Managing Large-scale IT Projects: The Case of National Air Traffic Services' New En Route Centre at Swanwick

UK experience with implementation of high-profile IT projects has been rather unhappy, with projects tending to be severely delayed, to operate poorly and to be prone to escalating costs. There is therefore a need to understand better and to improve the management of such investments. This paper adopts a synthetic approach to analysing large-scale IT projects, drawing upon research on managing inflexible technology, project management and information technology implementation. The paper combines findings from these literatures to produce a detailed set of factors that are known to adversely affect ambitious software and other large-scale development projects. It employs a case study of software development at National Air Traffic Services' NERC project at Swanwick potentially to illustrate these. The paper finds that experience at Swanwick does indeed mirror many of the pitfalls predicted but also that the synthesis of approaches attempted enhances our understanding of the difficulties involved in managing large-scale IT projects perhaps rather better than univocal approaches.     

The four faces of the Hispanic consumer: An acculturation-based segmentation

This article develops and tests a segmentation scheme for the U.S. Hispanic market based on the extent and nature of acculturation. Acculturation is conceptualized as driven by language preferences and two dimensions of cultural identification, Hispanic and American. Structural equation modeling develops and assesses the proposed scales, and a latent class clustering procedure (latent discriminant analysis) tests propositions on a sample of 403 U.S. Hispanics. Consistent with theory, four clusters of U.S. Hispanics emerge: retainers, biculturals, assimilators, and non-identifiers that vary according to language preference and cultural identification.     

An Economic Model of Faculty Grading Practices

The statistical evidence examined by the author indicates that faculty members with relatively few students tend to assign higher grades than would be expected otherwise. In evaluating student achievement and faculty performance, therefore, one must not only be aware of this association, but also be able to assess its significance.     

Exact solutions for ruin probability in the presence of an absorbing upper barrier

Abstract

An explicit solution for the probability of ruin in the presence of an absorbing upper barrier was developed by Segerdahl (1970) for the particular case in which both the interoccurrence times between successive claims and the single claim amounts follow an exponential distribution with unit mean. In this paper we show that his method of solution may be extended to produce explicit solutions for two more general types of single claim amount distribution. These are the gamma distribution, denoted γ(a), where a is an integer, and the mixed exponential distribution. Comparisons are drawn between this approach when the upper barrier tends to infinity, and the classical solution for ruin probability in these particular cases given in Cramér (1955).     

PROPERTY MARKET AND THE MACROECONOMY OF MAINLAND CHINA: A CROSS REGION STUDY

Abstract.  This paper studies the nexus between the property market and macroeconomy of China in 1998–2004, using panel data models covering 31 provinces and major cities. The estimates suggest three main conclusions. First, there seemed to be a two-way linkage between property prices and GDP growth. Second, bank credit expansion did not seem to play an 'accelerating' role in property price inflation, although the latter is found to have contributed to bank credit increases in recent years. Third, property price growth may have deviated from fundamentals in coastal areas, as evidenced by a negative relationship between housing and rental prices.     

The Causal Effect of Education on Wages Revisited*

This study estimates the return to education in Britain using two instrumental variable (IV) estimators: one exploits variation in schooling associated with early smoking, the other uses the raising of the school leaving age; both affect a sizeable proportion of the sample. Early smoking is found to be a strong and valid IV and unlike previous IV strategies uses variations in education at numerous points across the distributions of (i) education, and (ii) ability. Thus whilst still a ‘local average treatment effect’ the estimate is closer to the average effect of additional education, akin to least squares but corrected for endogeneity.     

Concentration history and market power in US manufacturing industries

For a 1963–1992 panel of US manufacturing industries, the relationship between seller concentration and both price-cost margins (PCMs) and prices is investigated for industries divided by whether concentration has recently increased or decreased. Regressions of PCM in levels and first differences, and price equations in first differences, establish that the positive effect of concentration on prices and profits is always weaker in industries where concentration has recently increased and always stronger in industries where concentration has recently decreased. These results are attributed to the different endogeneity biases in the two samples. Increasing concentration industries are more likely the ones where leading firms have lowered prices to gain share, while decreasing concentration industries are more likely the ones where smaller firms have lowered concentration by lowering prices. An additional conclusion is that the cost-reducing effects of changes in concentration are greater for increasing concentration industries, meaning that increasing concentration industries have lower price increases compared to decreasing concentration industries.     

The paradox of a marketing planning capability

Strategy scholars have long debated the value of formal planning, and research has offered inconsistent support for planning to enhance firm performance. Given these mixed empirical effects, we draw from the resource-based view of the firm to illustrate a paradox firms may face. In particular, a strong marketing planning capability may not only reduce the incidence of postplan improvisation but also contain inherent process rigidity. Since both of these can also increase performance, results illustrate a performance paradox in marketing planning. Rebecca J.
