W 1. IntroductionThe transformation of change economies from a manufacturing base to a good orientation is a continuing phenomenon. The trend is readily sheer in the United States where, by virtually all accounts, over 80% of private sector consumption is engaged in some sort of mathematical process work (Karmarkar, 2004). Despite this, observers of research in operations commission (OM) have long been critical of the ? days for not transitioning in a similar manner. angio tensin converting enzyme study by Pannirselvam et al. (1999) reviewed 1,754 articles surrounded by 1992 and 1997 in seven key OM journals and reported only 53 (2. 7%) addressed helping-related lines.Roth and Menor (2003) also voiced concern virtually a paucity of research in presenting a military divine assistant operations management (SOM) research agenda for the future. Regardless of the exact ? gures, there is clearly spacious potential and need for research in the dish up operations arena. Recent developments within the discipline are encouraging. For example, Production and Operations focusing (POM) and the Production and Operations solicitude Society (POMS) have taken several(prenominal) steps to facilitate research in gain operations. First, the journal recently published three rivet curves on 780 overhaul operations.Second, POMS created a society subdivision, the College of expediency Operations, that has hosted several national and international meetings. Fi nally, the journal presently has an autonomous editorial department dedicated to military swear out operations. Other initiatives to promote the military service operations management ? eld include the establishment of IBMs Service Science, way, and Engineering initiative (Spohrer et al. , 2007) and the appoint for Operations question and focusing Science Section on Service Science. To a tumescent extent, the service operations ? eld has long been considered to occupy a niche within operations management.If service operations management researchers are to establish themselves ? rmly within the OM friendship, it is our contention that their theoretical contributions to leading academic journals must be more astray recognized and their relevance to practice acknowledged. As a part of the effort to encourage this progress, the purpose of this line of descent is twofold (1) to demonstrate that published work in the key operations journals is indeed showing an up(a) trend a nd (2) to facilitate research of individual scholars by localizeing the individuals and institutions that have contributed most to the ? ld of service operations. Smith, Karwan, and Markland Growth of query in Service Operations Management Production and Operations Management 16(6), pp. 780 790, 2007 Production and Operations Management Society 781 2. Methodology and Results Although some(prenominal) more complex mechanisms exist to measure contribution, we relied on a guileless commence to assess contributions by individuals and institutions. We considered four issues (1) the time frame for the review, (2) the journals to be included, (3) the metric for productivity, and (4) the means to identify the articles to be included.First, we selected a 17-year time frame beginning with 1990 and running through 2006 because we believed that this interval would provide a comprehensive picture of the service operations ? eld as it has developed, as well as an fortune to detect any over all trends. Next, we limited our assessment to the outlets identi? ed by the University of Texas at Dallas as the postmortem journals in operations management (see http//citm. utdallas. edu/ utdrankings/).These include 3 journals dedicated to OM, the journal of Operations Management (JOM), Manufacturing and Service Operations Management (MSOM), and POM, and two multidisciplinary journals, Management Science (MS) and Operations explore (OR). Third, we assessed scholarly productivity by counting the number of research articles attributable to both individuals and their academic institutions, assigning a weight of 1/n to an author and his or her institution if an article had dual (n) authors. The ? al issue to settle down was what constituted a SOM article. We ? rst eliminated any article or research note that centered on agri nuance, mining, or manufacturing. Then, two authors served as independent judges to determine whether an article employed an operations focus spot addressin g a service-speci? c job or situation. In cases where there was disTable 1 form 1990 1991 1992 1993 1994 1995 1996 1997 1998 1999 2000 2001 2002 2003 2004 2005 2006 Totals Service % organisation between the two raters, the third author made the ? al decision. Consequently, an article was excluded if it developed a generic wine operations poseur or involved an operations topic that was discussed in a general way and was applicable in either a manufacturing or a service environment. When an article made speci? c reference to service considerations and elaborated on them, it was included. To clarify this point, consider the case of an article investigating an stock certificate-positioning insurance policy indemnity between a manufacturer and a series of retailers.The article would be included as pertaining to service operations if it took the perspective of the retail operation but would be excluded if it took the manufacturing viewpoint. Using this methodology, we identi? ed 463 distinct service operations articles (see the Appendix for a complete list) and recorded information on the author(s) and author af? liation(s) at the time of humanityation. The numerical summary of articles is shown in Table 1, with each journals percent of service operations articles.Over the 17-year period JOM, MSOM, and POM all exceeded 15% of service articles with respect to the total number of articles published, with OR and MS publishing somewhat smaller percentages. Additionally, there is an upward trend in the total number of service articles appearing in all ? ve journals, with a marked increase in the past 3 age (see Figure 1). With regard to JOM and POM, part of this move is attributable to the publication of special issues, which is a positive development because it demonstrates a heightened emphasis originating at the editorial level.The total number of individuals appearing in the sample pond was 799.

Many of these authors and institutions are known to approach the ? eld from normative or prescriptive perspectives and others from more empirical or descriptive perspectives.In fact, Gupta, Verma, and Victorino (2006) recently noted that much of the growth in service research has come from studies that completely or partially employed empirical research methodologies. This increased emphasis on empirical studies bodes well for the new and growing ? eld.

Concluding Comments A variety of forces appear to be stimulating a longexpected increase in research emphasis on service operations management. Because service organizations and issues increasingly drop the global economy, a greater emphasis on SOM research seems important and inevitable. With operations management journals and related professional societies simultaneously providing visibility for researchers and their efforts, it is likely that we will move forward toward a clearer and more sturdy SOM research paradigm.Acknowledgments We thank the anonymous reviewers and the editorial team for their insightful comments on earlier drafts of this paper.
