Scenarios are an effective means for eliciting, validating and documenting requirements. At the requirements level, scenarios describe sequences of interactions between the software-to-be and agents in the environment. Interactions correspond to the occurrence of an event that is…
My talk will present a personal and rather selective view of the state of the art of some aspects of dependability assessment for software-based systems. This short note gives a brief outline of the issues I shall address.
Real-world software engineers deal with complex problem. Yet many software engineering courses do not involve projects of enough complexity to give students such experience. We sense that service-learning projects, while difficult to manage and sustain, can serve a crucial role i…
Scenarios are often used for discovering requirements using established techniques, but how such scenarios are initially developed is not so well understood. This experience paper reports the application of one scenario-based approach - RESCUE - to discover requirements for DMAN,…
A fleet of emerging agile methods is both gaining popularity and generating lots of controversy. Real-world examples argue for (e.g. Highsmith and Cockburn, 2001) and against (e.g. Rakitin, 2001) agile methods. Several leading software engineering experts suggest that synthesizin…

Most object oriented applications that involve persistent data interact with a relational database. The most common interaction mechanism is a call level interface (CLI) such as ODBC or JDBC. While there are many advantages to using a CLI -- expressive power and performance being…
Research was conducted on using agile methods in software engineering education. This paper explores the perceptions of students from five different academic levels of agile practices. Information has been gathered through the collection of quantitative and qualitative data over …
COCONUT calibrates effort estimation models using an ex-haustive search over the space of calibration parameters in a COCOMO I model. This technique is much simpler than other effort estimation method yet yields PRED levels com-parable to those other methods. Also, it does so wit…
In this paper, we propose a method to help users avoid bugs in GUI applications. In particular, users would use the application normally and report bugs that they encounter to prevent anyone -- including themselves -- from encountering those bugs again. When a user attempts an ac…
Producing reliable and robust software has become one of the most important software development concerns in recent years. Testing is a process by which software quality can be assured through the collection of information. While testing can improve software reliability, current …
Predicting software quality as perceived by a customer may allow an organization to adjust deployment to meet the quality expectations of its customers, to allocate the appropriate amount of maintenance resources, and to direct quality improvement efforts to maximize the return o…
This paper describes an industrial study of an effort estimation method based on use cases, the Use Case Points method. The original method was adapted to incremental development and evaluated on a large industrial system with modification of software from the previous release. W…
Software systems evolve over time due to changes in requirements, optimization of code, fixes for security and reliability bugs etc. Code churn, which measures the changes made to a component over a period of time, quantifies the extent of this change. We present a technique for …
During software development it is helpful to obtain early estimates of the defect density of software components. Such estimates identify fault-prone areas of code requiring further testing. We present an empirical approach for the early prediction of pre-release defect density b…
In an integrated development environment, the ability to manage the evolution of a software system in terms of logical abstractions, compositions, and their interrelations is crucial to successful software development. This paper presents a novel framework and infrastructure, Mol…
Empirical Software engineering research has advanced in many parts of the world especially the western nations, but little has been contributed in this research domain by the developing nations such as Nigeria, the well-acclaimed 'Giant of Africa'. The fast growing software indus…
In this paper, we present our experiences gained from the course "Information Systems Development" which is entirely taught online at the Virtual Global University (VGU). We identify technical, economic, and pedagogical problems and challenges which are of general interest to any…

Model-based testing has become increasingly popular in recent years. Major reasons include: (1) the need for quality assurance for increasingly complex systems, (2) the emerging model-centric development paradigm, e.g., UML and MDA, with its seemingly direct connection to testing…
