The concept of variability is not new in software engineering, but current research mostly remains vague about the overall variability concept when it comes to giving a clear overview of the dimensions of variability. In this paper we evaluate the core variability concept by proposing an...

This paper is a cross-study of service-learning projects executed by student groups in a 10-week course on software engineering. The principal benefits of service-learning are demonstrated by the groups in this setting. The course is structured to support the project activities; timely...

Existing data centers today are not ready to support IT organizations to meet the ever changing business demands. Therefore, next generation of data center like Software Defined Data Center (SDDC) is explored and expected to come to rescue. However, SDDC is relatively new since its inception in...

We develop a model to investigate the manner in which the pricing, profitability and protection strategies of the seller of a proprietary digital good respond to changing market conditions. Specifically, we investigate how the optimal strategy of a seller of proprietary software (such as...

The success of an outsourced software testing effort is a function of a number of factors, not all of which are easily measurable. Traditional metrics used for this have tended to focus on objective attributes such as “productivity per tester” but have generally ignored more subjective...

An Integrated Library Management System is a computer-based system used to manage internal and external resources including tangible assets, financial resources, materials, and human resources. It performs library automation and collection development tasks broken down into different modules...

This paper describes an approach for implementing earned value (EV) management tracking on small software development projects. Small projects are difficult EV applications because work must be tracked down at the task level so it can be costed out and used as a basis for the budgeted and...

We define ‘business primitives' as low-level operations from which higher-level, more complex operations can be constructed. We set out to understand what most businesses in Kenya -- the land of the ubiquitous M-PESA -- do every day that could be simplified and reinforced through software. We...

There is pressing need for effectively integrating information from an ever increasing number of available sources both on the web and in other existing systems. A key difficulty of achieving this goal comes from the pervasive heterogeneities in all levels of information systems. Existing and...

Using a unique data set we empirically examine which factors explain output per contributor in open source projects. We find that the output per contributor of open source programs is much higher when licenses are less restrictive. Further examination suggests that the difference in output per...
