In the recent years, customer relationship management (CRM) has being depictured by the software vendors as a cure-alls for the enterprises which wish to acquire, maintain efficiently customer share and at last to gain more profit in globalized market with fierce competition. However, the currently popular CRM marketing practice often produces disappointing outcomes. The more popular this marke...

We present a quantitative approach for IT portfolio management. This is an approach that CMM level 1 organizations can use to obtain a corporate wide impression of the state of their total IT portfolio, how IT costs spent today project into the budgets of tomorrow, how to assess important risks residing in an IT portfolio, and to explore what-if scenarios for future IT investments. Our quantita...

Software as a Service (SaaS) is a promising approach for Small and Medium Enterprises (SMEs) firms, in particular those that are focused on growing fast and leveraging new technology, due to the potential benefits arising from its inherent scalability, reduced total cost of ownership and the ease of access to global innovations. This paper proposes a dynamic perspective on IS capabilities to un...

Our focus in this paper is to better understand how and why various governments in Europe are adopting, using and cocreating open source software. Our study involved in-depth interviews of key stakeholders from a number of European government agencies. The main findings lead us to understand and organize our analysis under four broad categories of criteria that motivated open source adoption. T...

Aspect-oriented advice increases the number of places one must consider during reasoning, since advice may affect all method calls and field accesses. MAO, a new variant of AspectJ, demonstrates how to simplify reasoning by allowing programmers, if they choose, to declare limits on the control and heap effects of advice. Heap effects, such as assignment to object fields, are specified using con...

In biparental birds, the relative contribution of the sexes to feeding their brood (provisioning share) is sometimes reported to vary with brood size. However, the explanation for changes in provisioning share are often ambiguous (particularly in correlational studies), while the variation in findings between studies remains poorly understood. In this study we examined how short-term, within-pa...

The philosophy of simplicity as a key value, underlying and driving design and decisions, is strategically important yet poorly understood and rarely systematically applied in IT. Instead, design principles attempt to focus predominantly on increased functionality within thinly disguised complexity, often at the expense of life cycle costs and total cost of ownership issues (e.g., training, sys...

I compare the incentives firms have to produce individual components compatible with components of other manufacturers instead of "systems" composed of components that are incompatible with components of competing manufacturers. I show that, even in the absence of positive consumption externalities ("network" externalities), prices and projits will be higher in the regime of compatibility. Equi...

The software development process is described in terms of cost or effort via cost drivers. Some scenarios are inadequately addressed because the available elements to describe them become inappropriate. Those scenarios comprise a great amount of effort at the conception stage and at managing perspectives and relationships. This work explores several aspects not considered as cost drivers that c...
