected from B2B manufacturers and their customers, we show that environmental sustainability practices provide positive benefits to B2B manufacturers' brand image, which, in turn, impacts market performance. Further, effective CRM and working with business customers with positive environmental attitudes are essential boundary conditions that strengthen the path from environmental sustainability practices to market performance.     

Designing flexible work practices for job satisfaction: the relation between job characteristics and work disaggregation in different types of work arrangements

The literature on flexible work practices has not yet evaluated in detail how the characteristics of a job affect job satisfaction. This study makes a distinction between two types of flexible work practices according to their aims: the accommodation of employees’ personal lives (employment practice) and the operational reasons of a firm (work practice). Based on this distinction, we studied how the characteristics of a job, which reflect the use of ICT to support the spatial disaggregation of business processes, influence the relationship between the two types of flexible work practices and job satisfaction. We show, through a survey conducted on 987 workers, that the characteristics of a job that favour work disaggregation positively moderate the influence of flexible work as a work practice on job satisfaction, but they do not moderate the influence of flexible work as an employment practice. The implications for managers, workers and scholars are discussed.     

Manufacturers shift the inventory carrying function

This article examines channelwide inventory management, and determines if manufacturers, as channel leaders, do force their policies onto subordinate channel members. Specifically, the ability of manufacturers to use their power to push the high cost of carrying inventories off onto other channel members is considered.     

Price authority and information sharing with competing supply chains

We characterize the degree of price discretion that two competing manufacturers grant their retailers in a framework where demand is uncertain and privately observed by the retailers, while manufacturers only learn it probabilistically. In contrast with the consolidated vertical contracting literature, we assume that manufacturers cannot use monetary incentives to align the retailers’ incentives to pass on their unverifiable distribution costs to consumers. Our objective is to study how, in this context, an information-sharing agreement according to which manufacturers share their demand information affects prices, profits and consumer surplus. While equilibria with full price delegation never exist, regardless of whether manufacturers share information, partial delegation equilibria may exist with and without the exchange of information. These equilibria feature binding price caps (list prices) that prevent retailers from passing on their distribution costs to consumers, and are more likely to occur when manufacturers exchange demand information than when they do not share this information. Manufacturers profit from exchanging demand information when products are sufficiently differentiated, and retailers’ distribution costs are high enough. Yet, expected prices are unambiguously lower when manufacturers exchange demand information than when they don’t, making the information exchange beneficial to consumers.     

An empirical analysis of inventory turnover behaviour in Greek retail sector: 2000-2005

In this study we investigate the determinants of inventory turnover. The study is based on an econometric analysis of inventory behaviour using an inventory turnover model. The empirical implementation of the model was conducted on a sample of financial data for 566 Greek retail firms for the period 2000-2005. By employing panel data techniques it was found that inventory turnover ratio is negatively correlated with gross margin and positively correlated with capital intensity and a measure of sales surprise.Decomposing the variance into its components associated with year, firm and retail segment effects, we found that a substantial amount of inventory turns variability is due to segment-wise effects. Moreover, the inventory turnover reaction to different sales changes was also studied. It was estimated that changes in sales bring on bigger changes when firms operate in sales-declined region. These results are useful in identifying methods and applications to improve inventory performance among firms and over time.     

What's in it for me? Capital,value and co-creation practices

Marketing research is increasingly concerned with the practices through which service providers and their customers interact and how these practices influence value co-creation.Applying S-D logic and drawing on practice theory developed in sociology research in past decades, we propose a definition of value in terms of the coexistence of diverse forms of capital and currency variations. We then develop a conceptual model to explain value co-creation in terms of service provider–customer interaction practices (SPCI practices). We employ an extensive, qualitative study in the context of professional service firms. Our findings reveal three general categories of SPCI practices (access to capital, capital exploitation and capital attrition) that affect value co-creation. These insights move forward business-to-business marketing theory and practice, advancing our understanding of how service provider–customer interaction practices can be used to define value propositions and assess the types and amount of value that are co-created.     

Human Resources Practices as Predictors of Work-Family Outcomes and Employee Turnover

Drawing on a nonrandom sample of 557 dual-earner white-collar employees, this article explores the relationship between human resources practices and three outcomes of interest to firms and employees: work-family conflict, employees' control over managing work and family demands, and employees' turnover intentions. We analyze three types of human resources practices: work-family policies, human resources incentives designed to induce attachment to the firm, and the design of work. In a series of hierarchical regression equations, we find that work design characteristics explain the most variance in employees' control over managing work and family demands, whereas human resources incentives explain the most variance in work-family conflict and turnover intentions. We also find significant gender differences in each of the three models. Our results suggest that the most effective organizational responses to work-family conflict and to turnover are those that combine work-family policies with other human resources practices, including work redesign and commitment-enhancing incentives.     

