Expert systems in production management: An assessment

Over the last several years expert systems (ES) have gained almost sensational interest. Within business administration, production management might be one of the most fruitful application areas for ES. There already exist a number of interesting pilot systems, and reports of research projects are beginning to appear in the literature.The main goal of this study is to identify systematically those areas in production management where an ES approach might be most promising. This is important to both researchers and practitioners because it helps pinpoint where research and development resources would be best allocated.In this article the authors provide a taxonomy for production management activities. They then combine this taxonomy with a well-known list of eight “expert tasks” to provide what they call an “applications map” to guide the discussion.After discussing existing research efforts and potential production management applications of expert systems, the authors employ a Likert scoring procedure to quantify their subjective ratings as to problem importance, potential for improved solution, and ease of development, for expert systems development efforts in a given production management decision situation.One conclusion here is that the applicability of expert systems to production management appears to be broadly based. This is particularly true for what the authors have labeled as “technological” activities. An interesting finding is the apparent lack of applicability of expert systems to inventory management. The authors found no existing system or research proposals applying expert systems to inventory management. Finally, systems that combine technological with logistical knowledge seem to be a fertile (but difficult) application area for ES.     

Towards an holistic understanding of disruptions in Operations Management

The paper reviews the literature on maintenance management, integrates key dimensions of maintenance within a taxonomy of maintenance configurations, and explores the impact of differing configurations on contextual factors and operational performance. “Prevention”, “hard maintenance integration” and “soft maintenance integration” were identified as key maintenance variables. Data were collected from 253 Swedish manufacturing companies, and three distinct clusters were identified. “Proactive Maintainers” emphasized preventive maintenance policies. “IT Maintainers” relied on computerized and company-wide integrated information systems for maintenance. “Maintenance Laggers” emphasized all maintenance dimensions to lesser extent than the others. The importance of maintenance prevention and integration differ between contexts. There were subtle performance differences across identified configurations, but preventive and integrated maintenance were more important for companies seeking competitive process control and flexibility. There existed no group with any great emphasis on all three maintenance dimensions, but attaining truly high performance may require a rare mix of the three dimensions. This mix of variables could constitute a hypothesized “World Class Maintenance” group.     

The implementation of computer based systems

The difficulty of implementing planned change in an organization is legend. In the last 20 years the implementation of computer based models and systems in particular has received a significant amount of attention in the form of hundreds of conference presentations, published case studies, and research reports. Yet, system implementation failures are still prevalent. p]This paper surveys the implementation literature primarily in three fields: management information systems, operations research/management science, and production-inventory management. Common difficulties are identified and managerial proverbs, consultants' insights, statistically verified procedures, research conclusions. and other such documented wisdom for improving the chances of implementation are analyzed. p]A classification scheme is developed which divides this documented material into three diverse categories of pitfalls in implementation. These categories are then discussed from the perspective of providing managers with the information needed to analyze their own organization in terms of the likelihood of successfully implementing such computer based information systems as Material Requirements Planning (MRP).     

Knotting the action net, or organizing between organizations

This paper presents a study of a successful organizing process, namely the knotting together of different types of action by “translating” them into one another. The connections thus established were then stabilized to form a unit that can be designated as an “action net”. This instance of organizing occurred in the course of a project in the Swedish health care sector, with a view to establishing coordination between care units in three separate organizations. Different laws regulated their tasks, their operations were financed by different principals, and the everyday work of their members was undertaken at different point in time and in different places. Despite this, the participants in the studied project were able to establish a lasting net of connections that contributed, in the eyes of the environment, to an instance of “good care”. In this paper we examine in detail the creation of an action net, and offer a tentative theory of organizing in action nets.     

The economic system as an end or as a means, the socialization of consumption, and the future of socialism and capitalism

After the demise of “real” socialism, socialism can be salvaged as a social preference system oriented towards equality and social justice, to be implemented without systemic constraints in the organizational and institutional sense. At the same time there is a case for creating an institutional framework allowing different forms of economic organization, capitalist and non-capitalist, to compete on equal footing, in an evolutionary perspective. Another way for a spontaneous extension of the domain of socialism could derive from the socialization of consumption, if the consumption of public goods continues to make up a growing component of real consumption.     

