Business strategies can be clustered in three different and mutually exclusive categories: customer intimacy, operational excellence, and product leadership and innovation. This paper links these strategies to three key forces in the “IT driver model”: availability, total cost of ownership, and adaptability. Application of the model reveals four areas in need of management attention: (1) incomp...

Even within the financial crisis Global Sourcing is gaining more and more importance. Although a lot of European companies have already a long experience with international supply markets, uncertainties about the consequences and the costs related to a specific international supplier selection still remain. The Total Cost of Ownership concept is an interesting approach in order to cope with thi...

This paper generalizes the Myers and Majluf (1984) model by introducing an agency cost structure based on private benefits of control. This new model predicts that many corporate finance variables each have opposing effects on underand overinvestment. Private benefits exacerbate overinvestment but, interestingly, a small amount of private benefits can enhance firm value by alleviating underinve...

Technical support contributes 17% of the total cost of ownership of today’s desktop PCs [20]. An important element of technical support is troubleshooting misconfigured applications. Misconfiguration troubleshooting is particularly challenging, because configuration information is shared and altered by multiple applications. In this paper, we present a novel troubleshooting algorithm, PeerPress...

this paper addresses the mixed integer reliability redundancy allocation problems to determine simultaneous allocation of optimal reliability and redundancy level of components based on three objective goals. system engineering principles suggest that the best design is the design that maximizes the system operational effectiveness and at the same time minimizes the total cost of ownership (tco...

With increasing expenses for future HPC centers, the need to look at their productivity, defined as amount of science per total cost of ownership (TCO), grows. This includes development costs which arise from development effort spent to parallelize, tune or port an application to a certain architecture. Development effort estimation is popular in software engineering, but cannot be applied dire...

Currently three European satellite spectrometers, GOME1/ERS2 (1995-present), SCIAMACHY/ENVISAT (2002-present), and GOME2 (2006-present) provide a near global decadal data set of total ozone covering more than a decade. This data are very valuable for the detection of recovery in stratospheric ozone as expected from the levelling off of stratospheric chlorine. In order to detect such a signal be...

Constrained Application Protocol (CoAP) has been introduced as a simpler alternative to the Hypertext Transfer Protocol (HTTP) for connecting constrained smart objects to the Web. The adoption of the protocol depends on its relative advantage, and the cost-benefit associated with the use of the protocol is a significant factor affecting a protocol adoption decision. This paper aims at deepening...