Extending community management to industry-university-government organizations

There has been an emergence of collaborative research networks of industry-university-government relationships, or so-called Triple Helix (TH) organizations. Many TH organizations strive for research and innovation community management. In the innovation and knowledge management literature, community management offers open, participatory, and distributed innovation processes. How community management elements manifest, how they evolve, and what are related contingencies remain poorly understood, especially in the case of TH organizations. Our study examines how two TH organizations in Finland have adopted community management elements, how these elements have evolved, and the contingencies that have affected adoption and evolution. We report on the first 6 years of operations in two different TH organizations. Community-management elements have accommodated divergent interests in TH organizations, but they have also been subject to considerable degrees of conflict and tension. We extend the innovation community management literature by explicating community management elements in a TH context, we illustrate how TH organizations adopt and evolve these elements, and we identify two contingencies for community management elements in a TH context.     

Simulation optimization-based decision support tool for steel manufacturing

To buffer against increasing global competition and variability in the price of raw materials, steel manufacturers continuously strive to improve operations and lower costs. In this research, we employ a simulation optimization approach to develop a decision support tool to aid in strategic and operational decision-making. Specifically, we investigate work-in-process inventory levels and potential manufacturing process modifications to reduce utilization costs. A simulation model captures the complex nature of the system while an optimizer searches the solution space and sends trial solutions to the simulation for evaluation. Experimentation suggests that significant daily cost savings are possible by modifying current inventory practices and production process capabilities. Overall, the work demonstrates the ability of the solution approach to analyze complex industrial systems and identify potential improvements in a short time frame.     

Quantifying the benefits of breaking bulk in retail operations

We explore the benefits of ‘breaking bulk’ in retail operations. Here, breaking bulk refers to delivering single units from distribution centers to retail outlets rather than the multiple units bundled together by manufacturers termed ‘case-packs’. The focus is largely on the benefits to space management at the retail level, rather than the more obvious reduction in inventory costs. Using data from the grocery industry, results indicate that retail unit profitability can be increased substantially by breaking bulk—but only if current inventory replenishment practices are changed. In essence, breaking bulk allows for either higher product variety within a store or identical variety in smaller stores. This work seeks to quantify the order of magnitude of that benefit.     

Skills, Flexible Manufacturing Technology, and Work Organization

This study employs a national survey of over 3000 U.S. manufacturing establishments to explore associations between worker skill requirements and use of production and telecommunications technologies, work organization, and other management practices. Ordered probit equations show an empirical link between increases in each of six types of skill requirements, as reported by plant managers, and the use of flexible technologies and work organization practices. Technology use is most strongly linked to computer skill requirements. Work organization practices were strongly associated with problem-solving and interpersonal skill increases, suggesting that new work organization practices are broadening the set of skills sought by manufacturers. Traditional academic skills (e.g., math and reading) also were linked to the use of flexible technologies and work organization practices, but increases in these skill requirements were reported less frequently than were requirements for computer, interpersonal, and problem-solving skills.     

Using System Dynamics to assess the impact of RFID technology on retail operations

The application of item-level radio frequency identification (RFID) technology in retail supply chains creates cost savings and promises large potential benefits from revenue growth. However, the economic assessment of the impact on improved store operations, labor utilization, and increased sales is still not fully explored. We propose to use System Dynamics as a structural modeling and simulation approach to integrate conventional return on investment evaluations. Building on previous research about RFID technology in retail supply chains, we developed a model based on the case exploration of a leading Italian apparel retailer. Simulations show that RFID implementations are profitable whenever they contribute to increase sales, especially when a fashion retailer is focused on clerk-assisted sales strategies. Sales growth results from the dynamic and integrated impacts of RFID technology on better inventory control, faster inventory turnover, and longer time available for store personnel to assist consumers as an effect of more efficient backroom operations.     

The roles of stakeholder support and procedure-oriented management on asset recovery

As the management of returned products is fast becoming a business trend caused by pressure for compliance, asset recovery is increasingly viewed as a fertile area for firms to reduce cost and improve quality. Environmental management is a viable approach for Chinese manufacturers to respond to the escalating international quest for conserving the environment, to tackle the problem of rising raw material costs, and to improve product quality by analyzing returned products. To reach the goals of cost reduction and product quality improvement, manufacturers need to understand how asset recovery can be leveraged through procedure-based practices and stakeholder support to enhance performance. Product type, characterized by different levels of demand uncertainty and time-to-market, may affect the outcomes of asset recovery adoption and should also be taken into account. Drawing on the environmental management and business logistics literature, we provide empirical insights on asset recovery adoption using survey data collected from export-oriented Chinese manufacturers. We find that asset recovery and stakeholder support are complementary in strengthening manufacturers' financial performance regardless of product type. In addition, the performance impact of asset recovery can be substantial when manufacturers' environmental management practices are less procedural, allowing flexibility in the logistics management of product flows.     