The cultural significance of accounting in Japan

We have had a spate of works on “Japanese Management” in the world, but very few on “Japanese Accounting”. In this article it is made clear that the functioning of accounting is contingent on the culture in which the accounting systems are incorporated, and that in order to discuss this intermingling of accounting and culture a perspective elaborated in Scandinavia can be relevant despite the uniqueness of Japanese culture. For only non-rationalistic or “naturalistic” perspectives can provide a basis for understanding the cultural dynamics of Japanese organizations and Japanese society. Thus the roles of accounting in Japan go far beyond what has been discussed in accounting textbooks.     

A theory of the temporary organization

The idea of the firm as an eternal entity possibly came in with the era of industrialism. In any case, the practical consequences of this idea contrast sharply with many ideas about projects and temporary organizations. Mainstream organization theory is based upon the assumption that organizations are or should be permanent; theories on temporary organizational settings (e.g., projects) are much less prevalent. In this article, we address the need for a theory of temporary organizations, thus seeking to supplement traditional project management wisdom. We also suggest some components of such a theory by elaborating on certain ideas about projects. “Action”, as opposed to “decision”, is one such component which is central to a theory of the temporary organization. In some respects we are thus dealing with antipoles, in other respects with concepts similar to those in established mainstream organizational theory. The role of “time” in the firm is different as compared to its role in the temporary organization. The differences have several important implications and we are able to suggest a coherent outline of a theory which we believe could be useful and which also covers several important aspects of temporary organizations.     

The challenge of computer-integrated manufacturing

Recent years have seen major changes in the pattern of industrial production. Three forces have been particularly significant in driving industry along the road to advanced automated production; growing international competition, the example of Japan and the availability of new technology. Their combined effect is a trend towards advanced and integrated manufacturing systems.These changes require what are often radical adjustments in the philosophy of production management, away from traditional concerns with discrete operations and towards a total systems management approach.This paper examines some of the features of the challenge posed to production management by the technological changes embodied in the “factory of the future”.     

Microworlds and Simuworlds: Practice fields for the learning organization

Management is one of the few professions, the authors note, in which members have no formal “rehearsal space” for honing their skills. In response to this need, organizations such as The Center for Creative Leadership, MIT's Learning Center, and The Stern School of Business at New York University have created a brave new world of management simulations—“practice fields” for the learning organization. Some of these new games (“simuworlds”) use computer programs to replicate an entire industry and give participants an opportunity to play out one company's strategy in that setting. Other simulations (“microworlds”) engage participants in complex behavioral role playing, based on scenarios that typically develop within a company. Still other simulations combine both approaches. The authors take their point of departure from Peter Senge's definition of the “learning barriers” that develop in any organization: solving fragmented “problems” rather than dealing with systemic issues; overemphasis on competition at the expense of cooperation; and a failure to innovate until forced to do so. The new simulations, the authors argue, are particularly useful in helping managers learn how to overcome these barriers.     

A typology of de-coupling strategies in mixed services

A typology of a class of service systems is proposed. The typology links strategic operational objectives to the decision to de-couple work between the front and back offices of a service system. Four specific ideal types of a strategy/de-coupling mix are described; each of which has distinct operational, marketing and human resource ramifications. A type that has had significant representation in traditional literature is the “Cost Leader” type, where back-office activities are de-coupled from the front office for the purpose of lowering costs. Another traditional type representative of the craftsman legacy is the “Personal Service” type, which retains back-office tasks in the front office to pursue non-cost-oriented strategic goals. Theoretical and empirical evidence is also given for two non-traditional types: the “Kiosk” type, where all tasks remain in the front office to achieve lower costs, and the “Focused Professional” type, which de-couples front- and back-office activities to enable front-office workers to provide higher service, rather than to reduce costs. Empirically, retail bank lending systems are analyzed to support the typology.     

From quality to innovation: Evidence from two French Employer Surveys

In this article we investigate the impact of quality systems on innovation performance using the method of propensity matching. We use two French microeconomic surveys, the “Organizational Changes and Computerization” (COI 1997) and the “Community Innovation Survey” (CIS3 1998–2000). The first hypothesis indicating that quality (ISO 9000 certification) impacts positively on innovation is supported for certain areas of innovation performance. Furthermore, the second hypothesis states that different levels of quality differentially improve innovation performance. Results indicate that the innovation performance of firms with Top Quality Level is higher than that of firms with Medium Quality Level which is also higher than that of firms with Low Quality Level for certain areas of innovation. However, we found that the difference in innovation performance between firms with Medium and Low Quality Levels is not of a great magnitude. This study implies that in order to achieve a significant innovation performance improvement via quality systems, a very well-established quality system is needed within a firm.     

Stability in the inefficient use of forecasting systems: A case study in a supply chain company

Computer-based demand forecasting systems have been widely adopted in supply chain companies, but little research has studied how these systems are actually used in the forecasting process. We report the findings of a case study of demand forecasting in a pharmaceutical company over a 15-year period. At the start of the study, managers believed that they were making extensive use of their forecasting system that was marketed based on the accuracy of its advanced statistical methods. Yet most forecasts were obtained using the system’s facility for judgmentally overriding the automatic statistical forecasts. Carrying out the judgmental interventions involved considerable management effort as part of a sales & operations planning (S&OP) process, yet these often only served to reduce forecast accuracy. This study uses observations of the forecasting process, interviews with participants and data on the accuracy of forecasts to investigate why the managers continued to use non-normative forecasting practices for many years despite the potential economic benefits that could be achieved through change. The reasons for the longevity of these practices are examined both from the perspective of the individual forecaster and the organization as a whole.     

The use of simulation in system design: A case study using the precision location strike system

The purpose of the article is to illustrate the use of computer simulation study and modeling in the design of complex systems. When new systems are designed, decision-makers rely heavily upon judgment, intuition and experience. The method discussed is intended to enhance these executive attributes by providing a vehicle with which the decision-maker may be proactive before implementing the system rather than being solely reactive after implementation.The application of a method known as the “systems science paradigm” is discussed and illustrated using the U.S. Air Force's Precision Location Strike System. The problem was to design a logistical support structure for the Strike System. The three major options proposed were to locate repair and resupply structures at the point of equipment use in Europe, to have a mixed system, or to locate support at a base in the continental United States.The research employed the paradigm suggested to develop an experimental Q-GERT simulation model of the processes and structures envisioned. Data development for abstract systems is illustrated and methods to experiment with alternate structures are developed and discussed. The concept of multiechelon inventory and repair are addressed within the problem's context.A proposed design alternative resulted from application of the process. Methods, other than cost effectiveness, to evaluate the system are also suggested. Implementing the design process for ill-defined systems appears to be an effective method for dealing with such design problems.     

“100% EDI-connected suppliers” projects: An empirical investigation of success factors

Electronic Data Interchange (EDI) is becoming increasingly important, and new organizational forms based on EDI suppliers’ capabilities are emerging. Therefore, taking advantage of recent technological changes, especially the development of Web-based EDI systems, many big industrial buyers are seeking to get all their suppliers EDI-connected. Based on previous research on EDI adoption, we conducted a survey to study the opportunities of success of such a “100% EDI-connected suppliers” policy using data from the vehicle industry. Findings from our survey helped us to understand suppliers’ responses to such a policy and to provide recommendations to industrial buyers who are seeking to succeed in a “100% EDI-connected suppliers” project. This includes employing tailored communication strategies and selecting appropriate incentives that take into account different levels of suppliers’ EDI-capabilities and suppliers’ dependence.     

Behind clients’ doors: What hinders client firms from “professionally” dealing with consultancy?

Prior research has located the issue of “professional” conduct with consultancy predominantly within the relationship between the manager and the consultant. However, recent studies provide indications that dealing professionally with consultancy may fail because of goal divergences between the individual managers and the organization. The first aim of this article is to re-examine this assumption theoretically, by drawing on agency theory, and empirically, by focusing on a single case study. Through this approach certain attitudes exhibited by managers are identified, which hinder dealing with consultancy in a professional manner across the entire organization. This observation motivates the second aim of the article: since the managers’ attitudes deviate from the company's goals in dealings with consultancy, the adequacy of governance measures needs to be analyzed. Several researchers have observed that companies primarily use control-based measures, like central procurement rules or policies, to govern managers dealing with consultancy. However, these measures are not readily accepted by managers. In view of the above, this study investigates alternative measures, which are summarized as incentive-based measures.     