Lean Launch: Managing Product Introduction Risk Through Response-Based Logistics

New product launch research has identified four strategic issues that involve activities essential to introduce a new product to its target market. The sum of these decisions is critical to new product success. Substantial research has focused on decisions guiding the proper product, price, and promotion mix to favorably impact market goals. Considerably less research has centered on determining how place capabilities such as logistics and supply chain relationships impact launch performance. Logistics and supply chain collaboration—the processes involved in planning, implementing, and controlling the efficient, effective flow and storage of goods, services, and related information from the point of origin to point of consumption for the purpose of conforming to customer requirements—can greatly reduce risk associated with new product launch. They combine to provide a structure to facilitate rapid response to developing demand by location and intensity. In this article, an effort is made to fill the gap in extant knowledge regarding new product launch strategies by reviewing relevant literature and comparing traditional launch strategies based on anticipatory demand forecasts with alternative lean launch strategies based on the principles of response-based logistics. The result is a lean launch model for continued empirical testing and managerial review. The article contrasts traditional logistics support of new product launch with an emerging logic called lean launch strategy. The traditional launch strategy is forecast driven and is based on anticipatory logistics (push). The lean launch strategy is formulated on principles of postponement and is based on response-based logistics (pull) and supply chain management. Response-based logistics systems provide flexibility that enables better management of inventory levels. Improved replenishment times and in-stock availability of products from a centralized inventory allows managers to rapidly react to actual demand. Lean launch enhances successful introduction by allowing greater flexibility in product variant selection while minimizing out-of-stock potential. Lean launch also can cut losses in product launch failures by reducing launch inventory exposure. Finally, lean launch can improve chances of new product success by helping limited volume technical successes achieve profitability.     

Manufacturing Plants' Use of Temporary Workers: An Analysis Using Census Microdata

Using plant‐level data from the plant capacity utilization survey, we explore how manufacturing plants' use of temporary workers is associated with the nature of their output fluctuations and other plant characteristics. We find that plants tend to use temporary workers when their output is expected to fall; this may indicate that firms use temporary workers to reduce costs associated with dismissing permanent employees. In addition, we find that plants whose future output levels are subject to greater uncertainty tend to use more temporary workers. We also examine the effects of wage and benefit levels for permanent workers, unionization rates, turnover rates, seasonal factors, and plant size and age on the use of temporary workers; based on our results, we discuss various views of why firms use temporary workers.     

Produce growers’ cost of complying with the Food Safety Modernization Act

Small and medium size growers using both conventional and sustainable farming practices have expressed concern that compliance with the Produce Rule implementing the Food Safety Modernization Act will be prohibitively costly. We use data from an original national survey of fruit and vegetable growers to examine that contention. In particular, we analyze how expenditures on food safety practices required by the Produce Rule vary with farm size using a double hurdle model to control for selectivity in both using food safety practices and reporting expenditures. We find that expenditures per acre decrease with farm size. We also find some evidence that growers using sustainable farming practices spend more than conventional growers on many food safety practices. We use our estimates to quantify how the cost burden of compliance varies with farm size. We then explore the policy implications of exemptions to the Rule by simulating how more stringent exemption thresholds for farm revenue and share of direct sales might affect the cost burden of each food safety practice on farms at the threshold.     

The many shades of ‘openness’: an application of item response theory to open innovation research

This study addresses one of the most basic research questions investigated in the Open Innovation (OI) literature: how open are firms? This question has remained partially unanswered given the challenges encountered by empirical research in assessing the relevance of specific OI practices within the OI model, as well as the types of activities perceived by managers as OI benefits or concerns. To provide an answer to this question, we suggest a framework using Item Response Theory to improve over current measures of firms' openness and test it on a sample of 383 technology‐based SMEs. Our theoretical model conceives openness as an instance of how firms make decisions regarding the adoption of different OI practices based on their evaluation of OI benefits and concerns. Focusing on the relationship between firm‐level differences in terms of openness and the types of OI practices adopted by these firms, we show that significantly different levels of ‘OI maturity’ are required to broaden the scope of external partnerships and to shift from non‐pecuniary OI modes (relation‐based approaches) toward pecuniary (transaction‐based) practices. Our results have relevant implications for the OI literature and provide new managerial insight into OI adoption.     

A Balancing Act: Work–Life Balance and Multiple Stakeholder Outcomes in Hospitals

This article examines the direct and indirect effects of work–life balance (WLB) practices on multiple stakeholder outcomes in hospitals. The authors examine the direct and indirect effects of WLB practices in 173 hospitals in the United Kingdom on organizational, patient care and employee outcomes. The article proposes a model in which the effects of WLB practices on patient care outcomes and financial performance are mediated by employee turnover intentions. The authors provide strong support for the potential vested in WLB practices in the healthcare setting. Results indicate that greater use of WLB practices enhances outcomes for hospitals, their employees and the patients they care for.     

Why Are Quit Rates Lower Among Defense Contractors?

This paper presents empirical evidence of lower quit rates at small manufacturers with defense contracts and examines whether this is associated with differences in their human resource policies and organizational practices and strategies. We take advantage of an original data set to compare labor quits, workforce skills, and occupational structure between defense‐contracting and noncontracting small manufacturers in eastern Pennsylvania. We find that the remarkably large defense contractor advantage in quit rates—7 percentage points—is almost totally explained by differences in skills, operational strategies, and workforce management and training practices, suggesting a mediation effect through these HR practices. Defense‐contracting status emerges as an important overlooked variable in HRM studies.