The impact of employee satisfaction on quality and profitability in high-contact service industries

The extant operations management literature has extensively investigated the associations among quality, customer satisfaction, and firm profitability. However, the influence of employee attributes on these performance dimensions has rarely been examined. In this study we investigate the impact of employee satisfaction on operational performance in high-contact service industries. Based on an empirical study of 206 service shops in Hong Kong, we examined the hypothesized relationships among employee satisfaction, service quality, customer satisfaction, and firm profitability. Using structural equations modeling, we found that employee satisfaction is significantly related to service quality and to customer satisfaction, while the latter in turn influences firm profitability. We also found that firm profitability has a moderate non-recursive effect on employee satisfaction, leading to a “satisfaction–quality–profit cycle”. Our empirical investigation suggests that employee satisfaction is an important consideration for operations managers to boost service quality and customer satisfaction. We provide empirical evidence that employee satisfaction plays a significant role in enhancing the operational performance of organizations in the high-contact service sector.     

Modelling leadership—Implicit leadership theories in Sweden

This paper investigates Swedish data on implicit leadership theories in comparison with data from 61 other nationalities, testing the identification of a Swedish leadership style in light of globalization and possible converging value-formation processes. Global questionnaire data from 17,310 (900 Swedish) middle-managers constitute the basis for our analyses, using both a within-country perspective and a between-country perspective. While acknowledging the presence of almost universally endorsed leadership attributes, such as being inspirational and visionary, “typical” Swedish leadership attributes are possible to identify. Thus we challenge the simplified version of global convergence regarding leadership ideals and management ideology. On a basis of this study, we conclude that the notion of a Swedish leadership style is still meaningful and valid as a device for a better understanding of leadership efforts and cross-cultural interaction.     

An IR perspective on collective bargaining

In examining collective bargaining, industrial relations (IR) emphasizes a number of things of interest to HR scholars. First, IR adopts a different level of analysis from HR — that of the economy and the broader society — in contrast to HR's primary focus on the employing organization. Second, IR has an understanding of workplace conflict that emphasizes its collective and inherent nature, complementing HR's focus on managing individual conflict for the good of the organization. Finally, IR addresses the value of collective bargaining in promoting democracy and correcting “labor problems” arising from competitive markets, even in situations in which there is excellent personnel management.     

Information systems outsourcing: Replicating an existing framework in a different cultural context

In order for any field of study to refine the promising concepts and weed out the weaker concepts it is necessary that researchers revisit earlier studies from time to time and evaluate their general applicability to new contexts. Replication is an important technique for researchers to embrace in order to achieve this goal. In this study, we test one of the frameworks of technology outsourcing developed in the West, by changing the cultural context. Following Kodak's historic outsourcing decision, technology outsourcing has assumed significant importance among researchers and practitioners. Most of the research in relation to technology outsourcing has been conducted in the Western culture (including the USA and the UK), so our goal in this study is to extend the understanding of technology outsourcing research conducted in the West to another culture-that of Korea, through replication.We focused on information systems (IS) outsourcing decision making as a case in point and found both similarities and dissimilarities in relation to the current understanding of the same. These similarities and differences in turn, reveal the distinctions between the Western and the Korean approaches toward achieving outsourcing success. The similarities are the partial preference for short-term contracts and contracting out to external vendors. However, the two cultures differed in their decision making in the way they pursue contractual completeness, whether in-house departments competes or not, design of contract to include partnership measures, criticality of tasks outsourced, familiarity with the outsourced task, postponing a few outsourcing decisions, and withholding a piece of a contract as bait. We also found “trust” and “task partitioning to gain advantage of varied expertise” to be important for achieving outsourcing success in the Korean organization. In addition, we observed that outsourcing success is achieved by maximizing reliability and relationship in the Korean context rather than by maximizing flexibility and control, as was observed in the Western context. We argue that this difference is a function of cultural diversity.     

Analysis and design of focused demand chains

The paper describes the evolution of focused demand chains over an extended period of time as a major UK lighting manufacturer has sought to remain an international player in a fast changing business environment. Analysis and design procedures make use of the concepts of Wickham Skinner and Marshall Fisher to answer the strategic questions “what facilities are required and how should they be laid out to enable the necessary focused demand chains?” and to answer the tactical question “which focused demand chain is appropriate for this product?” The case study then details how the company has been transformed from operating within a traditional supply chain to driving change via the engineering of four focused demand chains. The paper concludes with a comparison of operations enablers, customer choice, and business performance metrics covering the transition period culminating in the current focused demand chain scenario. By matching products to the appropriate value stream there is a consequential reduction in product development time of 75%; manufacturing costs reduction of up to 27%; and up to 95% reduction in delivery lead times.
